Chapter 8 – Operation
The aerial platform may be operated from either the lower
or upper controls.
A
Danger
The aerial platform is not electrically insulated. Death
or serious injury will result from contact with, or in-
adequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach
distance as defined by ANSI or national safety regu-
lations.
Pinch points may exist between moving compo-
nents. Death or serious injury will result from be-
coming trapped between components, buildings,
structures, or other obstacles. Make sure there is
sufficient clearance around the machine before
moving the chassis, booms, or platform. Allow suf-
ficient room and time to stop movement to avoid
contact with structures or other hazards.
The aerial platform can tip over if it becomes un-
stable. Death or serious injury will result from a tip-
over accident. Operate the aerial platform on a firm,
flat, level surface. Avoid travel speeds and/or rough
terrain that could cause sudden changes in platform
position. Do not drive or position the aerial platform
for elevated use near any drop-off, hole, slope, soft
or uneven ground, or other tip-over hazard.
The platform rated work load is the total weight of the
personnel and equipment that may be lifted in the plat-
form. The work loads are stated on the platform rating
placard mounted at the rear of the platform.
A
Danger
The aerial platform can tip over if it becomes un-
stable. Death or serious injury will result from a tip-
over accident. Do not exceed the capacity values
indicated on the platform rating placard.
Capacity values indicate the rated lifting capacity and
do not indicate aerial platform stability.
The operator bears ultimate responsibility for ensuring
that the aerial platform is properly set up for the particu-
lar conditions encountered.
Cold Weather Start-Up
If the ambient temperature is 0°C (32°F) or below, the
engine and hydraulic system oil may need to be warmed
before operation. Do not operate the engine at more than
a fast idle until the engine and hydraulic oil has had a
chance to warm. The engine may be equipped with an
optional cold weather start kit.
Cold, thick hydraulic oil does not flow well and may cause
delay in response to control movement and improper
voltage output of the AC generator. Cold oil may also
cause cavitation and pump damage. The hydraulic sys-
tem may be equipped with an optional cold weather
warm-up kit.
Engine Cold Weather Start Kit
The engine may be equipped with a block heater.
Plug the heater cord in eight hours before starting the
engine. The heater will warm the engine block to make
cold weather starting easier.
Unplug the power cord before starting the engine.
Hydraulic System Cold Weather Warm-Up
Some engines may have a hydraulic fluid warm-up sys-
tem that will automatically warm the fluid upon activat-
ing the warm-up switch. The hydraulic fluid may also be
warmed manually if the machine is not equipped with
the optional warm-up system.
A
Caution
Not all hydraulic fluid is suitable to use in the hy-
draulic system. Some have poor lubricating charac-
teristics and can increase component wear. Only use
hydraulic fluid as recommended.
Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of 10°F
(0°C) or below.
Hydraulic System Warm-up Switch
This system may be used to warm the hydraulic fluid
when the ambient temperature is below 32°F (0°C) and
boom movement is sluggish because of cold fluid.
There may be a toggle switch for the warm-up system
on the lower control panel and/or one on the left side of
the upper control panel.
The engine must be running and the switch used to turn
the system on must be at the same location that the
engine was started. For example, if the engine was
started from the lower controls, the warm-up switch at
the lower controls must be used for the system to oper-
ate.
To operate the warm-up system:
1. Start the engine and place the engine throttle in the
low position.
2. From the same control station that the engine was
started, place the warm-up switch in the on posi-
tion.
3. After the hydraulic fluid reaches 50°F (10°C) as in-
dicated on the thermometer, place the warm-up
switch in the off position.
