Pushing the Machine by Hand
Important
Always push the machine by hand. Never
tow the machine because hydraulic damage may occur.
Pushing the Machine
1.
Disengage the power take off (PTO) and turn the
ignition key to off.
2.
Rotate pump by-pass valves counterclockwise 2 turns.
This allows hydraulic fluid to by-pass the pump
enabling the wheels to turn freely (Fig. 21).
Important
Rotate by-pass valve a maximum of 2 turns
so the valve does not come out of the body causing fluid
to run out.
3.
Release the parking brake.
4.
Push the machine.
Operating the Machine
1.
Turn the by-pass valves clockwise until they are tight.
Do not over tighten (Fig. 21).
Note:
The machine will not drive unless by-pass valves
are turned in completely.
