Slide cross bar toward outboard side as shown. 4. Loosen v-belt tension by loosening pinch bolt in motor support (Figure 38) and raise motor. Remove v-belt from pulleys. 5. Install new v-belt and tension the belt by using the weight of the motor only. Make sure the pulleys are aligned. Replace transfer rod and miter gear; tighten set screw on miter gear and replace protective cap. Tighten collar on transfer rod. 6. Install the outer half of the belt guard and tighten the six screws. Rotating Dru

If the breaker is tripped, turn the sander off and reset the circuit breaker by pressing the button (Figure 2, Item C). Be sure to turn the sander off before resetting the circuit breaker to avoid unintentionally starting the sander 9 This Page Intentionally Left Blank 10 Conveyor Belt Tracking Belt tracking adjustment may be necessary during the break-in period and normal operation to compensate for belt stretching. Abrasive belt tension must be properly adjusted before adjusting the tracking.

With a 1/8” wrench, adjust all four studs by tightening the lock nuts (Figure 28), then loosening them 1/8 to 1/4 turn. If the lock nuts are set too tight, height control will not operate easily. If the lock nuts are too loose, excessive deflection of the outboard end of the drum carriage will result. 2. Apply lubricant to front and rear areas of motor mount slide. 3. Push height adjustment handle (Figure 28) downward to set firmly on housing. Figure 27 Figure 28 18 4. Loosen set screws on colla

A good rule of thumb when sanding with grits finer than 80 is lower the drum so that it contacts with work piece but still can be rotated by hand. When using grits coarser than 80 grit, you can lower the drum slightly more. However, a combination of several variables will determine the proper depth of cut to use, including the following: • Abrasive type and grit size. • Width of the piece being processed. • Hardness of the piece. • Feed rate of stock. Establishing the Proper Drum Height To estab

The depth of cut is controlled by the height adjustment handwheel. It may take some experimentation to determine the proper depth of cut, given the variables of abrasive grit, type of wood, and feed rate. For best results, use scrap wood to practice sanding and to develop skill and familiarity with the machine before doing finish work. A combination of several variables will determine the proper depth of cut to use, including the following: 1. Abrasive type and grit size. 2. Width of the piece b

The oscillating movement of the belt is by design. Observe the belt's range of movement from its highest to lowest position. The edges of the belt should not have a tendency to move above or below the edges of the rollers. If adjustment is still necessary: 3. Insert the round shaft of the belt tracking tool (provided) into the micro adjust lock nut (A) and turn away from you to loosen. 4. Turn the micro adjusting screw (B) in 1/4 turn increments until the belt tracks evenly on the rollers when r

A. A temporary adapter (Fig. B) may be used to connect the plug to a two- prong receptacle (Fig. B) if a properly grounded outlet is not available. A temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter is not applicable in Canada. The green colored lug must be fastened to the cover plate screw. Important: The adapter illustrated in Fig. B is for use only if you already have a properly grounded two-prong receptacle. Do n

16). JET offers a wide variety of hoses, adapters and dust collectors. 2. Loosen the wing nut (B, Fig. 16) and pull the gate (C, Fig. 16) open to allow air suction to the sanding belt. Push the gate closed to shut off air suction. Tighten the wing nut. 3. Push the gate (D, Fig. 16) down to shut off air suction to the disc. Lift the gate to open the air suction to the disc. Lubrication All moving parts run on sealed ball bearings and require no lubrication. Optional Accessories Open Stand w/Belt

6. Tension belt by pushing handle to the right. 7. Reinstall the belt guards Note: Belts stretch with wear. You may have to adjust tracking with a new belt. Belt Tracking Adjustment 1. Disconnect the machine from the power source. 2. Push the belt by hand in the direction indicated on the belt cover. Observe the belt position on the rollers. Edge of belt should remain even with the edge of the rollers. 11 3. Insert the driver with the round shaft, supplied with the machine into the micro adjusti

9 10 Troubleshooting Trouble Possible Cause Solution Sander will not start 1. Sander unplugged from wall or motor 2. Fuse blown or circuit breaker tripped 3. Cord damaged 4. Starting capacitor bad 1. Check all plug connections 2. Replace fuse or reset circuit breaker 3. Replace cord 4. Replace starting capacitor Sanding drum does not come up to speed 1. Extension cord too light or too long 2. Low current 1. Replace with adequate size and length cord 2. Contact a qualified electrician Machi
