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 defi ned 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 suffi cient
clearance around the machine before moving the
chassis or platform. Allow suffi cient 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 fi rm, fl at,
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 entrance to the platform.
A
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.
Cold, thick hydraulic oil does not fl ow well and may cause
delay in response to control movement. Cold hydraulic oil
may also cause cavitation and pump damage.
Manually Warming The Hydraulic System
The hydraulic oil may be warmed by bottoming out the
platform lift cylinder. Lower the platform so the cylinder
is bottomed out; the oil fl ow will produce heat to warm
the hydraulic oil.
A
Caution
Not all hydraulic fl uid is suitable to use in the hy-
draulic system. Some have poor lubricating charac-
teristics and can increase component wear. Only use
hydraulic fl uid as recommended.
Use cold weather hydraulic oil as recommended in the
machine General Specifi cations in temperatures of 10°F
(0°C) or below.
Preheat Button
The preheat button is used to warm the engine if the
ambient temperature is 32°F (0°C) or below.
With diesel engines, the preheat switch will activate
the glow plugs.
Figure 8.1 – Lower Controls
When starting a diesel engine from the upper or lower
controls (refer to Figures 8.1 and 8.4):
If the engine is cold, press and hold the preheat
button for approximately fi ve seconds before
starting the engine.
Preparing for Operation
Use the following procedure to prepare the aerial platform
for operation:
1. Perform a prestart inspection (refer to Chapter 7).
2. Close and latch the doors.
3. Place the on/off switch in the on position.
