Additional Safety Instructions for
Pneumatic Power Tools
Air under pressure can cause severe injury:
• Always shut off air supply, drain hose of air pressure and disconnect tool from air supply when
not in use, before changing accessories or when making repairs
• Never direct air at yourself or anyone else
• Whipping hoses can cause severe injury. Always check for damaged or loose hoses and fittings
• Whenever universal twist couplings (claw couplings) are used, lock pins should be installed and
whipcheck safety cables should be used to safeguard against possible hose-to-tool or hose-to-
hose connection failure
• Do not exceed the maximum air pressure stated on the tool
• Never carry an air tool by the hose
Grinding Tool Safety
• Always wear appropriate personal protective equipment. When using a grinder, adequate eye
protection, ear defenders and breathing protection must be worn
• 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
• Only use cutting discs in the size 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
• 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
Intended Use
Angle grinder using 100mm (4”) diameter discs, powered by compressed air from a compressor, for
grinding and cutting of metal and other materials .
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:
Always disconnect the angle grinder from the air 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 tool housing may get hot during use
• 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 quick connector
Note:
This tool is supplied with two different male airline quick connectors:
EQ-4 – commonly used in Europe
EN-6 – mainly used in the UK
• Please choose the connector that is compatible with the airline system you are using, and install
as outlined below:
1 . Apply some PTFE tape (not included) to the screw threads of the Quick Connector (11). This will help
to maintain an air tight seal
Note:
Apply PTFE tape tightly and in a clockwise direction, so it does not come off when the thread
is screwed into the tool.
2 . Remove the protective plug from the air inlet
3 . Using a spanner (not included) screw the quick connector into the air inlet located at the base of
the handle
4 . Connect to airline, pressurise carefully and carry out a leak check (e .g . by spraying small amounts of
soapy water on to the outside of the connectors)
• Air lines fitted with matching female quick connectors will now be a push fit to the tool
Fitting the auxiliary handle
WARNING:
To ensure operator safety, ALWAYS use the Auxiliary Handle (8) .
1. Screw the auxiliary handle clockwise into the mounting point on the left side of the tool
housing . Tighten by hand
2. To remove the auxiliary handle, unscrew anti-clockwise
Fitting a disc
WARNING:
Disconnect the tool from the air supply before fitting or changing discs.
• Find the flat faces on the Spindle (3) and engage them with the Spanner (7), so that the spindle
is held securely and not able to rotate
• Use the Pin Spanner (6) to loosen the Threaded Flange (4)
• Remove the threaded flange and discard the old disc if fitted
• Fit a new disc of correct size (see ‘Specifications’), following the manufacturer’s guidance for
direction of rotation
Note:
Unless otherwise stated, the metal ring at the centre of the disc should face the spindle.
• Re-fit the threaded flange, ensuring it is not deformed, burred or notched, and tighten using the
spanner and pin spanner
WARNING:
A damaged flange may cause irregular pressure on the disc, and may cause it to break.
