Moving by Hand

IMPORTANT INFORMATION Tighten the valve moderately.

Do not overtighten the valve when closing. That can damage the valve seat.

Pump release valves

Pump release valves are located at the front and rear of the pump. They are used to release the system so the machine may be moved by hand when not running. Tilt seat forward to gain access to the pump. The rear bypass valve sits directly opposite the front valve, below the seat support. It is not visible in the illustration.

Use a 17 mm open end wrench or socket and ratchet. Turn the outer locknut 2-3 turns. Using an 8mm wrench or socket, turn the inner nut one turn.

Reverse the procedure to reset the pump.
