hen checking the steering system, don’t disassembly the steering unit readily,
if the steering unit is in trouble, please ask professional service men to repair it.

paint on the connection surface, it must be washed with acetone. You can’t wash the
parties with cotton yarn or cloth, but with brush, even clear away with compress air if
possible. Shouldn’t immerse the rubber in the gasoline for a long time. After assembling
the steering, join 50-100ml pressure oil in the orifice, turn the valve bore to right and left,
then install and practice the truck if they are not abnormal.

cover must be kept clean, and they can’t be hurt.
c. Notice that the whorl cover most be lower than the surface of the valve body.
d. Block ring and slip ring have an inverse surface, the surface of block ring should
face the front cover, while the slip ring faces the valve bore.
e. There is mark on the surface of the rotor and interlock shaft, the mark must be
face to face when assembling.
f. The gasket of the bolt (with pin) must be cuprum or aluminum.

order, not in turn but gradually, with the power of 30-40N.m.
