• Ensure 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
• Do not allow discs to become wet or contaminated with oil. If you suspect a disc has degraded in
storage, or if you are unsure 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
• Hold the machine appropriately to ensure that debris produced does not land on skin or clothing
• Do not touch the spindle lock button while the tool is operating
• 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
Additional Safety For Super Abrasives
• 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, 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

Unpacking Your Tool
• Carefully unpack and inspect your tool. Fully familiarise yourself with all its features and functions
• 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
Before Use
WARNING: Ensure the tool is disconnected from the power supply before attaching or changing any
accessories, or making any adjustments.
WARNING: Never fit any attachment with a maximum speed lower than the no load speed of the machine.
Note: 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 the
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
Fitting the auxiliary handle
WARNING: To ensure operator safety, ALWAYS use the Auxiliary Handle (8). Install in the most appropriate
position for the individual task.
1. Screw the Auxiliary Handle clockwise into one of the three mounting points. Tighten by hand
Note: The Auxiliary Handle can be mounted left, right, and above the gear housing.
2. To remove the handle, unscrew anti-clockwise
Adjusting, removing and installing the wheel guards
WARNING: The correct guard MUST be installed for each application before operation commences. WARNING:
NEVER install a cutting disc or superabrasive cutting wheel without the correct cutting wheel guard in place.
Note: The guard must be adjusted so that it is situated between the disc and the operator. Reset the guard if
the work angle or the position of the operator changes. Seek professional guidance if you are unsure how to
operate the guards or any other safety features of the machine correctly.
Note: The grinder is supplied with the Grinding Guard (9) pre-installed.
Adjusting the guard
1. Open the Quick-Release Clamp (11) (Image A)
2. The guard can be moved through a range of approximately 90°, so that it can be placed between the disc
and the operator at any required work angle
3. Close the Quick-Release Clamp
Note: If the Quick-Release Clamp is too loose or too tight, open completely and adjust the lever tightening
screw.
Removing the guard
Note: Skip Step 1 if no disc is installed.
1. Depress the Spindle Lock Button (13), rotate the Spindle (15) until you feel the lock engage. Use the Pin
Spanner (18) to remove the Outer Flange (16) and remove the disc
2. Open the Quick-Release Clamp (11), rotate the guard until the protrusions on the band of the guard are
aligned with the notches on the gear housing (Image B), and remove the guard
