TION

1. Transmission is full of fl uid.

2. Pump case is full of oil.

3. Suction hose is full of oil.

4. Ground controls have been selected.

5. Oil reservoir is full.

6. Pump hoses are clear of drive line and
exhaust

system.

7. Shutoff valve in suction line is open.

Start the engine and release the clutch gradually
to rotate the pump as slow as possible. The pump
and PTO should operate quietly. If excessive
noise occurs check for these problems.

1. Improper backlash of PTO.

2. Hydraulic pump is not primed.

3. Air leak in the suction line.

4. Shutoff valve in the suction line is not open.

Once the hydraulic pump is operable, the ground
controls can be operated.

CAUTION:

REMOVE TOOLS, SLINGS,

HARDWARE, AND ANY OTHER LOOSE OBJECTS
BEFORE OPERATING THE MACHINE. FALLING
TOOLS MAY CAUSE SERIOUS INJURY TO
PERSONNEL.

CAUTION:

OPERATE THE LIFT FROM

THE LOWER CONTROLS FOR SEVERAL CYCLES
TO PURGE THE AIR FROM THE HYDRAULIC
SYSTEM.

Upper Boom Rest, Lower Boom Rest and
Platform Support -

The weight of the stored

upper boom should be supported by the boom
rest, not the hydraulic cylinder. A lower boom
rest is also required. The platform should also be
supported when stowed. Detailed instructions on
the installation are included on the “Boom Rest
and the Platform Support” and “Lower Boom
Rest Installation” drawing in Parts & Assemblies
Section.

CAUTION:

TO AVOID STRESS OR

DAMAGE TO THE UNIT THE WEIGHT OF A
STORED BOOM SHOULD BE SUPPORTED BY
THE BOOM REST AND NOT BY THE HYDRAULIC
CYLINDER.

Engine Start/Stop Control -

Mount the engine

start/stop control box inside the cab to protect it
from water. Wire the start/stop system according

to schematic in the Parts & Assemblies Section.

10.

Manual Throttle Control (Optional) -

If the

engine start/stop control has been installed,
locate the electrical box adjacent to the start/stop
electrical box. Electrical power for the throttle
control can be taken from terminal six in the start/
stop control electrical box. Wire according to
the wiring schematic in the Parts & Assemblies
Section.

Mount the throttle-actuator solenoid in the
engine compartment. Refer to the “Throttle
Control Solenoid Mounting” illustration in Parts
& Assemblies Section for mounting instructions.
Adjustment of the engine speed will be discussed
later.

11.

Emergency Hydraulic Power (Optional) -

Connect the hydraulic lines as shown on the
hydraulic schematic section. The check valve
shown with the emergency power must be
installed as shown on the schematic to prevent
leakage back through the primary pump.

Wire the motor as illustrated on the electrical
schematic.

CAUTION:

FAILURE TO PRIME THE

PUMP BEFORE INITIAL OPERATION MAY CAUSE
PUMP DAMAGE.

If the emergency power motor fails to respond,
make certain the truck ignition switch is on. If the
motor still does not operate, it may be insulated
from the mounting by paint. The motor must be
grounded directly to the truck body or frame.

PREDELIVERY TESTING AND INSPECTION

The American National Standards Institute Standard
A92.2 entitled “American National Standard for
Vehicle-Mounted Elevating and Rotating Aerial
Devices” requires that each aerial device be tested to
ensure compliance with the prescribed requirements.
Such predelivery testing and inspection are the
responsibility of the fi nal installer. All paragraphs
identifi ed by number are part of ANSI A92.2.

Section

7.5 Installations

reads in part as follows,

“The installer of an aerial device shall, before the

mobile unit is placed in operation, perform stability
tests in accordance with requirements of 4.5.1
and 4.5.2, and the operational and visual tests in
