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]
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.
