GENERAL SAFETY INSTRUCTIONS

Operating a Mortiser can be dangerous if safety and

common sense are ignored. The operator must be

familiar with the operation of the tool. Read this manual

to understand this Mortiser. DO NOT operate this

Mortiser if you do not fully understand the limitations

of this tool. DO NOT modify this Mortiser in any way.

REMEMBER: Your personal safety is your

responsibility.

BEFORE USING THE MORTISER

To avoid serious injury and damage to the tool, read

and follow all of the Safety and Operating Instructions

before operating the Mortiser.

Some dust created by using power tools 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

equipment, such as those dust masks that are spe-

cially designed to filter out microscopic particles.

READ the entire Owner's Manual. LEARN how to

use the tool for its intended applications.

GROUND ALL TOOLS. If the tool is supplied with a

3-prong plug, it must be plugged into a 3-contact

electrical receptacle. The 3rd prong is used to

ground the tool and provide protection against

accidental electric shock. DO NOT remove the 3rd

prong. See Grounding Instructions.

AVOID A DANGEROUS WORKING ENVIRON-

MENT. DO NOT use electrical tools in a damp

environment or expose them to rain.

DO NOT use electrical tools in the presence of

flammable liquids or gasses.

ALWAYS keep the work area clean, well lit, and

organized. DO NOT work in an environment with

floor surfaces that are slippery from debris, grease,

and wax.

KEEP VISITORS AND CHILDREN AWAY. DO NOT

permit people to be in the immediate work area,

especially when the electrical tool is operating.

10.

11.

DO NOT FORCE THE TOOL to perform an opera-

tion for which it was not designed. It will do a safer

and higher quality job by only performing operations

for which the tool was intended.

WEAR PROPER CLOTHING. DO NOT wear loose

clothing, gloves, neckties, or jewelry. These items

can get caught in the machine during operations

and pull the operator into the moving parts. The

user must wear a protective cover on their hair, if

the hair is long, to prevent it from contacting any

moving parts.

ALWAYS WEAR EYE PROTECTION. Any power

tool can throw debris into the eyes during opera-

tions, which could cause severe and permanent

eye damage. Everyday eyeglasses are NOT safety

glasses. ALWAYS wear Safety Goggles (that

comply with ANSI standard Z87.1) when operating

power tools. Safety Goggles are available at Sears

Retail Stores.

ALWAYS WEAR HEARING PROTECTION.

Plain cotton is not an acceptable protective device.

Hearing equipment should comply with ANSI $3.19

Standards.

12. ALWAYS UNPLUG THE TOOL FROM THE ELEC-

TRICAL RECEPTACLE when making adjustments,

changing parts or performing any maintenance.

13. KEEP PROTECTIVE GUARDS IN PLACE AND IN

WORKING ORDER.

14.

18.

19.

AVOID ACCIDENTAL STARTING. Make sure that

the power switch is in the "OFF" position before

plugging in the power cord to the electrical

receptacle.

REMOVE ALL MAINTENANCE TOOLS from the

immediate area prior to turning the tool "ON".

USE ONLY RECOMMENDED ACCESSORIES.

Use of incorrect or improper accessories could

cause serious injury to the operator and cause

damage to the tool. If in doubt, check the instruction

manual that comes with that particular accessory.

NEVER LEAVE A RUNNING TOOL UNATTENDED.

Turn the power switch to the "OFF" position. DO

NOT leave the tool until it has come to a complete

stop.

DO NOT STAND ON A TOOL. Serious injury could

result if the tool tips over or you accidentally contact

the tool.

22.EACH AND EVERY TIME, CHECK FOR DAM-

AGED PARTS PRIOR TO USING THE TOOL.

Carefully check all guards to see that they operate

properly, are not damaged, and perform their

intended functions. Check for alignment, binding or

breaking of moving parts. A guard or other part that

is damaged should be immediately repaired or

replaced.

23. CHILDPROOF THE WORKSHOP AREA by remov-

ing switch keys, unplugging tools from the electrical

receptacles, and using padlocks.

24. DO NOT OPERATE TOOL IF UNDER THE INFLU-

ENCE OF DRUGS OR ALCOHOL.

25. SECURE ALL WORK. When it is possible, use

clamps or jigs to secure the workpiece. This is safer

than attempting to hold the workpiece with your

hands.

26. STAY ALERT, WATCH WHAT YOU ARE DOING,

AND USE COMMON SENSE WHEN OPERATING

A POWER TOOL. DO NOT USE A TOOL WHILE

TIRED OR UNDER THE INFLUENCE OF DRUGS,

ALCOHOL, OR MEDICATION. A moment of in-

attention while operating power tools may result in

serious personal injury.

27. ALWAYS WEAR A DUST MASK TO PREVENT

INHALING DANGEROUS DUST OR AIRBORNE

PARTICLES, including wood dust, crystalline silica

dust and asbestos dust. Direct particles away

from face and body. Always operate tool in well

ventilated area and provide for proper dust removal.

Use dust collection system whenever possible.

Exposure to the dust may cause serious and

permanent respiratory or other injury, including

silicosis (a serious lung disease), cancer, and

death. Avoid breathing the dust, and avoid pro-

longed contact with dust. Allowing dust to get into

your mouth or eyes, or lay on your skin may pro-

mote absorption of harmful material. Always use

properly fitting NIOSH/OSHA approved respiratory

protection appropriate for the dust exposure, and

wash exposed areas with soap and water.

28. USE A PROPER EXTENSION CORD IN GOOD

CONDITION. When using an extension cord, be

sure to use one heavy enough to carry the current

your product will draw. Please see minimum recom-

mended gauge for extension cords (AWG) table for

correct sizing of an extension cord. If in doubt, use

the next heavier gauge.

GUIDELINES FOR EXTENSION CORDS

The smaller the gauge number, the larger diameter of

the extension cord is. If in doubt of the proper size of an

extension cord, use a shorter and thicker cord. An

undersized cord will cause a drop in line voltage result-

ing in a loss of power and overheating. USE ONLY A

3-WIRE EXTENSION CORD THAT HAS A 3-PRONG

GROUNDING PLUG AND A 3-POLE RECEPTACLE

THAT ACCEPTS THE TOOL'S PLUG.

If you are using an extension cord outdoors, be sure

it is marked with the suffix "W-A" ("W" in Canada) to

indicate that it is acceptable for outdoor use.

Be sure your extension cord is properly sized, and

in good electrical condition. Always replace a damaged

extension cord or have it repaired by a qualified person

before using it.

Protect your extension cords from sharp objects,

excessive heat, and damp or wet areas.

THIS TOOL MUST BE GROUNDED WHILE IN USE

TO PROTECT THE OPERATOR FROM ELECTRIC

SHOCK.

IN THE EVENT OF A MALFUNCTION OR BREAK-

DOWN, grounding provides the path of least resistance

for electric current and reduces the risk of electric

shock. This tool is equipped with an electric cord that

has an equipment-grounding conductor and a ground-

ing plug. The plug MUST be plugged into a matching

electrical receptacle that is properly installed and

grounded in accordance with ALL local codes and

ordinances.

DO NOT MODIFY THE PLUG PROVIDED. If it will not

fit the electrical receptacle, have the proper electrical

receptacle installed by a qualified electrician.

IMPROPER ELECTRICAL CONNECTION of the equip-

ment-grounding conductor can result in risk of electric

shock. The conductor with the green insulation (with or

without yellow stripes) is the equipment-grounding

conductor. DO NOT connect the equipment-grounding

conductor to a live terminal if repair or replacement of

the electric cord or plug is necessary.

CHECK with a qualified electrician or service personnel

if you do not completely understand the grounding

instructions, or if you are not sure the tool is properly

grounded.

The motor supplied with your Mortiser is a 120-volt,

single-phase motor. It is shipped wired for 120-volt

application. Never connect the green wire to a live

terminal.

USE ONLY A 3-WIRE EXTENSION CORD THAT HAS

A 3-PRONG GROUNDING PLUG AND A 3-POLE

RECEPTACLE THAT ACCEPTS THE TOOL'S PLUG.

REPLACE A DAMAGED OR WORN CORD

IMMEDIATELY.

This tool is intended for use on a circuit that has an

electrical receptacle as shown in FIGURE 1. FIGURE 1

shows a 3-wire electrical plug and electrical receptacle

that has a grounding conductor. If a properly grounded

electrical receptacle is not available, an adapter as

shown in FIGURE 2 can be used to temporarily connect

this plug to a 2-contact ungrounded receptacle. The

adapter has a rigid lug extending from it that MUST be

connected to a permanent earth ground, such as a

properly grounded receptacle box. THIS ADAPTER IS

PROHIBITED IN CANADA.

CAUTION: In all cases, make certain the electrical

receptacle in question is properly grounded. If you are

not sure have a certified electrician check the electrical

receptacle.

This Mortiser is for indoor use only. Do not expose to

rain or use in damp locations.

I/i

The Fence can be moved in and out to accommodate

various size workpieces.

1. To move Fence, loosen Lock Knob (A) See Figure 24.

2. Loosen Fence Lock Handle (C) until the Fence

Glide Shaft (B) can slide freely.

3. Slide Fence in or out to the desired location.

4. Tighten Fence Lock Handle to lock the fence in place.

The purpose of the holddown is to prevent the work-

piece from lifting as the chisel is raised up.

1. To adjust, loosen set screw (A). See Figure 25.

2. Position Holddown (B) until it just touches the top of

the workpiece (C) and allows the workpiece to slide

left or right.

NOTE: The holddown can be turned upside down to

accommodate thicker workpieces.

3. Once Holddown is in position, retighten set screw.

MICRO ADJUST ASSEMBLY

Sometimes it is necessary to move the fence in small

increments. When this is the case, the Micro Adjust

Assembly should be used.

1. Make sure that the Lock Knob (A) is tightened

down on the Fence Glide Shaft (B). See Figure 24.

2. Loosen the Fence Lock Handle (C) so that the

Fence (D) may slide smoothly.

Rotate the Adjustment Knob (E) clockwise to move

the fence in towards the mortiser column. Rotate

counterclockwise to move the fence away from the

mortiser column.

SETTING CHISEL SQUARE TO FENCE

Before using the mortiser, it is important to make sure

that the chisel is square to the fence.

Make sure that the mortiser is disconnected from the

power source.

Figure 26

SLIDING FIT BETWEEN HEAD

AND COLUMN

A dovetail gib is provided on the rear of the head to

insure a good sliding fit between the head and the

column when the head is raised and lowered. This

should be set at the factory and should not need

adjustment. If adjustment is necessary, perform the

following steps.

Figure 27

Place a square against the face of the fence (A).

See Figure 26.

Check to see if left side of chisel (B) is square to

the face of the fence.

If not square, loosen set screw (C) and reposition

chisel until the left side of the chisel is flat against

the square.

4. Retighten set screw.

Loosen 2 allen head screws (A) in the dovetail gib

(B) only slightly (less than 1/8 turn) using provided

6mm L-Handle Allen Wrench. See Figure 27.

2. Turn adjusting screws (C) clockwise to make a

tighter fit, turn counterclockwise for a looser fit.

NOTE: Correct adjustment is when a good snug sliding

fit is obtained without any side movement between the

gib and the column. This adjustment should not be too

tight that it restricts the sliding movement or too loose

that it affects accuracy.

3. Once proper fit is achieved, retighten allen head

screws.

ATTACHING COLUMN EXTENSION

The column can be extended for the purpose of mortis-

ing taller workpieces

Make certain the machine is disconnected from the

power source.

Figure 28

Snap off the hydraulic cylinder (G) and remove the

lower junction screw (H). See Figure 29.

Remove the 4 M8 x 30mm Hex Head screws (I)

and remove the mortiser column (J) from the

base (K).

Remove the 4 M8 Lock Washers and 4 M8 Flat

Washers from the 4 M8 x 30mm Hex Head screws

and put them on the 4 M8 x 80mm Hex Head

Screws.

Figure 30

Remove the 2 M4 x 8mm Pan Head Screws (A)

that fasten the MJcroAdjust Assembly (B).

See Figure 28.

Loosen Lock Knob (C) and remove micro adjust

assembly from the Fence Glide Shaft (D).

Remove Short Fence Lock Handle (E).

Slide Fence Glide Shaft completely out of the

mortiser column (F).

Line up the holes in the spacer block (L) with the

holes in the base. See Figure 30.

Place mortiser column over the spacer block and

fasten to base using the 4 M8 x 80ram Hex Head

Screws, 4 M8 Lock Washers and 4 M8 Flat

Washers.

Reinstall lower junction screw and attach hydraulic

cylinder.

Slide Fence Glide Assembly into the hole in the

Spacer Block.

Thread Long Fence Lock Handle (M) into spacer

block.

Place Micro Adjust Assembly over the Fence Glide

Shaft and fasten to the mortiser column using the

2 M4 x 8mm Pan Head Screws and 2 M4 Flat

Washers.

ROTATING COLUMN 180 DEGREES

Sometimes a workpiece may be too large to fit between

the base and the chisel. When this is the case, you

can rotate the column of the mortiser 180 degrees, as

shown, and perform the work off of a bench or floor.

Figure 31

USING AUXILIARY WOOD FENCE

When mortising an extra high workpiece, an auxiliary

fence can be fastened to the fence with wood screws

(not provided) through the holes in the fence. This

provides additional support for the workpiece during

mortising operation.

Figure 32

When rotating column 180 Degrees, you must fasten

the machine to a supporting surface. See FASTENING

MACHINE TO SUPPORTING SURFACE.

1. To rotate the column, remove the four M8 x 30mm

Hex Head Screws that bolt the mortiser column (A)

to the base (B). See Figure 31.

2. Rotate Column 180 degrees.

3. Replace four M8 x 30mm Hex Head Screws.

To attach a wooden auxiliary fence, place auxiliary

fence (A) up against the face of the main fence (B).

See Figure 32.

Fasten auxiliary fence to main fence through the

holes (C) in the main fence using wood screws

(not provided).

Place workpiece (D) up against auxiliary fence and

secure using the holddown (E).
