The manufacturer will not be held liable for injury or property damage

from negligence, improper training, machine modifications or misuse.

Some dust created by power sanding, sawing, grinding, drilling, and

other construction activities contains chemicals known to the State

of California to cause cancer, birth defects or other reproductive

harm. Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you

do this type of work. To reduce your exposure to these chemicals:

Work in a well ventilated area, and work with approved safety equip-

ment, such as those dust masks that are specially designed to filter

out microscopic particles.

NOTICE

Safety Instructions for Machinery

SECTION 1: SAFETY

Model T27417 (Mfd. Since 09/15)

-9-

WEARING PROPER APPAREL. Do not wear

clothing, apparel or jewelry that can become

entangled in moving parts. Always tie back or

cover long hair. Wear non-slip footwear to reduce

risk of slipping and losing control or accidentally

contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery

operations may cause cancer, birth defects, or

long-term respiratory damage. Be aware of dust

hazards associated with each workpiece mate-

rial. Always wear a NIOSH-approved respirator to

reduce your risk.

HEARING PROTECTION. Always wear hear-

ing protection when operating or observing loud

machinery. Extended exposure to this noise

without hearing protection can cause permanent

hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on

machinery can become dangerous projectiles

upon startup. Never leave chuck keys, wrenches,

or any other tools on machine. Always verify

removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use

this tool for its intended purpose—do not force

it or an attachment to do a job for which it was

not designed. Never make unapproved modifica-

tions—modifying tool or using it differently than

intended may result in malfunction or mechanical

failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing

and balance at all times when operating machine.

Do not overreach! Avoid awkward hand positions

that make workpiece control difficult or increase

the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and

bystanders at a safe distance from the work area.

Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce

accidental contact with moving parts or flying

debris. Make sure they are properly installed,

undamaged, and working correctly BEFORE

operating machine.

FORCING MACHINERY. Do not force machine.

It will do the job safer and better at the rate for

which it was designed.

NEVER STAND ON MACHINE. Serious injury

may occur if machine is tipped or if the cutting

tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement dur-

ing operation greatly increases risk of injury or

loss of control. Before starting, verify machine is

stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult

this owner’s manual or the manufacturer for rec-

ommended accessories. Using improper acces-

sories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the

risk of accidental injury, turn machine OFF and

ensure all moving parts completely stop before

walking away. Never leave machine running

while unattended.

MAINTAIN WITH CARE. Follow all maintenance

instructions and lubrication schedules to keep

machine in good working condition. A machine

that is improperly maintained could malfunction,

leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine

for damaged, loose, or mis-adjusted parts—or

any condition that could affect safe operation.

Immediately repair/replace BEFORE operating

machine. For your own safety, DO NOT operate

machine with damaged parts!

MAINTAIN POWER CORDS. When disconnect-

ing cord-connected machines from power, grab

and pull the plug—NOT the cord. Pulling the cord

may damage the wires inside. Do not handle

cord/plug with wet hands. Avoid cord damage by

keeping it away from heated surfaces, high traffic

areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time

you experience difficulties performing the intend-

ed operation, stop using the machine! Contact our

Technical Support at (570) 546-9663.

Model T27417 (Mfd. Since 09/15)

Additional Safety for Spindle/Edge Sanders

Serious injury or death can occur from fingers, clothing, jewelry or hair getting entangled

in rotating spindle or other moving components. Abrasion injuries can occur from touching

rotating sanding drum with bare skin. Workpieces thrown by drum can strike operator or

bystanders with moderate force, causing impact injuries. Long-term respiratory damage can

occur from using sander without proper use of a respirator. To reduce the risk of these hazards,

operator and bystanders MUST completely heed the hazards and warnings below.

AVOIDING ENTANGLEMENT. DO NOT wear

loose clothing, gloves, or jewelry, and tie back

long hair. Keep all guards in place and secure.

WORKPIECE INSPECTION. Nails, staples,

knots, or other imperfections in workpiece can

be dislodged and thrown from sander at high rate

of speed into operator or bystanders, or cause

damage to sanding sleeves, drum, or belts. Never

sand stock that has embedded foreign objects or

questionable imperfections.

TABLE INSERTS. A pinch point for fingers and

workpieces exists in the gap between table and

oscillating drum or belt. Always use table insert

that fits closest to diameter of installed drum to

keep this gap as small as possible and reduce

risk of injury.

POWER DISCONNECT. An accidental startup

while changing sleeves can result in entangle-

ment or abrasion injuries. Always disconnect

machine from power source before changing

sanding sleeve to avoid this risk.

WORKPIECE INTEGRITY. Sanding fragile

workpieces can result in loss of control, resulting

in entanglement, impact injuries, or damage to

the sanding sleeve, drum, or belt. Only sand solid

workpieces that can withstand power sanding

forces. Make sure shape of workpiece is properly

supported; avoid sanding workpieces without flat

bottom surfaces unless some type of jig is used to

maintain support and control when sanding force

is applied.

HAND PLACEMENT. Rotating sanding drums/

belts can remove a large amount of flesh in a few

seconds. Always keep hands away from drum/

belt during operation. Never touch moving drum

on purpose. Use a brush to clean table of sawdust

and chips.

FEEDING WORKPIECE. Forcefully jamming

workpiece into sanding surface could cause

workpiece to eject back at operator or damage

machine. Always allow spindle to reach full speed.

Firmly hold workpiece with both hands and ease it

against spindle using light pressure.

FEED DIRECTION. Feeding workpiece incor-

rectly can cause it to be thrown from machine,

allowing your hands to slip into the rotating drum

or striking yourself or bystanders. To reduce

these risks, feed workpiece against direction of

rotation, and never sand tapered or pointed stock

with point facing feed direction.

SANDING SLEEVE/BELT CONDITION. Worn

or damaged sanding sleeves/belts can tear apart

and become entangled in spindle or other moving

parts, resulting in subsequent injuries from opera-

tor loss of workpiece control. Replace worn or

damaged sanding sleeves/belts promptly.

SANDING DUST. Sanding creates large amounts

of dust and flying chips that can lead to eye injury

or serious respiratory illness. Reduce your risk by

always wearing approved eye and respiratory pro-

tection when using sander. Never operate without

adequate dust collection system in place and run-

ning. However, dust collection is not a substitute

for using a respirator.

SECTION 2: POWER SUPPLY

Availability

Before installing the machine, consider the avail-

ability and proximity of the required power supply

circuit. If an existing circuit does not meet the

requirements for this machine, a new circuit must

be installed. To minimize the risk of electrocution,

fire, or equipment damage, installation work and

electrical wiring must be done by an electrician or

qualified service personnel in accordance with all

applicable codes and standards.

Electrocution, fire, shock,

or equipment damage

may occur if machine is

not properly grounded

and connected to power

supply.

Full-Load Current Rating

The full-load current rating is the amperage a

machine draws at 100% of the rated output power.

On machines with multiple motors, this is the

amperage drawn by the largest motor or sum of all

motors and electrical devices that might operate

at one time during normal operations.

Full-Load Current Rating at 120V .... 3.5 Amps

The full-load current is not the maximum amount

of amps that the machine will draw. If the machine

is overloaded, it will draw additional amps beyond

the full-load rating.

If the machine is overloaded for a sufficient length

of time, damage, overheating, or fire may result—

especially if connected to an undersized circuit.

To reduce the risk of these hazards, avoid over-

loading the machine during operation and make

sure it is connected to a power supply circuit that

meets the specified circuit requirements.

For your own safety and protection of

property, consult an electrician if you are

unsure about wiring practices or electrical

codes in your area.

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will

be running on the circuit at a time. If machine will

be connected to a shared circuit where multiple

machines may be running at the same time, con-

sult an electrician or qualified service personnel to

ensure circuit is properly sized for safe operation.

A power supply circuit includes all electrical

equipment between the breaker box or fuse panel

in the building and the machine. The power sup-

ply circuit used for this machine must be sized to

safely handle the full-load current drawn from the

machine for an extended period of time. (If this

machine is connected to a circuit protected by

fuses, use a time delay fuse marked D.)

120V Circuit Requirements

This machine is prewired to operate on a power

supply circuit that has a verified ground and meets

the following requirements:

Nominal Voltage .................... 110V, 115V, 120V

Cycle ..........................................................60 Hz

Phase ........................................... Single-Phase

Power Supply Circuit ......................... 15 Amps

Serious injury could occur if you connect

machine to power before completing setup

process. DO NOT connect to power until

instructed later in this manual.

Model T27417 (Mfd. Since 09/15)

Extension CordsPolarized Plug

This tool is double-insulated and therefore does

not have a grounding wire or plug. The two-

pronged, NEMA 1-15 plug has a polarized end;

this means that one prong (the neutral connec-

tor) is wider than the other (the hot connector).

Polarized plugs must be used only with polarized

receptacles. Do not attempt to plug this machine

into a non-polarized receptacle. If a polarized

receptacle is not available, a qualified electri-

cal technician will have to install one before the

machine can be plugged in.

Figure 6. Typical 1-15 plug and receptacle.

5-15 Receptacle

1-15 Plug

Neutral

Hot

When using extension cords, make sure the cords

are rated for outdoor use. Outdoor use cords are

marked with a "W-A" or a "W" to signify their rat-

ing. Always check to make sure that the extension

cords are in good working order and free of any

type of damage, such as exposed wires, cuts,

creased bends, or missing prongs.

Extension cords cause voltage drop, which may

damage electrical components and shorten motor

life. Voltage drop increases as the extension cord

size gets longer and the gauge size gets smaller

(higher gauge numbers indicate smaller sizes.

When using extension cords, always choose the

shortest cord possible, with the greatest-sized

gauge.

Below is a list of minimum gauge sizes needed for

running this tool at different lengths:

25 Feet ...................................................16 AWG

50 Feet ...................................................14 AWG

Note: We do not recommend using extension

cords longer than 50 feet.

unsupervised use.

Workbench Load

Refer to the Machine Data Sheet for the weight

and footprint specifications of your machine.

Some workbenches may require additional rein-

forcement to support the weight of the machine

and workpiece materials.

Consider anticipated workpiece sizes and addi-

tional space needed for auxiliary stands, work

tables, or other machinery when establishing a

location for this machine in the shop. Below is

the minimum amount of space needed for the

machine.

Another option is a "direct mount" (see example

below) where the machine is secured directly to

the workbench with lag screws and washers.

The base of this machine has mounting holes

that allow it to be fastened to a workbench or

other mounting surface to prevent it from moving

during operation and causing accidental injury or

damage.

The strongest mounting option is a "Through

Mount" (see example below) where holes are

drilled all the way through the workbench—and

hex bolts, washers, and hex nuts are used to

secure the machine in place.

Assembly

Place the spindle nut, table inserts, sanding

drums and sleeves, spindle washers, edge-sand-

ing attachment, and spindle nut wrench in the

appropriate accessory slots beneath the table

(see Figures 11–12). A sanding drum does not

need to be installed until after the test run.

Figure 11. Assembled sander (front).

Figure 12. Assembled sander (rear).

Dust Collection

To connect dust collection system to machine:

1. Fit 1

⁄2" dust hose over dust port, as shown in

Figure 13, and secure with a hose clamp.

2. Tug the hose to make sure it does not come

off.

Note: A tight fit is necessary for proper

performance.

Recommended CFM at Dust Port: 100 CFM

Do not confuse this CFM recommendation with

the rating of the dust collector. To determine the

CFM at the dust port, you must consider these

variables: (1) CFM rating of the dust collector,

(2) hose type and length between the dust col-

lector and the machine, (3) number of branches

or wyes, and (4) amount of other open lines

throughout the system. Explaining how to cal-

culate these variables is beyond the scope of

this manual. Consult an expert or purchase a

good dust collection "how-to" book.

This machine creates a lot of wood chips/

dust during operation. Breathing airborne

dust on a regular basis can result in perma-

nent respiratory illness. Reduce your risk

by wearing a respirator and capturing the

dust with a dust collection system.

Test Run

Once assembly is complete, test run the machine

to ensure it is properly connected to power and

safety components are functioning correctly.

If you find an unusual problem during the test run,

immediately stop the machine, disconnect it from

power, and fix the problem BEFORE operating the

machine again. The

Troubleshooting

table in the

SERVICE section of this manual can help.

DO NOT start machine until all preceding

setup instructions have been performed.

Operating an improperly set up machine

may result in malfunction or unexpect-

ed results that can lead to serious injury,

death, or machine/property damage.

Serious injury or death can result from

using this machine BEFORE understanding

its controls and related safety information.

DO NOT operate, or allow others to operate,

machine until the information is understood.

To test run machine:

1. Clear all setup tools away from machine.

2. Connect machine to power supply.

3. Turn machine ON, verify motor operation,

and then turn machine OFF.

The motor should run smoothly and without

unusual problems or noises.

4. Remove switch-disabling key, as shown in

Figure 14.

5. Try to start machine with paddle switch. The

machine should not start.

— If machine does not start, switch disabling

feature is working as designed.

— If machine does start, immediately stop

machine. The switch disabling feature is

not working correctly. This safety feature

must work properly before proceeding with

regular operations. Call Tech Support for

help.

Congratulations! The test run is complete.

The sander is ready for operation.

Figure 14. Removing switch key from paddle

switch.

The Test Run consists of verifying the following:

1) The motor powers up and runs correctly

2) The switch-disabling key safety feature works

correctly

SECTION 4: OPERATIONS

Disabling Switch

The switch can be disabled by removing the key,

as shown below. Disabling the switch in this man-

ner can prevent unauthorized operation of the

machine, which is important if it is not kept inside

an access-restricted building or in a location

where children may be present.

IMPORTANT:

Disabling the switch only restricts

its function. It is not a substitute for disconnecting

machine from power when adjusting or servicing.

Figure 15. Disabling switch by removing key.

Children or untrained people can be

seriously injured by this machine

. This

risk increases with unsupervised operation.

To help prevent unsupervised operation,

always disable

switch before leaving

machine unattended. Make sure to place

key in a well-hidden or secure location!

To reduce your risk of

serious injury, read this

entire manual BEFORE

using machine.

To reduce risk of eye injury from flying

chips or lung damage from breathing dust,

always wear safety glasses and a respirator

when operating this machine.

If you are not experienced with this type

of machine, WE STRONGLY RECOMMEND

that you seek additional training outside of

this manual. Read books/magazines or get

formal training before beginning any proj-

ects. Regardless of the content in this sec-

tion, Grizzly Industrial will not be held liable

for accidents caused by lack of training.

Installing Sanding Drum/Sleeve

The Model T27417 comes with

⁄2",

⁄4", 1", 1

⁄2",

and 2" sanding sleeves for sanding a variety of

different curves.

Spindle sanding is performed to sand inside

curves and irregular shapes. The oscillating spin-

dle moves up and down as it rotates to help cre-

ate a smooth surface that accurately follows your

layout line.

To use the spindle sander, you must first config-

ure the machine for spindle sanding by installing

the appropriate sanding drum/sleeve for your

operation.

Note: The 1/2" sanding sleeve does not use a

sanding drum, but mounts directly to the spindle

shaft.

1. Turn sander ON and allow it to reach full

speed.

2. Use both hands to maintain control of

workpiece, and guide it against rotation of

spindle, as shown in Figure 18. DO NOT

force workpiece against sanding sleeve.

Allow the machine to do the work.
