: To install dead handle
(Figure 1), rotate handle counterclockwise to
loosen retainer; then slide retainer over chuck and
onto drill body, and rotate to a convenient angle.
Retighten handle to secure.
Note: Chuck must remain clear of retainer.
Operation
The pneumatic drill must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1.
Remove protective cap from air inlet (Figure
1). If an in-line oiler is not being used, add 4
or 5 drops of air tool oil (not included) into the
air inlet.
2.
Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90 psi.
IMPORTANT:
Connecting a quick-change
coupling directly to the tool is not
recommended, as vibration may cause the
connection to fail. Instead, add a leader hose
and install any quick-change couplings
farther down the line.
3.
Insert chuck key into one of the holes on the
chuck, so it meshes with teeth on drill chuck.
Rotate counterclockwise to open chuck jaws.
4.
Insert bit (not provided) into chuck, and
center it between the jaws. Tighten chuck by
hand while aligning bit.
Note: Insert only the shank of a twist drill bit;
its flutes should remain free of the chuck
jaws.
5.
Insert chuck key and rotate clockwise to fully
tighten chuck.
6.
Select rotation direction (F/R).
7.
Place bit against work item and gently press
trigger. Speed is variable, determined by
pressure against trigger. Begin at slow
speed and gradually increase as you drill.
8.
Release trigger to stop drill.
Maintenance
Lubrication
The drill should be lubricated
daily
(or before
each use) with air tool oil through the air inlet.
During continual operation, it should be re-oiled
every 1 to 2 hours. This can be done with an in-
line oiler, or manually. If done manually, proceed
as follows:
1.
Disconnect air hose from tool.
2.
Place 4 or 5 drops of air tool oil into air inlet.
NOTE: Air tool oil not provided; it is available
at most major hardware and tool stores. SAE
#10 oil or sewing machine oil may be used
as a substitute. Do not use detergent oil.
