Instructions for Installation/Set-up, Operation, Maintenance, & Storage
This NorthStar® belt-driven compressor pump has either a single stage 2-cylinder pump (Model 4592900),
2-stage 3-cylinder pump (Model 4593000) or a 2-stage 2-cylinder pump (Model 4593100), made with heavy-duty cast
iron cylinders for long life, and a compact design rated for 130 maximum PSI (4592900) or 175 maximum PSI
(4593000 and 4593100). Its continuous-duty rating ensures long-lasting performance, and its cast iron pump head
ensures superior heat dissipation.
Read and understand this Owner's Manual completely before using. Keep this manual for future review. Failure to
properly set up, operate and maintain the compressor pump in accordance with this manual could result in serious
injury or death to operator or bystanders.
WARNING: SPECIAL HAZARDS
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.
Not For Breathing Air: NorthStar compressor pumps 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, motor and discharge tubing are hot surfaces that can cause burn injuries.
Detailed safety information about these hazards appears throughout this manual.
Inspect Upon Delivery: FIRST! Inspect for missing or damaged components. See "Initial Set-Up" section for where
to report missing or damaged parts.
Check Pump Oil: Pump is NOT shipped with oil. Check the pump oil level before starting. See "Preparing for
Operation" section of this Owner's Manual for capacity and viscosity.
Install a Regulator: We recommend installing a regulator on the compressor at each distribution point to maintain
constant pressure in the outlet hose line and provide reduced pressure appropriate for air tool being used.
Run Pump Unloaded for Break-in Period: Before initial use, open drain valves and run compressor pump for 30
minutes to break in pump parts.
Follow Maintenance Schedule: Pump, air filter, and tank require periodic inspection and servicing to provide
efficient function and long life. See "Maintenance Schedule" for frequency of servicing.
