• Loosening or loss of bolts
• Damage to parts

(4) Checking and Re-supplying Cooling
Water
Burns from Scalding
������
• Never remove the filler cap of the fresh
water cooler while the engine is still hot.
Steam and hot water will spurt out and
seriously burn you. Wait until the water
temperature has dropped, then wrap a
cloth around the cap and loosen it slowly.
• After inspection, refasten the filler cap firmly. If the
������
cap is not secure, steam or scalding water may be
emitted during operation causing burns.
1 Check the cooling water level in the sub-tank.
If the water level is close to the lower limit, remove
the sub-tank cap and fill with fresh water to the
upper limit.
2 When the water level in the sub-tank is low, remove
the filler cap of the fresh water tank and check the
amount of cooling water in the fresh water tank. If
the level is low, fill with fresh water until it overflows.
See 3.4

See 3.3 • Check the fresh water level, before operation, while

the engine is cold. Checking the water level while
the engine is hot is dangerous and the cooling
water reading will be misleading due to thermal
expansion.
• Check and supply cooling water daily to the
sub-tank. Do not remove the fresh water filler cap
regularly.
• The amount of water in the sub-tank will increase
