Safety instructions
Important information for safer drilling
and tapping
This manual follows the EC Machines Directive
(98/37/EEC) regarding operator's instructions and
relevant parts of standards from CEN TC 255 "Hand-
held power driven non-electric tools – Safety".
These instructions concern operation, handling of
machine, inserted tool and equipments as well as
maintenance.
Neglect to follow these long established recom-
mendations may cause serious hazards.
Make sure that the operator has fully understood
the following recommendations and has full access
to them.
T pay strict attention to following measures the
operator has to take in order to avoid risks
of misuse or accident
Installation
Follow the instructions for air preparation given in
the written instructions supplied with the machine.
When lubrication is recommended – use recom-
mended lubricants only.
Check hose size and air pressure.
Avoid the risk of whipping hose – regularly check
hose, hose fitting and clamp conditions.
Check that the exhaust air is directed to avoid
blowing dust or air from the work piece onto the
operator or other persons. Arrange for barriers if
possible.
When necessary, use exhaust hose and arrange for
dust collection.
A
Pneumatically driven power tools are not
generally insulated for coming into contact
with electric power sources.
Explosive atmosphere must not be ignited –
to prevent injury and property loss from fire
use other non sparking process.
Choose insert tools according to the application,
power and speed of your machine.
Use sharp drill bits to avoid breakage or seizing
in hole.
If the machine is suspended by a balancer – regu-
larly check the condition of hooks and suspension
yoke.
Avoid accidents when using the machine
To prevent vision loss - always wear impact resist-
ant eye protection.
Isolate work by using barriers between work sta-
tions
Before using the power tool, check that the throttle
safety latch (if any) is working and that the tool stops
when releasing trigger.
Remove chuck keys and wrenches immediately
after use.
To avoid injury from touching rotating inserted
tool – disconnect power tool from air supply when
changing inserted tool or any adjustment operation.
Mind your hands, hair, clothing and jewellery –
always keep well away from rotating parts and cut-
ting edges.
Don't point at other persons – drill the work ...
not people.
Use clamp or vice to hold the workpiece during
operation.
Predrill slightly larger than core diameter of final
drill to increase rate of material removal and to
minimize reaction force when breaking through.
Keep proper footing and balance at all times –
stand alert for unexpected tool reaction or breakage
of inserted tool.
Use a support handle to take up static reaction
force and sudden reaction when breaking through,
particularly when drilling holes larger than 6.5 mm
in metal.
For heavy screw feed drills support handle or re-
action bar must always rest against a fixed point.
Spindle torque is high and may break an arm or leg
when drawn in or trapped.
When drilling in unknown areas and walls proceed
with extreme care. Be alert for hidden gas, water and
electric lines.
If the energy supply is broken – immediately re-
lease throttle.
When not using the machine lay it aside in such
a way that the risk of unintentional start or other
people getting injured by the inserted tool is minim-
ised.
Long term risks when using the machine
To prevent gradual loss of hearing due to expos-
ure to high noise levels – wear ear protection if the
tool itself or the process generates a high noise.
Vibration may be harmful to hands and arms
– reduce total time of exposure to vibration caused
by improperly working drill bits or other inserted
tools.
Avoid inhaling dust resulting from drilling op-
eration.
The dust may be harmful to health.
Use a dust extraction system or an approved dust
mask when necessary.
