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 inadequate 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 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 mov-
ing 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 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
platform.
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 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 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 voltage 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).

Refer to the engine manufacturer below for specific cold
weather start-up information for that particular engine
type and cold weather start system.
Cummins, Kubota 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.
Cummins – Ether Injection
Some Cummins engines may have an ether injection
system instead of a block heater. Ether injection should
only be used to start a cold engine when the ambient
temperature is below 32°F (0°C).
Make sure there is a can of ether installed in the holder,
in the engine compartment on the right side of the ma-
chine. Use the following procedure to install a can of
ether as necessary.
1. Place the battery disconnect switch in the off posi-
tion.
2. Unscrew the holding cup.
3. Place a new can of ether in the cup.
4. Screw the holding cup firmly into position.
