Warning
• Stop the engine and allow the machine
to cool down before performing
maintenance.
· The engine, muffler, radiator, hydraulic
lines, sliding parts and many other
parts of the machine are hot
immediately after the engine is
stopped. Touching these parts will
cause burns.
• The high-pressure pipes of the air
conditioner can be very hot (80 to 120°C
or 176 to 248°F). Be careful not to burn
yourself.
IMPORTANT: Do not let any oil or grease
get on the belt. It will cause the belt to
slip, decrease the cooling capacity or
shorten the service life of the air
conditioner.
If the belt is too slack, it will slip and vibrate,
resulting in decreased cooling capacity. The
service life of the air conditioner also will be
shortened. Adjust the belt tension to the
standard value.
