Maintenance
battery performance and life, recharge batteries in
storage when the open circuit voltage drops to 12.4
volts.
Note:
To prevent damage due to freezing, battery
should be fully charged before putting away for
winter storage.
Check the voltage of the battery with a digital
voltmeter. Locate the voltage reading of the battery in
the table and charge the battery for the recommended
time interval to bring the charge up to a full charge
of 12.6 volts or greater.
Important:
Make sure the negative battery
cables are disconnected and the battery charger
used for charging the battery has an output of
16 volts and 7 amps or less to avoid damaging
the battery (see chart for recommended charger
settings).

Check Safety Interlock
System
Service Interval: Before each use or daily
Note:
To prevent engine cut-outs on rough terrain
the seat kill switch has a 1/2 second delay.
1. Check starting circuit. Starter
should
crank with,
parking brake
engaged
, PTO
disengaged
and
motion control levers moved out in the
neutral
lock
position. The operator does not need to be
in the seat to start the engine.
Try to start with
operator in seat
, parking brake
disengaged, PTO disengaged and motion control
levers in the
neutral lock
position - starter
must
not crank
.
Try to start with
operator in seat
, parking brake
engaged, PTO
engaged
and motion control
levers in the
neutral lock
position - starter
must
not crank
.
Try to start with
operator in seat
, parking
brake
engaged
, PTO
disengaged
,
and the left
motion control lever in
, starter
must not crank
,
repeat again with the
right lever in
, then with
both levers in
- starter
must not crank
.
2. Check the kill circuits. Run engine at one-third
throttle,
disengage
parking brake and
raise off
of seat (but do not get off of machine) engine
must initiate shutdown
after approximately 1/2
second has elapsed (seat has time delay kill switch
to prevent cut-outs on rough terrain).
Run engine at one-third throttle,
engage PTO
and
raise off
of seat (but do not get off of
machine) engine
must initiate shutdown
after
1/2 second has elapsed.
Run engine at one-third throttle, with brake
disengaged, move levers in and raise off seat (but
do not get off of machine) engine must
initiate
shutdown
after 1/2 second has elapsed.
Again, run engine at one-third throttle, brake
engaged
, and move
left motion control lever in
- engine
must initiate shutdown.
Repeat again moving the
right lever in
, then
moving
both levers in
- engine
must initiate
shutdown
whether operator is
on seat or not
.
3. Check the PTO circuit. See the FR524, FR604,
and FR724 Operator’s manual to become familiar
with the deck operation. Open the folding
deck latches,
disengage
the park brake, move
the motion control levers in to
neutral
, and
disengage
the PTO.
Lower
the deck until the
PTO switch arm is no longer depressing the PTO
“kill” switch (see Figure 9).
