OPERATING TIPS
Defrosting and Defogging the Windscreen
The cab windscreen and side windows can be cleared of ice and fog in
two ways. The first is to use the MAX defrost mode (See MAX Defrost
Section on page 88). The second is to manually adjust the air distribution
dial to the defrost position.
During extreme cold weather, do not blow hot defroster air onto cold
windscreens. This could crack the glass. T urn the air flow control dial
to defrost and adjust the fan speed accordingly while the engine warms.
If the engine is already warm, move the temperature control dial to cool,
then gradually increase the temperature when you see the windscreen is
starting to warm up. Failure to comply may result in equipment damage.
Manual Windscreen Defrosting/Defogging
The manual defrost/defogging mode differs from the MAX defrost mode by
allowing the driver to select an air temperature other than full heat. This
allows the driver to maintain a constant cab temperature while defrosting
the windscreen. Note however that performance may be reduced.
Step 1
Adjust the fan speed to high by rotating the fan control dial
clockwise.
Step 2
Set the air distribution dial to the defrost mode setting. This
automatically engages the outside air and A/C compressor.
Step 3
Adjust the temperature dial to add heat as needed. For
maximum performance, adjust the temperature to maximum
heat by rotating the temperature dial clockwise.
The driver may also use the floor/defrost setting on the air control dial to
maintain a clear windscreen while providing heat to the floor. This setting
may be helpful in conditions where the windscreen re-fogs. To increase
the effectiveness of the defroster, engage the A/C compressor.
