looks like the plug illustrated in Figure 12. Only connect the product to an outlet
having the same configuration as the plug. Do not use an adapter with this product.
In the event of an electrical short circuit, grounding reduces risk of electrical shock
by providing an escape wire for electric current. This product is equipped with a
cord having a grounding wire with an appropriate grounding plug. Plug must be
plugged into an outlet that is properly installed and grounded in accordance with
all local codes and ordinances.
Improper use of grounding plug can result in a possible risk
of electrical shock!
Do not use a grounding adapter with this product!
2. If repair or replacement of cord or plug is necessary, do not connect grounding wire
to either flat blade terminal. The wire with insulation having an external surface
that is green (with or without yellow stripes) is the grounding wire.
Never connect green (or green and yellow) wire to a live terminal.
3. Check with a qualified electrician or serviceman if grounding instructions are not
completely understood, or if in doubt as to whether product is properly grounded.
Do not modify plug provided; if it will not fit outlet, have proper outlet installed by a
qualified electrician.
WIRING
1. Local electrical wiring codes differ from area to area. Source wiring, plug and
protector must be rated for at least the amperage and voltage indicated on motor
nameplate, and meet all electrical codes for this minimum.
2. Use a slow blow fuse or a circuit breaker.
Overheating, short circuiting and fire damage will result from
inadequate wiring, etc.
NOTE: 120 volt, 15 amp units can be operated on a 120 volt circuit under the following

Operation
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.
IMPORTANT: This condensation will cause water spots
in a paint job, especially when spraying other than water
based paints. If sandblasting, it will cause the sand to cake
and clog the gun, rendering it ineffective. A filter in the air
line (MP3105), located as near to the gun as possible, will
help eliminate this moisture.
This compressor can be used for general inflation as well as
intermittent duty air tool usage. For inflation purposes, this
compressor utilizes a new technology called Rapid Inflation
Technology (RIT).
IMPORTANT: Make sure the Wheel Lock/Foot Brake is engaged
before operating the unit (See Figure 11).
LUBRICATION
This is an oilless product and DOES NOT require lubrication to
operate.
ASME SAFETY VALVE
Do not remove or attempt to adjust the safety
valve!
This valve should be checked under pressure occasionally by
pulling the ring by hand (See Figure 13). If air leaks after ring has
been released, or valve is stuck and cannot be actuated by ring, it
MUST be replaced.
CLICK-TO-SET REGULATOR KNOB
1. This knob controls air pressure to an air operated tool, or
paint spray gun.
2. Turning knob clockwise increases air pressure at outlet.
3. Turning counterclockwise will lower air pressure at outlet.
4. Fully counterclockwise will shut off flow of air completely.

2. Be sure this gauge reads ZERO before changing air tools or disconnecting hose from
outlet.
TANK PRESSURE GAUGE
Gauge shows pressure in tank indicating compressor is building pressure properly.
STORAGE TOP
The storage tray compartments, located on the top of the compressor, are designed for
easy tool storage. Unique tool kits, available at your local retailer or on www.chpower.
com, store easily on top of the unit.
RAPID INFLATION TECHNOLOGY
When the compressor is used in this mode, the air being produced from the
compressor pump will go directly to the recoil hose which will attach to the bottom of
the compressor. This will eliminate waiting for the compressor tank to fill up which will
allow for significantly faster inflation.
Instant air hose will get hot while the compressor is
on and during the inflation process.
Drain water from tank prior to inflation.
TO USE COMPRESSOR FOR INFLATION:
1. Connect recoil hose to open port located on the bottom of compressor (See Figures
10 and 14). The coil hose and blow gun must remain attached so that the unit
operates properly.
2. Attach blow gun to the other end of the recoil hose. The blow gun should ALWAYS
be connected to the recoil hose.
3. To inflate balls, rafts, etc. attach inflation needle or nozzle to the end of blow gun.
4. To inflate tires, attach tire inflation valve to the end of blow gun.
5. Attach the blow gun with appropriate inflation device to object needing inflation.
6. Turn on compressor and inflate by squeezing the trigger.
Use caution to avoid over inflation.
7. When inflation is complete, blow gun can be attached to the clip that is molded on
the side of the top shroud for convenient storage.
TO USE COMPRESSOR FOR AIR TOOL USAGE:
1. Connect separate hose (not included) to the coupler located below pressure
regulator by pulling the sleeve on coupler all of the way back, then push hose into
coupler and release sleeve (See Figure 16).
2. Close regulator (turn knob fully counterclockwise to the left).
3. Turn compressor on and allow it to fill tank until it reaches automatic shut off
pressure.
4. Attach air tool, paint gun, nailer, etc. to end of air hose.
5. Adjust regulator for desired application. Regulator has preset “click-to-set” feature
which should closely match application pictures on outlet pressure gauge.
6. Use compressor for desired application.

1. Plug the compressor in and run until shut off pressure is reached (see Operating
Procedure).
2. Wearing safety glasses, pull the ring on the safety valve to release pressure from
compressor tank. Use your other hand to deflect fast-moving air from being
directed toward your face.
3. The safety valve should automatically close at approximately 40-50 psi. If the safety
valve does not allow air to be released when you pull on the ring, or if it does not
close automatically, it MUST be replaced.
DRAIN TANK
1. Turn compressor off at foot pedal switch.
2. Check air pressure in tank. To properly drain tank of condensation, tank pressure
should be between 20-60 psi. Drain system will not work if there is no pressure
in the tank. If tank pressure is above 60 psi, drain tank by pulling the ring on the
safety valve. The safety valve should release air and then automatically close at
approximately 40-50 psi.
3. Slowly turn easy drain knob, located below the tank gauge, to the left
(counterclockwise) until fluid begins to fill drain cup. Watch draining to make sure
drain cup does not overflow. If there is a lot of fluid in the tank, you may need to
close drain knob by turning fully to the right (clockwise) then remove the drain cup
to dispose of fluid.
4. When fluid stops draining, close drain knob by turning all the way to the right
(clockwise).
5. Lift cup up and pull out to dispose of drained fluid. Reinsert cup, making sure to
secure in place.

CLEANING
Turn power OFF and clean dust and dirt from motor, tank, and
air lines.
IMPORTANT: Unit should be located as far from spraying area
as hose will allow to prevent over-spray from entering the pump.
AIR FILTER
Check air filter to be sure it is clean. To service the air filter, tip
the unit back, resting the wheels and handle on the floor (See
Figure 19). Remove the filter housing cover. Remove filter and
blow off dirt. Replace air filter if it can not be cleaned. Place filter
back in the housing base. Replace cover.
LUBRICATION
This is an oilless type compressor requiring no lubrication.
THERMAL OVERLOAD PROTECTOR
This compressor is equipped with an automatic
reset thermal overload protector which will shut
off motor if it becomes overheated.
If thermal overload protector shuts motor OFF frequently look
for the following causes:
1. Low voltage
2. Lack of proper ventilation
If the thermal overload protector is actuated,
the motor must be allowed to cool down before
startup is possible. The motor will automatically restart without
warning if left plugged into electrical outlet and unit is turned on.
