Check Battery Charge
Service Interval:
Monthly
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 V.
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.
1.
Check the voltage of the battery with a digital
voltmeter or with the message display. If the
voltage is less than 12.4 V, the battery may need
to be charged.
Important:
In order to prevent damage to
the battery, use an automatic 12 volt smart
charger approved for use with AGM type
batteries with an output of 3.5 amps or less.
Toro recommends the use of battery charger
P/N 135-7024. Make sure the negative battery
cable is disconnected before charging and
that the charger is set to the correct mode
for 12 V AGM batteries.
2.
Connect the negative battery cable.
Note:
If the positive cable is also disconnected,
connect the
positive (red) cable
to the positive
battery terminal
first
, then the negative (black)
cable to the negative battery terminal. Slip
insulator boot over the positive terminal.
Note:
If time does not permit charging the
battery, or if charging equipment is not available,
connect the negative battery cables and run
the vehicle continuously for 20 to 30 minutes to
sufficiently charge the battery.
Recommended Jump
Starting Procedure
1.
Check the weak battery for terminal corrosion
(white, green, or blue “snow”), it must be cleaned
off prior to jump starting. Clean and tighten
connections as necessary.
CAUTION
Corrosion or loose connections can
cause unwanted electrical voltage spikes
at anytime during the jump starting
procedure.
Do not attempt to jump start with loose
or corroded battery terminals or damage
to the engine may occur.
