Warning Horn
This horn will sound when the ignition is turned
ON, but should go off after the engine is started. If
the horn fails to sound when the ignition switch is
turned ON, it could indicate a horn failure. If the
horn sounds during engine operation, stop the
engine immediately and correct the source of the
problem before further engine operation.
IMPORTANT: Continued operation of the engine
with a low oil pressure condition WILL cause
severe engine damage.

Transaxle Lockout Arms

The transaxle lockout arms disengage the transax-
les. By lifting the arms up and locking them into
place with the shoulder on the arm in the chassis
notch, the transaxles are released to permit free-
wheeling. By releasing the arms and recessing
them back toward the chassis, the transaxles are
engaged for normal operation. The transaxle arms
in the LOCKOUT position are used to enable
moving the machine without the engine running
(e.g., for service). Refer to Transaxle Lockout on
page 36 for operating instructions.

in the engine performance. When this light illumi-
nates during operation, contact an authorized
