for full forward speed. The pedal should rest on the
foot plate when the pump is stroked in the full

jam nut (See Figure 6). Place the foot control pedal
forward against the foot rest and adjust the ball joint
on the rod until the stud aligns with the hole in the
arm. Bolt the ball joint to the arm and tighten the
jam nut.
