battery first and then disconnect the opposite end from the
booster battery.

WARNING
Any procedure other than the preceding could result in:
(a) personal injury caused by electrolyte squirting out the
battery vents,
(b) personal injury or property damage due to battery
explosion,
(c) damage to the charging system of the booster vehicle or
of the immobilized vehicle.
Do not attempt to jump start a vehicle having a frozen battery
because the battery may rupture or explode. If a frozen battery
is suspected, examine all fill vents on the battery. If ice can
be seen or if the electrolyte fluid cannot be seen, do not
attempt to start with jumper cables as long as the battery
remains frozen.

Troubleshooting

While normal care and regular maintenance will extend the life
of your equipment, prolonged or constant use may eventually
require that service be performed to allow it to continue to
operating properly.
This troubleshooting guide lists the most common problems,
their causes and remedies.
Refer to Maintenance Procedures for instructions on how to
perform most of these minor adjustments and service repairs
yourself. If you prefer, all of these procedures can be performed
for you by your local authorized dealer.
WARNING
Remove ignition key prior to performing maintenance on the
unit.
To avoid serious injury, perform maintenance on the unit or
mower deck only when the engine is stopped and the parking
brake is engaged.
Always remove the ignition key, disconnect the spark plug
wire(s) and fasten it away from the plug(s) before beginning
the maintenance, to prevent accidental starting of the engine.
