SECTION 1: SAFETY For Your Own Safety Read Instruction Manual Before Operating This Equipment The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
Safety Instructions For Power Tools 9. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. Conductor size should be in accordance with the chart below. The amperage rating should be listed on the motor or tool nameplate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Your extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords if they become damaged.
Additional Safety Instructions For Shapers 1. NEVER ALLOW YOUR HANDS to come within 12 inches of the cutters. Never pass your hands directly over or in front of the cutter. 2. BLIND CUT WHENEVER POSSIBLE. This keeps the knives on the underside of the workpiece and provides a distance guard for the operator. 3. WHEN SHAPING CONTOURED WORK and using a rub collar, NEVER start out at a corner. See the “Rub Collar” instructions further on in the manual. 4. 5. 6. 7. 8.
SECTION 2: CIRCUIT REQUIREMENTS 220V Operation Grounding The Model G8621 Shaper is furnished with a 3450 R.P.M., 5 H.P., Single-Phase 220V motor, push-button ON/OFF magnetic starter switch, forward-reverse switch and a cord set. Under normal use, the motor draws approximately 25 amps @ 220V. We recommend a 30 amp circuit breaker. If frequent circuit failures occur when using the shaper, contact our service department.
Extension Cords Wiring We do not recommend the use of extension cords on 220V equipment. Arrange the placement of your equipment and the installed wiring to eliminate the need for extension cords. Should it be necessary to use an extension make sure the cord is rated Hard Service (grade S) or better. Refer to the chart in Section 1: Safety to determine the minimum gauge for the extension cord. The extension cord must also contain a ground wire and plug pin.

Clean Up The unpainted surfaces are coated with a waxy oil to protect them from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser such as Grizzly’s G7895 Degreaser. Avoid chlorinebased solvents as they may damage painted surfaces should they come in contact. Always follow the usage instructions on the product you choose to clean. Do not use gasoline or other petroleum-based solvents to clean with.
SECTION 4: ASSEMBLY Beginning Assembly Handwheel Most of your Model G8621 Shaper has been assembled at the factory, but some parts must be assembled or installed after delivery. We have organized the assembly process into steps. Please follow along in the order presented here. The handwheel, pre-installed at the factory, is made of cast iron. It is used to raise and lower the spindle to accommodate the height required by your cutter. Thread the crank handle onto the handwheel.
Spindle The Model G8621 comes with three interchangeable spindles like those in Figure 5. The spindles must be inserted correctly and remain stable in order to produce quality work. When installing and changing spindles, make sure the spindle seats snugly and that there is enough drawbar threaded into the bottom of the spindle to safely secure it in place. To install a spindle: 1. Align These Parts You should not have your machine connected to a power source at this time.
Handles 4. Install the round knobs shown in Figure 10 onto both ends of the bar. The guard adjuster is used to secure the guard to the table and to allow the guard to be loosened for adjustment. To assemble the guard adjuster: 1. Install the bar into the shaft guide as shown in Figure 8. 2. Line up the groove in the bar with the setscrew. Figure 10. Thread round knobs onto bar. Groove The wheel shown in Figure 11 fits on the adjustment shaft.
Guard Fence Assembly To mount the cutter guard to the table: To mount the fence brackets to the guard body: 1. Place the guard over the threaded holes on the table. 1. 2. Insert the shaft guide into the guard as shown in Figure 12, and thread the shaft guide clockwise to secure the guard to the table. Insert the adjustment shaft into the fence bracket as shown in Figure 14. Figure 14. Adjustment guide to fence bracket. 2. Figure 12. Inserting shaft guide into guard.
To install the wood facing: 1. 2. Secure the wooden fence pieces (as shown in Figure 16) with the 5⁄16''- 18 x 1'' Phillips® head screws, washers, and hex nuts provided. If using your own wood faces, make sure the countersunk holes in your fence material are deep enough to keep the entire screw head below the fence surface. Guard Cover To mount the guard cover: 1. Place the guard cover over the threaded holes on top of the guard body as shown in Figure 17. 2.
Hold-Downs Miter Assembly Hold-downs are used to hold the workpiece flat and snug against table as shown in Figure 18. To assemble the hold-downs: The miter gauge for the Model G8621 features a clamp and special fence. The miter gauge assembly can be mounted on either end of the table, depending on the type of desired cut or cutting direction. To mount the miter gauge and its fence: 1. Slide a hold-down plate into each of the cast iron hold-down brackets. 2.
4. With the provided washer, thread the ratchet handle through the miter gauge and into the table as shown in Figure 21. Figure 23. Installing the miter fence. 7. Slide the clamping unit onto the push shaft as shown in Figure 24. Figure 21. Installing the ratchet handle. 5. Insert the the miter gauge pointer shown in Figure 22, but do not tighten the nearby setscrew at this time. Figure 24. Installing the clamping unit. Figure 22. Installing the pointer. 6.
SECTION 5: ADJUSTMENTS Adjustment Setscrew Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back. Disconnect power to the machine when performing any adjustments or maintenance. Failure to do this may result in serious personal injury. Figure 25. Inspecting pulley alignment. 4. This process is easiest with the help of another person. Loosen the four bolts that attach the motor to the motor base.
V-Belt Tension Speed Changes You should be able to deflect the belt 1⁄4" with moderate finger pressure. This may seem tight compared to most other V-belts, but since the belt is small and runs fast, this amount of tension is necessary. The V-belt will slip if too loose, and will squeal or cause vibration if too tight. Adjust the tension if necessary. To adjust V-belt tension: The Model G8621 Shaper is equipped with a Vbelt drive system that controls the speeds. To change spindle speeds: 1.
Fence Adjustment Aligning The Fences The fence is a two-piece adjusting system. Each fence is independently adjustable to compensate for different cutting thicknesses and special shaping applications. Without any play, one turn of the knob moves the split fence approximately 5⁄64" (.078"). To adjust the fence: The following procedure ensures that the fence is parallel with itself and square with the table. 1.
Table Inserts Setting Miter Gauge The Model G8621 is supplied with two inserts which provide three possible opening diameters in the shaper table surface. Use the smallest opening that a particular cutter will allow. This offers more support for the workpiece and reduces the amount of chips that can fall into the machine. The correct spindle opening also allows any unused portion of the cutter to remain below the table surface—increasing operator protection.
Test Run Once assembly is complete and adjustments are done to your satisfaction, you are ready to start the machine. DO NOT have a cutter installed when you test run the shaper. Turn on the power supply at the main panel. Press the ON button. Make sure that your finger is poised on the OFF button, just in case there is a problem. The shaper should run smoothly with little or no vibration or rubbing noises.
SECTION 6: OPERATIONS Rotation Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back. Disconnect power to the machine when performing any adjustments or maintenance. Failure to do this may result in serious personal injury. Your shaper is equipped with a FORWARD/REVERSE switch as shown in Figure 30. In many instances, you will need to flip the cutter over and reverse cutter rotation. Whenever possible, mount the cutter so the board is milled on the bottom side.
Cutter Installation Table Lock Your shaper operates at speeds of 3600, 5100, 8000 and 10,000 R.P.M. 31⁄2" or larger cutters must be operated at the slowest speed. The sliding table works with the clamping miter gauge to allow you to secure your workpiece to the table and make the cut by sliding the table. This feature greatly increases operator safety because it keeps hands away from the cutterhead.
Spindle Height Straight Shaping To adjust the cutter height: 1. Loosen the spindle lock shown in Figure 33. 2. Move the spindle up or down with the handwheel until the desired position is obtained. 3. Lock the spindle into position. Read the entire manual before making any cuts with your shaper. Serious personal injury may result if safety or operational information is not understood or followed. The fence assembly is a two-piece, independently adjustable system.
4. Loosen the mounting screws on the fence faces and set the face ends to barely clear the cutter. This allows the maximum support possible for the workpiece while passing the cutter. Remember to tighten the wood facing before starting the shaper. 5. A test sample of the desired cut should be advanced about 8'' then stopped. 6. Once the shaper is turned off and the cutter has come to a complete stop, adjust the outfeed fence to support the new profiled edge. See Figure 35. 4.
Rub Collars 2. Rub collars are used when shaping curved or irregular workpieces, such as arched doors or round table tops. Rub collars also limit the depth of your cut. Above the cutter: When the rub collar is used above the cutter as seen in Figure 39, the cut cannot be seen. This offers some advantage: the stock is not affected by slight variations in thickness and accidental lifting will not damage the workpiece. If lifting occurs, simply correct the mistake by repeating the operation.
Pattern Work When using a pattern, the rub collar can be positioned either above, below or between cutters. The pattern is usually used when the entire edge is to be shaped or when many duplicate pieces are needed. Pattern work is particularly useful when rough cutting irregular or oversize pieces and then shaping the edge in a simple two-step operation. A pattern can be incorporated into a jig by way of adding toggle clamps, hand holds or other safety devices.
About starting fixtures: The purpose of the starting fixture is to support the workpiece during the beginning of the cut. The workpiece is typically placed in the starting position using the starting fixture for support, Then swung into the cutter while holding the workpiece firmly against the starting fixture. After the cut has been started, the work is swung away from the starting fixture and is supported only by the rub collar.
The miter fence can be adjusted by loosening the two bolts that hold it to the miter gauge and then sliding it in the desired direction. Shaper Accessories The support fence slides up and down the miter fence and can be locked to hold the back of the workpiece in place. There are many accessories that can be built or purchased to increase the safety of the operator. Many experienced shaper users regularly use proven shop-made fences and safety guards to augment their shaping operations.
SECTION 7: MAINTENANCE Lubrication Disconnect power to the machine when performing any adjustments or maintenance. Failure to do this may result in serious personal injury. General The only parts on this machine that require periodic lubrication are the ways where the cartridge slide rides on the elevation housing and where the worm gear and bushing are located. Use a light grease or anti-seizing compound on the ways and worm gear, and give the shaft mount a shot of light oil.
RESET Disconnect powerfrommachine beforeperforming any electrical service. Failure to do thiswill result ina shockhazard leading to injury ordeath. The motorstarting capacitor can still retain a chargeevenwiththe power disconnected. Turn the Reversing switchto theforward position. Thiswill discharge the capacitor. Failure to do so will leadtoasevere shockhazard.
