(can smell “hot” but not “burnt”) or rubbing
between fingers (should feel viscous and free
of any rough feel due to particles) If the
hydraulic oil passes all of the above
inspections, continue the scheduled
maintenance intervals. If the hydraulic oil
fails any of the above inspections, the
hydraulic oil must be tested by an oil
distributor or replaced.
Note: If the hydraulic oil has not been replaced for
two years, the oil must be tested every quarter by
an oil distributor until the oil fails the test and is
replaced. After the oil has been replaced,
continue the scheduled monthly maintenance

Inspection of ventilation system of hydraulic
oil tank cover
This check shall be made once per 25h or per
month, whichever is shorter.
1) The well-ventilated hydraulic oil tank cover is
essential to the good mechanical property
and service life. The dirty or blocked exhaust
cover may degrade the machine
performance. The frequent inspection is the
must for the poor working environment.
①
Remove the exhaust cover from the
hydraulic oil tank cover.
②
Check ventilation
Result: The air can pass through the exhaust
cover.
Result: If the air is unable to pass through the
exhaust cover, clean or replace the exhaust

Inspection of chassis tray locking component
This check shall be made once per 25h or per
month, whichever is shorter.
1) The good conditions of chassis tray locking
component are essential to the equipment
performance and service life. The tray may
be unexpectedly opened and the safety
hazard can be caused by the damaged
chassis tray locking component. Check the
abrasion and damage of each chassis tray
locking component.
