OPERATING CONTROLS AND PROCEDURES CD15 OPERATOR MANUAL

OPERATING CRANE CONTROLS
Four levers in the operator’s cab control the crane functions.
See Figure 3-26. These levers are connected directly to the
main control valves.
When operating each control, press the accelerator pedal to
increase engine speed to maximum RPM. Slowly move the
control lever. The farther the control lever is moved the faster
the function will operate. To stop function movement, move
the control lever to the neutral position, then lower the engine
speed to idle.
Anti-Two Blocking System
See Figure 3-27
This system inhibits the hook block or the downhaul weight
from being pulled into the boom or jib head during boom
extension, boom raising, and load hoisting operations.
If the hook block or the downhaul weight contacts the anti-
two-block bracket under the boom head or the anti-two-block
lever under the jib head, the limit switch is actuated.
The limit switch stops hydraulic oil flow to the telescope out,
boom lift, and hoist motor raise functions. A horn is activated
to give a warning to the operator in all cases.
Before operation can resume, the hook block or the
downhaul weight must be lowered away from the boom or jib
head.
NOTE: DO NOT disconnect the anti-two-block system.
Possible damage to the boom, hoist or crane could
result.
