Cleaning the main filter
Use clean and dry compressed air with a max.
pressure of 500 kPa (5 bar).
1. Direct the air flow against the inside of the filter
along the folds. Do not hold the nozzle closer than
3-5 cm.
2. Then direct the air flow against the outside of the
filter along the folds and after this against the inside
of the filter again.
3. Check the filter and its sealing surfaces by
means of a torch. Replace the filter if any holes or
other defects are discovered.
IMPORTANT: See service instructions
and replace safety filter in the air
cleaner (maintenance every
1000 hours or yearly).
9.1.3. Maintenance cooling system
The following action should be taken to make sure
that the cooling system functions correctly:
- Check the coolant level (see maintenance
program daily checks).
- Check the fan belt tension (see maintenance
program weekly checks).
- Clean the radiator honeycomb externally by
means of compressed air or by flushing through
with water.
9.1.3.1. Coolant
The cooling system is filled with a mixture of water
and anti-freeze agent on delivery. The anti---freeze
agent also has the property of preventing rust from
forming in the cooling system. However, the anti-
rust properties of the agent diminish with time so
that it is important to change the coolant at regular
intervals. A suitable mixture is half anti-freeze agent
and half water but the manufacturer’s directions
should always be followed.
