8.5.2 Hydraulic Oil Filter
NOTE
Change hydraulic oil filter after the first
50 hours of operation, and every 250
hours thereafter. MD #123989 can be
obtained from your MacDon Dealer.
To change hydraulic oil filter, proceed as
follows:
CAUTION
Stop engine, and remove key from ignition
before leaving Operator's seat for any
reason. A child or even a pet could engage
an idling machine.
a. Remove five screws (A), and remove panel (B).
b. Clean around mating surfaces of filter and valve
block (C).
c. Remove spin-off filter (D), and clean the
exposed filter port in valve block.
d. Apply a thin film of clean oil to the O-ring
provided with the new filter.
e. Turn filter into the valve block until O-ring
contacts mating surface. Tighten filter an
additional 1/2 to 3/4 turn by hand.
IMPORTANT
Do NOT use a filter wrench to install
filter. Over-tightening can damage
O-ring and filter.
f. Re-install panel (B) with screws (A).
8.5.3 Hoses and Lines
Check hydraulic hoses and lines daily for signs
of leaks.
WARNING
 Avoid high-pressure fluids. Escaping
fluid can penetrate the skin causing
serious injury. Relieve pressure before
disconnecting hydraulic lines. Tighten
all connections before applying
pressure. Keep hands and body away
from pin- holes and nozzles which eject
fluids under high pressure.
 If ANY fluid is injected into the skin, it
must be surgically removed within a few
hours by a doctor familiar with this type
of injury or gangrene may result.
 Use a piece of cardboard or paper to
search for leaks.
IMPORTANT
Keep hydraulic coupler tips and
connectors clean. Dust, dirt, water
and foreign material are the major
causes of hydraulic system damage.
DO NOT attempt to service
hydraulic system in the field.
Precision fits require WHITE ROOM
CARE during overhaul.
