back-blow with compressed air.
d) Hole in metering screw in valve spool ass’y (743142) may be blocked or damaged. Hole diameter should be
.028". Clear and size or replace.
3. NO OPERATION WHEN LEVER ASS’Y (724017) IS DEPRESSED
a) Tool seized due to mechanical failure or damaged parts.
4. OIL LEAKAGE

DO NOT
OPERATE WITH OIL LEAKING FROM TOOL. HIGH PRESSURE OIL MAY CAUSE SEVERE PERSONAL
