B - EVERY 50 HOURS 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.
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. 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: 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.
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 if it is clogged or damaged.
B2 - RADIATOR CORES
CLEAN
The compressed air can cause accidents. While using compressed air, wear a protective device for the face
and protective clothing. The maximum pressure of the compressed air at the nozzle outlet must be 2 bar (30 PSI).
Check the radiator (water Fig. B2/1; oil Fig. B2/2)
for: damaged fins, corrosion, dirt, grease, insects, leaves, oil or other debris.
Direct the compressed air jets in the direction of the arrows.
Keep the air nozzle at a distance of about 6mm from the radiator fins.
Also use pressurized water to soften mud or solid debris.
The maximum water pressure must be less than 2.7 bar (40 PSI).
To remove oil and grease, use a degreaser and steam. Clean both sides of the radiator mass.
Wash the radiant mass with detergent and boiling water. Rinse the radiant mass thoroughly
with clean water.
After cleaning the radiator/s, start the I.C. engine, keeping it running at minimum for about
five minutes.
Bring the I.C. engine to maximum operating speed without load (this operation helps to remove
debris and to dry the radiant mass). Gradually reduce the I.C. engine speed to the minimum
and stop it.
Use a light to check behind the radiant mass to see if it is clean.
If necessary, clean again.
Check to see if fins are damaged. Bent fins can be straightened using a “comb”.
Check to make sure the following elements are in good condition. welded parts, mounting
brackets, piping, connections, clamps and gaskets.
Carry out repairs, if necessary.
