OPERATING CONTROLS AND PROCEDURES
• Do not exceed a speed of 2.5 mph (4 km/h).
• Ensure main counterweight is installed.
• Position the boom over the front of the crane.
• Engage the swing brake and turntable lock pin.
• Remove hookblock from main boom nose.
• Headache ball may be reeved over boom extension,
hanging 3 ft (0.9 m) below sheave.
33 ft (10.1 m) Extension Plus 40 ft (12.2 m) Insert
Follow the steps below when traveling with the extension
and insert erected.
• Position the 33 ft (10.1 m) boom extension plus 40 ft
(12.2 m) insert at the minimum offset. Stow the stinger
section on the boom base section, not on the extension
base section.
• Travel only on a firm, level surface.
• Fully retract the main boom.
• Limit main boom angle to a minimum of 0° and a
minimum of 20°.
• Do not exceed a speed of 2.5 mph (4 km/h).
• Ensure main counterweight is installed.
• Position the boom over the front of the crane.
• Engage the swing brake and turntable lock pin.
• Remove hookblock from main boom nose.
• Headache ball may be reeved over boom extension,
hanging 3 ft (0.9 m) below sheave.
Extended Travel
Depending upon the tire manufacturer, the higher inflation
pressures normally specified for lifting on rubber are not
recommended for site to site transfer over extended
distances. The higher static/creep 5 mph (8 km/h) inflation
pressures may remain in the tire while operating the crane
on site within a distance of less than 4 mi (6.4 km).
CAUTION
Tire Damage Hazard!
For extended travel, check the cold tire pressure prior to
start. (Refer to tire inflation chart in Load Chart Book.)
After every one hour of travel time, regardless of ambient
temperature, stop and allow the tires to cool off for at least
30 minutes. At the destination, the tires must be allowed
to cool to ambient temperature before crane lifting on
rubber.

Traveling — Forward
Engage the turntable lock pin for extended travel. Failure
to engage the lock pin may allow the superstructure to
swing uncontrolled, damaging the machine and/or
property.
1. With the Transmission Shift Lever in the neutral (N)
position, start the engine and allow it to adequately
warm up.
2. Depress the Service Brake Foot Pedal.
Releasing the parking brake while the low service brake
pressure indicator is illuminated and the buzzer is
sounding, indicating the service brakes are inoperable,
may result in the crane rolling away freely without the
ability of the operator to stop the crane.
Never release the parking brake while the low service
brake pressure indicator is illuminated and the buzzer is
sounding.
3. Disengage the parking brake.
4. Position the Drive Axle Switch to either two-wheel high
or four-wheel low.
Use four-wheel drive only when more traction is required.
5. Lift the Transmission Shift Lever up out of its detent and
push the lever to the forward (F) position, then rotate the
Transmission Shift Lever Knob to the first (1) gear
position. The gear selection "F1" will appear in the LCD
Display to indicate that forward propulsion and first (1)
gear have been selected; if the Service Brake Foot
Pedal is not depressed prior to shifting to a gear, the
gear selection will flash in the LCD Display until the
Transmission Shift Lever is returned to the neutral (N)
position and the transmission will not shift.
6. Release the Service Brake Foot Pedal and depress the
Foot Throttle Pedal until maximum first gear speed is
attained, then rotate the Transmission Shift Lever Knob
to the second (2) gear position to continue to increase
speed. For additional speed, continue shifting to a
higher gear.
