CAUTION:
• The radiator is to retain a high water level
during cleaning with running water. Adjust
the quantities of water supplied and drained
as necessary.
• Ensure that the water filling hose stays
connected to the radiator supply port
properly during cleaning with running water.
14. Once clean water has out
flowed, stop the
engine and water supply and drain tap water.
Close the drain valve (8) upon completion of
draining.
15. Supply coolant mixed of antifreeze and tap
water to the radiator through the radiator
supply port. The radiator needs to be filled up
to the supply port.
NOTICE: See the above-mentioned table, "Mixing
ratio between water and antifreeze", for the mixing
ratio of antifreeze and tap water.
16. Start the engine with the radiator cap (5)
removed, and ensure the engine runs at low
idle for 5 minutes. Release air from the
cooling system with the engine at high idle for
5 minutes.
Fig. 5-87
17. Wait for 3 minutes after stopping the engine.
Supply tap water to the radiator through the
radiator supply port, up to the supply port.
Close the radiator cap (5).
18. Remove the reserve tank (1). Clean the
inside of the reserve tank with coolant
drained from the tank.
Fig. 5-88
19. Put the reserve tank (1) in place, supply tap
water through the supply port to "FULL".
Install the cap (2) properly.
20. See "Installing Machinery Cover" on page
5-18 and install the machinery cover.
21. See "OUTRIGGER STOWING" on page 4-45
and rotate the outriggers inward to stow
them.
Replace Oil in Hydraulic Oil Tank
WARNING!
• All the parts will be at elevated temperatures
immediately after engine operation, which
urges you not to replace oil. Always perform
replacement with the oil cold.
• Potential gush of oil may occur upon
removing the filler cap of the hydraulic oil
tank.
Be sure to relieve internal pressure by
slowly rotating the filler cap before cap
removal.
• Make sure the filler cap is closed properly
after replenishment of the oil.
Potential fall of the filler cap during
operation may occur if disregarded, which
could cause boiling oil to gush that results
in burns.
CAUTION:
• See "LUBRICATING OIL" on page 5-14 for
which oil to be used.
• Place the machine in travel position for oil
quantity inspection.
• Oil quantity inspection with the machine in
working position may deceive your eyes to
deem the quantity of oil low. Owing to
improper judgment, the oil may be supplied
at excessive amount.
• The engine must be at halt until piping and
hydraulic equipment is filled with oil after
replacement of the hydraulic oil filter.
• Oil replenished should remain below "H"
(upper limit) on the level gauge. Excessive
oil replenishment may cause the oil to gush
from the air breather during machine
travelling and crane operation, which could
result in burns.
• Keep impurities out of the filler cap when
replenishing oil.
