MAINTENANCE
Every 1000 Hours
1. Open the engine hood.
2. Gradually loosen the radiator cap (3) to
release the internal pressure, then remove
the cap.
3. Place a pan to catch the spent coolant
under the drain plug (4), then loosen the
drain plug (4) and drain the coolant.
4. Tighten the drain plug (4).
5. Add tap water through the radiator’s
coolant supply port up to the top of the
port. Take your time doing this, adding the
water slowly to avoid any air from entering
the radiator.
6. Close the radiator cap (3).
7. Start the engine and run it at a speed
slightly above low idling. Raise the water
temperature to at least 90
°
C, then run the
engine for about 10 minutes with the
thermostat open.
8. Stop the engine, let the water’s
temperature lower, then loosen the drain
plug (4) and drain the water.
9. After draining the water, clean using
cleaning agent. Clean following the
instructions included with the cleaning
agent you are using.
Cleaning the Engine Cooling
System
WARNING
¡ ¡
¡ ¡
¡
Stop the engine and allow the machine
to cool down before performing
maintenance.
• The engine, muffler, radiator and
many other parts of the machine are
hot directly after the engine is
stopped. Touching these parts will
cause burns.
• The engine coolant is also hot and
under high pressure. Be careful
when loosening caps and plugs.
Working on the machine under these
conditions could result in burns or
injuries due to the hot coolant
spurting out.
¡ ¡
¡ ¡
¡
If maintenance must be performed with
the engine running, always work as a
two-person team with one person
sitting in the operator’s seat while the
other works on the machine.
• When performing maintenance, be
sure to keep your body and clothing
away from moving parts.
¡ ¡
¡ ¡
¡
Standing at the back of the machine
while the engine is running is extremely
dangerous, as the machine could move
suddenly. Never stand at the back of
the machine while the engine is
running.
¡ ¡ ¡ ¡ ¡
Do not remove the radiator cap or drain
plugs when the coolant is hot. Stop the
engine, let the engine and radiator cool
and loosen the radiator cap or drain
plugs slowly.
When cleaning, if the temperature of the
coolant is low, the thermostat will be closed
and the coolant will not circulate in the
radiator. Heat the coolant water to at least
90
°
C before cleaning.
