unexpected situations.
8. Always secure your work. Use clamps or a
vise to hold work when practical. It is safer
than using your hand and frees both hands
tooperate tool.
9. Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat or hearing protection must
be used for appropriate conditions.
10. Do not use on a ladder or unstable support.
Stable footing on a solid surface enables
better control of the tool in unexpected
situations.
TOOL USE AND CARE SAFETY
BE SURE to read and understand all
instructions before operating this power tool.
1. Always use clamps or other practical ways
to secure and support the work piece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead toloss of control.

a complete stop.
6. Store idle tools out of the reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
7. Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools
with sharp cutting edges are less likely to
bindand are easier to control.
8. Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tool’s
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools.

WARNING
recommendedfor this tool. Accessories that
may be suitable for one tool may become
hazardous when usedon another tool.
ELECTRICAL SAFETY
1. Avoid body contact with grounded surfaces
such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of
electric shock if your body is grounded.
2. Do not expose power tools to rain or wet
3. conditions. Water entering a power tool will
increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord
to carry the tool or pull the plug from an
outlet. Keep the cord away from heat, oil,
sharp edges, and moving parts.
5. Replace damaged cords immediately.
Damaged cords increase the risk of electric
shock.
This compressor should be used on a nominal
220V grounded circuit. Use a power cord that
is equipped with a grounding plug. Verify that
the compressor is plugged into an outlet that
has the same configuration as theplug. Do not
use an adaptor with this compressor.
EXTENSION CORDS
Keep the extensions cord clear of the working
area. Position the cord so that it will not get
caught on lumber, tools, or other
obstructions while you are working with a
power tool.
Check the extension cords before each use.
Never use the tool with a damaged cord since
touching the damaged
area could cause
electrical shock, resulting in serious injury.
NOTE
As the distance from the supply outlet
increases, you must use a heavier gauge
extension cord. Using the extension cords
with inadequately sized wire causes a
serious drop in voltage, resulting in loss of
power and possible product damage. Refer
to the table below to determine the
required minimum wire size.

Safety Valve
This valve is used to prevent the compressor from
building too much pressure. If the pressure reaches the
preset level of the motor, it will automatically pop open.
You can also pull the ring on the valve to open manually.
Air Pressure Regulator
The regulator is used to adjust the pressure inside the
line to the tool that is being used. Turn the knob
clockwise to increase the pressure and counter-
clockwise to decrease the pressure.
Tank Pressure Gauge
The gauge measures the pressure level of the air that is
stored in the tank. It cannot be adjusted by the operator
and it does not indicate the pressure inside the line.
Tool Pressure Gauge
The gauge measures the regulated outlet pressure.
Air Outlet (Universal Coupler)
The outlet is connected to the 1/4” (6.4 mm) NPT air
hose.
Tank Drain
The tank drain is used to remove moisture from the air
tank after the compressor is shut off.
Air Tank
The tank is where the compressed air is stored.
Power Cord
This compressor should be used on a nominal 220V
grounded circuit. Use a power cord that is equipped with
a grounding plug. Verify that the compressor is plugged
into an outlet that has the same configuration as the
plug. Do not use an adaptor with this compressor.
