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.
 Before using the wet wheel fill the trough with clean water to a level lust below the top
edge of the trough. The wet wheel will cut more than the dry wheel but .because it is
running more slowly and it is cooled by water. It will produce a fine edge without any risk
of burning.
Note: only replace flanges with original items, these can be supplied through a authorized
dealer.
Waring: overtightening can crack a grinding wheel.
8.1 Troubleshooting
Although your new bench grinder is really very simple to operate, if you do experience
problems, check
the following:
8.1.1 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.
8.1.2 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.
8.1.3 Wheel leaves rough finish.
Too much pressure on the wheel can cause a poor surface finish. If working with aluminum or
similar soft alloy, the wheel will soon become clogged and will not grind effectively.
There are no other user serviceable parts in your bench grinder.
8.2 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.
