7 OPERATION
7.1 Assembly instructions
Before use, the eye shields/spark arresters must be fitted to the grinder. Remove both eye
shields from packaging, position the shields over the two mounting brackets above the
grinding wheels with the flanges of the spark arrester facing away from you, fix with the screw
and washer provided. At this stage do not fully Tighten.
7.2 Work rest adjustment
Take the work rest out of the package, fix on the grinder with the knob and washer provided
as shown in dia3. The gap between the rests and the wheels should be checked before use.
Measure the gap between the grinding wheel and the rests; this should be as small as
possible not greater than 2 mm, if not, loosen the two knobs on each of the rests, set the
correct gap and fully tighten. The gap must be maintained as the wheel wears.
7.3 Operating
Make sure grinder is securely mounted; mounting holes are provided in the base of the grinder
for this purpose, but the screws are not provided. Plug in the mains supply and push the on/off
switch right to the on position. Switch off and unplug the grinder when not in use.
7.4 Changing grinding wheels (dia5)
To change the grinding wheels, first unplug from mains supply then remove the eye shield
brackets, then undo and remove the three screws holding the wheel guard covers in place.
Remove the cover. Undo and remove the two wheels retaining nuts (a). You may have to hold
the wheel and give the spanner a firm tap with a soft headed hammer to release the nut, take
off the large domed washer(b), paper washer(c) and remove the wheels(d).
8 OPERATION AND TROUBLESHOOTING
NOTE: The nut on the right side of the grinder has a standard right hand thread (turn counter-
clockwise to loosen). The one on the left side has a left hand thread (turn clockwise to loosen).
Replace in same order, making sure both domed washers face correct direction, check the
paper washer(c and e), if damaged replace with new paper washer. Hold the wheel and
tighten the nut firmly but do not over-tighten.
Note: only replace flanges with original items, these can be supplied through a authorized
dealer.
Waring: overtightening can crack a grinding wheel.
