Chapter 8 – Operation
The aerial platform may be operated from either the lower
or upper controls.
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.
Pinch points may exist between moving components.
Death or serious injury will result from becoming
trapped between components, buildings, structures,
or other obstacles. Make sure there is sufficient clear-
ance around the machine before moving the chassis,
booms, or platform. Allow sufficient room and time
to stop movement to avoid contact with structures
or other hazards.
The aerial platform can tip over if it becomes unstable.
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 ter-
rain 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
at the:
rear of the platform
lower controls
upper controls
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. 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 particular
conditions encountered.
Cold Weather Start Up
If the ambient temperature is 32°F (0°C) or below, the
engine and hydraulic system oil may need to be warmed
up 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 volt-
age output of the optional AC generator. Cold hydraulic
oil may also cause cavitation and pump damage. The
hydraulic system may be equipped with an optional cold
weather warm-up kit.
Engine Cold Weather Start Kit
The optional engine cold weather start kit may be an
engine block heater or a radiator hose in-line heater. The
type of starting assist system depends on the engine
manufacturer.
The last two letters of the model number stamped on the
serial number placard indicates the engine manufacturer
(refer to Figure 8.1).

Note:
Machines equipped with a Hatz engine do not have an
optional engine cold weather start kit.
Refer to the engine manufacturer below for specific cold
weather start-up information for that particular engine
type and cold weather start system.
Continental, Cummins and Ford — Block Heater
Plug the heater cord into a 125 Volt AC, 600 watt source
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.
General Motors — Radiator Hose In-Line
Plug the heater cord into a 125 Volt AC, 600 watt source
eight hours before starting the engine. The heater will
warm the water in the lower radiator hose to make cold
weather starting easier.
Unplug the power cord before starting the engine.
Hydraulic System Cold Weather Warm-Up
Some machines may have a hydraulic fluid warm-up
system that will automatically warm the fluid upon acti-
vating the warm-up switch. The hydraulic fluid may also
be warmed manually if the machine is not equipped with
the optional warm-up system.
Caution
Not all hydraulic fluid is suitable to use in the hy-
draulic system. Some have poor lubricating charac-
