Safety
DEFINITIONS
DANGER!
WILL cause DEATH, SEVERE INJURY or substantial
property damage.
WARNING!
CAN cause DEATH, SEVERE INJURY or substantial
property damage.
CAUTION!
WILL or CAN cause MINOR INJURY or property
damage.
GENERAL SAFETY PRECAUTIONS
ALWAYS wear eye protection when operating or
servicing compressor.
NEVER operate where flammable or explosive liquids or
vapors such as gasoline, natural gas and solvents are
present.
NEVER remove, paint over, or deface decals. Replace
any missing decals.
NEVER operate with guards or shields removed,
damaged or broken.
NEVER operate indoors. This compressor is intended for
outdoor use only. Avoid inhaling exhaust fumes, risk of
asphyxiation. Exhaust fumes are deadly.
NEVER add fuel when the product is operating or hot.
NEVER directly inhale compressed air.
NEVER over-pressurize the receiver tank or similar
vessels beyond design limits.
NEVER use a receiver tank or similar vessels that fail to
meet the design requirements of the compressor.
NEVER drill into, weld or otherwise alter the receiver
tank or similar vessels.
NEVER remove, adjust, bypass, change, modify or make
substitutions for safety/relief valves, unloader valve or
other pressure control related devices.
NEVER use air tools or attachments without first
determining the maximum pressure recommended for
that equipment.
NEVER point air nozzles or sprayers toward people or
animals.
NEVER touch the compressor pump, engine or
discharge tubing during or shortly after operation. These
parts become hot.
BREATHING AIR PRECAUTION
NorthStar air compressors are not designed, intended
or approved for breathing air. Compressed air should not
be used for breathing air applications unless treated in
accordance with all applicable codes and regulations.
Receipt and Inspection
Before signing the delivery receipt, inspect for damage
and missing parts. If damage or missing parts are
apparent, make the appropriate notation on the delivery
receipt, then sign the receipt. Immediately contact the
carrier for an inspection. All material must be held in the
receiving location for the carrier’s inspection. Delivery
receipts that have been signed without a notation of
damage or missing parts are considered to be delivered
“clear.” Subsequent claims are then considered to be
concealed damage claims. Settle damage claims directly
with the transportation company.
If you discover damage after receiving the air
compressor (concealed damage), the carrier must be
notified within 15 days of receipt and an inspection must
be requested by telephone with confirmation in writing.
On concealed damage claims, the burden of establishing
that the compressor was damaged in transit reverts back
to the claimant.
Read the compressor nameplate to verify it is the model
ordered, and read the motor nameplate to verify it is
compatible with your electrical conditions. Make sure
electrical enclosures and components are appropriate.
