Owner’s Manual 

Gasoline Portable Air Compressor  

 

(For Outdoor Use only)

 

Instructions for Installation/Set-up, Operation, Maintenance, & Storage 

 

This NorthStar® belt-driven compressor has a single stage 2-cylinder pump, an engine with cast iron cylinders for 
long life, and a compact design rated for 130 maximum PSI. Its continuous-duty rating ensures long-lasting 
performance, and its cast iron pump head ensures superior heat dissipation. Lift eyes are provided for lifting or tying 

down.  

 

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. ONLY run air compressor OUTDOORS and at least 20 feet from the home, away 
from windows, vents and air intakes, to allow proper ventilation. If you start to feel sick, dizzy, or weak while using the air 

compressor, shut off the engine and get to fresh air RIGHT AWAY. 

 

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, drain plug 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.
