DANGER
Read, understand and observe all instructions in this
manual before using or operating the tool for which it is written
and supplied. Ensure that anyone who is to use the tool has
read and understood the instructions provided.
WARNING
• Always wear eye protection that complies with a recognized
standard (CSA or ANSI).
• Wear a mask or respirator when dust is generated.
• Keep bystanders out of the work area while operating the
tool.
• WARNING! Always ensure that the work area is clear of any
flammable materials, liquids or gasses, because the use of this
tool may create sparks.
• Tighten grinding wheel lock nuts, securing bolts and all clamps
and guards.
• During each start-up, stand to one side of the grinder and
switch it ‘On’. Let the grinder operate at full speed for approxi-
mately one minute so that any undetected flaws or cracks will
become apparent.
• Keep guards in place and working properly.
• Keep hands clear of grinding wheels.
• Never reach behind or beneath the grinding wheels.
• Unplug from power supply before adjusting or servicing. The
grinding wheels continue to rotate after the tool is switched off.
Always allow wheels to stop before adjusting or servicing.
• To avoid electric shock, DO NOT use in damp conditions or
expose to rain.
• When fitting a new grinding wheel, always check that the stat-
ed maximum RPM meets or exceeds that stated on the grinder.
Also check the new wheel for damage, such as flaws or cracks.
If the wheel appears satisfactory, fit it to the grinder.
• When a new grinding wheel has been fitted, stand to one side
of the grinder and switch it ‘On’. Let the grinder operate at full
speed for approximately one minute so that any undetected
flaws or cracks will become apparent.
• Use only accessories that are recommended by the manufac-
turer for your model.
• DO NOT attempt to cut anything with the grinding wheel.
• Grounded tools must be plugged into an outlet that has been
properly installed and grounded in accordance with all local
codes and ordinances. Never remove the grounding prong from
the plug or modify it in any way. Do not use adaptor plugs. If in
doubt as to whether the outlet is properly grounded, consult a
qualified electrician.
• Do not use the tool when tired or under the influence of drugs,
alcohol or medication.
• Do not wear loose clothing or jewellery. Keep hair tied back.
• Ensure the power switch is off prior to plugging in the tool.
• WARNING! Replace cracked grinding wheels immediately.
• Do not overtighten spindle nuts.
• Adjust tool rests whenever necessary to maintain a distance
of 1/8” (3.2 mm) from the grinding wheel.
• Service on these tools should only be performed by an autho-
rized, qualified technician.
