IF THE SAW DOES NOT OPERATE
1 Check that the air supply is switched on.
2 Check air supply is correct.
3 Valve in handle (part no. 50034) could be worn and/or the seal is
broken, blocking an air passage. Check and replace if necessary.
4 Valve unit (Part No. 8308) may be stuck. IT IS IMPERATIVE TO
REMOVE THE SAW FROM THE AIRLINE BEFORE
COMMENCING THIS CHECK.
Remove the two hexagonal nuts, push
out valve piston with a pencil, keeping note which end is top. Clean
with oil only, NEVER USE ABRASIVE. Clean valve bore with oil, re-
fit piston from top, keeping the seal at the top end. Tighten nuts and
reconnect saw to air supply.
REPLACEMENT OF PISTON SEALS
1 Each seal consists of two rings, replacements must be fitted as
follows: -
2 Place the elastic ring in the centre of the piston groove, ensuring it is
not twisted
3 Fit the Stiffer sealing ring on top of the elastic ring, Use some green oil
to ease its passage over the piston.
4 Fit the pistons into the bores using a ring compressor, with a coating of
Cengar Green oil, and ensure they slide smoothly over the full travel
range.
PIPE CUTTING WITH THE JSZ
1. Fit the post into the appropriate side of the clamp, the cut line will be
50mm (2”) away from the nearest side face of the foot.
2. Position the clamp on the pipe, with the chain around, and tighten with
spanner provided. Ensure that the clamp is perpendicular to pipe for a
square cut.
