B - EVERY 50 HOURS OF 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, the cartridge inspection and cleaning frequency must be reduced.
The cartridge must not be cleaned more than seven times, after which the cartridge must be changed. Never operate the lift truck with the air filter removed
or damaged.
- For the disassembly and reassembly of the cartridge, see: 3 - MAINTENANCE: D – EVERY 500 HOURS OF SERVICE.
- 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 30mm 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.
- Raise the engine cover (see: 2 - DESCRIPTION: INSTRUMENTS AND CONTROLS).
In order to prevent the radiator becoming clogged, clean it with a compressed air jet directed
from inside to outside. This is the only effective way of removing the impurities.
B3 – WHEEL NUT TORQUES
CHECK
- Check the condition of the tyres, to detect cuts, protuberances, wear, etc.
- Check the torque load of the wheel nuts. Non compliance with this instruction can cause damage and rupture to the wheel bolts and
distortion to the wheels.
B4 – TENSION AND ALIGNMENT OF MAST LIFTING CHAINS
CHECK - ADJUST
Place the lift truck on level ground with the mast in a vertical position and the forks raised
approximately 200 mm.
- Visually check the state of the mast and the forks.
- Check the alignment of the mast lifting chains between the carriage’s chain fasteners and the
chain rollers.
- Manually verify the chain tension, if necessary adjust as following while ensuring that the
carriage is perpendicular to the mast.
- Loosen the nut 1 (fig. B4).
- Loosen the lock nut 2 (fig. B4) of the chain tension adjuster.
- Adjust the tension by tightening or loosening the nut 3 (fig. B4) while checking the alignment
of the lifting chains.
- Then block the lock nut 2 and the nut 3 (fig. B4).
- Retighten the nut 1 (fig. B4).
These checks are important for the good working operation of the mast. In case of technical faults, consult your dealer.
