Maintenance

2.Make sure the booster is a good and fully charged lead acid battery at 12.6 volts or greater. Use properly sized jumper cables (4 to 6 AWG) with short lengths to reduce voltage drop between systems. Make sure the cables are color coded or labeled for the correct polarity.

•Shield the eyes and face from the batteries at all times.•Do Not lean over the batteries. CAUTION

Connecting the jumper cables incorrectly (wrong polarity) can immediately damage the electrical system.

Be certain of battery terminal polarity and jumper cable polarity when hooking up batteries.

Note: The following instructions are adapted from the SAE J1494 Rev. Dec. 2001 – Battery Booster Cables – Surface Vehicle Recommended Practice (SAE – Society of Automotive Engineers).

Check Mower BladesManual background WARNING

Batteries contain acid and produce explosive gases.

Shield the eyes and face from the batteries at all times.

Do Not lean over the batteries.

Note: Be sure the vent caps are tight and level. Place a damp cloth, if available, over any vent caps on both batteries. Be sure the vehicles do not touch and that both electrical systems are off and at the same rated system voltage. These instructions are for negative ground systems only.

3.Connect the positive (+) cable to the positive (+) terminal of the discharged battery that is wired to the starter or solenoid as shown in Figure 10.

4.Connect the other end of the positive cable to the positive terminal of the booster battery.

5.Connect the black negative (–) cable to the other terminal (negative) of the booster battery.

6.MAKE THE FINAL CONNECTION ON THE ENGINE BLOCK OF THE STALLED VEHICLE (NOT TO THE NEGATIVE POST) AWAY FROM THE BATTERY. STAND BACK.

7.Start the vehicle and remove the cables in the reverse order of connection (the engine block (black) connection is the first to disconnect).
