Periodic replacement of essential maintenance parts
In order secure safety for work and travel, conduct inspection and services.
Further, for enhanced safety, following parts and components should be replaced periodically.
These parts are prone to material deterioration due to aging or physical change due to
friction, it is difficult to determine their useful limit by regular inspection, which makes it
necessary to replace with new ones after certain period of service to ensure they function as
intended.
If any defects are detected such as crack, deformation or oil leakage, go ahead and replace
them even if it is within scheduled replacement time.

3 PERIODIC MAINTENANCE
3.1 Precautions
Whether or not the inspection service and lubrication are performed at the correct regular
intervals exerts significant influence on the occurrence of problems and service life of the
machine. In this manual, typical intervals for inspection and service are given. However,
flexibility should be exercised as to interval or type of services to enable your machine to
always operate in the best condition.
IMPORTANT
• After maintenance and inspection record the result of inspection. Remember that
replacement of filter elements, replenishment and change of oil and grease, and
cleaning the radiator fines are important.
When draining a hot oil, use care not to get burned.
• The disposal of waste oil and coolant, and used filters, elements, etc., should be
handled by specialized disposal companies.
WARNING
Be sure to take adequate care not to burn yourself when replacing filters, elements,
oil, etc.
General precautions
1) Always use SAKAI genuine parts for replacement.
2) Use lubricants recommended by SAKAI. Avoid mixing different brand lubricants.
3) For hydraulic oil replenishment, changing, level checking, filter cleaning or replacement,
oiling and greasing, use extreme care to prevent dust from entering.
4) For checking oil level or changing oil, park the machine on a level and hard surface.
5) Change oil while warm.
6) For a long-term storage, fill the fuel tank, lubricate necessary points and run the machine
for more than 20 minutes once a month.
7) In freezing weather, add antifreeze to the coolant according to the ambient temperature.
8) For the hydraulic pump and motor, have them serviced at authorized service shops.
9) Turn the starter switch OFF when performing services such as repairing broken wires,
short circuits and tightening loose terminals.
