Disconnect battery ground cable (−) before making
adjustments to electrical systems or before welding on
the machine.
Sufficiently illuminate the work site. Use a
maintenance work light when working under or inside
the machine.
Always use a work light protected with a guard. In
case the light bulb is broken, spilled fuel, oil, antifreeze
fluid, or window washer fluid may catch fire.
When the floor tilt mechanism check and/or mainte-
nance is conducted, the operator's station is tilted
upward. Before conducting maintenance work, refer to
page 7-76 in the operator's manual for the detailed
operation procedures and correctly operate the ma-
chine.
When required to work under the floor, support the
raised operator's station with the fall prevention bars
(red color) to ensure safety.
When the inspection/maintenance work is complete,
tilt the operator's station downward after housing the
fall prevention bars. Be sure to slowly lower the op-
erator's station at the time.
Be careful not to allow the operator's station to tilt
down without first stowing the fall prevention bars.
Damage to the tilt mechanism may result.

WARN OTHERS OF SERVICE WORK

Unexpected machine movement can cause serious
injury.
Before performing any work on the machine, attach a
"Do Not Operate" tag in an easy-to-see place such as
on the cab door or control lever.
Never attempt to operate the machine with a "Do Not
Operate" tag attached.
Make it a rule for the inspection/service person to hold
the engine start key during inspection/service work.
