Recommended Jump

Starting Procedure

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.

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).

WARNING

Batteries contain acid and produce explosive gases.

Service Interval: As required		• Shield the eyes and face from the batteries

	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 the booster is a good and fully charged lead acid battery at 12.6 volts or greater. Use
