RT75 Rough Terrain Crane
05 - 7
( ( c c ) ) Low engine coolant:
Use soft water, e. g. tap water, for coolant. Do not use hard water (river
water).
1 Do not add a large quantity of cold water too quickly. When it is
necessary to add cold water, put the water in slowly. Follow the below
instructions to add coolant:


Put together water, antifreeze and/or anti-rust fluid in the correct
ratio.


Loosen the cap to the coolant tank with a wet rag to release the
pressure in the tank. After you release the pressure, continue to
remove the cap. The fluid released is hot and pressurized and can
cause burns or blindness. Always keep your face away from the cap
on the coolant tank.


Add the water mix to the applicable coolant tank fill-line and then
install the cap.
Do not operate the engine continuously at high speeds without a load.

( ( 8 8 ) ) Know the below data while you steer the crane:
 When you go into a corner, put the transmission in a lower gear and apply a
small quantity of pressure on the brakes.
 The steering wheel has a mechanical limit. Do not continue to turn the wheel
when at the limit. Do not keep the wheel at the limit for long periods of time.
