Tine Maintenance
Checking the Tines
Service Interval: Before each use or daily
1. Shut off the engine, engage the parking brake,
remove the key, and wait for all moving parts to
stop before leaving the operating position.
2. Raise the machine and support it with jack
stands with a 460 kg (1,015 lb) capacity.
CAUTION
Raising the machine for service
or maintenance relying solely on
mechanical or hydraulic jacks could be
dangerous. The mechanical or hydraulic
jacks may not be enough support or may
malfunction allowing the machine to fall,
which could cause injury.
Do not rely solely on mechanical
or hydraulic jacks for support. Use
adequate jack stands or equivalent
support.
3. Remove the 2 bolt (3/8 x 1 inch) and 2 washers
(3/8 inch) that secure the rear-cover panel to the
chassis, and remove the panel (
