7.13 HYDRAULIC FILTERS ______________________________________________________
The hydraulic system is protected by two 10 micron filters, a
charge filter (B) and return line filter (A). Flow though the
filters is monitored during operation. When pressure drop
across the filters is too high the hydraulic oil filter warning
light will come on. To ensure continued protection to the
hydraulic system, replace both filters as soon as possible
after light comes on.
NOTICE
During cold weather the warning light may come on until
oil has warmed up to operating temperature. Wait until oil
has warmed up and light goes out before operating
To replace hydraulic filters:
1.
Remove the old filters.
2.
Install new filters. Hand tighten only.
