Manitou MH25-4 T BUGGIE 4ST3A - 50-Hour Service Tasks

B - EVERY 50 HOURS OF SERVICE
Carry out the operations described previously as well as the following operations.
B1 – DRY AIR FILTER CARTRIDGE
CHECK - 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.

IMPORTANT

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 replaced.
Never use the lift truck without an air filter or with a damaged air filter.
- For the disassembly and reassembly of the cartridge, see: 3 - MAINTENANCE: D1 - 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.

IMPORTANT

Observe a 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 operation.
- Clean the cartridge seal surfaces with a damp, clean lint-free cloth and grease with a silicone lubricant (MANITOU part
no.: 479292).
- Check visually the outer condition of the air filter and its mounts. Verify the condition of the hoses and their mounts also.

IMPORTANT

Do not clean the dry air filter cartridge by washing it in liquid.
Do not, under any circumstances, clean the safety cartridge located inside the filter cartridge, replace it with a new one if it is clogged or damaged.
B2 – RADIATOR CORE
CLEAN

IMPORTANT

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.
- Lift up the overhead guard or the cab (see: 2 - DESCRIPTION: INSTRUMENTS AND CONTROLS).
- Clean the radiator with jet of compressed air directed from the outside towards the inside. This is the only effective way
of removing impurities (opposite direction to the cooling air flow).
B3 – TYRE PRESSURES AND WHEEL NUT TORQUES
CHECK

IMPORTANT

Check that the air hose is correctly connected to the tyre valve before inflating and keep all persons at a distance during inflation.
Inflate to the recommended tyre pressures.
- Check the condition of the tyres, to detect cuts, blisters, wear, etc.
- Check the torque load of the wheel nuts. Non-compliance with this instruction can lead to damage and failure of the
wheel bolts and distortion of the wheels.
- Check and, if necessary, adjust the tyre pressures (see: 2 - DESCRIPTION: TYRES).
NOTE: There is an OPTIONAL wheel tool kit.
