!WARNING
Read this manual thoroughly and become completely familiar
with the air drill before using it. We don’t take responsibility
for an accident or malfunction caused by misuse or improper
operation.
Keep this manual as a ready reference for anyone who may use
the air drill.
If this instructions manual is missing or any warning missing or
defaced (damaged or illegible), replace with a new one. The
instructions manual and label are available through your local
C.S UNITEC dealer.
If the air drill is to be leased, loaned, or sold to anyone, this
manual must be with the air drill.
The air drill is an air tool designed for drilling holes with a
drill. Do not use the air drill for purposes other than specied;
otherwise an accident may result.
It is recommended to install a lter, a pressure reducing valve
and an oiler at the air inlet port.
Do not use an air pressure of higher than 0.6 MPa. Otherwise,
the internal parts or chuck may be damaged, causing an
accident.
Use accessories in a proper manner. If you have any question
about how to use them, contact their respective manufacturers
or dealers. Misuse of accessories can cause an accident.
Before starting operation, remove all tools used for installation
of a tool from the air drill. Tools may y off and cause injury.
If you have any question about the products or the description
in this manual, contact us or your local C.S UNITEC dealer.
WARNING
Safety precautions to be taken when
using air drills - BEFORE USE
Lock the work securely. Otherwise, the work might y,
causing a serious accident.
Hold the air drill rmly and prepare for reaction force. Reaction
force changes abruptly when the drill penetrates through the
work. Avoid operating a large air tool alone; otherwise, its
reaction torque may whack you.
Do not make jerky starts of the air drill. There is danger of
causing an accident or malfunction of the machine. Operate the
starting switch slowly.
WARNING
Safety precautions to be taken when
using air drills - DURING USE
!
!
!WARNING
Wear protective glasses. Use any other appropriate protective
gear such as ear plugs and protective shoes.
Check the rotating direction of the direction lever before starting
the air drill. If the air drill rotates in the direction you don’t expect,
you might get injured. Make sure to stop the air drill before
switching over the rotating directions.
Use caution not to get burned. The head tool such as a drill is
very hot immediately after use. Do not touch it inadvertently.
Securely tighten the air hose connection if any looseness is found
during operation. If the air hose comes off during operation, it
will jump, and may cause an accident.
!CAUTION
When the air drill is not provided with an oiler, add approximately
0.5 ml of turbine oil (ISO VG32 or equivalent) through the air
supply port, before and after operation. Then allow the air drill to
run without load for 2 to 3 seconds, with care not to allow dirt or
dust into the system. Unlubricated operation may cause the air
drill to fail to operate normally, thus resulting in an accident.
When the air drill is provided with an oiler, add turbine oil (ISO
VG32 or equivalent) and adjust the drip rate of oil to a few drips
per minute. Unlubricated operation may cause the air drill to fail
to operate normally,l thus resulting in an accident.
Before starting each shift, drain the tank or air lter. Air
containing a lot of water will cause the malfunction of the air drill
or result in an accident.
Use caution not to allow the entrance of dirt into the unit when
connecting the air hose. Failure to protect the unit against the
entrance of foreign matter may cause the malfunction of the air
drill or an accident. Before connecting the air hose to the air drill,
idle the machine until no dirt or water comes out of it, and wipe
away any dirt or dust from the air hose connection area.
Safety precautions to be taken when
using air drills - WHEN INSTALLING
OR CHANGING DRILLS
Remove the air hose before removal and installation of a tool
such as a drill.
If the air drill starts rotating unintentionally, it may cause an
accident. When any protective device (such as coupler) is not
equipped which automatically shuts off the air, close the main
cock, operate the machine once to discharge the air remaining
inside the air hose before removing it. Otherwise, the air
hose can jump about due to the remaining air pressure when
disconnected.

Pictorial Nomenclature
!WARNING
Use the proper head tool (drill chuck, drill socket, or drill) that meets the requirements
(dimensions) of your air tool.
Use of any improperly sized head tool may result in an accident.
Install the head tool such as a drill securely.
Poor installation of the head tool such as a drill may cause an accident, malfunction of the air
drill or premature service life of the socket.
When installing the drill to a large air tool (see the gure below), loosen the feed handle by
turning counterclockwise approximately 10mm from its fully clockwise (tightened) position.
A drill comes off when the feed handle is turned (tightened) fully clockwise.
Please make sure to remove oil or dust on taper part both of unit and drill chuck when you
install drill chuck (or drill) into the body.
If not, it will be at risk of coming off.

Instructions For Use
FOR SMALL AIR TOOLS :
1.) Hold the tool with both hands.
2.) Press the tip of the drill vertically against the place where a
hole is to be drilled.
3.) Push the lever slowly to rotate the drill. When the lever is
released, the drill will stop
FOR LARGE AIR TOOLS:
1.) Normally hold the air tool by two persons - one holding the
holder; the other the grip. Reaction torque may whack you
if the air tool is held by yourself. Use of an auxiliary tool as
shown on the next page allows for safer and easier operation.
2.) Press the tip of the drill vertically against the place where a
hole is to be drilled.
3.) Grip Type - Turn the grip slowly counterclockwise (R
position) to rotate the drill clockwise. The the grip is returned
to the neutral position (zero position), the drill will stop rotating.
When the grip is turned clockwise (L position), the drill will
rotate counterclockwise.

Maintenance and Inspection
Make sure to perform maintenance and inspection at regular
intervals. It is recommended to perform maintenance and
inspection at intervals of either a total number of tightening of
100,000 operations or one year, whichever comes rst.
It is advisable to disassemble and adjust the air drill at regular
intervals. To keep the performance and avoid an unexpected
accident, it is advisable to ask a specialist to disassemble and
adjust the air drill at regular intervals. Record and store the
results of measurements taken with a C.S UNITEC torque meter
as well as torque data after bolt tightening.
WARNING
!
Unauthorized modication or repair can cause an accident.
We don’t take any responsibility for an accident or malfunction
if the air drill is modied or repaired by the user himself. The
repair, disassembly, and adjustment must be left to your local
C.S UNITEC dealer.
