Read and understand this Owner’s Manual completely before using and keep this manual for review. Failure to
properly set up, operate, and maintain this compressor in accordance to this manual could result in injury or death to
operator or bystanders.
WARNING: SPECIAL HAZARDS
CO Poisoning: Exhaust from engine contains carbon monoxide, a poisonous gas that can cause carbon monoxide
poisoning and possible death if inhaled.
Injection Injury: High-pressure air stream can pierce skin and underlying tissues, leading to serious injury and possible
amputation. Such an injection injury can result in blood poisoning and/or severe tissue damage.
Flying Debris: High-pressure air stream can cause flying debris and possible surface damage.
Electric shock: Operating equipment in wet conditions or near water can cause electric shock.
Not For Breathing Air: NorthStar compressors are NOT designed, intended, or approved for supplying breathing air. No
compressed air should be used for breathing unless air is treated in accordance with applicable standards.
Fire/Explosion: Sparks from air powered tool heads or attachments can ignite fuel or other flammable liquids or vapors in
the vicinity. Exceeding the maximum pressure for air tools or attachments could cause them to explode.
Burns: Compressor pump, engine and discharge tubing are hot surfaces that can cause burn injuries.
Detailed safety information about these hazards appears throughout this manual.
Equipment Protection Quick Facts
Inspect Upon Delivery: FIRST! Inspect for missing or damaged components. See “Initial Set-Up” section for where
to report missing or damaged parts.
Add Engine Oil: Engine is shipped without oil. See engine manual for instructions on capacity and viscosity
recommendations.
Check Pump Oil: Pump is shipped with oil. Check the pump oil level before starting. See “Preparing for Operation”
section of this Owner’s Manual for capacity and viscosity.
Use Mechanical Lifting Equipment: Compressor is shipped on a pallet and is too heavy to handle manually. Use
proper lifting equipment for unloading and moving to installation site. Lifting eyes are provided.
Run Pump Unloaded for Break-in Period: Before initial use, open ball valve and run compressor for 20 minutes to
break in pump parts.
Follow Maintenance Schedule: Engine, pump, air filter, and tank require periodic inspection and servicing to keep
compressor functioning efficiently. See “Maintenance Schedule Summary”for frequency of servicing.
