MAINTENANCE
Every 1000
Hours
Cleaning
the
Engine Cooling
System
AwARNING
•
Stop
the engine and
allow
the
machine
to
cool 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, because
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 to at least
90
°C
(195
°
F)
before cleaning.
1. Open the
rear
door and remove the under
cover
(5)
.
2.
Gradually loosen the radiator cap
(3)
to
release the internal pressure, then remove
the cap.
3.
Place a pan to catch the waste 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 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 coolant
temperature to at least 90°C
(195
°
F)
, then
run
the engine for about 10 minutes with
the thermostat open.
