SERVICE & MAINTENANCE
9.4 Hydraulic pump station
The hydraulic pump station is made up of a motor, pump, oil tank and so on. After the Forklift is used for one year,
the oil should be replaced. Replacement could be done as follows:
• Park the Forklift on a flat surface.
• Bring the forks to the lowest position in order for the oil to circulate back to the tank.
• Loosen the lock screws of the footrest and remove the footrest.
• Put the oil dish in the bottom of the oil tank and loosen the sucking oil pipeline to let off the oil.
• Take out the mesh filter from the oil tank and clean it with kerosene.
• Fit the mesh filter on the oil tank and connect the sucking oil pipeline.
• Using the funnel with a mesh filter, pour in oil to about 80% of the oil tank height.
• Reconnect the filler plug and footrest.
9.5 Forks and Forks holder plate
The forks holder plate slide on the holder plate to make the forks move up and down. The lift forks holder plate
should be checked to inspect if the limit screws on the two sides are operating appropriately. If the limit screws
are too tight, the forks holder plate cannot slide freely. If too loose, the forks holder plate will shake. The forks
should be checked after 500 hours of usage. Any faulty forks must be taken out of service immediately and
cannot be used again until they have been repaired or replaced.
The fence must be fixed after the forks are fitted on the lift forks holder plate. If not, the forks that slide from
the two sides of the forks holder plate can lead to malfunctioning.
If the fork thickness has been reduced to 90% of the original thickness due to wear, you must stop using them
and need to be replaced immediately.
9.6 The Lifting Chain
As there are no fixed rules as regards to the frequency and checking of the chains. If there is a lot of dusts on
the chains, the chain should be cleaned and re-lubricated. In the normal case, after having worked for 1000
hours, the chains should be removed and washed, check wear & tear of the chain and measure elongation. If
the chains have a lot of wear and elongation exceeds 2%, the chains must be replaced. Replace coupling pin,
coupling screw together with their respective nuts when replacing the chains. The chains should be
re-lubricated after cleaning and replacing the chains.
