SANDING CUTS AND SANDPAPER Initial Cut The purpose of the initial cut is to remove old finish and gross imperfections on the floor surface. A coarse abrasive should be used. If glazing, loading, or burning takes place immediately into an initial cut, select a coarser abrasive. If this should occur during an initial cut, the abrasive has dulled and must be replaced. Final Cuts The purpose of a finishing cut is to remove the scratches produced during the initial cut. Use a fine (60 - 80 grit) grain abrasive.
MACHINE SET-UP This sanding machine is designed to be operated with a remote vacuum dust collection sytem or with the included dust bag. Preparing Remote Vacuum Dust Collection Sytems To prepare the machine for remote vacuum dust collection systems that have a 2" hose end, follow this procedure: 1. Install 2" hose end directly over the exhaust tube. 2. The exhaust tube can be rotated for optimum convenience.
MACHINE SET-UP Cont. Preparing the Machine for Operation 1. Remove screw and abrasive retainer. Center abrasive on pad and secure with abrasive retainer and screw. (Figure 1) 2. Return machine to upright position and tilt machine back on casters until it comes to rest on the exhaust bracket. Machine will be in a reclined position. Do not allow machine to rest on pad especially after use, or compression set may take place within elastomer on pad. This will create a flat spot and bounce during use.
ADJUSTMENT PROCEDURES Leveling To level machine: Grasp caster adjusting screw "A" with an appropriate tool (pliers ect.). Using a similar tool, loosen locknut "B" with a counter clockwise motion. (Figure 4). A Condition - Pad creates ridges on both edges or a "hop" is experienced: Rotate both adjusting screws equal amounts clockwise. Tighten locknuts and test on a piece of plywood. Repeat procedure until condition is corrected. We recommend you not exceed 1/8" rotation for each attempt.
MAINTENANCE CAUTION: Maintenance and repairs performed by unauthorized personnel could result in damage or injury. Maintenance and repairs performed by unauthorized personnel will void your warranty. Failure to perform maintenance at recommended intervals may void warranty. Carbon Brushes Inspect all four brushes every 6 months or 250 hours. Access to the brushes is gained through the front and back motor vent plugs and under both motor covers (figure 5).
