Accumulator - Relieving Charge
To relieve the accumulator charge, with no load on the hook and the engine stopped, move the hook control lever from
"HOLD" to "RAISE" 10 times.
Boom Control (4)
A) HOLD: The lever self centres to this position whenever it is released. In this position, the boom winch brake will
set, and the boom will stop and remain at the position it is in.
B)
LOWER: Move the lever to this position to lower the boom. The further the lever is pushed away from HOLD,
the faster the boom will lower. The closer the lever is toward HOLD, the slower the boom will lower. When the lever is
released, it will return to the HOLD position, and the boom will stop and remain at the position it is in. Boom winch line
speed varies with engine throttle setting. Boom control is smoothest at engine speeds faster than idle.
C)
RAISE: Move the lever to this position to raise the boom. The further the lever is pulled away from HOLD, the
faster the boom will raise. The closer the lever is toward HOLD, the slower the boom will raise. When the lever is
released, it will return to the HOLD position, and the boom will stop and remain at the position it is in. Boom winch line
speed varies with engine throttle setting. Boom control is smoothest at engine speeds faster than idle.
Boom Stop Valve
The Boom Stop valve is a safety device that is intended to automatically stop the boom winch from hauling-in when the
boom is vertical, preventing overloading of key machine components. Refer to the Operation and Maintenance manual,
Boom Stop Valve Adjustment, for correct operation and adjustment. Check its function daily.
