PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
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.
[Adjusting the wheel guard, For G23SF2, G23U2 only]
By slightly loosening the setting screw, the wheel
guard can be turned and set at any desired angle for
maximum operational effectiveness.
Ensure that the setting screw is thoroughly tightened
after adjusting the wheel guard.
[Installing and adjusting the wheel guard, For G18SE3,
G18SG2, G23SE2, G23UB2 only]
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.
