GENERAL INFORMATION
TRANSPORTING THE MACHINE
CAUTION!
Before transporting the machine on an open truck or trailer, make sure that . . .
• All access doors are latched securely.
• The machine is tied down securely - see tie-down locations (26) .
• The machine parking brake is set.
TOWING OR PUSHING A DISABLED MACHINE
CAUTION!
The machine’s drive propelling pump is manufactured with an adjustable tow valve. This valve prevents damage to the hydraulic system when the
machine is being towed/pushed short distances without use of the engine.
To access the valve; unlatch and open the Oil Reservoir / Fuel Tank Cover
(20) and then open the Engine Compartment Cover (1) and locate the
hydrostatic pump at the rear of the engine. Turn the valve 90 degrees, this disengages the hydrostatic lock between the motor and pump.
WARNING: The hydraulic propelling pump can be damaged if the machine is towed with the valve in the normal working position
(A) . Reference
the illustration on the following page for the normal working setting (A) (vertical) and the free wheeling towing setting (B) (horizontal). Note: If the
tow valve is left in free wheeling (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: Tow or push machine no faster than a normal walking pace (2-3 miles per hour)
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.
