7 ADJUSTMENTS
7.1 GENERAL PRECAUTIONS ______________________________________________
A trained technician must always do the adjustments and maintenance.
Inspect the equipment according to the maintenance schedule and keep complete records.
1. Keep the equipment clean.
2. Keep all the moving parts correctly adjusted and lubricated.
3. Replace worn or damaged parts before you operate the mower.
4. Keep all fluids at the correct level.
5. Keep the guards in position and all hardware tight.
6. Keep the tyres inflated to the correct pressure.
7. Do not wear jewelry or loose fitting clothing, when you make adjustments or carry out maintenance.
Refer to the illustrations in the Parts Manual for the removal and assembly of parts.
When you discard hazardous materials (batteries, lubricants, fuel, anti-freeze), follow your local, state or federal-
recommended procedures.
7.2 TRACTION CONTROL _________________________________________________
The LPV transmission pump has a maintenance free drive limiter. If the machine does start to move slowly at idle
speed, do this maintenance.
1. Lift and safely support the vehicle with all wheels off the ground.
2. Remove the ball-joint A from pump lever B to allow the pump to
become neutral.
3. Start the engine, manually move the pump control lever and
release to make sure the wheels stop rotating.
4. Where it has been identified that the transmission pump is not
returning to neutral, adjust the mechanical neutral (F) within the
pump
(This should only be adjusted by a trained technician) .
5. Operate the foot pedal to make sure the cable is free.
6. Attach the ball joint A to pump lever B.
7. Move the foot pedal through forward and reverse to make sure there is no movement at the idle speed with
the drive in the Neutral position.
WARNING
When you clean, adjust or repair this equipment, lower all the cutting units to the ground.
Engage the parking brake switch, stop the engine and remove the key.
Make sure the mower is parked on a solid and level surface. Never work on the mower,
if the mower is only supported by the jack. Always use jack stands.
