FINAL PREPARATION

CHECK TIRE PRESSURE
Check the air pressure in all tires before use. Improper air pressure will affect handling, steering response, traction, tire life, level cutting, and operator comfort. Be sure tires are inflated to the pressure shown below.
NOTE : Tire pressure should only be measured or adjusted when tires are cold.

Recommended Pressure Front Rear
19 PSI 18 PSI

WARNING: Check the tire pressure carefully while inflating. Too much air in the tire could cause the tire to burst, causing seri- ous personal injury

CHARGE THE MOWER

Mower batteries must be fully charged before first use. To verify mower batteries are fully charged, check the battery level indicator.

To charge:

  • Insert charger plug into charging port on mower, making sure it is properly connected.
  • Connect charger to power supply using normal household current of 120 V, AC only, 60 Hz.
  • Do not charge in an area of extreme heat or cold.
  • Remove the charger from the mower once it is fully charged and ready for use

WARNING : To avoid accidental starting or movement of the mower that could result in death or serious personal injury, always remove the start key and set the parking brake when leaving the mower unattended.
NOTICE : Always connect the mower to the charger when the unit is not in use. If it is not possible to leave the mower charger connected, make sure to charge the batteries fully at least once a month.

TEST THE SAFETY INTERLOCK SYSTEM

See Figure 10.

To test:

  • Position the mower on a level surface.
  • Set the parking brake.
  • Make sure the joystick is in the locked, neutral position and blade engage knob is down.
  • Install start key and turn to ON position.
  • Raise blade engage knob to activate blades.
  • Briefly lift off the seat, but do not get off the mower.

The blades should shut off within 5 seconds. If they don’t, verify you connected the safety interlock cable as described on page 6. If the cable is connected but the system still doesn’t function, contact customer service. Do not operate the mower until the safety interlock system has been repaired.
