behind the transmission. If the weight is reduced
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.
After the truck has been properly parked on level
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 (A-Frame
outriggers only). 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, 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 “Hydraulic Oil Recommendations” in Service
Procedures Section of the Service Manual.
After the outriggers (if so equipped) have been
lowered, disengage the upper-boom tie-down strap.
Select lower controls with the selector lever. 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) operate it
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 operating
