Safety Rules For All Tools


Unpacking

The Model G3183 Hollow Chisel Mortiser isshipped from the manufacturer in a carefullypacked carton. If you discover the machine isdamaged after you’ve signed for delivery, pleasecall Customer Service immediately for advice.

Save the containers and all packing materials forpossible inspection by the carrier or its agent.Otherwise filing a freight claim can be difficult.

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 HollowChisel Mortiser must be moved up or down aflight of stairs, be sure that the stairs are capableof supporting the combined weight of people andthe machine.

When you are completely satisfied with the con-dition of your shipment, you should inventory itsparts.

Piece Inventory

After all the parts have been removed from thecarton, you should have:

• Mortising Machine• Hydraulic Cylinder• Handle Bar• 5⁄8'' Chisel Bushing• 3⁄4'' Chisel Bushing• Chuck Key• Spindle Extension• Wood Table• Hold Down• Fence• 4 & 5mm Allen Wrenches• Flat Head Screw M6-1.0x20mm(2)

In the event that any non-proprietary parts aremissing (e.g. a nut or a washer...), we would beglad to replace them, or, for the sake of expedi-ency, replacements can be obtained at your localhardware store.


Clean up

The column and other unpainted parts of theModel 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 otherpetroleum based solvents because of theirextremely low flash points. Do not use chlorine-based solvents – if you happen to splash someonto a painted surface, you’ll ruin the finish.

WARNING!

Follow the safety rules listed below whenworking with solvents:

1. Read and follow all directions and warningson 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 soon).

4. DO NOT smoke while working with flamma-ble material.

5. Paper towels from the cleaning process areextremely combustible. Dispose of wastetowels so they do not create a fire hazard.

Site Considerations

1. Mounting: We recommend mounting yourHollow Chisel Mortiser to a bench. This willprevent the machine from tipping over and toallow for maximum leverage when mortising.

2. Working Clearances: Consider existing andanticipated needs, size of material to beprocessed through each machine, andspace for auxiliary stands, work tables orother machinery when establishing a loca-tion for your Hollow Chisel Mortiser.

3. Lighting and Outlets: Lighting should bebright enough to eliminate shadow and pre-vent eye strain. Electrical circuits should bededicated or large enough to handle amper-age requirements. Outlets should be locatednear each machine so power or extensioncords are clear of high-traffic areas. Observelocal electrical codes for proper installationof new lighting, outlets, or circuits.


Circuit Requirements

The motor supplied with the Model G3183 is a110V single-voltage motor, prewired for 110V.Under normal use, the motor draws approximate-ly 6 amps @ 110V. We recommend using a 15amp circuit breaker or a 15 amp slow blow fusefor 110V operation. This should be satisfactoryfor normal use, while preventing motor damagefrom high heat caused by overload. If frequentcircuit failures occur when using the HollowChisel Mortiser, contact our service departmentor your local electrical contractor. The HollowChisel Mortiser cannot be wired for 220V opera-tion.

This equipment must be grounded. Pleaseensure that the Hollow Chisel Mortiser is continu-ously grounded from the motor to the machineframe and then to a known ground. Verify thatany existing electrical outlet and circuit you intendto plug into is actually grounded. If it is not, it willbe necessary to run a separate 12 A.W.G. coppergrounding wire from the outlet to a known ground.Under no circumstances should the groundingpin from any three-pronged plug be removed.

Extension Cords: If used, extension cords mustbe rated Hard Service (grade S) or better.Conductor size must be 14 A.W.G. for cords up to50 feet in length. Your extension cord must alsocontain a ground wire and plug pin. Always repairor replace extension cords if they become dam-aged.

CAUTION: Be sure that your particular electricalconfiguration complies with local and state codes.The best way to ensure compliance is to checkwith your local municipality or licensed electri-cian.

Tools Required

The Model G3183 Hollow Chisel Mortiser hasbeen largely pre-assembled at the factory.However, some components must be assembledor installed after delivery. We have organized theassembly process into steps. Please follow alongin the order in which we have presented themhere. We also recommend that you spend sometime with the diagrams and parts lists to becomefamiliar with all the parts before you begin.

Tools Required: Common hand tools are all thatare necessary to assemble this machine.Specifically, you will need a screwdriver, 4mmand 5mm hex wrenches (provided) and a Phillipsscrewdriver.


SECTION 2: ASSEMBLY

Hydraulic Cylinder

To install the Hydraulic Cylinder:

1. Screw the handle bar into the adjustable gearon the right side of the mortising machine andraise the head to its highest position. Figure 1.

Figure 1.

Figure 2.

2. With the head fully extended above the mortis-er’s base, snap the hydraulic cylinder into thefittings located on the right side of the headand at the base of the column. Figure 2.


Table

To install the table:

1. Position the wood table on the base andsecure with two screws provided. Figure 3.

2. Secure the machine to a suitable work surfaceby fastening bolts through the holes providedin the mortiser’s base. This will eliminate thepossibility of the machine tipping while in use.

Figure 3.

Fence

To install the fence:

Insert the fence bar through the hole in the col-umn. Figure 4. It may be necessary to back outthe lock knob a few turns so the fence bar willpass through.

Figure 4.


Hold Down

To install the hold down:

Slide the hold down assembly over the verticalpost so the fingers extend forward of the fenceover the table. Leave the setscrew loose for now.Figure 5.

Figure 5.

Figure 6.

Figure 7.

Chisel Installation

1. Remove the chuck cover on the mortiser’shead by loosening the knobs at the front andside of the cover plate. Figure 6.

2. Mortise chisels have either a 5⁄8'' or 3⁄4'' mount-ing shank. Determine which chisel you wantto use and locate the proper chisel bushing.Remove the brass screw located on the front,bottom of the headstock. Figure 7.

Figure 8.

Figure 9.


5. Feed the bit into the chuck until the tip of thebit extends between 1⁄16'' and 3⁄16'' below thetip of the chisel edge. Once you have prop-erly aligned the bit and chisel, tighten thechuck with the chuck key provided in thepackage.

NOTE: If the bit extends beyond the maximum3⁄16'' below the chisel, even when fully engaged inthe chuck, it will be necessary to shorten theshank of the bit to achieve proper clearance.

4. Insert the bit into the chisel, then insert boththrough the bottom of the bushing. Loosenthe brass screw, if necessary, to allow thechisel and bit to pass by. Push the chisel asfar as it will go into the head assembly.Tighten the brass screw to hold the chisel inposition. Figure 9.

3. Place the bushing in the opening directlyunder the chuck. Align the hole on the sideof the bushing with the threaded hole in thefront of the headstock. Once in place, threadin the brass screw. Figure 8.


Figure 10.

Chuck Extender

The use of the chuck extender is only necessaryif the chisel is too short to reach the chuck. Theextender will lower the chuck approximately 1''.To install the extender:

1. Remove the chuck cover on the mortiser’shead by loosening the knobs at the front andside of the cover plate.

2. Hold the motor shaft in place with a 10mmwrench. Insert a phillips screwdriver into thechuck key hole and unscrew the chuck in aclockwise direction. Figure 10.

3. Thread the chuck extender onto the end ofthe motor shaft then thread the chuck on.

4. Lightly tighten the chuck onto the extender.


Headstock

SECTION 3: ADJUSTMENTS

The handle bar on the Model G3183 HollowChisel Mortiser raises and lowers the head byrack-and-pinion gearing. The handle bar can beadjusted for comfort and maximum leverage byloosening the nut at the end of the pinion shaftjust enough for the right and left adjustable gearsto disengage. Figure 11.

Figure 11.

Fence

The fence can be moved forward and backwardto 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

The hold down is designed to prevent the work-piece from lifting when the chisel is retracted. Thehold down should be adjusted so it just comes incontact with the workpiece – allowing it to moveside-to-side, but not up and down. To adjust thehold down, loosen the setscrew at the verticalpost, move the hold down to the desired heightand tighten the setscrew. The hold down can beflipped upside down to accommodate largerstock. Figure 13.

NOTE: Ensure that the hold down is centered soits fingers do not interfere with chisel movement.The vertical post is flattened on one side. Positionthe hold down so the setscrew meets the flat sur-face.

Figure 13.

Depth Stop

The depth stop rod allows you to control thedepth of your mortise cuts by limiting the distancethe 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 theleft side of the head and drop the depth stop roduntil it touches the base.Tighten the setscrew.Figure 14.

Figure 14.


Head Adjustment

Proper adjustment of the head and column isnecessary to ensure that mortiser travel issmooth and precise. Two bolts located at theback of the head control the tightness of the headand column. If movement of the head becomessloppy, tighten the bolts until the travel is smoothand solid. Should the head movement becometoo difficult, loosen the bolts until movement issatisfactory. Figure 15.

Two setscrews mounted just forward of the boltsensure that side-to-side movement is minimal. Ifhead displays excess wiggle from side-to-side,loosen the locknuts and tighten the setscrewsuntil movement is eliminated. Tighten the lock-nuts. Figure 16.

CautionAlways wear ANSI-approved safetyglasses or goggles when operatingequipment. Do not allow visitors intoyour workshop when testing or oper-ating equipment.

SECTION 4: OPERATIONS

Safety Rules • Before machine inspection, maintenance orchanging accessories: Turn off switch, unplugpower cord and wait for all moving parts tostop.

• Keep hands away from the chisel and bitwhile this tool is being operated.

• Always have the chisel opening facing awayfrom the operator or the fence.

• The bit should reach full speed before begin-ning a cut.

• Always feed chisel evenly and smoothly.

• Do not touch the chisel during the mortisingoperation.

• Never leave the mortiser running unattended.

This sums up our review of safety guidelines.Remember that every shop has its own specifichazards. Be sure, above all else, to use goodcommon sense and reasonable caution eachtime you start this Hollow Chisel Mortiser, or anywoodworking machinery. Proper safety stan-dards rarely take any more time or energy whenfollowed religiously. Develop a habit of safety.

Earlier in this manual we covered general shopand machine safety rules. This section willaddress safety rules specific to your mortiser.

• Be sure to observe all electrical requirementssuch as fuse sizing, wire sizing, machinegrounding and any other electrical considera-tion.

• Always wear eye protection while operatingthis mortiser. Also use a respirator to avoidbreathing dust. All safety equipment must beANSI approved.

• Always be aware of the condition of the woodyou are mortising. Pay particular attention toknots, splits, and other potentially dangerousareas.

• Never attempt to operate the mortiser withbits or chisels that are dull or damaged. Theywill 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.


Once the assembly is complete and the adjust-ments are done to your satisfaction, you areready to test the machine.

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 casethere’s a problem. The Hollow Chisel Mortisershould run smoothly, with little or no vibration orrubbing noises. Strange or unnatural noisesshould be investigated and corrected beforeoperating the machine further.

WARNING: DO NOT attempt to investigate oradjust the machine while it is running. Wait untilthe machine is turned off, unplugged and allworking parts have come to a rest before you doanything!

If noises occur that cannot be found by visualinspection, feel free to contact our service depart-ment for help.

Test Run

1. Place the workpiece on the table and adjustso chisel is aligned correctly for desiredmortise cut.

2. Secure the fence so the workpiece is firmlysupported.

3. Position the hold down as described earlier,so upward movement of the workpiece iseliminated.

4. Turn power on.

5. Lower the head by pulling the handle bardown with your right hand, while supportingthe workpiece with your left hand. NOTE:Be extremely careful to avoid the chisel withyour left hand. It is very sharp, and frictionwill make it hot enough to cause burns toyour skin. Figure 17.

Mortising

Figure 17.


Figure 18.

1 23 45 6

6. The chisel and bit will cause some smokingas it contacts the workpiece. This is causedby friction heating resins in the wood. Thisdoes not necessarily mean that the chisel isdull. More likely, a dull chisel will cause thehead to be difficult to lower.

7. An even pressure on the handle bar will pro-vide the best mortising results. The rate ofpenetration should be fast enough to avoidburning the tip of the bit, but slow enough toavoid stalling the motor.

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 theheight of the workpiece enough for it to clearthe fence, so the hold down will function cor-rectly.

10. When making rectangular mortises, we rec-ommend you follow the sequence of cutsshown in Figure 18.


SECTION 5: MAINTENANCE

Lubrication

The Model G3183 Hollow Chisel Mortiserrequires a minimum of maintenance. The opera-tor should clear the machine of wood chips afterevery use and periodically wipe the machine ofdust and grime. All of the bearings within themachine are lubricated and sealed at the factory,so lubrication by the operator is unnecessary. Aperiodic application of light oil on the rack-and-pinion gearing will insure smooth operationbetween the head and column.

Make a habit of inspecting your Hollow ChiselMortiser 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 thesafe operation of this machine.
