7. TEST FOR SWITCH FUNCTION
(1) Make sure that the grip bar is screwed in firmly on the polisher body.
(2) Adjust the pressure of the compressor at 0.4MPa. Higher pressure makes higher
speed of polisher, which is not recommendable for this function test.
(3) Hold the grip bar ( see Figure 4, page 7 ) by one hand while pushing the switch
lock by a finger of another hand. Then, push the switch lever down to turn ON.
Release the finger from the switch lever to turn OFF while holding the grip bar
and the end case by the hands. The polisher is stopped automatically and
immediately. In addition, the switch lever is locked by the switch lock automatically
( see Figure 8, page 16 ).
8. TURNING OFF THE POLISHER
Before connecting the air hose to the compressor, ensure that the polisher is locked
at OFF position. Or, it would cause sudden start of the polisher. This is very
hazardous. When putting the polisher on floor or worktable, make sure to turn the
switch lever to OFF position ( see Figure 8, page 16 ).
9. TEST RUN
WARNING
･ CONNECT THE AIR HOSE SECURELY
Disconnection of the air hose during operation could result in hazardous whipping
of the air hose. Connect the air hose securely. In addition, when connecting the
air hose to the compressor, ensure the switch lever is locked at OFF position.
･ DO NOT TOUCH THE ROTATING PARTS
Do not access to the flexible polishing pad and the rotating parts while the
polisher is in running.
･ MAKE TEST RUN BEFORE POLISHING
When the polisher has reached the rotations for use after start, ensure no
inordinate noise and / or vibration. For the test run time, refer to TEST RUN TIME
in page 14. Polishing without test run could cause injuries.
･ FOLLOW THE RECOMMENDED SPEED OF POLISHER FOR THE TEST RUN
The recommended speed of polisher for the test run shall be smaller than the
maximum operating speed of flexible polishing pad, specified by its manufacturer.
･ DO NOT CARRY OUT TEST RUN OPERATION IN IMPROPER PLACE
Test run in improper place is hazardous. Secure stable scaffolding and hold the
operator’s body in stable position all the times.
･ STOP THE POLISHER IMMEDIATELY IN CASE OF UNINTENDED REACTION
SHOWN
Stop the polisher immediately if something inordinate condition is found during run.
