SERVICE & MAINTENANCE
Charging the Battery
•
Open the plug of each element.
•
Check the level of the electrolyte. If the level is under the standard value, you must charge the battery.
•
Insert the plug of the battery into the battery charger socket. Do not insert the plug of the charger into
the electric appliances control plank socket.
•
Start charging the battery.
•
After recharging, check the level of the electrolyte.
•
After 250 hours of usage of the battery, check the tightness of the terminals and protect with anti-acid
grease or neutral Vaseline.
Replace the Battery
Because the battery installed in the Forklift is welded, when replacing the battery, you should use the hook to lift out the
battery and the metal box. Insert the new battery and connect the electrical wire. The battery is ready to be used.
The method above can also be used in the enterprise for continuous work. The spare battery and the battery within the
Forklift can be used alternatively, charging the spare battery outside while the Forklift battery is being used.
The Motor
The driving motor and the lifting motor are all direct current dynamos that make up of stator and rotor. The
commutators on rotor conduct electricity by friction with the carbon brash, so carbon or copper powders
are produced when used for a long time. Suggest that you blow clean compressed air onto the commutator
to remove any dust and the carbon or copper powder after a period of time. At the same time, inspect and
check the roughness of the commutators and the protrusions between the blades.
If there are any spots of rust on the commutator, clean the armature with fine grain emery paper. If there
are obvious signs of abrasion or scratches on the commutator and the mica between the blades have come
to the surface, rotor must be taken out and re-machined on the lathe and scrape its entire surface to lower
the mica. This process needs to be done by an expert personnel with appropriate tools to lower the mica, to
deburr the corners of the blades and smooth the commutator.
Inspect and check periodically to ensure they are evenly worn out without any signs of abrasion or scratch

es and the brushes are free inside their housing. When replacing the brushes, follow the instructions of the
“Parts Catalog”. After replacement, attach the brushes so that they adhere completely to the commutator.

If the motor of the Forklift makes an unusual noise when operating, you should inspect and replace the
bearings.
