TOWING OR PUSHING A DISABLED MACHINE
GENERAL INFORMATION
The machine’s drive propelling pump is manufactured with an
adjustabletowvalve. Thisvalvepreventsdamagetothehydraulic
systemwhen the machine is being towed/pushed short distances
without use of the engine.
To access the valve open the left front door panel and locate the
valve as shown on top front of the propelling pump. Use a pliers
or a 5/16” (8 mm) open end wrench to turn the valve 90 degrees,
this disengages the hydrostatic lock between the motor and
pump.
CAUTION!
The hydraulic propelling pump can be damaged if the ma-
chine is towed with the valve in the normal working position
(A).
Referencetheillustrations belowforthenormal working setting(A)
(vertical) and the free wheeling towing setting (B) (horizontal).
Note: Ifthetowvalveisleftinfreewheeling(B)(horizontal)position
the propelling pump can’t drive the machine FWD or REV. No
damage will result, just re-set valve to the normal working setting
(A)(vertical). NOTE:Towor push machine nofasterthananormal
walking pace (2-3 mph - 3-5 km/h) and for short distances only. If
the machine is to be moved long distances the drive wheel needs
to be raised off the floor and placed on a suitable transport dolly.
