Preliminary polishing with sander using a finegrain
sanding disc.
Polishing with wool bonnet using polishing
compound and/or wax. Apply a small quantity of
compound and/or wax on material surface and polish
with the wool bonnet.
MOUNTING AND DISMOUNTING THE
SANDING DISC AND WOOL BONNET
1. For Sander operation
(1) After placing the sanding disc on the rubber pad,
thread the washer nut onto the spindle.
(2) While holding the spindle with the accessory wrench
(A), as shown in Fig. 2, turn the washer nut clockwise
with accessory wrench (B) to screw it onto the
spindle. Ensure that the washer nut is thoroughly
tightened by using both wrench (A) and (B).
(3) To remove the sanding disc, follow the above
procedures in reverse.
2. For Polisher operation
(1) Insert the washer nut through the rubber pad and
thread it onto the spindle.
(2) While holding the spindle with the accessory wrench
(A), as shown in Fig. 3, turn the washer nut clockwise
with accessory wrench (B) to screw it onto the
spindle. Ensure that the washer nut is thoroughly
tightened by using both wrench (A) and (B).
(3) As shown in Fig. 4, wrap the rubber pad with the
hood of the wool bonnet, and firmly secure it by
tightening and tying its draw string. Be sure the
excess string is firmly tucked inside the wool bonnet
to prevent it from flying out while polishing.
CAUTION
Improper fitting of the wool bonnet may cause
vibration.
(4) To remove the wool bonnet, follow the above
procedures in reverse.

MAINTENANCE AND INSPECTION

1. Inspecting the mounting screws:
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
2. Inspecting the carbon brushes (Fig. 5)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with a new one having the same carbon
brush No. shown in the figure when it becomes
worn to or near the "wear limit". In addition, always
keep carbon brushes clean and ensure that they
slide freely within the brush holders.
3. Replacing a carbon brush:
Disassemble the brush cap with a minus-head
screwdriver. The carbon brush can then be easily
removed.
4. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
