threads at the end of the fitting.

CAUTION:
• Improper jump starting procedures can cause an explosion resulting in
personal injury.
• Sparks near batteries can cause explosions.
• Do not allow jump cable ends to touch each other or the machine.
• Battery acid can cause personal injury if it contacts skin or eyes.
Always wear eye protection when jump starting a machine.
• Always connect battery positive (+) to battery positive (+) and battery
negative (-) to ground on the machine. Make the final ground connec-
tion away from the battery.
• Allowing the two machines to touch during jump starting can cause
damage to bearings and electrical circuits.
• This machine has a 12 volt starting system. Use the same voltage (12
volts) for jump starting. Use of higher voltage can damage the electri-
cal system.
• Never charge a frozen battery.
