Standard Machinery Safety Instructions

For Your Own Safety,

Read Manual Before Operating Machine

The purpose of safety symbols is to attract your attention to possible hazardous conditions. This

manual uses a series of symbols and signal words intended to convey the level of importance of the

safety messages. The progression of symbols is described below. Remember that safety messages by

themselves do not eliminate danger and are not a substitute for proper accident prevention mea-

sures—this responsibility is ultimately up to the operator!

SAFETY

Standard Machinery Safety Instructions

-9-

Model W1839 & W1840 (For Machines Mfd. Since 3/16)

SAFETY

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

avoid accidental slips, which could cause loss

of workpiece control.

HAZARDOUS

DUST. Dust created while using

machinery may cause cancer, birth defects,

or long-term respiratory damage. Be aware of

dust hazards associated with each workpiece

material, and always wear a NIOSH-approved

respirator to reduce your risk.

HEARING PROTECTION.

Always wear hearing

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!

INTENDED USAGE.

Only use machine for its

intended purpose—never make modifications

without prior approval from Woodstock

International. Modifying machine or using

it differently than intended will void the

warranty and may result in malfunction or

mechanical failure that leads to serious

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.

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 during

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

recommended accessories. Using improper

accessories will increase 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.

CHECK DAMAGED PARTS. Regularly inspect

machine for any condition that may affect

safe operation. Immediately repair or replace

damaged or mis-adjusted parts before

operating machine.

MAINTAIN POWER CORDS. When disconnecting

cord-connected machines from power, grab

and pull the plug—NOT the cord. Pulling the

cord may damage the wires inside, resulting

in a short. 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

intended operation, stop using the machine!

SAFETY

Additional Safety for Benchtop Grinders

Serious injury or death can occur from impact injuries if a grinding wheel breaks apart during

operation. Rotating grinding wheels can easily remove skin or cause entanglement injuries if

clothing or apparel is caught in moving parts. Fingers can be pinched/cut by in-running pinch points.

Flying sparks can ignite explosive or flammable materials. To minimize risk of injury or death,

anyone operating machine MUST completely heed hazards and warnings below.

SAFE MOUNTING & WORK AREA. An unsecured

grinder may become dangerously out of control

during operation. Before use, verify grinder is

FIRMLY secured in a location free of explosive

or flammable materials.

STARTING GRINDER. If a wheel is damaged, it

will usually fly apart shortly after start-up. To

protect yourself, always stand to side of grinder

when turning it ON and allow it to run for at

least one minute before standing in front of it.

VISUAL INSPECTION. Verify that grinding wheels

are free of cracks, chips, or dents in wheel

surface before installing. Do not use wheel if

it has any of these problems or it could break

apart during operation.

WHEEL SPEED RATING. Before mounting a new

wheel, be sure wheel RPM rating is equal to

or higher than speed of grinder. Never use

unmarked wheels or wheels rated for lower

RPM than grinder.

VIBRATING WHEEL. Never use a wheel that

vibrates excessively. Replace wheel or shaft

bearings immediately.

SPARK DEFLECTOR GAP. Never allow gap

between end of spark deflector and

grinding wheel to exceed

⁄4”. If the

gap is larger, additional sparks and

abrasives will be expelled toward the

operator, which will increase the risk of injury.

TOOL REST POSITION. A large distance (gap)

between tool rest and wheel increases risk

of workpiece being pinched between wheel

and tool rest causing wheel breakage, loss

of control, and possible injury. Never allow

gap between tool rest and wheel to exceed

⁄8”. Replace grinding wheel when tool rest

gap becomes wider than

⁄8″ and no additional

adjustment can be made to tool rest.

SIDE & TOP GRINDING. Grinding on side of

wheels can cause them to crack and burst—

unless wheel is rated for side grinding.

Grinding on top of wheels greatly increases

risk of workpiece kickback. Always grind on

downward part of wheel.

SPINDLE NUT. Only tighten wheel spindle nut

enough to drive wheel and prevent slippage.

EYE SHIELDS. Place eye shields close to grinding

wheel and re-adjust as wheel wears down.

HAND & WHEEL CONTACT. Keep a firm grip

on workpiece and position your hands a safe

distance away when grinding. Anticipate when

workpiece will heat up, and cool it before it

becomes too hot to hold, or use an appropriate

clamp. Avoid wearing gloves as they may get

caught in grinding wheel and cause even more

serious entanglement injuries.

WHEEL FLANGES. Only use flanges included with

or designed for this grinder when mounting

wheels. Other flanges may not properly

secure wheel and cause an accident. Do not

use warped or damaged flanges, and always

use paper discs (blotters) between wheels

and flanges to reduce risk of flanges cracking

wheel when tightening.

EYE, FACE, & LUNG PROTECTION. Grinding

ejects small particles at a high rate of speed.

These particles can cause blindness, skin

injuries or respiratory damage. ALWAYS wear

approved clothing, safety goggles, face shield,

and a respirator for type of grinding to be

done.

RING TEST. Perform a “ring test” on grinding

wheels before installation to ensure they are

safe to use. A wheel that does NOT pass ring

test may break or fly apart during operation.

Model W1839 & W1840 (For Machines Mfd. Since 3/16)

ELECTRICAL

Circuit Requirements

This machine must be connected to the correct size and

type of power supply circuit, or fire or electrical damage

may occur. Read through this section to determine if an

adequate power supply circuit is available. If a correct

circuit is not available, a qualified electrician MUST install

one before you can connect the machine to power.

A power supply circuit includes all electrical equipment

between the breaker box or fuse panel in the building

and the machine. The power supply 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.)

Circuit Requirements for 120V

This machine is prewired to operate on a power supply

circuit that has a verified ground and meets the following

requirements:

Circuit Type ............... 110V/120V, 60 Hz, Single-Phase

Circuit Size ............................................. 15 Amps

Plug/Receptacle .................................... NEMA 5-15

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.

W1839 Full-Load Current Rating at 120V ........ 2.5 Amps

W1840 Full-Load Current Rating at 120V ...........5 Amps

The machine must be properly set up

before it is safe to operate. DO NOT

connect this machine to the power

source until instructed to do so later in

this manual.

Incorrectly wiring or grounding this

machine can cause electrocution, fire,

or machine damage. To reduce this risk,

only an electrician or qualified service

personnel should do any required

electrical work on this machine.

NOTICE

The circuit requirements listed in this

manual apply to

a dedicated circuit—

where only one machine will be running

at a time. If this machine will be

connected to a shared circuit where

multiple machines will be running at the

same time, consult with an electrician

to ensure that the circuit is properly

sized for safe operation.

-12-

Model W1839 & W1840 (For Machines Mfd. Since 3/16)

ELECTRICAL

Grounding Requirements

This machine MUST be grounded. In the event of certain

types of

malfunctions or breakdowns, grounding provides

a path of least resistance for electric current

to travel—in

order

to reduce the risk of electric shock.

Improper connection of the equipment-grounding

wire

will

increase

the risk of electric shock. The wire with green

insulation

(with/without yellow stripes) is the equipment-

grounding

wire. If repair or replacement of the power

cord or plug is necessary, do not connect the equipment-

grounding

wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel

you do not understand these grounding requirements,

or if

you are in doubt about whether the tool is

properly grounded.

If you ever notice that a cord or

plug is damaged or worn, disconnect it from power, and

immediately replace it with a new one.

Figure 2. NEMA 5-15 plug & receptacle.

DO NOT modify the provided plug or

use an adapter if the plug will not

fit the receptacle. Instead, have an

electrician install the proper receptacle

on a power supply circuit that meets

the requirements for this machine.

Extension Cords

We do not recommend using an extension cord with

this machine. Extension cords cause voltage drop, which

may damage electrical components and shorten motor

life. Voltage drop increases with longer extension cords

and smaller gauge sizes (higher gauge numbers indicate

smaller sizes).

Any extension cord used with this machine must contain a

ground wire, match the required

plug and receptacle, and

meet the following requirements:

Minimum Gauge Size at 120V ...................... 16 AWG

Maximum Length (Shorter is Better) ................50 ft.

For 120V Connection

This machine is equipped with a power cord that has an

equipment-grounding

wire and NE M A 5-15 grounding plug.

The plug

must only be inserted into a matching

receptacle

(

see Figure) that is properly installed and grounded in

accordance with local codes and ordinances.

SETUP

Machine Placement

Workbench Load

Refer to the Machine Specifications for the

weight and footprint specifications of your

machine. Some workbenches may require

additional reinforcement to support the weight

of the machine and workpiece materials.

Bench Mounting

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) 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.

Another option is a “Direct Mount” (see

example) where the machine is secured directly

to the workbench with lag screws and washers.

Consider anticipated workpiece sizes and

additional 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.

Mount the grinder to a workbench to avoid

accidental tipping. For portable bench grinding,

mount it to a heavy plywood base (at least 1"

thick) that is wide enough to prevent tipping or

rocking during use.

Before beginning the assembly process, refer to Items

Needed for Setup

and gather everything you need.

Ensure all parts have been properly cleaned of any

heavy-duty rust-preventative applied at the factory (if

applicable). Be sure to complete all steps in the assembly

procedure prior to performing the Test Run.

To assemble machine, do these steps:

1. Assemble safety shields (see Figure 9) using (4)

M4-.7 x 12 Phillips head screws, (4) M4-.7 flange

nuts, (2) safety shield mounting plates, (2) safety

shields, and (2) safety shield mounting brackets.

2. Attach safety shield assemblies to spark deflectors

(see Figure 10) using (2) M6-1 x 12 carriage bolts,

(2) 6mm flat washers, and (2) M6-1 knobs.

6mm lock washer, and (1) M6-1 x 18 knob bolt (see

Figure 12).

5. Assemble right tool rest using (1) right tool rest

bracket, (1) right tool rest, (1) 6mm flat washer, (1)

6mm lock washer, and (1) M6-1 x 18 knob bolt.

3. Attach each spark deflector/safety shield assembly

to grinder with (4) M5-.8 x 10 Phillips head screws,

(4) 5mm flat washers, and (4) 5mm lock washers

(see Figure 11).

6. Attach each tool rest assembly to grinder using (4)

M8-1.25 x 12 hex bolts and (4) 8mm flat washers

(see Figure 13).

Figure 14. Tool rest gap.

⁄16" –

⁄8"

The toll rest can be adjusted closer/farther from grinding

wheel or tilted and secured every 15° from 0°—75°.

The tool rest stabilizes the workpiece when grinding.

It must always be positioned correctly when using the

grinder to help prevent the operator's hands from being

pulled into grinding wheel.

Each tool rest features detents that allow it to lock at a

specific angle. To adjust a tool rest, loosen the knob bolt

(see Figure 13) several turns, pivot the tool rest to the

appropriate angle, position it

⁄16" away from the grinding

wheel, and then tighten knob bolt to secure setting.

As grinding wheel wears, shift tool rest closer to grinding

wheel to maintain a gap of

⁄16" –

⁄8" (see Figure 14).

IMPORTANT: If the gap reaches

⁄8" and the tool rest

cannot be adjusted any closer to the wheel, the grinding

wheel MUST be replaced before you can resume safely

operating grinder.

Tool Rest Adjustment

x 4

Figure 15. Spark deflector gap.

⁄8" –

⁄4"

The spark deflector prevents sparks from showering the top

of the workpiece and the operator's hands. As the wheel

wears, adjust the spark deflector closer to the grinding

wheel to maintain a gap of

⁄8"–

⁄4" (see Figure 15). If

the gap reaches

⁄4" and no additional adjustments can be

made, replace the grinding wheel.

Spark Deflector Adjustment

Some grinding wheels must be replaced before spark

deflector or tool rest reach their final adjustment. As

diameter of a grinding wheel is reduced, so is surface

speed. Grinding under these conditions can lead to

faster abrasive loss and poor grinding results. Always

follow wheel manufacturer's directions.

Never grind WITHOUT tool rest in place and properly

positioned. "Free hand" grinding or too large of a gap

between wheel and tool rest increases risk of pinching,

which may result in wheel breakage or operator injury.

Test Run

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.

DO NOT start machine until all

preceding setup instructions have been

performed. Operating an improperly set

up machine may result in malfunction

or unexpected results that can lead

to serious injury, death, or machine/

property damage.

Once assembly is complete, test run the machine to

ensure it is properly connected to power and safety

components are functioning properly.

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.

To test run machine, do these steps:

1. Clear all setup tools away from machine.

2. Connect machine to power supply.

3. Rotate variable-speed dial all the way left and turn

machine ON, verify motor operation, and slowly

rotate variable-speed dial to the right, then turn

machine OFF.

The motor should run smoothly and without unusual

noises.

4. Remove key from toggle switch (see Figure 16).

5. Try to start machine with switch.

Machine should NOT start. If it does start, the switch

disabling feature is not functioning properly and the

switch must be replaced.
