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.
•Whenjackingthe machine,do so atdesignated locations (DoNot jackonthe hopper)-see jackinglocations (25).
TRANSPORTING THE MACHINE
CAUTION!
Before transporting the machine on an open truck or trailer, make sure that...
•Allaccess doorsarelatched securely
•The machine is tied down securely.
•Themachineparking brakeisset.
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
machineisbeingtowed/pushedshortdistanceswithoutuseoftheengine.
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
theillustrationsbelow forthe normalworkingsetting (A)(vertical) andthefree wheelingtowing setting(B)(horizontal). Note: If thetow valveisleft
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.
