MAINTENANCE/SERVICE
Cab Air System
WARNING: The air conditioning
system is pressurized. Improper
servicing may cause refrigerant to
penetrate eyes and skin or cause
burns. Special equipment and procedures are
required to service the air conditioning system.
See your Windrower dealer for service.
If an accident involving refrigerant should
occur, see a doctor familiar with this type of
injury immediately.
CAB TEMPERATURE CONTROLS
See "Operator's Station" section for information
regarding the use of the various controls affecting
cab temperature.
AIR CONDITIONING CONDENSER
Clean daily with compressed air. See "Screens
and Coolers" under cooling system maintenance.
FRESH AIR INTAKE FILTER
Clean daily as follows:
1. Loosen knob (A) and slide retainer out to
release filter (B) from rear of cab roof.
2. Tap filter gently on a flat surface, dirty side
down. Do not tap on a tire, treads may damage
filter pleats.
3. Direct compressed air (100 psi [700 kPa]
maximum) through filter in opposite direction of
air flow arrows.
4. Wash filter as required:
- Soak 15 minutes in warm water (not over 100
°F
[40
°C]) with Filter Element Cleaner, (Donaldson
D 1400 or equivalent).
- Rinse thoroughly with clean water, (maximum
pressure 40 psi [275 kPa]).
- Shake excessive water from filter and allow
element to dry. Do not use compressed air to
dry filter; it may rupture the wet element.
Protect element from freezing until dry.
5. Reinstall filter, making sure air flow arrows point
towards cab.
CAUTION: The standard cab air
intake filter is not designed to filter
out harmful chemicals.
Follow the chemical manufacturer's
instructions carefully when operating around
spray areas. For use with the MacDon Sprayer,
a replacement charcoal filter is provided.
NOTE:
1. The refrigerant utilized in this machine is
R134a. Total system refrigerant capacity is 1.36
kg (3 lbs.). The compressor oil is SP-15 PAG.
Total system oil requirement is 240 cc (8.1 U.S.
fl.oz.). This amount of oil is included in a new
compressor.
To prevent premature system failure, do not
use refrigerant R12 and/or its oil. Use of
improper refrigerant or oil voids warranty.
2. Service must be performed by a qualified
R134a technician only.
