3. Switching on the sander
The switch is of the quick-break trigger system.
When the trigger is pulled, the switch turns on; and
when it is released, the switch turns off.
When it is desired to keep the power on for a
prolonged period in continuous use, the stopper
can be used to keep the switch on even after the
trigger has been released. (First pull the trigger, and
then press the stopper.) To turn the switch off, first
pull the trigger again to disengage the stopper.
4. Precaution after use
Do not lay the sander down immediately after using
on a place where there are many shavings, much
dirt and dust until it has completely stopped
revolving.
CAUTION
When the disc sander is not in use, the power
source should be disconnected.
ATTACHMENT/REMOVAL OF SANDING DISC
(Fig. 2)
CAUTION: Be sure to switch power OFF and disconnect
the attachment plug from the receptacle to
avoid a serious accident.
(1) Attach washer, rubber pad and sanding disc on the
spindle, in that order.
(2) While pushing the lock lever with one hand, lock
the spindle by turning the rubber pad slowly with
the other hand.
Tighten the wheel washer by using the supplied
wrench.
⅜ Remove the sanding disc in the reverse order to
attachment.
CAUTION:
Confirm that the lock lever is disengaged by pushing
lock lever two or three times before switching the
disc sander on.
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. 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.
3. Inspecting the carbon brushes (Fig. 4)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brushes with new ones which have the same carbon
brush No. shown in the figure when they become
worn to or near the “wear limit”. In addition, always
keep carbon brushes clean and ensure that they
slide freely within the brush holders.
4. Replacing carbon brushes:
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
