4.11 Maintenance procedure
When required
Clean inside of cooling system
WARNING
Immediately after the engine is stopped, the coolant is at a
high temperature and the radiator is under high internal
pressure.
If the cap is removed to drain the coolant in this condition,
there is a hazard of burns. Wait for the temperature to go
down, then turn the cap slowly to release the pressure
before removing it.
Cleaning is carried out with the engine running. When stand-
ing up or leaving the operator's seat, raise the safety lock
lever to the LOCK position.
For details of starting the engine, see "Check before starting
engine (3-96)" and "Starting engine (3-112)" in the Operation
section.
There is danger of touching the fan if the undercover is left
removed.
Never enter behind the machine when the engine is running.
Clean the inside of the cooling system, change the coolant and
replace the corrosion resistor agent KI according to the table
below.
Kind of coolant
Permanent type antifreeze
(All season type)
Non permanent type antifreeze
containing ethylene glycol (win-
ter, one season type)
When not using antifreeze
Stop the machine on level ground when cleaning or changing
the coolant.
Use a permanent type of antifreeze.
If, for some reason, it is impossible to use permanent type anti-
freeze, use an antifreeze containing ethylene glycol.
Super Coolant (AF-ACL) has an anti-corrosion effect as well as
an antifreeze effect.
4-40
Cleaning inside of cooling system
and changing coolant
Every year (autumn) or every 2000
hours whichever comes first
Every 6 months (spring, autumn)
(Drain antifreeze in spring,
add antifreeze in autumn)
Every 6 months or every 1000 hours
whichever comes first
Adding corrosion resistor agent KI
