To operate the warm-up system:
1. Start the engine and place the engine throttle in the
low position.
2. From the same control station that the engine was
started, place the warm-up switch in the on position.
3. After the hydraulic fluid reaches 10°C (50°F) as indi-
cated on the thermometer, place the warm-up switch
in the off position.
Manually Warming The Hydraulic System
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 char-
acteristics 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 0°C
(10°F) or below.
Preparing for Operation
Use the following procedure to prepare the aerial plat-
form for operation.
1. Perform a prestart inspection as described in Chapter 7.
2. Place the battery disconnect switch in the on position.
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 con-
trol emergency stop button.
Boom, turntable, and platform functions may be oper-
ated from the lower controls. The lower controls may be
used for initial set up of the aerial platform, and for test-
ing and inspection.
Use the following procedure to operate boom, turntable,
or platform functions using the lower controls.
Activate the toggle switch while the start switch is in the
start position to inject a measured amount of ether into
the intake manifold.
Note
Do not crank the engine longer than 20 seconds. If the
engine does not start wait for two minutes before trying
to start the engine again.
Deutz — Manifold Preheater
At the lower controls, hold the manifold heater switch on
for about a minute before starting 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 start switch
off. Wait for one minute before trying to start the engine
again.
GM — Radiator Hose In-Line
Plug the heater cord into a 125 Volt AC, 600 watt source
eight hours before starting the engine. The heater will
warm the water in the lower radiator hose to make cold
weather starting easier.
Unplug the power cord before starting the engine.
Hydraulic System Cold Weather Warm-Up
Some machines may have a hydraulic fluid warm-up sys-
tem that will automatically warm the fluid upon activating
the warm-up switch. The hydraulic fluid may also be
warmed manually if the machine is not equipped with the
optional warm-up system.
A
Caution
Not all hydraulic fluid is suitable to use in the hy-
draulic system. Some have poor lubricating char-
acteristics 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 0°C
(10°F) or below.
Hydraulic System Warm-up Switch
This system may be used to warm the hydraulic fluid
when the ambient temperature is below 0°C (32°F ) and
boom movement is sluggish because of cold fluid.
There may be a toggle switch for the warm-up system on
the lower control panel and/or one on the left side of the
upper control panel.
The engine must be running and the switch used to turn
the system on must be at the same location that the
engine was started. For example, if the engine was started
from the lower controls, the warm-up switch at the lower
controls must be used for the system to operate.
