the 8th record. Each record will be displayed
for 10 seconds. Be sure to have the Diagnostic
Tool display on Outputs to see fault. The
Problem circuit will be flashing. Records will
repeat until key is turned off. Unit will not start
in this mode.

7. Rotate ignition key to Off position.
8. Turn Backlap Switch to the Front or Rear Backlap
position.
9. Turn the Reel Control Switch to Enable position.
10. Move the Joystick to the Raise position and hold.
11. Turn the ignition key to On, and continue to hold
the Joystick in the Raise position until the Reel
Control Lamp starts to flash (approx. 2 seconds).
12. Release the Joystick and turn the Key Off. Memory

Important: The Diagnostic ACE display
must not be left connected to the machine. It
is not designed to withstand the environment
of the machine's every day use. When done
using Diagnostic ACE, disconnect it from the
machine and reconnect loopback connector to
harness connector. Machine will not operate
without loopback connector installed on
harness. Store Diagnostic ACE in dry, secure
location in shop, not on machine.

Operating Tips

Familiarization
Before mowing grass, practice operating machine in
an open area. Start and stop the engine. Operate in
forward and reverse. Lower and raise cutting units and
engage and disengage reels. When you feel familiar with
the machine, practice operating up and down slopes
at different speeds.
The brakes can be used to assist in turning the machine.
However, use them carefully, especially on soft or
wet grass conditions because the turf may be torn
accidentally. Individual turning brakes may also be used
to help maintain traction. For example, in some slope
conditions, the uphill wheel slips and loses traction. If
this situation occurs, depress uphill turn pedal gradually
and intermittently until the uphill wheel stops slipping,
thus, increasing traction on the downhill wheel.
Important: Before mowing grass, practice
operating the machine in turns. Turf damage in
turns may occur especially under soft or wet grass
conditions if the turn is completed at a high speed
or at a small turning radius. Maintain a speed
below 3 mph during a turn and a turning radius
greater than 8 feet to minimize turf damage from
tires or cutting units. Mounting the cutting units
with the steering pin in the front mounting hole will
allow the cutting unit to steer itself as the traction
unit turns providing optimum maneuverability and
cutting performance in turns. During cross-cutting
of fairways, a tear drop shape turn is recommended
to increase cutting productivity and minimize turf
damage.
When operating the machine, always use the
seat belt and ROPS together. Do not use a seat
belt without a ROPS.
Warning System
If a warning light comes on during operation, stop the
machine immediately and correct the problem before
