Checking the Tire Pressure

For Machines with Pneumatic
Tires Only
Service Interval: Every 50 hours/Monthly (whichever
comes first) For machines with
pneumatic tires only.
Maintain the air pressure in the caster tires and rear
tires at 90 kPa (13 psi). Uneven tire pressure can
cause uneven cut. Check the tires when they are cold
to get the most accurate pressure reading.

WARNING
g001055
Relying solely on mechanical or
hydraulic jacks to support a raised
machine for service or maintenance
could be dangerous because the jacks
may not provide enough support or may
malfunction, allowing the machine to fall
and possibly cause serious injury.
Do not rely solely on mechanical
or hydraulic jacks for support. Use
adequate jack stands or equivalent
support.
5. Engage and disengage the parking brake and
check each drive tire to ensure that each brake
engages and disengages.
