Operation
SB66JRT 9
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 defined by national safety regulations.
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 ac-
cident. 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 per-
sonnel and equipment that may be lifted in the platform.
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 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 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 improper volt-
age 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.
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.
A
Caution
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.
Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of
-12°C (10°F) or below.
Preparing for Operation
Use the following procedure to prepare the aerial platform
for operation.
1. Perform a prestart inspection as described in the
“Daily Preventative Maintenance Checklist” on page
16.
2. Place the battery disconnect switch in the on posi-
tion.
3. Close and latch the doors.
4. Before painting or sandblasting make sure the sand-
blast protection kit and the platform control cover are
properly installed. These options, when used properly
will protect the control placards and cylinder rods from
paint overspray and abrasion while sandblasting.
Lower Controls
The lower controls override the upper controls. This
means that the lower controls can always be used to
operate the platform regardless of the position of the
upper control emergency stop button.
Boom, turntable, and platform functions may be operated
from the lower controls. The lower controls may be used
for initial set up of the aerial platform, and for testing and
inspection.
Use the following procedure to operate boom, turntable,
or platform functions using the lower controls (ref: Figure
3 on page 6).
