Using Pump Bypass Valves

When the bypass valve is open, the machine will have unrestricted motion.

• Do not open the bypass valve when the machine is stopped on an incline to prevent it from going downhill out of control.

Transmission damage may occur if the machine is towed or moved incorrectly:

• Move machine by hand only.
• Do not use another vehicle to move machine.
• Do not tow machine.

The pump bypass valves must be turned fully clockwise (closed) during normal machine operation.

When the machine needs to be moved without starting the engine, use the pump bypass valves:

1. Lock park brake.

2. The pumps (A) are located at the rear of the engine. The bypass valves (B) are on the forward sides of the pumps and can be accessed by lifting the thigh pad.

3. Unlock park brake.

4. Push machine to desired location. Due to hydraulic system drag, machine will move slowly.

5. Lock park brake.

6. Turn pump bypass valves (B) on both pumps 1/2 turn counterclockwise (closed position). Tighten valves to specification.
