OPERATION
INSTRUTIONS
NOTE: Before using the tool, read the
instruction book carefully.
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. (See Fig.A)
The next step is to adjust the eye shields/spark arresters. To
do this move the eye shields/spark arresters so as to obtain
a gap as small as possible between the arrester and the
grinder wheel, not greater than 2mm, the screw must now
be fully tightened, See Fig.B. The gap must be maintained
as the wheel wears.
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 Fig.C. 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 knobs on each of the
rests, set the correct gap and fully tighten, See Fig.D. The
gap must be maintained as the wheel wears.
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.
4. CHANGING GRINDING WHEELS (See Fig.E)
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).
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.
WARNING: OVERTIGHTENING CAN
CRACK A GRINDING WHEEL
MAINTENANCE
Remove the plug from the socket before
carrying out any adjustment, servicing or
maintenance.
If the supply cord is damaged, it shall be replaced by the
manufacturer or its service agent or similarly qualified
person in order to avoid a hazard.
TROUBLESHOOTING
Although your new bench grinder is really very simple to
operate, if you do experience problems, check the following:
1. GRINDER WILL NOT START
Check that there is "mains" at the socket; test with an
electrical screwdriver or another electrical appliance;
check the connections in the plug; correct and tighten poor
connections; check the fuse; if suspect replace with correct
rating.
2. WHEEL WOBBLES OR VIBRATES
Check that the lock-nut is tight. Check that the wheel
is correctly located on the shaft and locating washer.
If excessive pressure has been used or the wheel has
"caught", it may be damaged causing it to vibrate. If there
is any evidence that the wheel is damaged, do not use,
remove it and replace with a new wheel. Dispose of old
wheels sensibly.
3. WHEEL LEAVES ROUGH FINISH
Too much pressure on the wheel can cause a poor surface
finish. If working with aluminium or similar soft alloy,
the wheel will soon become clogged and will not grind
effectively.
There are no other users serviceable parts in your bench
grinder.
HANDY HINTS
Your bench grinder is useful for sharpening tools, e.g. drills,
chisels; refacing tools, e.g. removing burrs from tool edges;
removing material, however this is not a heavy duty tool and
is designed primarily for light home and hobby use.
The two different types of wheel will allow the grinder to
meet various needs. Typically, use the coarse grinding
wheel for rough cutting, i.e. removing a larger amount of
material.
Use the medium wheel for finishing to leave a smoother
surface.
If the grinder is used on soft metals such as aluminium, the
wheel will soon clog and will have to be changed.
At all times, let the grinder do the work, do not force it or
apply excessive pressure to the wheel/cutter.
Try to use the tool rest for supporting and guiding the
workpiece. Do not grind using the side cheeks of the
grinding wheel as undue pressure on the side of the wheel
could cause the wheel to shatter.
