transversely or longitudinally more than 10˚.
1. Place air compressor at least 30 cm away from obstacles that may prevent proper ventilation.
Do not place air compressor in an area:
-where there is evidence of oil or gas leaks.
-where flammable gas vapors or materials may be present.

ELECTRICAL:
DANGER
Improper connection of the equipment-grounding conductor can result in a risk
of shockor electrocution.Check withaqualified electrician or service personnel
if you are in doubt as to whether the outlet is properly grounded. Do not use any type of
adapter with this product. If repair or replacement of the cord or plug is necessary, do not
connect the grounding wire to either flat blade terminal.The wire with insulation having
an outer surface that is green with or without yellow stripes is the grounding wire.
WARNING
This product must be grounded. If there should be a malfunction or breakdown,
grounding provides a path of least resistance for electric current to reduce the
risk of electric shock. This product is equipped with a cord having an equipment-
grounding conductor and agrounding type plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance with all local
codes and ordinances.
1. SENCO® DOES NOT RECOMMEND THE USE OF EXTENSION CORDS as this can create power loss and
overheating of the motor.Useofanadditional air hose is recommended rather than an extension cord. If use ofan
extension cord is unavoidable, it should be plugged into a GFCI found in circuit boxes or protected receptacles.
When using an extension cord, observe the following:
Cable Length Wire Gauge
Up to 8 meters 12AWG
Up to 30 meters 10AWG
Up to 50 meters 8AWG
Up to 75 meters 6AWG
Use only 3-blade extension cords that have 3-blade grounding-type plugs and 3-slot cord connectors that will
accept the plug from the product. Use only extension cords having an electrical rating not less than the rating of
the product. Do notuse damaged extension cords.Examine extension cord before usingand replaceif damaged.
Do not abuse extension cord and do not yank on any cord to disconnect. Keep cord away from heat and sharp
edges.Always shut off the air compressor switch before removing the plug from the receptacle.
Ensure the oil levelis above the minimum notch and belowthe maximum notch on the dipstick. If low, add
compressor pump oil.
