Chapter 8. Operation
The aerial platform may be operated from either the
lower or upper controls.
The aerial platform is not electrically insulated.
Death or serious injury can result from contact with,
or inadequate clearance from, an energized con-
ductor. Do not go closer than the minimum safe ap-
proach distance as defined by ANSI.
Pinch points may exist between moving compo-
nents. Death or serious injury can 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 suffi-
cient room and time to stop movement to avoid con-
tact with structures or other hazards.
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury can 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.
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 on the toeboard at the front of the plat-
form.
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury can result from a
tip-over accident. Do not exceed the capacity val-
ues 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 32°F (0°C) 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 low
voltage output of the AC generator. Cold hydraulic oil
may also cause cavitation and pump damage. The hy-
draulic 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 en-
gine block heater or a manifold air pre-heater. The type
of starting assist system depends on the engine manu-
facturer.
The last two letters of the model number stamped on the
serial number placard indicates the engine manufac-
turer (refer to Figure 8.1). The serial number placard is
mounted on the front of 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.
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.
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
main boom cylinder. Operate the main boom down func-
tion while the machine is stowed. With the cylinder bot-
tomed out the oil flow will produce heat to warm the
hydraulic oil.
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.
