Initial Set-Up; Step 1. Inspect & Unpack; Step 2. Assembly; Step 3. Select Suitable Location - North Star M51481A Owner's Manual

Step 1. Inspect & Unpack
Upon receipt, inspect air compressor for missing or
damaged parts. Verify that it is the compressor you
ordered.
See "Component Identification" section of this manual
for a diagram of the compressor and its components.
For missing or damaged components, please

contact NorthStar Product Support at 1-800-270-
0810.
If complete, fill out product serial number

information. See "Limited Warranty" section of
this manual.

Step 2. Assembly

1. Check that the compressor air filter is clean.
2. Check that nuts and bolts are all snug. Some
fasteners may become loose during transit.
3. If the tank drain is left open, be sure to close it
before use.
WARNING: Bursting hazard
Too much air pressure causes a hazardous risk of
bursting. Check the manufacturer's maximum pressure
rating for air tools and accessories. Regulators must
never be set to exceed the maximum pressure rating of
tank or tools.

Step 3. Select Suitable Location

WARNING: Lifting hazard
Ensure that proper lifting equipment is available to
unload and move compressor to installation site.
Location Criteria:
Where no flammable vapors, dusts, and gases

are present.
At least 15" away from walls and other objects.

Away from other heat-generating equipment.

Away from dusty/dirty conditions.

In a well illuminated area.

Positioning:
The compressor should be mounted on a dry,

firm, and level surface. It must sit level and be
stabilized since it will slide or shift during
operation if not secured.
Place the compressor as CLOSE TO THE

BATTERY as possible so the length of lead wire
required is kept to a minimum.

Initial Set-Up

Airflow:
Provide access to adequate, clean and

unobstructed airflow for cooling and air supply.
Remember the supply air is passing through the

compressor supply hoses and tools. These can
be damaged or have a shortened life if unclean
air is present or air filter is not clean and
functioning properly.
Do not allow debris to accumulate or block

airflow.
Do not operate with a tarp, blanket, or cover

surrounding the machine, which blocks air flow.
Do not place any objects against or on top of the

unit, which can also block airflow or damage unit.
Electrical:
MUST be connected to a 12V DC battery.

To prevent discharge of a vehicle battery we

recommend that you keep the vehicle running
while using the air compressor.
Wiring:
Use proper wire size (minimum 8-10 AWG) for

the positive lead wire when used for remote
installation.
Ideal operating temperatures:
40 and 100F (4 and 37C).

Operating Limitations:
15F (-9C) or above 125F (52C).

If temperatures consistently drop below 32 F (0C), you
will need to protect the safety/relief and drain valves
from freezing.
Note: Excessive moisture is likely to occur if unit is
stored in an unheated area subject to large
temperature changes. Excessive condensation on the
pump when it cools down is a sign that this may be
occurring.
WARNING: Electrical Shock Hazard
Improper electrical grounding can result in a risk of
electric shock. Electrical installation MUST be made by
a qualified electrician.
