tic"LED's should be lit steadily. "Alarm ON" LED may be
displayed temporarily (about 5 seconds).

connected, broken or "+" and "–" reversed.
2. Make sure TurfDefender 4–pin connector is
plugged in.

If 4 beeps are heard:
The most common cause for a 4 beep signal is from an
improper oil level reading. Make sure machine is on a
level surface when checking oil level. Since oil level will
vary with temperature, it is best to check when cool.

the following problems diagnosed by the TurfDefender:
D
Oil level low: Position machine on a level surface
and fill to proper level.
D
Oil level high: Position machine on a level sur-
face and remove excess oil until proper level is at-
tained.
