4.1.
air supply (Recommended hook-up procedure is shown in fig.1.)
4.1.1.
ensure tool air valve (or trigger) is in "off" position before connecting to the air supply.
4.1.2.
You will require an air pressure of 90psi, and an air flow according to specification.
WarNiNG! ensure the air supply is clean and does not exceed 90 psi while operating the tool. Too high an air pressure and unclean air
‰
will shorten the product life due to excessive wear, and may be dangerous causing damage and/or personal injury.
4.1.3.
drain the air tank daily. Water in the air line will damage the tool.
4.1.4.
Clean air inlet filter weekly.
4.1.5.
line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be
1/4" I.d. and fittings must have the same inside dimensions.
4.1.6.
Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
4.2.
coupliNGs
4.2.1.
Vibration may cause failure if a quick change coupling is connected directly to the tool. To overcome this, connect a leader hose to the
tool. A quick change coupling may then be used to connect the leader hose to the air line recoil hose. See fig.1 & fig.2.
5. Disc fittiNG
WarNiNG! disconnect from the air supply before changing disc.
‰
5.1.
Use hex key to remove socket head cap screw and washer.
5.2.
Place the cutting disc onto the spindle.
5.3.
Replace the washer and secure with socket head cap screw, but Do Not over tighten. Check that replacement disc is not damaged,
(cracks, deformations or splinters etc). Also check the mounting washer to ensure it is not deformed, burred or notched. A damaged
washer must not be used as it may cause irregular pressure on the disc which may cause it to break.
Do Not tamper with a disc in order to adapt it to a different size holder.

6. opEratioN
WarNiNG! ensure you have read, understood and apply safety instructions.
‰
6.1.
Connect the tool to the air supply.
6.2.
To start the tool, hold firmly and push the trigger locking lever forward whilst depressing trigger.
6.3.
The disc must be running at its maximum speed before attempting to cut the workpiece.
6.4.
Slowly and smoothly bring the cutting disc toward the workpiece (avoid jerky movements).
6.5.
exert adequate pressure on the tool to allow cutting according to the type and size of the material you are working with. Avoid subjecting
disc to excessive strain, always hold tool firmly and ease disc against workpiece (a harsh impact may break the disc). maintain a
controlled adequate progression. Do Not allow tool to free run for an extended period of time as this will shorten its bearing life.
7. maiNtENaNcE
WarNiNG! disconnect tool from air supply before changing accessories, servicing or performing maintenance. Replace or repair
‰
damaged parts. Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
7.1.
lubricate the air tool daily with a few drops of Sealey air tool oil dripped into the air inlet to prolong its life.
7.2.
Clean the tool after use.
7.3.
loss of power or erratic action may be due to the following:
a)
excessive drain on the air line. moisture or restriction in the air pipe. Incorrect size or type of hose connectors. To remedy
check the air supply and follow instructions in section 4.
b)
Grit or gum deposits in the tool may also reduce performance. If your model has an air strainer (located in the area of the
air inlet), remove the strainer and clean it. Flush the tool out with gum solvent oil or an equal mixture of SAe no 10 oil and
paraffin. Allow to dry before use.
7.4.
For a full service contact your local Sealey service agent.
7.5.
When not in use, disconnect from air supply, clean tool and store in a safe, dry, childproof location.
