Additional Safety Recommendations for
the use of Superabrasives on Handheld
Machines
• Superabrasives are generally inflexible and could shatter, so must be handled with the
utmost care. Damaged or improperly mounted superabrasives are dangerous and can
cause SEVERE injury to the user and other people in the vicinity
• Types of superabrasive wheels include diamond cutting discs, welded metal discs,
CBN discs etc. Choose your superabrasive tool carefully, taking into consideration the
workpiece material, the machine dimensions and capabilities. Make sure the machine
does not exceed the maximum operating speed of the superabrasive disc
• NEVER use superabrasive cutting discs for side grinding, as this might lead to the disc
shattering
• Superabrasive wheels have to be carefully inspected and tested before mounting. Metal
wheels should be subjected to a sound test: hold the wheel on a mandrel or with a
finger inserted through the bore, then tap it with a non-metallic object at several points
and listen each time to the sound produced. An intact wheel will produce a clear ‘bell
like’ metallic sound. Damaged wheels will give a dull, chattering sound. If in doubt, DO
NOT USE, MARK AS DAMAGED AND DISCARD
• Make sure the machine’s mounting flange is compatible with the superabrasive wheel.
Refer to the manufacturer’s mounting instructions
• ALWAYS conduct a test run after mounting, with no load for at least 30 seconds, to
determine if the wheel runs balanced and does not produce excessive vibration. If it
does produce excessive vibration, switch off IMMEDIATELY, remove the disc, inspect,
re-mount and re-test if no damage is detected
• If planning on using the superabrasive wheel with a coolant, liquid dust suppressant
or lubricant, first check if the wheel, machine and workpiece are compatible with wet
cutting and with the compound to be used. Always apply liquid to an already running
wheel, never to a non-moving tool, as the unbalance could lead to the rupture of the
wheel. When switching off, remove the liquid supply first and let the machine run at
no-load, until centrifugal forces have drained all liquid from the wheel. Dry off the wheel
after use, and prevent liquid from being absorbed into the wheel

Power Tool Use & Care
a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was
designed
b) Do not use the power tool if the switch does not turn it on and off. Any power
tool that cannot be controlled with the switch is dangerous and must be repaired
c) Disconnect the plug from the power source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the risk of starting the power
tool accidentally
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users
e) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired before use. Many accidents
are caused by poorly maintained power tools
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control
g) Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could
result in a hazardous situation
Service
a) Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained
Grinding Tool Safety
• Always wear appropriate personal protective equipment. When using a grinder,
adequate eye protection, ear defenders and breathing protection must be worn
• When operating the grinder, it is a legal requirement that the correct type of guard is
installed for each application to prevent injury. For example, a cutting guard must be
installed when using a cutting or diamond disc, and a grinding guard must be used
with grinding discs
• Reset the guard if the work angle or the position of the person operating the machine
changes. Seek professional guidance if you are unsure how to operate the guards or
any other safety features of the machine correctly
• DO NOT operate a grinder without the appropriate guards in place
• Grinding tool accessories must be mounted, used and stored in compliance with the
manufacturer’s recommendations
• Use plain or centre-recessed cutting or grinding discs in sizes stated in this instruction
manual. Attempting to use any other accessory or attachment is extremely dangerous
and could lead to serious injury
• Use the correct type of cutting or grinding disc for the task and material being worked
on. Check the label on the disc or accessory to find out if it is appropriate to use on
the workpiece
• The maximum speed of the cutting/grinding disc or other accessory must always be
higher than the maximum speed of the machine on which they are mounted
• Do not use any form of spacers or adapters in an attempt to make an incorrectly sized
disc fit your machine
• Ensure that the cutting/grinding disc or accessory is fitted correctly and securely
before use. Run the machine with the disc or accessory fitted, but without load, for a
reasonable time before attempting to cut/grind. If excessive vibration occurs, stop the
machine, investigate and correct the cause before use. Seek professional guidance if
you are in doubt about how to operate the machine safely.
• All discs and accessories must be checked before installation. If a disc is damaged
in any way, such as by being chipped, fractured, warped or misshapen, DO NOT USE
AND DISCARD. If you are unsure about whether a disc is safe to operate, DO NOT USE
AND DISCARD
• Always ensure that accessories are suitable to use. Check the expiry date on the label.
Resin-based and other grinding and cutting discs CANNOT SAFELY BE USED beyond
their expiry date
• Do not allow discs to become wet or contaminated with oil. If you suspect that a disc
has degraded in storage, or if you are unsure about whether its expiry date has passed,
DO NOT USE AND DISCARD
• Do not attempt to cut or grind magnesium or any alloy that has high magnesium
content
• Do not attempt to make cuts that exceed the maximum cutting depth of the disc
• Hold the machine appropriately to ensure that debris produced does not land on skin
or clothing
• Do not operate the spindle lock while the grinder is running
• Discs will continue to rotate for some time after the machine has been switched off.
Allow the moving parts to stop completely without interference. Do not try to stop the
machine by holding an object against the disc. NEVER place the grinder down until the
disc has completely stopped moving
• A grinding disc will gradually wear down during use, reducing its size. If a disc becomes
too small to work with easily, stop using it and replace it with a new disc

• Ensure that all parts of the tool are present and in good condition. If any parts are
missing or damaged, have such parts replaced before attempting to use this tool.
Preparation
WARNING: Always unplug the grinder from the mains supply before attempting to fit or
replace any attachment. Never fit any attachment with a maximum speed lower than the
no load speed of the machine.
• All discs and accessories must be subjected to a visual inspection prior to installation,
to ensure they are in good condition and within their expiry date. If in doubt, DO NOT
USE AND DISCARD
• Always check all parts and attachments are secure, and that rotating parts will not foul
on guards or machine case
• Always hold the machine, using both hands, by the handles provided
• Be aware that the cast metal gear housing may get hot during use
• Hot air will be emitted from the ventilation holes
• Ensure that the ventilation holes are not obscured in any way
• Always wear appropriate personal protective equipment for the task. Use of this
machine requires ear defenders, eye protection, gloves, breathing protection, and, if
appropriate, a hard hat
