OPERA
TION
WINCH - This control raises and lowers the winch
line.
JIB EXTENSION (Optional) - This control extends
and retracts the jib-pole.
STORING THE AERIAL LIFT
Storing the booms for road travel requires a
combination of boom/platform lowering and rotating
movements. Prior to lowering the boom into the rest,
it must be centered over the rest. The aerial lift design
will allow either the upper boom or the lower boom to
be stored first with no adverse effects.
DANGER:
ALWAYS WATCH FOR
PERSONNEL AND OBSTRUCTIONS WHEN
STORING THE AERIAL LIFT. A CRUSHING INJURY
TO PERSONNEL OR DAMAGE TO THE UNIT CAN
OCCUR.
STORING THE LOWER BOOM - As the lower boom
approaches the boom rest, the operator should use
the lift controls to reduce the speed of the lower boom’s
descent.
STORING THE UPPER BOOM - Store the upper
boom into the boom cradle carefully.
STORING THE JIB AND WINCH - To prevent jib pole
damage and for minimum travel height and rear
overhang, tilt the jib-pole to horizontal. Then fully retract
the jib-pole before stowing the upper boom.
CAUTION:
FAILURE TO PROPERLY
STOW THE JIB-POLE ASSEMBLY INCREASES
THE TRAVEL HEIGHT OF THE UNIT AND WILL
CAUSE DAMAGE IF PASSING UNDER A LOW
OBSTACLE.
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.
CAUTION:
TO PREVENT DAMAGE
TO THE UNIT DO NOT DRIVE THE TRUCK UNTIL
THE AERIAL LIFT IS STORED AND THE UPPER
BOOM IS SECURED WITH THE UPPER BOOM TIE-
DOWN STRAP.
CAUTION:
DRIVING WITH THE PTO
ENGAGED MAY DAMAGE THE TRANSMISSION,
PUMP, AND/OR 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.
