Working Hints For Your Bench Grinder
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.
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.
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.
