B - EVERY 50 HOURS SERVICE

B1 – DRY AIR FILTER CARTRIDGE
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 it must be changed. Never use the lift truck without an air filter or with a damaged air filter.
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.
Never 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
- For the disassembly and reassembly of the cartridge, see: 3 - MAINTENANCE: E1 - 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.
- 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.
