SECTION 1: INTRODUCTION Grizzly Imports, Inc. is proud to offer the Model G3183 Hollow Chisel Mortiser. This Model G3183 is a part of Grizzly’s growing family of fine woodworking machinery. When used according to the guidelines stated in this manual, you can expect years of trouble-free, enjoyable operation. The Model G3183 is intended for home and medium-duty professional use. This Model G3183 features a 3450 R.P.M., 1⁄2 H.P. capacitor-start motor, mechanical ON/OFF switch and an adjustable depth stop.
Safety Rules For All Tools 1. KNOW YOUR POWER TOOL. Read the owner’s manual carefully. Learn the tool’s applications and limitations, as well as its particular hazards. 2. KEEP ALL GUARDS IN PLACE and in working order. 3. GROUND ALL TOOLS. If an adapter is used to accommodate a two-prong receptacle, the adapter plug must be attached to a known ground. Never remove the grounding prong. 4. 5. 6. 7. REMOVE ADJUSTING KEYS AND WRENCHES.
Unpacking Piece Inventory 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.
Clean up The column and other unpainted parts of the Model G3183 are coated with a waxy oil that protects them from corrosion during shipment. Remove the protective coating with mineral spirits and paper towels. Do not use gasoline or other petroleum based solvents because of their extremely low flash points. Do not use chlorinebased solvents – if you happen to splash some onto a painted surface, you’ll ruin the finish. Site Considerations 1.
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 approximately 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.
SECTION 2: ASSEMBLY Hydraulic Cylinder 2. With the head fully extended above the mortiser’s base, snap the hydraulic cylinder into the fittings located on the right side of the head and at the base of the column. Figure 2. To install the Hydraulic Cylinder: 1. Screw the handle bar into the adjustable gear on the right side of the mortising machine and raise the head to its highest position. Figure 1. Figure 2. Figure 1.
Table Fence To install the table: To install the fence: 1. Position the wood table on the base and secure with two screws provided. Figure 3. Insert the fence bar through the hole in the column. Figure 4. It may be necessary to back out the lock knob a few turns so the fence bar will pass through. Figure 3. 2. Secure the machine to a suitable work surface by fastening bolts through the holes provided in the mortiser’s base. This will eliminate the possibility of the machine tipping while in use.
Hold Down To install the hold down: Slide the hold down assembly over the vertical post so the fingers extend forward of the fence over the table. Leave the setscrew loose for now. Figure 5. Chisel Installation 1. Remove the chuck cover on the mortiser’s head by loosening the knobs at the front and side of the cover plate. Figure 6. Figure 6. Figure 5. 2. Mortise chisels have either a 5⁄8'' or 3⁄4'' mounting shank. Determine which chisel you want to use and locate the proper chisel bushing.
3. Place the bushing in the opening directly under the chuck. Align the hole on the side of the bushing with the threaded hole in the front of the headstock. Once in place, thread in the brass screw. Figure 8. Figure 9. 5. Figure 8. 4. -10- 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.
Chuck Extender The use of the chuck extender is only necessary if the chisel is too short to reach the chuck. The extender will lower the chuck approximately 1''. To install the extender: 1. Remove the chuck cover on the mortiser’s head by loosening the knobs at the front and side of the cover plate. 2. Hold the motor shaft in place with a 10mm wrench. Insert a phillips screwdriver into the chuck key hole and unscrew the chuck in a clockwise direction. Figure 10. G3183 Hollow Chisel Mortiser Figure 10.
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.
Hold Down Depth Stop The hold down is designed to prevent the workpiece 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.
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. Two setscrews mounted just forward of the bolts ensure that side-to-side movement is minimal.
SECTION 4: OPERATIONS Safety Rules • Earlier in this manual we covered general shop and machine safety rules. This section will address safety rules specific to your mortiser. Before machine inspection, maintenance or changing accessories: Turn off switch, unplug power cord and wait for all moving parts to stop. • Keep hands away from the chisel and bit while this tool is being operated. • Always have the chisel opening facing away from the operator or the fence.
Test Run Mortising Once the assembly is complete and the adjustments 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 finger 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.
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. 7. An even pressure on the handle bar will provide 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. 8.
SECTION 5: MAINTENANCE General Lubrication Make a habit of inspecting your Hollow Chisel Mortiser each time you use it. Check for the following conditions and repair or replace when necessary. The Model G3183 Hollow Chisel Mortiser requires a minimum of maintenance. The operator should clear the machine of wood chips after every use and periodically wipe the machine of dust and grime.
