Electrical System Safety
•
Disconnect the battery or remove the spark-plug
wire before making any repairs. Disconnect the
negative terminal first and the positive terminal
last. Connect the positive terminal first and
negative last.
•
Charge the battery in an open, well-ventilated
area, away from sparks and flames. Unplug the
charger before connecting or disconnecting the
battery. Wear protective clothing and use insulated
tools.
Checking the Battery
Charge
Allowing batteries to stand for an extended period of
time without recharging them will result in reduced
performance and service life. To preserve optimum
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.
Charge batteries in an open well ventilated area,
away from spark and flames. Unplug charger before
connecting or disconnecting from battery. Wear
protective clothing and use insulated tools.
DANGER
Charging or jump starting the battery may
produce explosive gases. Battery gases can
explode causing serious injury.
• Keep sparks, flames, or cigarettes away
from battery.
• Ventilate when charging or using battery in
an enclosed space.
• Make sure venting path of battery is always
open once battery is filled with acid.
• Always shield eyes and face from battery.
DANGER
Battery electrolyte contains sulfuric acid,
which is poisonous and can cause severe
burns. Swallowing electrolyte can be fatal or
if it touches skin can cause severe burns.
• Wear safety glasses to shield eyes, and
rubber gloves to protect skin and clothing
when handling electrolyte.
• Do not swallow electrolyte.
• In the event of an accident, flush with water
and call a doctor immediately.
CAUTION
If the ignition is in the ON position there
is potential for sparks and engagement
of components. Sparks could cause an
explosion or moving parts could accidentally
engage causing personal injury.
Be sure ignition switch is in the OFF position
before charging the battery.
Check the voltage of the battery with a digital voltmeter
or with the message display When the ignition is set
to the accessory mode, the module will display the
battery voltage. If the voltage is less than 12.4 volts,
the battery may need to be charged.
