Jump Starting The Machine - Toro GrandStand 74583 Operator's Manual

Jump Starting the Machine

1. Check and clean corrosion from the battery terminals
before jump starting the machine. Ensure that the
connections are tight.
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 or EFI may occur.
DANGER
Jump starting a weak battery that is cracked,
frozen, has low electrolyte level, or an
open/shorted battery cell, can cause an
explosion resulting in serious personal injury.
Do not jump start a weak battery if these
conditions exist.
2. Make sure that the booster battery is a good and fully
charged lead-acid battery at 12.6 volts or greater. Use
proper sized jumper cables with short lengths to reduce
voltage drop between systems.
3. Make sure that the cables are color coded or labeled for
the correct polarity.
CAUTION
Connecting the jumper cables incorrectly
(wrong polarity) can immediately damage the
EFI system.
Be certain of battery terminal polarity and
jumper cable polarity when hooking up
batteries.
WARNING
Batteries contain acid and produce explosive
gases.
• Shield you eyes and face from the batteries
at all times.
• Do not lean over the batteries.
Note: Be sure that the vent caps are tight and level.
Place a damp cloth, if available, over any vent caps on
both batteries. Be sure that the vehicles do not touch
and that both of the electrical systems are off and at the
same rated system voltage. These instructions are for
negative ground systems only.
4. Connect the positive (+) cable to the positive (+)
terminal of the discharged battery that is wired to the
starter or solenoid as shown in
1. Positive (+) cable on
discharged battery
2. Positive (+) cable on
booster battery
3. Negative (–) cable on the
booster battery
4. Negative (–) cable on the
engine block
5. Connect the other end of the positive cable to the
positive terminal of the booster battery.
6. Connect the black negative (–) cable to the other
terminal (negative) of the booster battery.
7. Make the final connection on the engine block of
the stalled vehicle (not to the negative battery post)
away from the battery and stand back
1. Engine block
8. Start the vehicle, and remove the cables in the
reverse order of connection (the engine block (black)
connection is the first to disconnect.
