Air Supply; Lubrication And Maintenance - Matco Tools MT1910 Instructions De Fonctionnement

OPERATION
Always turn off the air supply, drain hose of air pressure and detach
tool from air supply before installing, removing or adjusting any part or
accessory on this tool, or before performing any maintenance on this
tool.
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 pres sure . Do not force . Too much pressure can cause bit to break
or over heat . Too little pressure will keep bit from cutting and cause it to
FEATURES
• Precise control. Tip valve provides true variable speed performance.
• Easy operation. Reversing collar allows user to quickly switch from forward to reverse.
• Easy confined drilling. Industrial grade Jacobs
• Quiet power. Only 83 dBA making it one of the quietest tools in its class.

AIR SUPPLY

Tools operate on a wide range of air pressures . It is recommended
that air pressure measures 90 psig at the tool with the trigger fully
depressed and no load applied to the tool . Higher pressure (over
90 psig; 6 .2 bar) raises performance beyond the rated capacity of
the tool, which will shorten tool life and could cause injury.
Always use clean, dry air . Dust, corrosive fumes and/or water in
the air line will cause damage to the tool . Drain the water from
air lines and compressor prior to running tool . Clean the air inlet
filter screen weekly . The recommended hookup procedure can
be viewed in FIG . 1 .
The air inlet used for connecting air supply has standard 1/4" NPT .
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 and
be tightly secured .
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location .

overheat. Reduce pres s ure just before bit cuts through the work. When
bit has pen e trat ed work and is spin ning freely, take it from the work
while the motor is run n ing, then turn off drill. If the drill jams in the work,
release throttle immediately . Dis con nect the drill before re mov ing bit and
de ter min ing cause of trou ble . Do not attempt to free the bit by starting
and stopping the motor .
NOTE: During operation, safety goggles should always be worn to guard
against flying rust and chips (users and bystanders).
® Chuck allows for drilling in confined areas that require 3-1/2" clearance.
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 . Grit or
gum deposits in the tool may cut power and may be corrected
by cleaning the air strainer and flushing out the tool with gum
solvent oil or an equal mixture of SAE #10 and kerosene . If outside
conditions are in order, disconnect tool from hose and take tool to
your nearest authorized service center .

LUBRICATION AND MAINTENANCE

Lubricate the air motor daily with high quality air tool oil . If no air
line oiler is used, run 1/2 oz . of oil through the tool . The oil can
be squirted into the tool air inlet 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 .
WARNING: After an air tool has been lubricated, oil will discharge
through the exhaust port during the first few seconds of operation .
The exhaust port must be covered with a towel before applying
air pressure to prevent serious injury.
