Pushing the Machine by Hand
The by–pass valve also allows the machine to be
pushed by hand with the engine not running for easier
servicing. If the by–pass valve is opened to push the
machine by hand, adjustment is required for
operation.
IMPORTANT: Always push the machine by
hand. Never tow the machine because
hydraulic damage may occur.
To Push the Machine
1. Disengage the power take off (PTO) and turn the
ignition key to “OFF” to stop the engine.
2. Loosen jam nuts and rotate by-pass valves open
5 turns to push. This allows hydraulic fluid to
by-pass the pump and the wheels to turn
(Fig. 13).
IMPORTANT: Rotate by-pass valve a
maximum of 5 turns so the valve does not
come out of the body causing fluid to run out.
To Operate the Machine
If the by–pass valve is opened to push the machine by
hand, adjustment is required for operation. Refer to:
“Adjusting By-pass Valve”.
Note: The machine will not drive unless
by-pass valves are properly adjusted.
