OMPRESSED AIR SUPPLY
Many of problems come from a faulty or inadequate
compressed air supply system. Before attempting to repair
the tool, the following points should be checked:
a) check the pressure at the output of the compressor;
adjust to 80-100 psi (5.5-7.0 bar) as required
b) check the tank pressure of the compressor & adjust the
start/stop limits
c) check the air delivery system; a 3/8" hose is
recommended
d) use fewer tools simultaneously; do not exceed the
capacity of the compressor or of the delivery system
e) drain water from the compressor

d) Check the driving blade for broken end
e) Check piston wear-ring P-622A; replace if piston is
sliding to easily
f) Check seal bushing P-525B
g) Check the adjustment of the base and ensure the tool is

D
RIVING BLADE DOES NOT RETURN
a) Check for jammed fastener or obstruction
b) Check gate/foot and end of feeder channel for damages
