ELECTRICALLY INSULATED.
ENSURE THAT HANDS and
clothing are kept away from rotating
parts.
ONLY YOUR SUPERVISOR OR
AUTHORISED MAINTENANCE
ENGINEER should adjust the speed
control setting within the air motor;
although this has been set to the
optimum speed during manufacture,
the speed should be checked on a
daily basis.
ENSURE THAT THE WORK PLACE
IS WELL VENTILATED. Avoid
o p e r a t i n g e n g i n e - p o w e r e d
compressors in an enclosed area,
since engine exhaust gases are
poisonous.
BE AWARE, when the angle grinder
is switched off, the work head will
continue to rotate briefly.
The grinder must never be used
without a wheel guard fitted.
The air supply should be lubricated. It is
strongly recommended that an air filter,
regulator, lubricator is used, this will
supply clean, lubricated air at the correct
pressure to the tool.
Details of such equipment can be
obtained from your supplier.
If such equipment is not used then the
tool should be lubricated by shutting off
the air supply to the tool, depressurising
the line by pressing the trigger on the
tool.
Disconnect the air line and pour into the
air intake a teaspoonful (5ml) of a
suitable pneumatic motor lubricating oil
preferably incorporating a rust inhibitor.
Reconnect tool to air supply and run tool
slowly for a few seconds to allow air to
circulate the oil. If tool is used frequently
lubricate on daily basis and if tool starts
to slow or lose power.
Putting into service
Remove plastic bung from air inlet
using a pair of pliers.
Use a clean lubricated air supply that
will give a measured air pressure to
the tool of 6.3bar (90psi).
It is recommended a air filter/regulator/
lubricator is used which can be
obtained from air tool supplier.
Recommended lubricants
Oil the tool daily during use. Put a few
drops of one of the following bio-
degradable air tool lubricants through
the air inlet.
SHELL Naturelle HF
CASTROL Carelube HTG 22
Always use clean oil from a sealed
container.
Risk of Hand-arm Vibration
injury
These tools may cause Hand-arm
Vibration Syndrome injury if their use
is not adequately managed.
We advise you to carry out a risk
assessment and to implement
measures such as; limiting exposure
time [i.e. actual trigger time, not total
time at work], job rotation, ensuring the
tools are used correctly.
Ensure the tools are maintained
according to our recommendations,
and ensuring that the operators wear
personal protective equipment [PPE]
particularly gloves and clothing to
keep them warm and dry.
Employers should consider setting up
a programme of health surveillance to
establish a benchmark for each
operator and to detect any early
symptoms of vibration injury.
We are not aware of any PPE that
provides protection against vibration
injury by attenuating vibration
emissions.
See ‘Specifications’ section for
vibration emission data.
Grinding Discs, Flap Wheels &
Applications
Grinding Discs
For use on steel.
Flap Wheel
For the removal aggressive removal of
paint and coatings and heavy rust from
steel work, leaving a bright finish on
steel work.
Wire Cup Brush
For the removal of light paint, other
coatings and rust from steel work.
Use of tool
This angle grinder is designed for use
with reinf orc e d resin bond ed
depressed centre grinding wheels that
have a permitted rotational speed in
excess of 10,000rpm.
The tool is designed for light grinding
and dressing of welds, etc, but not for
cutting off.

OPERATION
Pre-Start Check (Daily)
Check all bolts and screws for
tightness.
Ensure that all fittings are secure.
Check condition of hub or drum
assembly and replace flaps, cutters or
axles if required.
The air motor speed is preset at the
factory to 10,000 rpm (free running).
Always clear the air hose before
connection to the machine.
E n s u r e t h a t n o m o i s t u r e
(condensation) is present in the air
hose.
Check the security of all hoses clamps
and fittings, and that the air pressure is
correct at 90psi (6.2bar). The air motor
uses approximately 10cfm of air.
The Maximum air pressure is 100psi
(7bar) the air consumption will
increase as the air pressure rises.
It i s r e c o mm e n d e d t ha t th e
compressor is capable of supplying at
least 30cfm supply of free air (not
displaced, as given by some
compressor manufactures).
In particularly cold weather it is
recommended that a proprietary anti-
freeze lubricating oil is used.
Operating
With the grinder correctly connected to
the air supply, check the speed of the
grinder with an inlet pressure of 100
psi/7.0 bar measured at the tool inlet.
Check with a calibrated tachometer.
Check that the guard is in position and
securely fixed.
Check that the grinding wheel is of
correct dimensions, is not cracked or
chipped and has a permitted speed
rating higher than the maximum
permissible running speed of the
grinder which is 10,000 RPM.
Check that item disc receiver is
screwed tightly to the shaft and locates
the bore of the grinding wheel on the
spigot of the disc receiver and screw on
disc nut item (40) using the spanners
provided.
Do not over tighten as this could crack
the wheel. It should be tight enough to
prevent wheel spin off when the air
supply is shut off.
When first starting the grinder with a
new or changed wheel fitted, the
grinder should first be started in a
protected area, i.e. such as under a
heavy bench well away from other
persons and run for one minute.
This will provide protection if the wheel
should break because of a fault that
was not visibly detected.
Always use eye protection and wear
protective gloves if there are sharp
edges in the working area.
The tool and the grinding process can
create a noise level such that ear
protectors should be worn.
If the grinding process creates dust
then use a suitable breathing mask.
Check that the material being worked
will not cause harmful dust or fumes. If
this is so then special breathing
apparatus may be required. Seek
advice before starting work.
If the grinder vibrates when first fitting
the wheel or during use, remove from
service immediately and arrange for the
fault to be corrected before continuing
to use.
Do not apply excessive pressure as this
will reduce the cutting efficiency.
Apply light loads and allow the wheel to
cut.
Handle the grinder with care.
If the grinder is dropped, carefully
examine the wheel for damage and
replace if necessary.
Start the machine as if for the first time
of fitting a wheel, i.e. under a bench.
Make sure the object to be worked on is
in a securely fixed position.

2) Do not exceed the maximum working air pressure.
3) Use personal protective safety equipment.
5) If the tool appears to malfunction remove from use immediately and arrange for service and repair.
6) If the tool is used with a balancer or other support device ensure that it is fixed securely.
7) Always keep hands away from the working attachment fitted to the tool.
8) The tool is not electrically insulated. Never use the tool if there is any chance of it coming into contact with a live electrical
source.
9) Always when using the tool adopt a firm footing and/or position and grip the tool firmly to be able to counteract any forces
or reaction forces that may be generated whilst using the tool.
10) Use only correct spare parts. Do not improvise or make temporary repairs.
11) Do not lock, tape, wire, etc. the on/off valve in the run position. The trigger/lever etc. must always be free to return to the
‘off’ position when it is released.
12) Always shut off the air supply to the tool, and depress the trigger/lever etc. to release air from the feed hose before fitting,
adjusting or removing the working attachment.
13) Check hose and fittings regularly for wear. Replace if necessary. Do not carry the tool by its hose and ensure the hand is
remote from the on/off control when carrying the tool with the air supply connected.
14) Take care against entanglement of moving parts of the tool with clothing, ties, hair, cleaning rags, etc. This will cause the
body to be drawn towards the tool and can be very dangerous.
15) Users will adopt safe working practices and observe all relevant legal requirements when installing, using or maintaining
the tool.
16) Do not install the tool unless an easily accessible and easily operable on/off valve is incorporated in the air supply.
17) Take care that the tool exhaust air does not cause a problem or blows on another person.
18) Never lay a tool down unless the working attachment has stopped moving.
19) A grinding wheel should only be fitted by a competent person trained to do so. The wheel must be of the correct size and
speed rating.
20) Check the speed of the grinder at least once per week, if it is in regular use, with an accurate tachometer.
21) The tool must only be used with the grinding wheels as set out in section “Use of the Tool” and shown on parts list. Never
fit any other device.
22) Carry out the instructions as set out in “Putting into Service”.
23) Many countries have local or national rules re the use and fitting of grinding wheels. Make sure such rules are observed.
24) Use a barrier to prevent sparks causing a hazard to the operator, any other person or anything within the vicinity of the
sparks.
25) If a wheel guard becomes damaged or has withstood a wheel breakage, the guard must be changed.
26) Do not use chipped or cracked grinding wheels.
27) Always wear impact resistant eye protection.
28) Use only the disc plates, Items (38) and (40) provided with the grinder for locating and clamping the wheel. Never use
substitutes. Use the paper blotter fixed to the wheel as this ensures even tightness when the wheel is secured.
29) Tighten the wheel plates sufficiently to prevent wheel spin off when the grinder is turned off. Do not tighten excessively as
this may crack the wheel.
30) The noise from the tool or the process noise of the grinding operation may be such that hearing protection should be
worn.
31) Avoid inhaling dust from the grinding process. Wearing of a breathing mask is recommended. Grinder certain materials
may mean that special breathing precautions are necessary. Seek advice before using the tool.
32) Always ensure that the work piece is firmly supported so that it cannot move during the grinding process.
33) If the grinder is dropped do not use unless the wheel is first checked for damage by a competent person.
34) When not in use the grinder should be stored in a safe place where it will not be damaged. If a tool has not been used for
a period of time check the tool as for the first time of using.
35) Be aware that if the grinding process causes high vibration, special precautions should be taken.
36) The operator should be aware that the grinding wheel will continue to rotate after the power supply has been shut off. This
could cause a hazard.
37) Always store grinding wheels in accordance with the manufacturer’s instructions.
38) Check frequently that the spindle thread has not become damaged or worn.
39) Always ensure that the grinding wheel has a higher permissible running speed to the speed of the grinder.
