lift is operating properly and to purge any air the
hydraulic system.
If there is any malfunction during this empty 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
byconstantly 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 must
be started and stopped gradually.
DANGER:
NEVER START, 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.
The range each boom will raise and lower is
mechanically limited. An operator must always be
aware of these mechanical limits and avoid reaching
the end of the boom’s range at an excessive speed.
To do so stresses the lift and chassis unnecessarily
and may cause instability. Notice that rotation is not
limited. The lift can rotate continuously.
Operating Procedures From 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 to be secured
with a personnel restraint system to the lift. The safety
belt must be secured around the waist. The lanyard
is a connecting strap. The “Energy Absorber” end of
the lanyard always connects to the body belt or
harness and the other end connects to a lanyard
anchor at the platform support weldment. The safety
belt must be rotated so that the lanyard connection is
centered on his back.
DANGER:
NEVER OPERATE ANY
AERIAL EQUIPMENT WITHOUT WEARING AN
APPROVED PERSONNEL RESTRAINT SYSTEM
ATTACHED TO THE ANCHOR. FAILURE TO
PROPERLY 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 aerial device operator
understand the dangers associated with operating near
electrical hazards. Due to the work involved, the
ordinary uses of aerial lift often place the operator and
ground crew in the vicinity of electrical lines and
equipment where grave danger exists. These dangers
can only be avoided by the constant care of an operator
who is aware of these dangers, knows the limitations
of the aerial lift and its insulating sections, and knows
how to protect himself and the crew from these
dangers.
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.
The insulation capabilities of this aerial lift are defined
by the rated line voltage on the ANSI A92.2 data plate.
Although the aerial unit provides insulated booms, no
aerial lift can provide protection from contact with or
proximity of an electrically charged power line when
you are in contact with or in proximity of another power
line. Maintain safe clearances from electrical power
lines in accordance with applicable government
regulations. Make certain to allow clearance for boom,
platform, electrical line, and load line sway and
deflection.
DANGER:
CONTACT WITH OR
INADEQUATE CLEARANCE FROM ELECTRICAL
POWER LINES AND APPARATUS WILL CAUSE
DEATH OR SERIOUS INJURY.
The accumulation of dirt and moisture on insulated
booms degrades the insulation. Be sure the booms
are clean and dry. Remember that the inside of a
boom may be wet even when the outside is dry. Any
equipment which bridges the platform and the ground
voids the insulation and must be eliminated when
working near areas of electrical hazard.
