Additional safety rules for bench grinders

• 

Always remove the plug from the mains socket before
making any adjustments or maintenance, including
changing the wheel.

• 

Always wear eye protection and check that the eye
shields on the grinder are properly adjusted.

• 

Always turn the grinder off when it is not in use and
never leave it unattended without first switching off
and removing the power plug. Never leave the grinder
until the grinding wheels have come to a complete stop.

• 

Make sure that any replacement wheel is rated at
3000RPM or higher.

• 

Do not let anyone under 18 years operate this tool.

• 

Rags, cloths, cord, string and the like should never be
left around the work area.

• 

If you are interrupted when operating the tool,
complete the process and switch off before looking up.

• 

Periodically check that all nuts, bolts and other fixings
are properly tightened.

• 

Do not use a wheel that has received a blow, especially
to the side of the wheel.

• 

Replace a cracked or suspect wheel.

• 

Always allow a new wheel to run for a few minutes at
full speed before using it. Stand to one side at start up.

• 

Check that the wheel rotates freely each time before
start up.

• 

Do not use the grinder unless all the guards are properly
fitted and secure.

• 

Check that the tool rests are properly adjusted before
commencing use.

• 

Do not overload the grinder. Allow the grinder to run at
full speed, or close to full speed during use.

• 

Never apply excessive pressure to the wheel. It might
shatter causing personal injury.

• 

Make sure that the wheel is not in contact with the
work when you start the grinder.

• 

When using the grinder, use safety equipment including
safety goggles or shield, ear protection, dust mask and
protective clothing including safety gloves.

Wear goggles
Wear ear protection
Wear a breathing mask

Unpacking

Due to modern mass production techniques, it is unlikely
that your GMC Power Tool is faulty or that a part is
missing. If you find anything wrong, do not operate the
tool until the parts have been replaced or the fault has
been rectified. Failure to do so could result in serious
personal injury.

Connecting to the power supply

The GMC Bench Grinders covered in this manual are
designed to operate from a standard household supply of
230-240V AC. Prior to plugging in the tool, check the
rating label on the rear of the grinder and ensure that it
states the tool’s operating voltage is 240V.
All the grinders are of Class 1 Category (earthed) and are
fitted with a 3-core cable and plug. Should the cable or
plug be damaged, the product should be serviced by an
authourised Service Centre to avoid a hazard.
