MAINTENANCE PROCEDURES
C-5 Replace Air filter of Hydraulic Tank
Keeping the breather cap of hydraulic tank in well-
ventilated condition is vital to normal operation of
hydraulic pump and extending service life. Dirty or
blocked air filter of hydraulic tank may cause the
hydraulic pump to suction improperly, and continued
operation may result in component damage. The air
filter of hydraulic tank should be inspected more often
in hostile operating environment.
1. Using a wrench, remove the air filter of hydraulic
tank（located as shown inFig 5-21 , page 5-20）.
2. Install and tighten the new filter.
C-6 Inspect Weighing System
Before the test, move the boom fully up and down and
telescope in and out for at least twice to ensure the
pulley and track are adequately lubricated.
