Operation
INITIAL START-UP
1. Pump is shipped with oil. Remove the oil cap and
check pump oil level. Add SAE 30 Non-detergent
pump oil (NorthStar part #35605), if necessary. Hand
tighten breather cap.
2. Turn outlet valve to open airflow.
3. Move pressure switch lever to the OFF position
and plug in power cord (if applicable). Move
pressure switch to the AUTO position to run the unit.
CAUTION!
Unusual noise or vibration indicates a
problem. Do not continue to operate until you identify
and correct the source of the problem.
NOTE:
Electric models are equipped with a
pressure switch that automatically turns the motor
OFF when the tank pressure reaches a preset level.
After air is used from the tank and drops to a preset
low level, the pressure switch automatically turns the
motor back on.
CAUTION!
Do not attach air tools to open end of
the hose until start-up is completed and the unit
checks out OK.
4. Run the unit for 30 minutes, with ball valve open,
to break in pump parts.
5. Move the pressure switch lever to OFF and turn
the outlet valve to shut off air flow. The compressor
is now ready for use.
6. After 50 hours of operation change the
compressor oil.
WARNING!
Never disconnect threaded joints with pressure in
the tank.
NOTE:
Reduce tank pressure below 10 psi, then
drain moisture from tank daily to avoid tank
corrosion. Drain moisture from tank(s) by opening
the drain petcock located on the foot ring.
COMPRESSOR LUBRICATION
CAUTION!
Do not operate without lubricant or with
inadequate lubricant. Use of compressor without
lubricant or inadequate lubricant voids all warranties.
Synthetic Lubricants
Synthetic lubricants are recommended after 50 hour
break-in. Compressor life is greatly increased with
the use of synthetic lubricants.
CAUTION!
If you will
be using synthetic lubricant, all downstream piping
material and system components must be
compatible.

Alternate Lubricants.
You may use petroleum-based lubricant
that is premium quality, does not contain detergents, contains
only anti-rust, anti-oxidation, and anti-foam agents as additives,
has a flashpoint of 440
F (227
C) or higher, and has a auto-
ignition point of 650
F (343
C) or higher.
See the petroleum lubricant viscosity table below. The table is
intended as a general guide only. Heavy duty operating
conditions require heavier viscosities.

MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets
as it comes from an air compressor pump. When
humidity is high or when a compressor is in
continuous use for an extended period of time, this
moisture will collect in the tank. When using a paint
spray or sandblast gun, this water will be carried
from the tank through the hose, and out of the gun
as droplets mixed with the spray material. If this is
not acceptable for your application, an external air
dryer must be added to the system.
