Check Tines

Service Interval: Before each use or daily
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Lift the rear of the unit and support using jack
stands or equivalent support.
CAUTION
Raising the unit 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 unit 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 and retain the two bolts from the rear
cover panel.
4. Remove rocks and other debris from the tines.
5. Inspect the tines and replace as required.
Check Safety Interlock
System
Service Interval: Before each use or daily
CAUTION
If safety interlock switches are disconnected
or damaged the machine could operate
unexpectedly causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches
before operating the machine.
Understanding the Safety Interlock System
The safety interlock system is designed to prevent
the engine from starting unless the parking brake is
engaged.
Checking the Safety Interlock System
1. Disconnect the spark plug wires.
2. While on level ground, block the wheels of the
machine to prevent unintended movement.
3. Disengage the parking brake.
4. With the motion control levers in the neutral
position turn the key to the start position – the
starter must not crank.
Note: If the machine does not pass this test, do not
operate. Contact your authorized Exmark Service
Dealer.
