for specific installation instructions.

welder. This will require a 1/2" combination wrench. These Big Blues also contain a battery disconnect switch which is
accessed from the side panel of the machine. This switch must be turned to the ON position prior to operation. See the owner's
manual for more information.
6. Oil – Check the oil level. The unit is shipped with oil so the addition of oil is not necessary on new welders/generators.

8. Coolant (Big Blue's Only) – Check the coolant level on overflow/recovery tank from the access panel on top of the welder. The unit
is shipped with coolant so the addition of coolant is not necessary on new welders.
9. Air Compressor Oil (Air Pak models only) – Check the air compressor oil gauge as described in the owner's manual. This unit is
shipped with air compressor oil so the addition of oil is not necessary on new welders. See owner's manual for more details on
the air compressor system.
10. Installation Location – Verify 18" of clearance on each side and the top of the unit to ensure proper airflow for cooling.

instruction available in the owner's manual.
