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.
3. While holding the latch arm, pull the spring
plunger out and rotate the “T” handle to lock the
spring plunger in the “out” position.
4. Carefully allow the latch arm to rotate counter-
clockwise under spring power until it stops.
functions, release the control to deactivate backup
pump. Do not operate the backup pump for more
than 30 seconds continuously.
THROTTLE CONTROL (Optional) - This control
increases the engine speed to provide more oil flow
to hydraulic tools. Push and release the throttle
control to increase the engine speed. Push and
release again to return to idle.
EMERGENCY LOWERING (Optional) - If the aerial
lift’s main power source fails, the emergency lowering
control can be used to lower the lift. A needle valve is
located outside the platform. To operate the needle
valve, slowly open by turning counter-clockwise to
lower the boom. Once the boom is lowered, close
the valve by turning clockwise.
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. Always stow the lower boom before lowering
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.
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 outer/
inner boom assembly with the tie down strap and
remove the wheel chocks. Turn the electrical control
system off and disengage the PTO pump drive (when
applicable).
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.
