3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Fitting and adjusting the wheel guard
The wheel guard is a protective device to prevent
injury should the depressed center wheel shatter
during operation. Ensure that the guard is properly
fitted and fastened before commencing grinding
operation.
[Installing and adjusting the wheel guard] (Fig. 2)
Open the lever and insert the locating pin of wheel
guard, bringing it into line with the across flats of
packing ground.
Then, turn the wheel guard to a desired position
(for use).
Close the lever and fix it. If and when required,
carry out adjustments by tightening or loosening
the screw.
If the lever does not move smoothly, apply some
lubricating oil to the sliding section between the set
piece and the lever.
Fasten the wheel guard at the position where the
across flats of the wheel guard positioning pin and
packing ground are aligned (the position where the
wheel guard is inserted), but do not use it.
5. Ensure that the depressed center wheel to be utilized
is the correct type and free of cracks or surface
defects. Also ensure that the depressed center wheel
is properly mounted and the wheel nut is securely
tightened, refer to the section on "ASSEMBLING AND
DISASSEMBLING THE DEPRESSED CENTER WHEEL".
6. Conducting a trial run
Ensure that the abrasive products is correctly
mounted and tightened before use and run the tool
at no-load for 30 seconds in a safe position, stop
