12 Volt Electric Start Petrol and Diesel Air Compressors
Electric start petrol and diesel air compressors must be connected to a 12 Volt battery in
order to utilize this feature.
Use a 12 Volt battery of sufficient amp-hour and cold cranking amp capacity in
accordance with the engine manufacturer’s instructions.
Connect the battery positive (+) cable to the starter solenoid terminal.
Connect the battery negative (−) cable to an engine mounting bolt, frame bolt, or other
good engine ground connection.
Connect the battery positive (+) cable to the battery positive (+) terminal.
Connect the battery negative (−) cable to the battery negative (−) terminal.
Take care not to connect the battery in reverse polarity as this may damage the battery
charging system.
Check the battery cable connections to be sure the cables are tight and free of
corrosion. Remove any corrosion, and coat the terminals and cable ends with
corrosion-preventing grease.
Remove the cable from the battery negative (−) terminal before carrying out any
maintenance or repairs.
