If a hoist ever exhibits any sign of erratic operation, or load control di ffi culties (i.e. load creeping or chattering) appropri-
ate troubleshooting tests and repairs should be performed immediately. Continued operation in this manner may result in
property damage, serious personal injury or death.
TROUBLESHOOTING
TROUBLE PROBABLE CAUSE REMEDY
A
Th e hoist will not lower the load or not
lower the load smoothly.
1. Th e problem could be a plugged or
loose pilot ori fi ce. Th e pilot ori fi ce is
a small pipe plug with a hole drilled
through it, located behind the pilot port
fi tting on the brake valve. If it becomes
plugged, it will prevent the pilot pres-
sure, from the manifold, from opening
the brake valve. If it becomes loose, it
will allow an unregulated amount of
oil in to operate the brake valve which
cause erratic brake valve operation.
2. Th e friction brake may not be releas-
ing as a result of a defective brake cyl-
inder seal.
NOTE: If the brake cylinder seal is de-
fective you will usually fi nd oil leaking
from the hoist vent plug.
1. Remove pilot hose and fi tting from
brake valve, then use a 5/32 inch Al-
len wrench to remove pilot ori fi ce. Th e
diameter of the ori fi ce is approximately
.020 inches. Clean and install pilot ori-
fi ce tightly in the brake valve.
2. Check brake cylinder seal as follows:
a. Disconnect the swivel tee from the
brake release port. Connect a hand
pump with accurate 0-2000 psi gauge
and shut-o ff valve to the –4 J.I.C. fi tting
in the brake relea
se
port.
b. Apply 1000 PSI (6,900 kPa) to the
brake. Close shut-o ff valve and let stand
for fi ve (5) minutes.
c. If there is any loss of pressure in fi ve
(5) minutes, the brake cylinder should
be disassembled for inspection of the
sealing surfaces and replacement of the
seals. Refer to “Motor Support-Brake
Cylinder Service”.
