1) Inspect the carbon brushes. Most likely the brushes have been worn down and need to be replaced. When replacing your
carbon brushes, keep in mind that Cyclo carbon brushes have been made specifically for the Cyclo with a pre-cut contour on
the front edge of the carbon block to match our commutator, and a nylon plug has been placed in the rear of the carbon block
(in front of the spring) to interrupt the electrical flow when the carbon block wears down to this point. This prevents the load
spring from coming in contact with the commutator and shorting out the entire armature.
CAUTION: Be sure the power cord is disconnected. Unscrew the black brush cap found on each side of the motor housing. The
carbon brush and spring can then be easily withdrawn from the motor housing. Note how the contour in the carbon block matches
the contour of the motor commutator. The carbon brush must be reinserted in this same pattern to maximize electrical contact with
the commutator. If badly worn, down to the first printed letter, call Cyclo to order new brushes. Also replace if assembly has a weak
spring. Keep brushes clean and sliding freely in their guides.
2) Check the electrical supply for blown fuses and the plug and electrical receptacle for proper contact.
How to maintain your Cyclo polisher/sander:
1) Every eight hours of use, lubricate the upper motor bearing by placing 3 drops of 3-in-1 oil in the center of the copper bushing
found at the top of the motor housing.
2) Every eight hours of use, or as conditions warrant, blow out the motor housing with an air hose to clean out any accumulated
dust or dirt. If the tool is being used to clean carpets, be sure to blow out the motor housing after every use. If tool should get wet,
be sure to blow out the underside of the tool.
3) Never operate the polisher with chipped or otherwise damaged brush caps. Be sure the power cord is disconnected. Using a
screwdriver, remove the damaged brush cap and the carbon brush and spring, with a cotton Q-tip wipe the threads on the inside of
the brush holder clean of any foreign matter, replace the carbon brush and spring and screw on a new brush cap.
ANY OTHER SERVICING SHOULD BE PERFORMED BY AN AUTHORIZED CYCLO SERVICE CENTER OR THE TOOL

PLEASE KEEP IN MIND SERVICE REPAIRS CAN TAKE UP TO THREE WEEKS.
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, relubricate with Texaco Multifax #2 or equivalent.
CAUTION: The secret of the operation of your Cyclo polisher/sander 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 Cyclo service center for repair.
