ASSEMBLY
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 |
|---|---|---|
| 15 PSI | 18 PSI |
WARNING:
Check the tire pressure carefully while inflating. Too much air in the tire
could cause the tire to burst, causing serious personal injury.
VERIFY MOWER CONDITION
Inspect the entire product for damaged, missing, or loose parts such as
screws, nuts, bolts, caps, etc. Tighten securely all fasteners and caps and do
not operate this product until any missing or damaged parts are replaced.
DRIVE THE MOWER OFF THE FRAME
NOTE: Mower should be assembled while positioned on the frame bottom.
Once assembly is complete, raise the cutting deck to its highest position,
position a ramp next to the frame bottom, release the parking brake and slowly
and carefully drive mower off frame.
WARNING:
Use extra care when driving the mower off of the frame.
Press the low speed drive button and carefully move the joystick and/or press
the brake pedal as needed to control the speed. When driving the mower off of
the frame, do not exceed the maximum recommended operation angle of 15°.
Failure to follow these instructions can result in loss of control and result
in death, serious personal injury, or propertydamage.
NOTICE: If no ramp is available, slowly and carefully drive the mower off
the frame in reverse while looking down and behind. Driving the mower off the
frame in the forward direction without a ramp can cause damage to the mower’s
cutting deck.

Mower batteries must be fully charged before first use. To verify mower
batteries are fully charged, check the batterylevel 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.
This mower features a Safety Interlock System to protect the operator by
shutting off the blades if the operator leaves the seat with the blades
running. Test the system to be sure it is working correctly.
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.
