MAINTENANCE
Every 1000 Hours
1. Open the left side cover and the engine
hood.
2. Gradually loosen the radiator cap (3)
to release the internal pressure, then
remove.
3. Place a pan for catching 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 (194°F), 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.
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 (194°F) before cleaning.
