Unpacking
Piece Inventory
After all the parts have been removed from the
carton, you should have:
• Mortising Machine
The Model G3183 Hollow Chisel Mortiser is
shipped from the manufacturer in a carefully
packed carton. If you discover the machine is
damaged after you’ve signed for delivery, please
call Customer Service immediately for advice.
• Hydraulic Cylinder
• Handle Bar
• 5⁄8'' Chisel Bushing
• 3⁄4'' Chisel Bushing
Save the containers and all packing materials for
possible inspection by the carrier or its agent.
Otherwise filing a freight claim can be difficult.
• Chuck Key
• Spindle Extension
• Wood Table
• Hold Down
• Fence
Caution: The Model G3183 is a heavy machine,
45 lbs. shipping weight. DO NOT over-exert your-
self while unpacking or moving your machine –
get assistance. In the event that your Hollow
Chisel Mortiser must be moved up or down a
flight of stairs, be sure that the stairs are capable
of supporting the combined weight of people and
the machine.
• 4 & 5mm Allen Wrenches
• Flat Head Screw M6-1.0x20mm(2)
In the event that any non-proprietary parts are
missing (e.g. a nut or a washer...), we would be
glad to replace them, or, for the sake of expedi-
ency, replacements can be obtained at your local
hardware store.
When you are completely satisfied with the con-
dition of your shipment, you should inventory its
parts.

Clean up
Site Considerations
The column and other unpainted parts of the
Model G3183 are coated with a waxy oil that pro-
tects them from corrosion during shipment.
Remove the protective coating with mineral spir-
its and paper towels. Do not use gasoline or other
petroleum based solvents because of their
extremely low flash points. Do not use chlorine-
based solvents – if you happen to splash some
onto a painted surface, you’ll ruin the finish.
1. Mounting: We recommend mounting your
Hollow Chisel Mortiser to a bench. This will
prevent the machine from tipping over and to
allow for maximum leverage when mortising.
2. Working Clearances: Consider existing and
anticipated needs, size of material to be
processed through each machine, and
space for auxiliary stands, work tables or
other machinery when establishing a loca-
tion for your Hollow Chisel Mortiser.
WARNING!
Follow the safety rules listed below when
working with solvents:
3. Lighting and Outlets: Lighting should be
bright enough to eliminate shadow and pre-
vent eye strain. Electrical circuits should be
dedicated or large enough to handle amper-
age requirements. Outlets should be located
near each machine so power or extension
cords are clear of high-traffic areas. Observe
local electrical codes for proper installation
of new lighting, outlets, or circuits.
1. Read and follow all directions and warnings
on the solvent label.
2. Work only in a well ventilated area.
3. Do not work near any type of open flame
(e.g., pilot lights, kerosene heaters, and so
on).
4. DO NOT smoke while working with flamma-
ble material.
5. Paper towels from the cleaning process are
extremely combustible. Dispose of waste
towels so they do not create a fire hazard.

Circuit Requirements
Tools Required
The motor supplied with the Model G3183 is a
110V single-voltage motor, prewired for 110V.
Under normal use, the motor draws approximate-
ly 6 amps @ 110V. We recommend using a 15
amp circuit breaker or a 15 amp slow blow fuse
for 110V operation. This should be satisfactory
for normal use, while preventing motor damage
from high heat caused by overload. If frequent
circuit failures occur when using the Hollow
Chisel Mortiser, contact our service department
or your local electrical contractor. The Hollow
Chisel Mortiser cannot be wired for 220V opera-
tion.
The Model G3183 Hollow Chisel Mortiser has
been largely pre-assembled at the factory.
However, some components must be assembled
or installed after delivery. We have organized the
assembly process into steps. Please follow along
in the order in which we have presented them
here. We also recommend that you spend some
time with the diagrams and parts lists to become
familiar with all the parts before you begin.
Tools Required: Common hand tools are all that
are necessary to assemble this machine.
Specifically, you will need a screwdriver, 4mm
and 5mm hex wrenches (provided) and a Phillips
screwdriver.
This equipment must be grounded. Please
ensure that the Hollow Chisel Mortiser is continu-
ously grounded from the motor to the machine
frame and then to a known ground. Verify that
any existing electrical outlet and circuit you intend
to plug into is actually grounded. If it is not, it will
be necessary to run a separate 12 A.W.G. copper
grounding wire from the outlet to a known ground.
Under no circumstances should the grounding
pin from any three-pronged plug be removed.
Extension Cords: If used, extension cords must
be rated Hard Service (grade S) or better.
Conductor size must be 14 A.W.G. for cords up to
50 feet in length. Your extension cord must also
contain a ground wire and plug pin. Always repair
or replace extension cords if they become dam-
aged.
CAUTION: Be sure that your particular electrical
configuration complies with local and state codes.
The best way to ensure compliance is to check
with your local municipality or licensed electri-
cian.

bit extends between ⁄16'' and ⁄16'' below the
tip of the chisel edge. Once you have prop-
erly aligned the bit and chisel, tighten the
chuck with the chuck key provided in the
package.
Figure 8.
4. Insert the bit into the chisel, then insert both
through the bottom of the bushing. Loosen
the brass screw, if necessary, to allow the
chisel and bit to pass by. Push the chisel as
far as it will go into the head assembly.
Tighten the brass screw to hold the chisel in
position. Figure 9.
NOTE: If the bit extends beyond the maximum
3⁄16'' below the chisel, even when fully engaged in
the chuck, it will be necessary to shorten the
shank of the bit to achieve proper clearance.

SECTION 3: ADJUSTMENTS
Headstock
Fence
The handle bar on the Model G3183 Hollow
Chisel Mortiser raises and lowers the head by
rack-and-pinion gearing. The handle bar can be
adjusted for comfort and maximum leverage by
loosening the nut at the end of the pinion shaft
just enough for the right and left adjustable gears
to disengage. Figure 11.
The fence can be moved forward and backward
to adjust for each project. To move the fence,
loosen the lock handle at the side of the column,
move the fence to the desired position and re-
tighten the handle. Figure 12.
Figure 12.

Hold Down
Depth Stop
The hold down is designed to prevent the work-
piece from lifting when the chisel is retracted. The
hold down should be adjusted so it just comes in
contact with the workpiece – allowing it to move
side-to-side, but not up and down. To adjust the
hold down, loosen the setscrew at the vertical
post, move the hold down to the desired height
and tighten the setscrew. The hold down can be
flipped upside down to accommodate larger
stock. Figure 13.
The depth stop rod allows you to control the
depth of your mortise cuts by limiting the distance
the head can be lowered. To set the desired mor-
tising depth, lower the head until it is a proper dis-
tance from the table. Loosen the setscrew on the
left side of the head and drop the depth stop rod
until it touches the base.Tighten the setscrew.
Figure 14.
NOTE: Ensure that the hold down is centered so
its fingers do not interfere with chisel movement.
The vertical post is flattened on one side. Position
the hold down so the setscrew meets the flat sur-
face.
Figure 14.
Figure 13.

Two setscrews mounted just forward of the bolts
ensure that side-to-side movement is minimal. If
head displays excess wiggle from side-to-side,
loosen the locknuts and tighten the setscrews
until movement is eliminated. Tighten the lock-
nuts. Figure 16.
Head Adjustment
Proper adjustment of the head and column is
necessary to ensure that mortiser travel is
smooth and precise. Two bolts located at the
back of the head control the tightness of the head
and column. If movement of the head becomes
sloppy, tighten the bolts until the travel is smooth
and solid. Should the head movement become
too difficult, loosen the bolts until movement is
satisfactory. Figure 15.

SECTION 4: OPERATIONS
Safety Rules
•
Before machine inspection, maintenance or
changing accessories: Turn off switch, unplug
power cord and wait for all moving parts to
stop.
Earlier in this manual we covered general shop
and machine safety rules. This section will
address safety rules specific to your mortiser.
•
•
•
Keep hands away from the chisel and bit
while this tool is being operated.
•
•
•
Be sure to observe all electrical requirements
such as fuse sizing, wire sizing, machine
grounding and any other electrical considera-
tion.
Always have the chisel opening facing away
from the operator or the fence.
The bit should reach full speed before begin-
ning a cut.
Always wear eye protection while operating
this mortiser. Also use a respirator to avoid
breathing dust. All safety equipment must be
ANSI approved.
•
•
Always feed chisel evenly and smoothly.
Do not touch the chisel during the mortising
operation.
Always be aware of the condition of the wood
you are mortising. Pay particular attention to
knots, splits, and other potentially dangerous
areas.
•
Never leave the mortiser running unattended.
This sums up our review of safety guidelines.
Remember that every shop has its own specific
hazards. Be sure, above all else, to use good
common sense and reasonable caution each
time you start this Hollow Chisel Mortiser, or any
woodworking machinery. Proper safety stan-
dards rarely take any more time or energy when
followed religiously. Develop a habit of safety.
•
•
•
Never attempt to operate the mortiser with
bits or chisels that are dull or damaged. They
will burn the wood and cause it to bind.
Maintain the mortiser in proper working condi-
tion. Perform machine inspections and main-
tenance services promptly when called for.
Always put adjustment tools away after use.
Caution
Always wear ANSI-approved safety
glasses or goggles when operating
equipment. Do not allow visitors into
your workshop when testing or oper-
ating equipment.

Test Run
Mortising
Once the assembly is complete and the adjust-
ments are done to your satisfaction, you are
ready to test the machine.
1.
Place the workpiece on the table and adjust
so chisel is aligned correctly for desired
mortise cut.
Turn on the power supply at the main panel.
Press the START button. Make sure that your fin-
ger is poised on the STOP button, just in case
there’s a problem. The Hollow Chisel Mortiser
should run smoothly, with little or no vibration or
rubbing noises. Strange or unnatural noises
should be investigated and corrected before
operating the machine further.
2.
3.
Secure the fence so the workpiece is firmly
supported.
Position the hold down as described earlier,
so upward movement of the workpiece is
eliminated.
4.
5.
Turn power on.
WARNING: DO NOT attempt to investigate or
adjust the machine while it is running. Wait until
the machine is turned off, unplugged and all
working parts have come to a rest before you do
anything!
Lower the head by pulling the handle bar
down with your right hand, while supporting
the workpiece with your left hand. NOTE:
Be extremely careful to avoid the chisel with
your left hand. It is very sharp, and friction
will make it hot enough to cause burns to
your skin. Figure 17.
If noises occur that cannot be found by visual
inspection, feel free to contact our service depart-
ment for help.
Figure 17.
-16-

6. The chisel and bit will cause some smoking
as it contacts the workpiece. This is caused
by friction heating resins in the wood. This
does not necessarily mean that the chisel is
dull. More likely, a dull chisel will cause the
head to be difficult to lower.
10. When making rectangular mortises, we rec-
ommend you follow the sequence of cuts
shown in Figure 18.
7. An even pressure on the handle bar will pro-
vide the best mortising results. The rate of
penetration should be fast enough to avoid
burning the tip of the bit, but slow enough to
avoid stalling the motor.
1 3 2 5 4 6
8. Placing a piece of wood between your work-
piece and the mortiser’s table when through-
cutting will minimize tear-out.
9. When mortising thin stock, build up the
height of the workpiece enough for it to clear
the fence, so the hold down will function cor-
rectly.

SECTION 5: MAINTENANCE
General
Lubrication
The Model G3183 Hollow Chisel Mortiser
requires a minimum of maintenance. The opera-
tor should clear the machine of wood chips after
every use and periodically wipe the machine of
dust and grime. All of the bearings within the
machine are lubricated and sealed at the factory,
so lubrication by the operator is unnecessary. A
periodic application of light oil on the rack-and-
pinion gearing will insure smooth operation
between the head and column.
Make a habit of inspecting your Hollow Chisel
Mortiser each time you use it. Check for the fol-
lowing conditions and repair or replace when nec-
essary.
1. Loose mounting bolts.
2. Worn switch.
3. Worn or damaged cords and plugs.
4. Any other condition that could hamper the
safe operation of this machine.
