PREPARING SAW FOR USE
3.1.
Air Supply
3.1.1. Remove protective plug from air inlet and connect to the air supply as described below.
3.1.2. You will require an air pressure of 90psi, and an air flow according to the specification above.
3.1.3. p WARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the saw.
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.
3.1.4. Drain the air tank daily. Water in the air line will damage the saw and will invalidate your warranty.
3.1.5. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig 1.
3.1.6. 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.
3.1.7. Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all
connections are secure.
3.2.
Couplings.
Vibration may cause failure if a quick change coupling is connected directly
to the air saw. To overcome this, connect a leader hose to the saw. A quick
change coupling may then be used to connect the leader hose to the air line
recoil hose. See fig 1 & 2.

4. OPERATING INSTRUCTIONS
WARNING! Ensure you read, understand and apply safety instructions before use.
4.1
The saw is designed to cut with the black guide plate flat against the surface being cut. To aid this the
p
cutting blade cuts upwards to help to draw the guide plate down onto the workpiece.
4.2
Loosen the hex bolt at the front of the guide plate and adjust the height of the plate so that the cutting
depth is slightly deeper than the sheet material to be cut.
4.3
Ensure that your workpiece is properly secured and marked out. Rest the leading edge of the saw’s guide
plate onto the edge of the workpiece and align the blade with the previously marked out line.
4.4
When you are satisfied with the alignment, start the saw and progress steadily along the marked line with
the guide plate flat to the cutting surface.
4.5
If the cut stops within the sheet material allow the blade to come to a stop before removing the saw from
the workpiece.
4.6
If the cut starts within the bounds of the material cut a starter slot by hand to drop the blade into.
4.7
Do not allow the saw to run freely for any length of time as this will damage the bearings.
4.8
To change the blade firstly disconnect the saw from the airline. Loosen the hex socket bolt using a 4mm
key and remove the bolt, washer and retaining disc. Lift the blade upwards from its mounting boss and
slide it down and out of the guard. When fitting the new blade, be sure to orientate it so that the teeth will
be cutting upwards. ( see direction of rotation in fig.3.) When replacing the retaining disc make sure that
the two spigots on the back of the disc engage in the slots in the blade mounting boss. Replace the
washer and bolt and fully tighten.
5. MAINTENANCE
WARNING! Disconnect saw from air supply before changing the blade, servicing or performing
maintenance. Replace or repair damaged parts.
p
Use genuine parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
5.1.
Lubricate the air saw daily with a few drops of the air tool oil supplied, dripped into the air inlet before
use. ( To re-order air tool oil use Sealey part Nos. ATO/500 or ATO1000.)
5.2.
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 chapter 3.
b) Grit or gum deposits in the saw 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 saw out with gum
solvent oil or an equal mixture of SAE No 10 oil and kerosene. Allow to dry before use.
If you continue to experience problems, contact your local Sealey service agent.
5.3.
For a full service contact your local Sealey service agent.
5.4.
When not in use, disconnect from air supply, clean saw and store in a safe, dry, childproof location.
