JUMP STARTING HAZARD
Do not attempt to jump start the crane.
All crane models, particularly those produced since 2000,
have multiple computer systems (crane control, RCL, engine
& transmission control) that are highly susceptible to voltage/
amperage surges in the electrical system.
The batteries should be completely disconnected from the
crane electrical system and charged using a battery charger
of appropriate voltage level or replace the batteries with fully
charged batteries. Refer to Charging the Battery, page 3-2.
CHARGING THE BATTERY
When charging the batteries, do not turn on the battery
charger until the charging leads have been connected to the
battery(s). Also, if the battery(s) are found to be frozen, do
not attempt to charge them. Remove the battery(s) from the
crane, allow them to thaw, and then charge the battery(s) to
full capacity.
“Slow charging” is preferred to “fast charging”. Fast charging
saves time but risks overheating the battery(s). Slow
charging at six (6) amps or less develops less heat inside the
battery and breaks up the sulfate on the battery plates more
efficiently to bring the battery up to full charge. The use of a
“smart charger” that automatically adjusts the charging
amperage rate should be used.
TRUCK CAB CONTROLS
The truck cab controls described here are those controls that
are used in conjunction with the crane controls.
Truck Cab Ignition Switch
Truck Cab Ignition Switch must be ON in order for the crane
ignition switch to be operable.
NOTE: All ignition switches (truck key switch and both
crane console switches must be in the RUN/ON
position before the truck can be started from either
the truck cab or the control console.
Power Take Off
The PTO must be disengaged when crane is not being
operated to prevent power drain to the battery. Power is
supplied by the truck battery even when the truck ignition is
in the OFF position.
PTO is recommended to be disengaged when starting for
ease of cranking engine.
Manual Shift Control
The Power Take Off (PTO) switch varies by truck chassis.
The PTO is engaged when the knob on the dash or floor is
pulled out and disengaged when the knob is pushed in. The
truck gear shift lever must be in neutral and the clutch
depressed whenever the knob is moved.
Air Shift Control
The PTO is engaged when the switch is moved to apply air to
the PTO and disengaged when the switch is in the off
position. The truck gear shift lever must be in neutral and
clutch depressed when the switch is moved. The
transmission selector lever must be returned to “N” for
stationary vehicle operation. The PTO can be disengaged
while in any transmission range provided that the load has
been removed from the PTO.
Electric Shift Control
Full torque electric shift PTO’s are controlled by a switch. To
operate, disengage the clutch, shift to fourth or fifth gear, and
push the switch down to engage the PTO or up to disengage
the PTO. Return the gear shift to neutral and engage the
clutch.
Power Shift Control
If the vehicle is equipped with an automatic transmission, the
power take-off must be engaged with the engine at idle. See
transmission manufacturer’s instructions for special
procedures.
CAUTION
It is strongly recommended that the batteries not be
“jumped” with a different vehicle, portable power pack,
etc. The surge of power from these sources can
irreparably damage the various electronic controls and
computer systems. Jump starting the crane batteries
with a different vehicle while the engine is running can
damage the donor vehicle electronics as well if done
improperly.
CAUTION
Disengage the hydraulic pump when crane is not in active
use. Leaving the PTO engaged will cause batteries to
drain.
