can also be aided by carefully coordinating the throttle
control.
4. Lower loadline and attach load.
5. Control load by use of a non-conductive tag line.
6. Do not leave crane unattended with the boom elevated
in operating position. Always secure the boom in the
boom rest before leaving the work area.
SHUTTING DOWN AND PREPARING FOR
ROAD TRAVEL
1. Completely retract boom and place securely in boom
rest.
2. Secure loadline block so that it cannot swing freely.
3. Anti-Two Block (ATB) Switch to prevent damage to the
ATB switch, consider the following:
With loadline hook stowed properly, verify
downhaul weight is resting against the
terminator wedge socket bracket. Slack in
the chain assembly must be present in
order for weight to be removed from ATB
switch.
DO NOT SHORTEN CHAIN AT ANYTIME.
If slack in the chain assembly is still not
present, add straps between anchor point
and hook block to achieve weight removal
from the ATB switch.
4. Retract all outriggers/stabilizers. Optional front stabilizer
should always be retracted first, before main outriggers
are retracted.
5. Secure any loads or lifting devices on truck bed or body.
6. Disengage Power Take Off (PTO).
7. Release park brake before moving truck.
8. When traveling on the road, check all underpasses to be
sure there is sufficient clearance for the unit.
OPTIONAL HOIST BURST OF SPEED
OPERATION
The “Burst of Speed” will increase hoist line speed 60% over
normal operation by diverting oil from the multibank control
valve to the hoist valve.
The “BOS” is engaged by operating the hoist control valve
lever while pulling up on the BOS handle below the hoist
knob. The “BOS” feature should only be operated in a
temporary manner to reduce oil heat build up, prevent truck
PTO overloading, and provide independent operation of the
crane and hoist (normal hoist speed will not decrease when
crane functions are used). If the “BOS” feature is run
continuously or with an overload, damage to the crane or
truck could occur. To start the “BOS” smoothly, first pull up on
the BOS handle, then operate the hoist lever. To stop the
“BOS” smoothly, return the hoist lever to its neutral position
then release the BOS handle.
Note: Maximum Capacity with “BOS”
• One Part Line - 3000 lb (1361 kg)
• Two Part Line - 6000 lb (2722 kg)
• Three Part Line - 9000 lb (4082 kg)
• Maximum line speed on third layer - 206 FPM (62
mpm), fourth layer - 225 FPM (68 mpm)
