GENERAL SAFETY RULES
Do not operate power tools in an explosive atmosphere, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or
fumes.
Grounded tools must be plugged into a properly installed and grounded outlet in
accordance with all applicable codes and ordinances. Never remove the ground-
ing prong or modify the plug in any way. Do not use adaptor plugs. Check with a
qualified electrician if you are in doubt as to whether the outlet is properly
grounded. If the tool should electrically malfunction or break down, grounding provides
a low-resistance path to carry electricity away from the user.
Double insulated tools are equipped with a polarized plug (one blade is wider than
the other). This plug will only fit into a polarized outlet one way. If the plug does
not fit fully into the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet. Do not change the plug in any
way. Double insulation eliminates the need for the three-wire grounded power cord
and grounded power supply system.
Do not abuse the power cord. Never use the power cord to carry the tool or pull
the plug from an outlet. Keep the power cord away from heat, oil, sharp edges, or
moving parts. Replace damaged power cords immediately. Damaged power cords
increase the risk of electric shock.
Stay alert. Watch what you are doing, and use common sense when operating a
power tool. Do not use a power tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating a power tool may
result in serious personal injury.
Dress properly. Do not wear loose clothing or jewellery. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewellery, or long hair can get caught in moving parts.

do the job better and safer at the rate for which it is designed. Do not force the tool, and
do not use the tool for a purpose for which it is not intended.
Do not use the power tool if the power switch does not turn it on or off. Any tool that
cannot be controlled with the power switch is dangerous, and must be replaced.
Disconnect the power cord plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
Maintain tools with care. Properly maintained tools are less likely to bind, and are easier
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.
Check for misalignment or binding of moving parts, broken 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.
Use only accessories that are recommended for your model by the manufacturer.
Accessories that may be suitable for one tool may become hazardous when used on
another tool.
Tool servicing must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users. Keep children away from power tools.
CAUTION Risk of Bursting – Tilt tank to drain.

Avoid unintentional starting. Make sure you are prepared to begin work before turning
on the Air Compressor.

GLOSSARY OF TERMS
Become familiar with these terms before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air delivery.
PSI: Pounds per square inch ; a unit of measure of pressure.
Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to use
your accessory. When the tank pressure drops to a certain level, the motor will restart
automatically. The pressure at which the motor automatically restarts is called "cut-in"
pressure.
Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in
the air tank begins to build. It builds to a certain pressure before the motor automatically
shuts off - protecting your air tank from pressure higher than its capacity. The pressure at
which the motor shuts off is called "cut-out" pressure.
Branch Circuit: Circuit carrying electricity from the electrical panel to the outlet.
Air compressors should be operated on not more than a 50% duty cycle. This means that
forcing an air compressor to pump air more than 50% of one hour is considered misuse,
because the air compressor is undersized for the required air demand. Maximum compressor
pumping time is 30 minutes per hour.

Precautions
Drain the moisture from the tank daily to help prevent corrosion.
Pull the pressure relief valve ring daily to ensure proper function and clear possible obstructions.
To provide proper ventilation for cooling, the compressor must be kept at least 12” (31 cm) from
the nearest wall, in a well-ventilated area.
Fasten the compressor securely and release tank pressure before transporting.
Protect the air hose and electric cord from damage and puncture. Inspect them weekly for weak or
worn spots, and replace if necessary.
To reduce the risk of electric shock, do not expose to rain. Store indoors.
Never operate the compressor if the power cord or plug is damaged. Take the
equipment to the nearest Authorized Service Center, to have it replaced.
Basic Air Compressor Components
17
Oil-less air compressors are factory lubricated for life and do not
require any further lubricated.
The basic components of the air compressor are the electric motor,
pump, pressure switch, and tank. The electric motor (A) powers the
pump. The electric motor is equipped with an overload protector and
an automatic reset. If the motor becomes overheated, the overload
protector will shut it down to prevent damage to the motor. When the
motor cools sufficiently, it will automatically restart.
The pump (B) compresses the air and discharges it into the tank.
The tank (C) stores the compressed air.
The pressure switch (D) shuts down the motor and relieves air
pressure in the pump and transfer tub when the air pressure in the tank
reaches the kick-out pressure. As compressed air is used and the
pressure level in the tank drops to the kick-in pressure, the pressure switch restarts the motor
automatically, without warning, and the pump resumes compressing air.
Fig. E
Assembling the Compressor
1.Unpack the air compressor. Inspect the unit for damage. If the unit has been
damaged in transit, contact the carrier and complete a damage claim. Do this
immediately as there is a time limit to damage claims.
2 . Tighten the handle into its position with the screws included.
3 . Check the compressor’s specifications label to ensure that you have received the model ordered,
and that it has the required pressure rating for its intended use.
4 . Locate the compressor according to the following guidelines:
a . Position the compressor near a grounded electrical outlet (see GROUNDING INSTRUCTIONS,
above).
b . The compressor must be at least 12”(31 cm) from any wall or obstruction, in a clean,
well-ventilated area, to ensure sufficient air flow and cooling.

Important Information
Compatible Compressors: Guidelines for Proper Use and Operation
Be sure to use the proper air compressor with Mastercraft® air-powered tools. The compressor that
is being used must be able to supply the proper amount of pressure (PSI) to the tool. Verify that the
tool does not require more SCFM (Standard Cubic Feet per Minute) than the compressor can
deliver without running continuously.
General Use
This Mastercraft® Air-powered Ratchet features a light aluminium body and a steel angle head.
Exhaust is discharged to the front, and grips are ergonomically designed. This ratchet is designed
for automotive applications such as removing or replacing radiators and spark plugs, air condition-
ing system repairs, and water pump repairs. It is compact, and powerful enough to turn bolts in
confined spaces.
Air System
1.Always use clean, dry, regulated compressed air at 90 PSI.
2.Do not exceed the maximum and minimum pressures. Operating the tool at the wrong pressure
(too low or too high) will cause excessive noise or rapid wear.
3.Keep hands and other parts of the body away from the tool's discharge and working areas when
connecting the air supply.
4.It is recommended that a filter-regulator-lubricator be used, and that it be located as close to the
tool as possible (see Fig. I).
5.If a filter-regulator-lubricator is not installed, place up to 6 drops of air tool oil into the NPT
inlet plug before each use.
6.If a filter-regulator-lubricator is installed, keep the air filter clean. A dirty filter will reduce the air
pressure to the tool, which will cause a reduction in power, efficiency, and general performance.
7.For optimal performance, install a quick connector to the tool and a quick coupler on the hose, if
applicable.
8. Verify that all of the connections in the air supply system are sealed in order to prevent air from
leaking.
