Ensure that a recommended coolant is always used.
IMPORTANT: Never fill up with cold fluid while the engine
is warm. Do not use plain water as coolant.
After changing the fluid run the engine for a time and
check the level of fluid.
H6.2. Check and clean injec-
tors (41)
A3565--- 123
For the engine to produce full power the injectors must be
in perfect condition. Checking and cleaning should be
carried out by an authorized workshop.
Symptoms of dirty or defective injectors:
--- Knocking indicates a fault on one or more of the injec-
tors. Knocking can occur on a cold engine when run-
ning at idling speed. When knocking occurs at normal
working temperature this indicates that the injectors are
not functioning property.
--- Air in the fuel system can also cause knocking (disappe-
ars after the system has been bled).
--- Smokey exhaust gases are another symptom of poor
function of the injectors (can also be due to other rea-
sons,e.g.blockedaircleaner).
H6.3. Change brake fluid (42)
AH22
WARNING: Brake fluid is corrosive and
poisonous and must be handled carefully at
all times (it also corrodes the paint).
It is recommended that the brake fluid be changed every
second year or after 2000 hours of operation.
--- Empty the brake fluid reservoir, open the bleed nipples.
It is better to place hoses from the nipples into a con-
tainer, as the fluid corrodes the paint. Pump the brake
pedal until all brake fluid in the pipes and cylinders has
run out.
--- Fill the brake system with new brake fluid.
--- Bleed the brake system of air (see Checks and Adjust-
ments on page 94).
If the tractor is equipped with the trailer brake valve and /
or air pressure brakes as extra equipment, open also their
bleed nipples to drain the hoses. The brakes must also be
bleeded from the nipples:
--- the fluid brakes of the trailer, see the bleeding instructi-
ons on page 122.
--- the air pressure brakes, see the bleeding instructions on
page 120.
The correct amount of brake fluid is 0.3 liter.
