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.
■
Do not use sanding belt larger than needed.
■
Make sure the sanding belt is installed in the correct
direction.
■
Do not operate the product without a properly tracked
and fitted belt. An incorrectly tracked belt may come off
the product and cause personal injury or damage to the
product.
■
Change the sanding belt frequently to maintain the
product's ability to effectively remove material.
■
Do not use a sanding belt which is damaged, torn, or
loose. Use only a sanding belt of the correct size.
■
Choose a belt of the correct size and appropriate
roughness for the task. Use belts with a lower grit
number for removing more material, higher grit number
for removing less material and for a finer finish. Replace
the belt if it becomes damaged, clogged with debris or
is worn.
■
Do not force the product. Use the correct product for
your application. The correct product will do the job
better and safer at the rate for which it was designed.
■
Always hold the workpiece firmly when grinding or
sanding.
■
To minimise the risk of tipping machine, always support
long workpieces.
■
Never grind or sand more than one workpiece at a time.
Do not stack more than one workpiece on the work rest
at a time.
■
Do not reach into the product while it is running.
■
Avoid awkward operations and hand positions where
a sudden slip could cause your hand to move into the
grinding wheel or sanding belt.
■
Avoid kickback by grinding or sanding in accordance
with directional arrows.
■
Never stand or have any part of your body in line with
the path of the workpiece.
■
Chips and splinters must not be removed while the
product is running.
■
The dust produced when using the product may be
harmful to health. Do not inhale the dust. Use a dust
absorption system and wear a suitable dust protection
mask. Remove deposited dust thoroughly, e.g. with a
vacuum cleaner.
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.
■
Do not use damaged grinding wheels, do not use wheels
that are chipped, cracked or otherwise defective.
■
Ensure that the abrasive grinding wheel is correctly
fitted and tightened before use.
■
Machine should never be connected to power supply
when you are installing or removing grinding wheels.
■
Store your spare grinding wheel carefully.
●
Keep the wheel inside the original package if
possible.
●
Store the wheel in a dry area at room temperature.
●
Wheels may be stored vertically on a shelf.
●
Do not allow the wheels to fall or suffer any impact.

2. Nominal dimensions of grinding wheel, in particular the
diameter of the bore.
3. Abrasive type, grain size, grade or hardness, type of
bond and use of reinforcement.
4. Maximum operation speed in metres per second.
5. Maximum permissible speed of rotation in 1/min .
6. For declaration of conformity, the abrasive products
shall be marked with EN 12413.
