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 be

shattered during operation. Ensure that the wheel

guard is properly fitted and fastened before

commencing grinding operation.

⅜ Tighten M5 screw to secure the wheel guard while

the lever is in closed position.

⅜ Perform the adjustment of the wheel guard while

the lever is released. (Loosen M5 screw and readjust

if the wheel guard does not rotate smoothly.)

⅜ After adjustment, if grinder operation is required,

perform the operation only after setting the lever

in closed position.

⅜ Lubricate the sliding section of the set piece (B) and

the lever if the lever does not move smoothly.

to adapt large hole abrasive wheels.

For tools intended to be fitted with threaded hole

wheel, ensure that the thread in the wheel is long

enough to accept the spindle length.
