Additional Maintenance and Service Information
Lubrication:
This tool was properly lubricated at the factory and is ready to use. The gears should be inspected after approximately 400 hours of use. If necessary, re-lubricate
with Texaco Multifax #2 or equivalent.
Timing:
The secret of the operation of your Orbot Micro lies in the fact that the two heads are timed exactly 1/2 turn apart. This is necessary for the balanced operation
of the tool. If the machine is disassembled, use the following procedures to insure proper timing of the heads.
1) Turn the tools main case upside down, with the motor case, cover plate, and idler gear removed. Move the two heads together as close as possible. Then, put a heavy
rubber band around the side of the two heads to keep them together.
2) Turn the tool right side up and carefully replace the idler gear without moving the drive gears. Now, pack the recessed well in back of the idler gear with lubricant. Also,
lubricate the metal shafts in the center of each gear.
3) Reassemble the cover plate and motor case and remove the rubber band.
Bearings:
The bearings in the counterweights will loosen slightly with continued long use. This actually improves the action of the tool by allowing the heads to tilt slightly
and follow a contoured surface better. These bearings should not be considered defective until they become objectionably noisy at which time the entire polisher
should be sent to an authorized Orbot Micro service center for repair.
Heads:
The head assemblies (0.75" thick black neoprene discs) and ProGuard Orbital Backing Plates of the polisher will wear out gradually with use. The head
assemblies (60-055) should be replaced when they no longer hold the rubber pad holder or polishing bonnets firmly in position. Simply turn the polisher upside
down (so the twin heads are facing up), and rest the polisher on a counter or on your lap. Slide the 5/8" flat wrench between the head and the counterweight.
With the wrench in one hand and the head in the other, twist the head counterclockwise until the threaded shaft is completely clear of the nut. Oil the nut threads
slightly, and reverse the above procedure to attach new heads or other attachment system. Be sure to screw the head of brush straight into the counterweight
nut. Do not cross-thread. If the shaft seems to be screwing into the nut with difficulty, back it out and start over again. Be sure to tighten the heads or brushes
snugly into the nut.
