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 Bunton 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/in2(1.0 kg/cm2). 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.

LUBRICATION
Every 50 hours of operation, lubricate the following points (1-5) with grease:
1. Brake lever pivot (1 point)
2. Push arms (2 points located at rear of cutterdeck under each fuel tank)
3. Deck idler pivot bearings (2 points)
4. Deck lift pivots (6 points)
5. Hydro belt tensioner (1 point under engine deck)
6. Caster wheel pivots (2 points)
(Lubricate every 500 hours or once a year)
NOTE ON BLADE SPINDLES -The blade spindles on these machines use
a superior sealed bearing that does not require relubrication.

MAINTENANCE
HYDRAULIC SYSTEM
After the first 5 hours of operation, fluid level in the
hydraulic system should be checked every 100 hours
or when a leak has occurred. If the fluid is low, check
all components for leaks.
To check, remove reservoir cap M. The fluid level
should be at the bottom of the filler tube. If low, top up
(do not overfill). Use one of the oils listed below:
– SAE 15W40 motor oil
– SAE 20W50 motor oil
– 15W50 synthetic motor oil
AFTER FIRST FIVE (5) HOURS
1. Remove plug Nto drain hydraulic reservoir.
Dispose of used oil in accordance with local
requirements.
2. Clean and replace the plug.
3. Change hydraulic oil filter G.
4. Fill the reservoir with fresh oil to the bottom of the
reservoir filler tube, using an oil from the list
above. Do not overfill.
PERIODIC OIL CHANGES
Change the hydraulic fluid and hydraulic filter after
each 500 hours of operation using the same
procedure given above.
NOTES:
Before servicing the hydraulic system, stop the engine, disconnect spark plug wires and disengage the PTO.
– After any hydraulic line is opened, plug or cap it promptly to reduce the risk of contamination.
– Do not use teflon tape on hydraulic pipe fittings. Use a liquid sealant that will dissolve into the system.
– Make sure all hydraulic connections are tight and hydraulic hoses and lines are in good condition before
applying pressure to system.
The machine's hydraulic system operates under high pressure. When checking for leaks, do not use your
hands to attempt to find a leak. Instead, use cardboard or paper. Escaping hydraulic fluid can be under
sufficient pressure to penetrate skin and cause serious injury. If hydraulic fluid is injected into the skin, it must
be promptly removed by a doctor familiar with this form of injury or gangrene may result.

SPARK PLUGS
Remove each plug and check condition.
– Good operating conditions are indicated if the plug has a light coating of grey or tan deposit.
– A white blistered coating indicates overheating. A black coating indicates an “over rich” fuel mixture. Both
may be caused by a clogged air cleaner or improper carburetor adjustment.
– Do not sandblast, wire brush or otherwise attempt to repair a plug in poor condition. Best results are
obtained with a new plug.
– Set plug gap as specified in engine manual.
MAINTENANCE
ENGINE OIL
Do not perform engine maintenance without the
engine off, spark plug wires disconnected and PTO
disengaged.
AFTER FIRST FIVE (5) HOURS
While the engine is warm:
1. Remove drain cap Dand drain the crankcase.
