PREVENTIVE MAINTENANCE
HYDRAULIC SYSTEM SERVICE
(See accompanying Hydraulic System Illustration)
Proper maintenance of the hydraulic components is of
vital importance to the service life of the system and
the operation of the unit as a whole.
CHECKING FLUID LEVEL (DAILY)
Place the carrier and packer panels in the “interrupted
cycle” position and fully retract the pushout cylinder to
check the fluid level. (1) When checking the fluid level
in the hydraulic tank, also note any frequent or sudden
loss of fluid. This may indicate leakage, which must be
traced and corrected to avert equipment failure and
possible damage to other components.
If low, fill the hydraulic tank to the “NORMAL FILL
LEVEL” with hydraulic fluid as specified in Sec. 4 SPECI-
FICATIONS according to operating and weather condi-
tions.
CLEAN TANK BREATHER (WEEKLY)
Clean the air breather (2) every week. Replace a
breather that cannot be cleaned adequately.
CHECK / REPLACE RETURN LINE FILTER
ELEMENT
The return line filter is a vital component of the hydrau-
lic system. Without proper filtration problems are bound
to occur among the hydraulic system components. Stick
to the strict maintenance schedule for this item.
Time Lapse Recommendations for Element Replace-
ment
After the first five days of unit operation.
After the first calender month of unit operation.
Thereafter, every twelve calender months or sooner,
if so indicated by the filter replacement indicator
(3).

3.
The condition of the filter element must be checked
weekly by looking at the visual indicator on the filter.
Refer to item 3 on the tank illustration.
NOTE
Under severe operating conditions the filter life may be re-
duced. Replace the filter element regardless of elapsed time
if the suction indicator is in the red zone.
REPLACEMENT OF FILTER ELEMENT
(See Hydraulic System Illustration)
Remove filter cover (4).
Remove o-ring (5).
Remove element (6) and discard.
Install a new element (6).
Coat a new o-ring (5) with fresh hydraulic fluid and
install in filter cover (4).
Install the cover and secure to the bowl with the
attaching hardware.
Check the fluid level and replenish with fresh fluid
as described earlier in this section under CHECK-
ING FLUID LEVEL.

Extended operation of the unit without proper fil-
tration will result in reduced service life of hydrau-
lic system components.
FLUSHING HYDRAULIC SYSTEM / CLEAN-
ING HYDRAULIC STRAINER (YEARLY)
Drain all fluid from the hydraulic tank into a suitable
container. Dispose of it properly.
Unscrew and remove strainer (7).
Clean strainer thoroughly in a suitable cleaning sol-
vent.
Wipe off the magnetic ring (8) and wipe out the
bottom of the tank.
Reinstall the strainer (7).
Fill the hydraulic tank with fresh fluid as specified
in sec. 5, SPECIFICATIONS, according to operat-
ing and weather conditions.
Start the unit and operate all hydraulic levers as
described in Sec. 3, OPERATION. Leave all hy-
draulic cylinders in the retracted position and shut
down unit.
Recheck the fluid level and add fluid as necessary
to bring level to the “NORMAL FILL LEVEL” on the
sight gauge.
