Sealey SA342 - Manual (Page 2)

3.1 air supply
recommended hook-up procedure is shown in fig.1.
3.1.1 ensure air saw trigger is in "off" position before connecting to the air supply.
3.1.2 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 90psi 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.
3.1.3 drain the air tank daily. Water in the air line will damage the tool.
3.1.4 clean air inlet filter weekly.
3.1.5 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 internal dimensions.
3.1.6 Keep hose away from heat, oil and sharp edges. check hose 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 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 (fig.2). Availably from your sealey dealer (model no. - AH2r)

4.1 saw operation
4.1.1 loosen the two set screws (fig.3c) and adjust the work guide (fig.3d) to suit the job. tighten the set
screws.
4.1.2 ensure that your workpiece is properly secured and, if necessary, marked out.
4.1.3 start the saw by pushing the safety catch forward (fig.3f), then pushing the trigger (fig.3G) down
Do not attempt to start the saw with the stationary blade in contact with the workpiece. start the saw and
bring the moving blade onto the workpiece.
4.1.4 the maximum blade speed may be regulated by turning the valve screw (fig.3H).
4.1.5 if the cut ends within the sheet material allow the blade to come to a stop before removing the saw from
the workpiece.
4.1.6 if the cut starts within the bounds of the material cut a starter slot by hand.
4.1.7 do not allow the saw to run without load for any length of time as this will damage the bearings.
4.2 to change the blade
4.2.1 disconnect the saw from the airline.
4.2.2 undo the screw and open the hinged chuck cover (fig.3A).
4.2.3 slightly loosen one of the two blade retaining set screws (fig.3B) and remove the blade (fig.3e).
4.2.4 slide new blade into place and tighten the loosened set screw (fig.3B). check that blade is fitted with the
cutting edge towards the chuck cover (fig.3A).
4.2.5 close chuck cover and retain with screw.
