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 inadequate clearance from, an energized
conductor. Do not go closer than the minimum safe
approach distance as defined by ANSI or national
safety regulations.
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 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 particular
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 im-
proper voltage output of the AC generator. Cold 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 manifold air preheater. 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 manu-
facturer (refer to Figure 8.). The serial number placard
is mounted on the front ot the turntable.

Refer to the engine manufacturer below for specific cold
weather start-up information for that particular engine
type and cold weather start system.
Cummins – Block Heater
Plug in the heater cord 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.
Deutz – Manifold Preheater
At the lower controls, hold the manifold heater switch on
for about a minute before turning the master switch to
start the engine. A glow plug in the manifold preheats the
air to help start the engine. Continue to hold the switch
while starting the engine. Do not release the switch until
the engine starts.
If the engine does not start within 20 seconds, continue
to hold the manifold heater switch and turn the master
switch off. Wait for one minute before trying to start the
engine again.
Hydraulic System Cold Weather Warm-Up
The hydraulic oil may be warmed by bottoming out the
boom extension cylinder. Raise the main boom so it is
horizontal and operate the boom retract function while
the machine is stowed. With the cylinder bottomed out
the oil flow will produce heat to warm the hydraulic oil.
