4. AIR SUPPLY
Recommended hook-up procedure is shown below.
4.1.
The saw requires an air pressure of between 50-90psi and an air flow of 4cfm.
WARNING! Ensure the air supply is clean and does not exceed 90psi.
‰
Too high an air pressure and/or unclean air will result in excessive wear and may be dangerous, causing damage and/or personal injury.
4.2.
Drain the air tank daily. Water in the air line will damage the saw and will invalidate your warranty.
4.3.
Clean compressor air inlet filter weekly.
4.4.
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.
4.5.
Keep hose away from heat, oil and sharp edges. Check hoses for wear and make certain that all connections are secure.
4.6.
Couplings Vibration may cause failure if a quick-change coupling is connected directly to the air saw. To overcome this, connect a
leader hose (Sealey Part No. AH2R) to the saw. A quick-change coupling may then be used to connect the leader hose to the air line
recoil hose.

‰
NOTE: Numbers in brackets refer to item numbers in the parts diagram.
5.1.
Loosen the two set screws (fig.4.1) and adjust, or change, the work guide (fig.4.2) to suit the job. Tighten the set screws.
5.2.
Ensure that your workpiece is properly secured and, if necessary, marked out.
5.3.
Start the saw and bring the moving blade onto the workpiece.
DO NOT attempt to start the saw with the stationary blade in contact with the workpiece.

5.4.
The maximum blade speed may be regulated by turning the valve screw (fig.3).
5.5.
If the cut ends within the sheet material, allow the blade to come to a stop before removing the saw from the workpiece.
5.6.
If the cut starts within the bounds of the material cut a starter slot by hand.
DO NOT allow the saw to run without load for any length of time as this will damage the bearings.

5.7.
TO CHANGE THE BLADE:
5.7.1.
Disconnect the saw from the air line.
5.7.2.
Undo the screw (fig.4.3) and open the hinged chuck cover (fig.4.4.).
5.7.3.
Loosen one of the two blade retaining set screws slightly (fig.4.5) and remove the blade.
5.7.4.
Slide new blade into place and tighten the loosened set screw. Check that blade is fitted with the cutting edge towards the chuck cover.
5.7.5.
Close the chuck cover and retain with the screw.
