MACHINE JACKING

Empty the hopper before jacking machine. You

can jack up the machine for service at the

designated locations. Use a jack or hoist that will

support the weight of the machine. Always stop

the machine on a flat, level surface and block the

tires before jacking up the machine.

FOR SAFETY: Before leaving or

servicing machine, stop on level

surface, set parking brake, turn off

machine, and remove key.

The front jacking locations are on the flat bottom

edge of the front of the machine frame.

FOR SAFETY: When servicing machine,

block machine tires before jacking up

machine.

The rear jacking locations are on the corners of

the rear frame.

FOR SAFETY: When servicing machine,

block machine tires before jacking up

machine.

FOR SAFETY: When servicing machine,

jack up machine at designated locations

only. Block machine up with jack

stands.

STORING MACHINE

Before storing the machine for an extended time,

the machine needs to be serviced to lessen the

chance of rust, sludge, and other undesirable

deposits from forming.

Drain the dust control system water tank before

storing the machine to prevent water from

freezing. See the DRAINING THE WATER TANK

section in the MAINTENANCE section of the

manual.
