ground
, and the outriggers have a clear path to
the ground, lower all the outriggers until they firmly
contact the ground. When the ground is too soft for
the outriggers to be effective, place outrigger pads
on the ground to increase the bearing area.
If the truck is
parked on sloping ground
so that one
side of the truck is lower than the other side, extend
the low-side outrigger first so that firm contact is
made with the ground. This will avoid tilting the
truck even more to the low side when the high-side
outrigger is lowered.
If one or both outriggers (of a pair) are not fully
extended, the outrigger spread is reduced. This
reduces the stability of the aerial lift. For example,
when an outrigger rests on a curb the outrigger
spread is reduced.
The stability of the truck depends on the unit’s gross
weight, firmness and slope of the ground, weight in
the platform, or load on the lifting eye, tire pressure,
and outrigger spread. These factors are widely
variable and caution must be used when determining
the stability of the unit. If, under any condition, there
is doubt about vehicle stability do not operate the lift.
AERIAL LIFT OPERATIONS
This section emphasizes overall operating practices
for aerial lift operations. This information is presented
in the order of probable use while operating first from
the ground, then from the platform and close to
energized conductors.
Start Up Procedures When Operating From the
Ground:
Position the truck as described in this section.
In extremely cold weather allow the aerial lift to idle
a few minutes before engaging a load. Further
consideration of cold weather operation is addressed
in Service Procedures Section “Hydraulic Oil
Recommendations” in the Service Manual.
After the outriggers (if so equipped) have been
lowered, disengage the upper boom tie-down strap.
Select lower controls with the control selector. Refer
to this section for a diagram of the lower controls.
Caution: If an aerial device has set idle for an
extended length of time (i.e. overnight); it must be
operated from the lower controls through its full range
of motion several times before an operator enters
the platform.
This procedure confirms that the lift is
from one of the rear wheels, by the position of
the lift, the truck differential can allow the truck
to roll. Refer to Figure 4.1 diagram for proper
way of chocking the wheels.

DANGER:
NEVER OPERATE THE LIFT
WITHOUT SETTING THE PARKING BRAKE AND
CHOCKING THE WHEELS. A ROLLING TRUCK
MAY CAUSE AN ACCIDENT RESULTING IN
DEATH OR SERIOUS INJURY.
3. Set up adequate cones or barricades to mark
the boundaries of the work site and alert
pedestrians and motorists. Never work outside
the boundaries.
OUTRIGGERS (If equipped) - To operate the
outriggers see “Outrigger Controls” in this section.
DANGER:
NEVER OPERATE WITHOUT
EXTENDING THE OUTRIGGERS (IF EQUIPPED).
WITHOUT PROPER OUTRIGGER EXTENSION
THE UNIT MAY TIP RESULTING IN DEATH OR
SERIOUS INJURY.
