Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.

MT1827 1/2" Heavy Duty Reversible Air Drill
THIS INSTRUCTION MANUAL CONTAINS
IMPORTANT SAFETY INFORMATION.
READ THIS INSTRUCTION MANUAL CAREFULLY
AND UNDERSTAND ALL INFORMATION
BEFORE OPERATING THIS TOOL.
• Always operate, inspect and maintain this tool in
accordance with American National Standards
Institute Safety Code of Portable Air Tools (ANSI
B186.1) and any other applicable safety codes
and regulations.
• For safety, top performance and maximum durability
of parts, operate this tool at 90 psig 6.2 bar max
air pressure with 3/8" diameter air supply hose.
• Always wear impact-resistant eye and face
protection when operating or performing
maintenance on this tool.
• Always wear hearing protection when using this
tool. High sound levels can cause permanent hearing
loss. Use hearing protection as recommended by
your employer or OSHA regulation.
• Keep the tool in efficient operating condition.
• Operators and maintenance personnel must be
physically able to handle the bulk, weight and
power of this tool.
• Air powered tools can vibrate in use. Vibration,
repetitive motions or uncomfortable positions over
extended periods of time may be harmful to your
hands and arms. Discontinue use of tool if discomfort,
tingling feeling or pain occurs. Seek medical advice
before resuming use.
• Air under pressure can cause severe injury. Never
direct air at yourself or others. Always turn off the
air supply, drain hose of air pressure and detach tool
from air supply before installing, removing or
adjusting any accessory on this tool, or before
performing any maintenance on this tool. Failure to
do so could result in injury. Whip hoses can cause
serious injury. Always check for damaged, frayed
or loose hoses and fittings, and replace immediately.
Do not use quick detach couplings at tool. See
instructions for correct set-up.
• Place the tool on the work before starting the tool.
• Slipping, tripping and/or falling while operating air
tools can be a major cause of serious injury or
death. Be aware of excess hose left on the walking
or work surface.
• Keep body working stance balanced and firm. Do
not overreach when operating the tool.
• Anticipate and be alert for sudden changes in motion
during start up and operation of any power tool.
• Do not carry tool by the hose. Protect the hose from
sharp objects and heat.
• Tool shaft may continue to rotate briefly after throttle
is released. Avoid direct contact with accessories
during and after use. Gloves will reduce the risk of
cuts or burns.
•Keep away from rotating end of tool. Do not wear
jewelry or loose clothing. Secure long hair. Scalping
can occur if hair is not kept away from tool and
accessories. Choking can occur if neckwear is not
kept away from tool and accessories.
• Drill bits can bind suddenly and cause rotation of
the work piece or tool, causing injury to arms
and/or shoulders. Enough torque is generated to
cause falls. Always use sharp bits. Use less down-
ward pressure at breakthrough.
• Do not lubricate tools with flammable or volatile
liquids such as kerosene, diesel or jet fuel.
• Do not force tool beyond its rated capacity.
• Do not remove any labels. Replace any
damaged labels.
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY
OPERATION
Locate center of new hole by using a center punch. Place drill bit
tip in punch mark. Hold drill square with work and start motor.
Apply steady, even pressure. Do not force. Too much pressure can
cause bit to break or overheat. Too little pressure will keep bit from
cutting and cause it to overheat. Reduce pressure just before bit
cuts through the work. When bit has penetrated work and is
spinning freely, take it from the work while the motor is running,
then turn off drill. If the drill jams in the work, release throttle
immediately. Disconnect the drill before removing bit and
determining cause of trouble. Do not attempt to free the bit by
starting and stopping the motor.

AIR SUPPLY
Tools of this class operate on a wide range of air pressures. It is
recommended that air pressure of these tools measures 90 PSI at
the tool while running free. Higher pressure and unclean air will
shorten the tool’s life because of faster wear and may create a
hazardous condition.
Water in the air line will cause damage to the tool. Drain the air
tank daily. Clean the air inlet filter screen on at least a weekly
schedule. The recommended hook-up procedure can be viewed
in Figure 2.
The air inlet (Figure 1), used for connecting air supply, has standard
1/4" NPT American Thread.
Line pressure should be increased to compensate for unusually
long air hoses (over 25 feet). Minimum hose diameter should be
3/8" I.D. and fittings should have the same inside dimensions.
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air line,
moisture or restrictions in air pipes or the use of hose connections
of improper size or poor conditions may reduce air supply. If
outside conditions are in order, disconnect tool from hose and take
tool to your nearest Matco authorized service center.
LUBRICATION & MAINTENANCE
Lubricate the tool daily with a good grade of air tool oil. If no
air line oiler is used, run a teaspoon of oil through the tool. The oil
can be squirted into the tool air inlet Figure 1, or into the hose at
the nearest connection to the air supply, then run the tool. A rust
inhibitive oil is acceptable for air tools.
