Hopper Safety Support, Jacking the Machine

A-6 / ENGLISH

HOPPER SAFETY SUPPORT

WARNING!

Make sure the Hopper Safety Support (5) is in place whenever attempting to do any maintenance work under or near the raised hopper. 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 (8).

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 Engine Compartment Cover (1) and locate the hydrostatic pump at the rear of the engine. The top half the illustration on the following page shows the location on 3 cylinder models and the bottom half shows the 4 cylinder model location. 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.
