Mount the grinder sander firmly to the workbench,
grinding stand or other rigid frame before operation. An
unsecured grinder sander is unstable and may move
during operation. This may result in damage or injury.
Provide adequate general or localized lighting to
prevent stroboscopic effect and hazards.
Prior to operation, inspect the components and any
accessories of the grinder sander to ensure there are
no conditions that may affect proper operation. Tighten
grinding wheel lock nuts, securing bolts and all clamps
and guards.
Prior to each start up, inspect the grinding wheel for
damage. Do not use damaged or misshapen wheels.
Replace any damaged grinding wheel according to the
instructions.
Check that the wheel rotates freely prior to each start
up. With the grinder sander unplugged and the switch
turned to OFF, carefully spin the wheel by hand. The
wheel should not contact any components of the
bench grinder, and there should be no binding or other
conditions that may affect proper operation.
During each start-up, stand to one side of the grinder
sander and switch it ON. Let the grinder sander operate
at full speed for one minute so that any undetected
flaws or cracks of the wheel will become apparent.
Do not contact the wheel with the work piece until the
grinder sander has reached full speed.
Keep hands and body parts clear of grinding wheels.
Contacting the rotating wheel may cause injury.
Always use guards and eye shields. Keep all guards
in place and in working order. Operating the grinder
sander without guards or with damaged guards may
result in injury.
Avoid burns. Grinding may cause items and the grinding
wheel to become hot. Do not touch the grinding wheel
or items that may be hot.
Do not use the grinder sander to work on small items or
items which cannot be held properly. The item may be
thrown and result in injury.
Never grind on the side of the wheel. The wheel will
shatter. Grind on the face of the wheel only.
Never leave a running tool unattended. Turn the power
switch to OFF. The grinding wheels continue to rotate
after the tool is switched off. Do not leave the tool until
it has come to a complete stop.
Never reach behind or beneath the grinding wheels.
Use ear protection, such as plugs or muffs, during
extended periods of operation.
Remove the plug before carrying out any adjustment,
servicing or maintenance. The power cord must remain
unplugged whenever you are maintaining your grinder
sander.
Adjust tool rests whenever necessary to keep the
distance between the work rests and the grinding
wheels as small as possible. This distance should
be less than or equal to 2 mm. As the diameter of
2
the grinding wheel decreases with use, maintain the
maximum tool rest distance by adjusting it.
Adjust spark arrestors whenever necessary to keep
the distance between the spark arrestors and the
grinding wheels as small as possible. This distance
should be less than or equal to 2 mm. As the diameter
of the grinding wheel decreases with use, maintain the
maximum spark arrestor distance by adjusting it.
If the work rest becomes worn or damaged, replace
it with an identical replacement from the authorised
service centre.
When fitting a new grinding wheel, always check that
the stated maximum RPM meets or exceeds that stated
on the grinder sander. Ensure the wheel diameter and
arbor size meet that stated on the specifications. Also
check the new wheel for damage, such as flaws or
cracks.
GRINDING WHEEL SAFETY INSTRUCTIONS
WARNING
To reduce the risk of injury, user must read and comply
with instructions, warnings and operator's manual before
starting to use this grinding wheel. Failure to heed these
warnings can result in wheel breakage and serious
personal injury. Save these instructions.
The use of any wheel other than the one recommended
in the machine instruction manual may present a risk of
personal injury. Use only grinding wheels which have
marked speed equal or greater to that marked on the
machine.
Never use grinding wheel that is too thick to allow outer
flange to engage with the flats on the spindle. Larger
wheels will come in contact with the wheel guards,
while thicker wheels will prevent the bolt from securing
the wheel on the spindle. Either of these situations
could result in a serious accident and can cause serious
personal injury.
This wheel is for grinding and shaping metal. Do not
attempt to do cut-off operation.
This grinding wheel is only suitable for dry grinding.
