ASSEMBLY Always ensure the sander is unplugged prior to attempting any assembly, installation or changing of parts and accessories. ASSEMBLE THE FRAME TO THE BASE 1. Place the Base (Part #5) on a bench and locate the two elongated holes that will be used to secure the sanding Frame (#64) to the base. 2. Remove the plastic Belt Cover (#74) from the frame, by unscrewing the two Knobs (#75). This will allow you to see the two threaded holes in the frame for alignment with the base’s holes. FIG. 1. 3.
ASSEMBLY INSTALL THE INSIDE BELT GUARD 12. The inside metal Safety Plate (#39) fits between the motor and the Belt Guard (#37). 13. Position the metal plate inside of the belt guard. The bent tabs will keep it in place, then secure it with the long M4 Phillips head Screw (#36) and hex Nut (#40). FIG. 6. FIG. 6 INSTALL THE SANDING DISC 14. Make sure the metal Sanding Disc Plate (#33) is clean of foreign material. NOTE: This disc only takes PSA (pressure sensitive adhesive) sanding abrasives. 15.
ASSEMBLY CURVED KEYWAY INSTALL THE DISC SANDING TABLE 21. An adjustable Handle and Washer (#25, 26) are supplied to hold the Sanding Disc Table (#22) in position on the sanding base. 22. Line the disc sanding table’s slotted right end with the curved keyway in the sanding disc base. Position it in the keyway so that the handle can be installed, fastening the parts together. FIG. 10.
ASSEMBLY INSTALL THE TOOL HOLDERS WRENCH HOLDER Holders (#88, 90) for convenient storage of the Miter Gauge and Wrenches are supplied. Mount them onto the back of the Belt Frame Casting (#64) with the Phillips Screws supplied (#89). MITER GAUGE HOLDER MOUNTING THE SANDER TO A WORKBENCH OR STAND Lag Bolt CAUTION: If during operation there is any tendency for the sander to tip over, slide or walk on the supporting surface, the sander should be properly mounted to a workbench or stand. 1.
OPERATION When sanding, always position your work on the downward, rotating side (left side) of the sanding disc. FIG. 16. The sanding action will then force the wood down, safely towards the table, where it can be controlled. Sanding on the right, upward rotating side of the disc is dangerous, as your work cannot be controlled and ‘kick-back’ may occur - the wood being forced up and out of your hands.
OPERATION Always ensure the sander is unplugged prior to attempting any assembly, installation or changing of parts and accessories. BELT SANDING 1. Depending on what type of sanding that you will be doing, set the Sanding Belt Table to the proper angle from 45° to 90° with a protractor, or other angle measuring tool or pre-cut sample. 2. Once the table has been set for the correct sanding angle, and all fasteners are secure, the machine can be plugged in for operation. 3.
OPERATION Always ensure the sander is unplugged prior to attempting any assembly, installation or changing of parts and accessories. SANDING BELT DIRECTION CHANGING THE SANDING BELT 1. Remove the plastic Cover (#74) from the frame by unscrewing the two knobs (#75). 2. Tilt the sanding belt table forward to 45° so that there is ample space between the platen and rear of the table to remove the belt. 3. Press down on the tracking knob (FIG.
ADJUSTMENTS DISC TABLE ADJUSTMENTS Ensure sander is disconnected from the power supply prior to commencing work. 1. To check the trueness of the 90º angle of the disc sanding table, place a square or other measuring device on the table with the other end against the sanding disc. FIG. 24. 2. Loosen the disc table adjustment Handle (#25), and adjust table angle to 90º. 3. Re-tighten the disc table adjustment handle. 4. Adjust the Angle Scale Pointer (#16) to 0°. 5.
ADJUSTMENTS V-BELT TENSION ADJUSTMENTS Ensure sander is disconnected from the power supply prior to commencing work. Should the rotation of the sanding belt or disc slow down or stall, the cause may be that the V-belt is slipping on the two pulleys. This may be because the motor or frame have become loose from the base, or that the V-belt has stretched out due to the machine being used. In either case, re-adjustment of the V-belt is needed. FIG. 28 1.
