OPERA
TION
CAUTION
:
TO PREVENT DAMAGE TO
THE UNIT DO NOT DRIVE THE TRUCK UNTIL THE
AERIAL LIFT IS STORED AND THE OUTER BOOM
IS SECURED WITH THE BOOM TIE DOWN STRAP.
CAUTION:
DRIVING WITH THE PTO
ENGAGED MAY DAMAGE THE TRANSMISSION,
PUMP, AND THE PTO.
AUTO BOOM LATCH (Optional)
– The automatic
boom latch is designed to open automatically when
the lift is operated. Stay clear of the latch as it may
move at any time depending on the hydraulic system
pressure.
Manual over-ride
– In case of hydraulic system
failure, the auto boom latch may be operated
manually.
Over-ride Procedure:
1.
Danger
– Make sure the hydraulic power source
is off.
2.
Release the spring plunger by rotating the “T”
handle.
3.
Manually rotate the latch arm 90° clockwise until
it snaps and is held by the spring plunger.
To Release Over-ride:
1.
Caution
– The latch is spring loaded. Keep
fingers clear to prevent pinching.
2.
Slightly rotate the latch arm clockwise to remove
the load from the spring plunger.
and release it. It is recommended that the engine be
left at idle until faster lift movements are required. This
practice will provide efficient operation and minimize
fuel consumption. During hydraulic tool operation the
oil flow will be adequate to operate the tools at idle
speed.
BACKUP PUMP CONTROL (Option)
- The backup
pump system is operated by a spring-loaded toggle
switch.
The backup pump system should not be
operated longer than 30 seconds continuously.
Continuous use will drain the battery and damage (over
heat) the backup pump motor.
To activate this system from the upper controls,
push and hold the toggle switch in the “ON” position
while operating the lift controls.
To turn off the backup pump from the upper
controls,
release the toggle switch and allow it to
return to the neutral position.
STORING THE AERIAL LIFT
When storing the aerial lift for road travel retract the
inner boom completely. Rotate the outer/inner boom
assembly until it is centered over the boom rest.
Rotate the platform so the bottom of the platform is
centered over the platform support. Always stow the
lower boom before descending the outer/inner boom
assembly onto the boom rest. Release the outer/
inner boom control lever as soon as there is firm
contact with the boom rest pad. The platform will
also contact the spring-loaded platform support.
CAUTION
:
FAILURE TO STOW THE
LOWER BOOM BEFORE DESCENDING THE
OUTER/INNER BOOM ASSEMBLY ON TO THE
BOOM REST WILL STRESS THE COMPONENTS
AND MAY CAUSE DAMAGE TO THE AERIAL
LIFT.
DANGER
:
ALWAYS WATCH FOR
PERSONNEL AND OBSTRUCTIONS WHEN
STORING THE AERIAL LIFT. A CRUSHING INJURY
TO PERSONNEL OR DAMAGE TO THE UNIT CAN
OCCUR.
To complete the storing procedure secure the upper
boom with the tie down strap, retract the outriggers,
and remove the wheel chocks. Turn the electrical
control system off and disengage the PTO pump drive.
