reading on the pressure gauge. Note the
pressure. Refer to Section 2,

Specifications.

5 Turn the engine off. Use a wrench to hold the

steer relief valve and remove the cap (item FV).

6 Adjust the internal hex socket. Turn it clockwise

to increase the pressure or counterclockwise to
decrease the pressure. Install the relief valve
