HOPPER SAFETY SUPPORT
WARNING!
MakesuretheHopperSafetySupport(5)isinplacewheneverattemptingtodoanymaintenanceworkunderorneartheraisedhopper.
The Hopper Safety Support (5) holds the hopper in the raised position to allow work to be performed under the hopper. NEVER rely
on the machine’s hydraulic components to safely support the hopper.
JACKING THE MACHINE
CAUTION!
Never work under a machine without safety stands or blocks to support the machine.
•When jacking the machine, do so at designated locations (Do Not jack on the hopper) - see jacking locations (25).
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.
•The machine parking brake is set.
TOWING OR PUSHING A DISABLED MACHINE
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 open the left front door panel and locate the valve as shown on top rear of the propelling pump. Use a pliers or 5/16” (8 mm) open end wrench
to 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 illustrations
below 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.
