Section 4 - General Maintenance
4.8 Hydraulic System Maintenance
The hydraulic pump operates at very high pressure
and has specific maintenance requirements. You
should perform all recommended maintenance ac-
cording to the pump manufacturers’ specifications.
Hydraulic fluid should be changed and the tank
flushed on a regular schedule in accordance with
the hydraulic component manufacture’s recom-
mendations. Hog Technologies recommends
changing the fluid at least once every 600 hours.
Daily Inspection and Maintenance
• Check the hydraulic fluid level each day or
immediately following the repair of a blown
hose, leaking fitting or any hydraulic system
service.
• Inspect all hoses, fittings, valves and seals for
leaks and proper operation. Repair or replace
leaking or malfunctioning components before
operating the system.
• Monitor the cooling fan operation. Make sure
it is running when the hydraulic system is
operating, sounds normal and pulls a strong
flow of air through the cooler.
Refer to the Maintenance Matrix in this section for
fluid specifications.
200 Hour Inspection and Maintenance
• Change the low pressure filter in the return
line. The filter removes any debris that may
enter the system and should be changed every
200 hours or more frequently if necessary.
• Inspect the cooling fins for the oil cooler and
clean as necessary. The cooler is critical in
maintaining acceptable oil temperatures in
the hydraulic system and must be kept clean
to maintain efficiency.
600 Hour Inspection and Maintenance
• Drain hydraulic fluid and flush hydraulic tank.
Changing Hydraulic Fluid
The reservoir tank must be drained and flushed at
regular intervals. Only qualified service technicians
should drain and flush the system or replace
hydraulic fluid filters.
