MACHINE JACKING

You can jack up the machine for service at the
designated locations. Use a jack of adequate
capacity and good working condition. Always stop
the machine on a flat, level surface and block the
tires before jacking the machine up.

The front jacking locations are on the flat bottom
edge of the front of the machine frame next to the
front tires.

The rear jacking location is the middle flat bottom
edge of the rear bumper between the taillights.

FOR SAFETY: When Servicing Machine,
Block Machine Tires Before Jacking
Machine Up.

FOR SAFETY: When Servicing Machine,
Jack Machine Up At Designated
Locations Only. Block Machine Up With
Jack Stands.

STORING MACHINE

Before storing the machine for an extended period
of time, the machine needs to be prepped to
lessen the chance of rust, sludge, and other
undesirable deposits from forming. Contact
TENNANT service personnel.
