• Use only approved inserting tools.
• Prior to operating tool, make sure that collet/drill chuck and drill bit is securely installed.
• Prior to operating tool, remove key from chuck (if applicable).
• If the machine locks-up, an increased reaction torque occurs. Reason for lock-up: Tool
operates over capacity; jamming of the drill bit in material or when drill bit breaks
through the material.
• Do not allow the drill bit to rattle on the work-piece as this is likely to cause a substan-
tial increase in vibration.
• Reduce down pressure, shortly before bit breaks through the material to be drilled (on
thin work-pieces there is a danger that the drill may catch and pull the work-piece up-
wards).
• After turning-off the machine, the tool will continue to rotate (inertia). Lay aside
handheld machines in a safe way and position and wait for standstill. Do not apply

5.4 Usage in an Ex- area
Always follow the safety instructions while usage the air-drill in an EX-area!
Grounding The air drill must be grounded, for example by using
•an air-supply line made of metal or
•an electrically conductive hose.
The resistance between drill and ground has to be measured
(requirement: < 10
6
Ω).
Only use drive attachments that correspond to guideline ATEX
2014/34/EU, ISO 8000-36 and ISO 8000-37.
The explosion-proof air drills correspond to the design requirements of
the design group I M2 and II category 2 G, or IIB Gb. Those drills are
suited for the installation into Zone 1 and Zone 2.
Temperature
Class
You can find the temperature class that is permitted for the air motor on
the model tag (Ex-Protection-Marking).
Protection Class All air drills must correspond – for a minimum – with the standard
EN 60529 of the protection class IP 54. They are designed for the used
in dusty or damp environments.
Ambient
Conditions
Make sure that the drill is sufficiently ventilated and that there is no
additional warming source (i.e. such as a clutch, inserted tools).
Connection Open inlet- and exhaust ports are not permissible. Those type of ports
have to be closed, using either a fireproof filter or hosing. If only hosing
is connected to any of the open ports (without the use of a fireproof
filter), then that hosing has to be piped out of the explosive area.
Only used hoses or piping suitable for explosion-hazardous areas for
connecting the drill.
The possible entry of any solid particles into the compressed air inlet
must be prevented!
•
The design of the drill is complete steel based on the requirements it
is used to work in the explosion dangerous environment.
• It is imperative to use only pressure hoses that correspond with the
NORM EN 1127-1 and EN 1127-2 par. 6.4.7, EN 13463-1 par. 4.7
(idt CLC/TR 50404:2003), ISO 80079-36 and ISO 80079-37 when
used in the classification-areas l and II.

5.5 Pneumatic Installation
This pneumatic machine may be operated with lubricated air. The best performance is
achieved by adding 1 - 2 drops oil per 1 m

Operating
Pressure
Lubrication
Before connecting the air supply line to the drill, clean the air pipe
and the air hose by slightly blowing air into the pipe/hose. This will
remove any dirt particles that are present in the pipe/hose.
Always wear safety googles, tightly hold the pipe/hose and do
not move into the air stream.
Remove the covers from the connections.
Turn the air-supply to ,,OFF".
Make sure that all air lines have a sufficient cross-section
( → “ Technical Data” ) and that there are no throttle areas, bends of
kinks. If the air supply line is longer than 2 meters, then next larger
hose I.D. should be installed in order to avoid a loss of power.
Note: the maximum length of hose is 5-meters.
The air-supply for the drill needs to be filtered (see chapter 5.6).
Do not use any Teflon tape on the threads of the pipe.
Check and make sure that the flow-pressure at the drill connection
side is 6.3 bar (90 PSI). A higher air pressure leads to increased
wear and tear (install a pressure regulator). A lower pressure
reduces the power output of the drill.
The maintenance unit, the valves and the silencers have to be
selected according to the air consumption of the machine. Install
components, which have a measurement that will limit the pressure
drop – when measured from the maintenance unit to the machine –
to less than 0.5 bar (7.25 PSI).
Fill the oil container of the oiler to the indicated oil level. Used only
lubricant DEPRAGOL INDUSTRIAL 6074291(1 liter).
The maintenance unit must be suitable for use in potentially
explosive environment.

the required speed or torque.
Adjust the oiler as described in chapter 5.6.
6.3 Measure Surface Temperature (if drill is used in an Ex-area)
The details of the maximum allowable surface temperature as
shown on the drill tag are based on measurements under normal
environmental- and installation conditions. Small changes to
those conditions (such as a constructed installation area) will
considerably effect the temperature development!
Measure
Surface
Temperature
It is very important to measure the surface temperature of the drill
during operation. Measurement can be done using conventional
temperature measuring instruments.
The surface temperature should be taken on the marked measuring
points „M1“,„M2“,„M3“ and „M4“ (see illustration 2).
The maximum allowable surface temperature is reached after approx..
1.5 hours of operation.
The maximum temperature may not exceed
•40°C for group II category 2G, IIB Gb

8 Maintenance and Upkeep
The first maintenance should be performed after 500 operating hours.
Thereafter, we recommend adjusting the maintenance intervals in accordance
with the general usage- and wear conditions of the drill, as well as the
condition of the fabrication area.
Maintenance
unit
The air drill should be regularly checked in regards to excessive noise
and/or if the gears show an increased play.
•Regularly clean filter of the maintenance unit
•Drain water condensation
•Regularly check the oil-level in the oiler and refill the oiler as needed.
Lubrication The bearings have to be sufficiently greased.
Use only lubricants approved by the manufacturer.
Bearing
Exchange
To assure a continued low surface temperature if drill is used in an EX-area,
replace the bearings after 8.000 operating hours.
Worn Vanes
Our experience has shown that the vanes (in a complete set) have to be
replaced after maximum 1000 operating hours. This interval may be longer
or shorter depending on the air quality and the fabrication conditions.
Loss of
Power
If the drill does no longer operate efficiently, the reason may be that the
vanes are clogged in the rotor-slots. This clogging is caused by the resin
residue in the oil which hinders the smooth gliding of the vanes. In such a
case, it is recommended to clean the drills‘ motor.
Seals
An insufficient seal can cause a loss of power.
If the drill is maintained on a regular basis, then the wear and tear on the
movable parts is minimal. The wear mainly depends on the air pressure and
the lubrication.
We recommend sending a failed air drill to us for repair. We have all the
necessary special repair tools for the disassembly, original spare parts and
the trained repair specialists that can adjust the drill to the correct gap play.
The gap play determines the drills power, efficiency and life expectancy.

DEPRAG
20
Maintenance and repair on hydraulic and pneumatic equipment may
only be performed by specially trained personnel!
Disconnect equipment from air supply, prior to repair of pneumatic
or hydraulic equipment.
Provide regular preventive maintenance on hoses and airlines. Exchange
hose lines, even if there is no visible damage! (Observe corresponding
requirements of the manufacturer!)
After repair and maintenance, check the following items:
•Make sure all detached and re-attached connections are solid
•Confirm that removed covers, screens or filters were re-installed.
After conclusion of maintenance or repair and prior to start of operation,
make sure to:
•Remove all materials, tools and other supplies needed for the
maintenance or repair from work area of the equipment
•Remove leaking liquid or oils
•Make sure all safety devices on the equipment work perfectly!
