(Optional)
Inspect the compressor and hydraulic motor
fastenings.
These are located under the cab between the rear
sides of the frame. The components are accessible
from below.
The unit should be run at least five minutes every
week, if possible, to keep the rubber gaskets and
compressor in the system lubricated.
The air conditioning unit should not be run
when the outdoor temperature is below 32°F
(0°C) other than as specified above.
Never work under the roller with the engi-
ne running. Park on a level surface, chock
the wheels and press the parking brake
control.
Open the engine hood while the unit is operating and
check in the sight glass (1) that no bubbles are visible
on the dryer filter. If bubbles are visible through the
sight glass, it is a sign that the level of refrigerant is too
low. If so, stop the unit. There is a risk of damage to the
unit if it is run with insufficient refrigerant.
Check the moisture indicator (2). The color should be
blue; if it is beige the dryer cartridge must be replaced
by an authorized service company.
The compressor will be damaged if the unit
is run with too little refrigerant.
Do not disconnect the hose coupling.
The cooling system is pressurized.
Incorrect handling can result in serious
personal injuries.
The system contains pressurized refriger-
ant. Releasing refrigerants into the air is
prohibited. The refrigerant circuit may only
be repaired by an authorized company.
