B - EVERY 50 HOURS SERVICE
Carry out the operations described previously as well as the following operations.
B1 - DRY AIR FILTER CARTRIDGE
CLEAN
In case of use in a heavily dust laden atmosphere, there are pre-filtration cartridges (see: 3 - MAINTENANCE: FILTERS CARTRIDGES
AND BELTS). Also, the checking and cleaning periodicity of the cartridge must be reduced.
If the clogging indicator light comes on, this operation must be carried out as quickly as possible (1 hour maximum). The cartridge must not be cleaned
more than seven times, after which the cartridge must be changed.
- For the disassembly and reassembly of the cartridge, see: 3 - MAINTENANCE: D3 - DRY AIR FILTER CARTRIDGE.
- Clean the filter cartridge using a compressed air jet (max. pressure 3 bar) directed from the top to the bottom and from the inside
towards the outside at a minimum distance of 30 mm from the cartridge wall.
- Cleaning is completed when there is no more dust on the cartridge.
Respect the safety distance of 30 mm between the air jet and the cartridge to avoid tearing or making a hole in the cartridge. The cartridge must
not be blown anywhere near the air filter box. Never clean the cartridge by tapping it against a hard surface. Your eyes must be protected during this
intervention.
- Clean the cartridge seal surfaces with a damp, clean lint-free cloth and grease with a silicone lubricant (MANITOU reference:
479292).
- Check visually the outer condition of the air filter and its mounts. Verify the condition of the hoses and their mounts also.
Do not clean the dry air filter cartridge by washing it in liquid. Do not clean by any means the safety cartridge located inside the filter cartridge, change
it for a new one if it is dirty or damaged.
B2 - RADIATOR CORE
CLEAN
In a polluting atmosphere, clean the radiator core every day. Do not use a water jet or high-pressure
steam as this could damage the radiator fins.
- Open the I.C. engine bonnet.
- If necessary, clean the suction grid on the engine bonnet.
- Using a soft cloth, clean the radiator in order to remove as much dirt as possible.
- Clean the radiator using a compressed air jet aimed in the same direction as the cooling
air flow (fig. B2).
- So as to enhance the cleaning, carry out this operation with the fan running.
B3 - CONDENSER CORE (OPTION AIR CONDITIONING)
CHECK - CLEAN
In a polluting atmosphere, clean the radiator core every day. Do not use a water jet or high-pressure
steam as this could damage the condenser fins.
- Visually check whether the condenser (fig. B3) is clean and clean it if necessary.
- Clean the condenser using a compressed air jet aimed in the same direction as the air flow.
- So as to enhance the cleaning, carry out this operation with the fans running.
