SAFETY RULES
As with all power tools there is a certain amount of
hazard involved with the operation and use of the
tool. Use the tool with the respect and caution demanded where safety precautions are concerned.
This will considerably lessen the possibility of personal injury. When normal safety precautions are
overlooked or completely ignored, personal injury
to the operator can result.
1. KNOW YOUR TOOL. Read the owners
manual carefully. Learn the tools applications and
limitations, as well as the specific potential hazards peculiar to it.
2. KEEP GUARDS IN PLACE and maintained
in working order.
3. GROUND ALL TOOLS. If tool is equipped
with three-prong plug, it should be plugged into a
three-hole electrical receptacle. If an adapter is
used to accommodate a two-prong receptacle, the
adapter plug must be attached to a known ground.
Never remove the third prong.
4. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to see that
keys and adjusting wrenches are removed from
tool before turning it on.
5. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
6. AVOID DANGEROUS ENVIRONMENT.
Dont use power tools in damp or wet locations, or
expose them to rain. Keep work area well lighted.
7. KEEP CHILDREN AND VISITORS AWAY. All
children and visitors should be kept a safe distance
from work area.
12. USE SAFETY GLASSES. Also use face or
dust mask if cutting operation is dusty.
13. SECURE WORK. Use clamps or a vise to
hold work when practical. Its safer than using your
hand and frees both hands to operate tool.
14. DONT OVERREACH. Keep your proper foot-
ing and balance at all times.
15. MAINTAIN TOOLS IN TOP CONDITION.
Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and
changing accessories.
16. DISCONNECT TOOLS before servicing and
when changing accessories such as chisel and bit.
17. USE RECOMMENDED ACCESSORIES.
Consult the owners manual for recommended accessories. The use of improper accessories may
cause hazards.
18. AVOID ACCIDENTAL STARTING. Make sure
switch is in OFF position before plugging in cord.
19. NEVER STAND ON TOOL. Serious injury
could occur if the tool is tipped or if the cutting tool
is accidentally contacted.
20. CHECK DAMAGED PARTS. Before further
use of the tool, a guard or other part that is damaged should be carefully checked to ensure that it
will operate properly and perform its intended function - check for alignment of moving parts, binding
of moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation.
A guard or other part that is damaged should be
properly repaired or replaced.
8. MAKE WORKSHOP CHILDPROOF - with
padlocks, master switches, or by removing starter
keys.
9. DONT FORCE TOOL. It will do the job better and be safer at the rate for which it was designed.
10. USE RIGHT TOOL. Dont force tool or attachment to do a job it was not designed for.
11. WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, or jewelry that can
get caught in moving parts. Nonslip footwear is
recommended. Wear protective hair covering to
contain long hair
4
21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Dont leave tool
until it comes to a complete stop.
22. DRUGS, ALCOHOL, MEDICATION. Do not
operate tool while under the influence of drugs, alcohol, or any medication.

RECEIVING THE MORTISER
Remove mortiser and stand from the shipping cartons. Check for damage and ensure all parts are
intact. Any damage should be reported immediately to your distributor and shipping agent. Before assembling, read the manual thoroughly, familiarizing yourself with correct assembly and
maintenance procedures and proper safety precautions.
Contents of shipping cartons:
Unit shipped in two cartons.
Stand carton
1 Stand
1 Hardware package
Main Unit carton
1 Mortiser with motor
1 Operating handle
1 Chuck removing wrench
2 Handwheel handles
1 Chuck key
3 Chisel bushings
1 Wooden table
2 M6 x 20 Philips head screws
1 Chuck extension adaptor
head. Then lower the chisel approximately 1/16"
to 3/16", depending on the type of wood being
worked. Tighten the screw to hold chisel in place.
4. Push bit up through the chisel opening as far
as it will go. Lock the drill bit in place with the
chuck key.
5. Loosen screw and push chisel up against the
bushing, then tighten screw. This should provide
the proper distance between the points of the chisel
and the bit.
INSTALLATION
The mortiser should be secured to the stand with
four screws (provided) using the holes in the base.
Make sure there is enough room on each side of
the mortiser for the size stock you plan to use.
WARNING: THE MORTISER HAS A THREEPRONG PLUG AND REQUIRES A GROUNDED
OUTLET. IN THE EVENT OF A MALFUNCTION
OR BREAKDOWN, GROUNDING PROVIDES A
PATH OF LEAST RESISTANCE FOR ELECTRIC
CURRENT TO REDUCE THE RISK OF ELECTRIC
SHOCK.
IF YOU ARE NOT SURE WHETHER YOUR OUTLET IS PROPERLY GROUNDED, CONSULT A
QUALIFIED ELECTRICIAN.
ADJUSTMENTS
INSTALLING/REPLACING CHISEL & BIT
1. Loosen screw, Figure 2.
2. Insert chisel bushing (with the hole facing forward) into the head. Tighten the screw just enough
to hold the chisel in place.
NOTE: Set the slot in the side of the chisel to the
left or right, NOT to the front or back. This will allow chips to escape when cutting mortises.
3. Push the chisel up as far as possible into the
FIGURE 2
WORK STOP
The work stop can be mounted to either end of the
table through the holes in the back of the table, as
shown in Figure 3. It is tightened into place by
means of thumb screws.
FIGURE 3
6
CHUCK EXTENSION ADAPTOR
To lower the chuck with the adaptor proceed as
follows (Figure 4):
1. Remove chisel and bit.
2. Unscrew the chuck release nut which will
force the chuck off the shaft. (NOTE: It may be
necessary to hold the shaft stationary while turning the nut. This can be done by inserting a rod or
dowel into the hole in the chuck and allowing it to
wedge against the edge of the headstock.)
3. When the chuck is off, return the nut to its
original position on the shaft.
4. Push the optional adaptor onto the motor shaft
as shown. Then push the chuck onto the adaptor.
FIGURE 5
FIGURE 4
OPERATION
1. Set depth stop to the required depth of cut,
Figure 5.
2. Place workpiece on table and clamp it with
the vise. Use the left handwheel to move table forward or backward to suit the position of the mortise on the workpiece.
3. Adjust the table stops, Figure 6, according to
the length of cut required, then tighten the thumb
screws.
4. Turn on machine and feed chisel and bit
steadily into workpiece by pulling down the operating handle.
NOTE: The rate of feed must be fast enough to
prevent burning at the tip of the bit, but not so fast
as to cause the machine to slow or stall. The different rates of feed for different woods must be
learned through experience.
FIGURE 6
5. After the first cut, the workpiece is moved
along with the right handwheel for each successive cut. The direction of movement must allow
the chips to clear freely. Move the workpiece so
that the slot in the chisel is releasing chips into the
already cut part of the workpiece, Figure 7.
CAUTION: DO NOT HAVE THE CHISEL
SLOT AGAINST THE BLIND END OF THE MORTISE, AS THE CHIPS WILL NOT BE ABLE TO
CLEAR THE CHISEL. THIS CAN CAUSE OVERHEATING AND POSSIBLE BREAKAGE OF
CHISEL OR BIT.
7
FIGURE 7
When cutting deep mortises, make the cut in several stages of approximately 1" each, to allow chips
to clear. To prevent breakout at the back of the
workpiece when cutting through mortises, use a
piece of scrap material under the workpiece as
support.
MAINTENANCE
The Mortiser requires only minor maintenance,
such as cleaning and lubrication and routine adjustment and sharpening of the chisel and bit.
Dust the machine down after each use and, as necessary, use light applications of oil or grease to
lubricate linkages, moving parts, etc.
SHARPENING CHISEL & BIT
The chisel and bit should be kept sharp for best
performance. Blunt edges will give inaccurate
mortises and can cause overheating and breakage to chisel or bit. If chisel and bit are badly worn
and become difficult to sharpen, they should be
replaced.
FIGURE 8
FIGURE 9
1. Sharpen the bit by using a small, smooth file,
following the original shape of the bit. File the inside edge of the spur, the sides of the brad point,
and the cutting edge inwards toward the flute of
the bit. See Figure 8.
Do not file the outside edge of the spur as this will
affect the diameter of the bit.
2. Sharpen the chisel with a mortise chisel cutter with the correct size pilot. (Pilot size will differ
depending on the size of your chisel). Two or three
turns of the cutter in a carpenter's brace chuck
should be enough to sharpen the chisel, Figure 9.
3. Use a small, triangular, smooth file to relieve
the inner corners of the chisel, Figure 10, and remove any burrs from the outside of the chisel with
a fine oilstone.
