Section 3. Boom
adjusting screw on each cartridge simulta-
neously into the cartridge very slowly
clockwise. Hydraulic oil from inside the
hoist cylinders will escape through the fault
in the line.
3. If the line failure is in the boom lowering line
the boom must be lowered by following the next
3 steps:
(a) At the base of each hoist cylinder, locate
the counterbalance valve cartridges, Fig. 3-
19. Loosen the retainer nut on each
cartridge and turn the adjusting screws in
(clockwise) until they bottom out. Doing
this will render each counterbalance valve
inoperative.
(b) Clear the area around the machine of all
personnel and return to the operators cab.
(c) Move the boom control lever forward to
lower the boom.
IMPORTANT: This procedure is to be used in
emergency situations only. By turning the counter-
balance cartridge adjusting screws to lower the
boom, the pressure settings of the cartridge have
been altered. DO NOT attempt to reset these
cartridges. Remove and replace all three cartridges
with new parts. Failure to replace these cartridges
with new parts will result in erratic (extreme bounc-
ing) lowering action, which may cause damage to
other components.
