MAINTENANCE
CHECK DAILY
Operator Presence Interlock System - Start Operation
For the engine to crank, the parking brake must be on, the PTO (blades) off and traction levers in the neutral
lock position. Sit in the seat and check, one by one, if the engine will crank with the parking brake off, the
blades on, and either traction lever out of neutral lock. Also, make sure engine coolant temperature gauge
light flashes upon turning key to the ON position.
Operator Presence Interlock System - Run Operation
The operator must be in the seat for the engine to run with the parking brake off, the traction levers moved out
of the neutral lock position, or the blades on. To check:
1. Start the engine and run at 1/2 throttle with the operator on the machine but raised off the seat.
2. One by one: move the parking brake to the “OFF” position, traction levers out of the neutral lock position
(check each independently), and turn the blades on. Each check should kill the engine after 1/2 second.
(A 1/2 second delay is built into the system to prevent engine cutout when traversing rough terrain.)
Repair machine before using if the Operator Presence Interlock System does not operate correctly in start or
run. Contact your authorized Jacobsen dealer.
Hardware
Tighten any nuts and bolts found loose. Replace any broken or missing cotter pins. Repair any other problems
before operating.
Tire pressure
Tires should be kept inflated at 14 lbs/in
2
(1.0 kg/cm
2
). Improper tire inflation can cause rapid tire wear and
poor traction. Uneven inflation can cause uneven cutting.
Battery
Battery acid is caustic and fumes
are explosive and can cause serious injury or death.
Use insulated tools, wear protective glasses or
goggles and protective clothing when working with
batteries. Read and obey the battery manufacturer’s
instructions.
Be certain the ignition switch is “OFF” and the key
has been removed before servicing the battery.
1. Verify battery polarity before connecting or
disconnecting the battery cables.
2. When installing the battery, always assemble the
RED, positive ( + ) battery cable first and the
ground, BLACK, negative ( - ) cable last.
3. When removing the battery, always remove the
ground, negative ( - ) cable first and the red,
positive ( + ) cable last.
4. Check the electrolyte level every 100 hours of
operation.
5. Clean the cable ends and battery posts with steel
wool. Use a solution of baking soda and water to
clean the battery. Do not allow the solution to
enter into the battery cells.
6. Tighten cables securely to battery terminals and
apply a light coat of silicone dielectric grease to
terminals and cable ends to prevent corrosion.
Keep terminal covers in place.
