Tine Maintenance
Checking the Tines
Service Interval: Before each use or daily
1. Stop the engine, set 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 (
Figure 66 ).

7. Secure the cover panel to the chassis with the 2 bolts
and 2 washers (
Figure 66 ) that you removed in step 3 ,
and torque the bolts to 37 to 45 N-m (27 to 33 lb-in)
