OPERA
TION
confirms that the lift is operating properly and purges
any air that may have become entrapped in the
hydraulic system.
If there is any kind of malfunction during this test run,
shut down the unit immediately. Do not operate the
lift again until the problem has been corrected by the
service department.
Operate each lift function from the lower controls by
constantly holding the 3-position selector valve control
handle in the lower controls position while slowly
moving the appropriate spring-loaded control handle
in the desired direction, as indicated by the decal,
until motion begins. All boom movements should be
started and stopped gradually.
DANGER:
NEVER REVERSE OR
STOP THE DIRECTION OF LIFT TRAVEL
SUDDENLY AND AVOID REACHING THE END OF
BOOM RANGE AT EXCESSIVE SPEEDS.
STRUCTURAL DAMAGE OR INSTABILITY MAY
RESULT CAUSING DEATH OR SERIOUS INJURY.
Operating Procedures At The Platform:
Complete the start-up procedure from the ground
before selecting the upper controls with the 3-position
control selector. In order to operate the lift from the
platform, select the upper controls with the 3-position
selector lever at the lower control station. Verify that
the upper-boom tie-down strap is disengaged. Using
the step(s) provided, carefully enter the platform.
Safety regulations require the operator be secured
with a personnel restraint system to the lift. The
lanyard shall be attached to the safety belt/harness
and the other end connected to the lanyard anchor on
the platform support weldment. The safety belt must
be rotated so that the lanyard connection is centered
on the back of the operator.
DANGER:
NEVER OPERATE ANY
AERIAL EQUIPMENT WITHOUT WEARING AN
APPROVED PERSONNEL RESTRAINT SYSTEM
ATTACHED TO THE LANYARD ANCHOR ON THE
PLATFORM SUPPORT WELDMENT. FAILURE TO
SECURE THE SAFETY BELT AND LANYARD
MAY RESULT IN DEATH OR SERIOUS INJURY IN
THE EVENT OF A FALL FROM THE PLATFORM.
Before operating the lift, the operator should study
“Upper Control Operation” in this section.
Operating Where Electrical Hazards Are Present:
It is imperative that the operator understand the
dangers associated with operating near electrical
hazards. Due to the nature of the work operators,
others in the platform, and the ground crew are often
exposed to very high voltage. This danger can only
be avoided by the constant care of an operator who is
aware of, knows the limitations of the aerial lift, and
knows how to protect himself and the crew from these
dangers. Maintain safe clearances from electrical
power lines in accordance with applicable government
regulations. Allow clearance for boom, platform,
electrical line, and load line sway and deflection.
DANGER:
ALL COMPONENTS IN
THE PLATFORM AREA, INCLUDING THE
CONTROLS, JIB POLE, COVERS, ETC. SHALL BE
CONSIDERED ELECTRICALLY CONNECTED, AND
NOT INSULATED OR ISOLATED. THESE
COMPONENTS MAY CONDUCT ELECTRICITY
RESULTING IN DEATH OR SERIOUS INJURY.
DANGER:
THIS AERIAL LIFT
CONSISTS OF A STEEL OUTER BOOM AND A
STEEL INNER BOOM AND HAS NO INSULATING
VALUE. CONTACT WITH OR INADEQUATE
CLEARANCE FROM ELECTRICAL POWER LINES
AND APPARATUS WILL CAUSE DEATH OR
SERIOUS INJURY.
As stated previously, it is the responsibility of the
operator and the ground crew to know and understand
the capabilities and limitations of the aerial lift and
hazards associated with operation near electric lines
or components. In addition they must apply this
knowledge to situations that arise on the job for safe
and efficient operation.
CAB CONTROL OPERATION
The cab controls include the master control, the engine
start/stop control, and the PTO shifter.
MASTER CONTROL (Standard) - The master control
consists of a toggle switch and a light mounted on
the dashboard of the truck. The toggle switch is used
to energize or de-energize the start/stop system and
the throttle control options. When the light is on the
toggle switch is energizing these systems.
ENGINE START/STOP (Standard) - The engine start/
