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 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.
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 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 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 in 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
Check the electrolyte level at each oil change as follows:
1. Stop engine and remove key.
2. Remove battery vent caps. The electrolyte level should reach the bottom of the vents.
3. Top up, if necessary, with distilled water.
4. Replace vent caps.
Gearboxes
Check for evidence of leaks daily. If leaks are detected, get them repaired immediately
to avoid wrecking a gearbox from lack of lubrication. The gearboxes only contain a few
ounces of lubricant, which won’t last long if there is a leak.
