23. Make sure the booms are properly stowed, raise
the outriggers, disengage the PTO, and turn off the
engine.
Preparing for Operation
Before using this unit each day, the shift preoperational
inspection must have been performed. This unit may be
operated in accordance with the following procedure on
rm surfaces. Consider the reach of the unit and the work
to be done when positioning the unit.
1. Place the transmission in neutral and apply the park-
ing brake. Apply the supplemental holding brake, if
equipped.
WARNING
Park on a rm surface before operating the unit. Set
parking brakes, outriggers must be extended as in-
structed under Outriggers. Take into consideration
pad loads on all surfaces.
It is impossible to foresee all situations and combinations
for set up of the unit. Establish criteria for stable operation
of the unit based on actual conditions, work procedures,
and experience. The owner and operator bear ultimate
responsibility for ensuring that the unit is properly set up.
2. Engage the PTO according to the manufacturer’s
operating instructions.
3. If equipped, move the truck/machine selector switch
in the vehicle cab to the Machine position.
CAUTION
Injury can result from slipping and falling. Use care
and the handles and steps provided.
NOTICE
Do not put the unit in service and run the pump at
normal operating speeds until the hydraulic oil res-
ervoir feels warm to the touch.
4. If the temperature is below 32 degrees Fahrenheit
(0 degrees Celsius), warm the hydraulic oil before
operating the unit. The procedure for warming the
oil is described under Cold Weather Start-Up in this
section. Do not operate the pump or engine at more
than a fast idle until the hydraulic oil has warmed up.
5. The unit has outrigger controls on the tailshelf. These
controls are only functional when the crane/outrigger
switch is in the Outrigger position. Properly set the
outriggers to level the unit as described in Section
6 under Outriggers.
6. While operating the unit, continuously monitor the
outriggers and booms for any unintended movement
that could be an indication of a malfunction. Stow the
unit and remove it from service if any malfunction is
suspected.
Cold Weather Start-Up
When operating the unit in temperatures of 32 degrees
Fahrenheit (0 degrees Celsius) or below, follow the cold
weather start-up procedure. Refer to the Maintenance
Manual for cold weather oil recommendations.
NOTICE
Only use hydraulic oil as recommended. Other uids
added to the hydraulic system can increase compo-
nent wear and affect the lubricating characteristics
of the oil.
Do not put the unit in service and run the pump at
normal operating speeds until the hydraulic oil res-
ervoir feels warm to the touch.
The engine and pump speeds should be no greater than
a fast idle until the oil has warmed up. Cold, thick oil
does not ow well and may cause delays in response to
control movement, as well as cavitation and consequent
pump damage.
Use the following procedure to warm up the hydraulic oil.
1. Start the vehicle engine and engage the PTO.
2. Operate the boom retract function, allowing the oil
to bypass over a relief valve for a few minutes.
3. With the machine properly set-up, extend the boom
fully, retract, and repeat step 2 above.
