Operating Conditions; Use Of The Tool - Vorel 81122 Manual Del Usuario

check the hoses and fi ttings for wear and or
damage, for any leakes. Cold air should be
pointed away from the hands.
Whenever universal screw connections i.e.
twist coupling are used (claw couplings),
safety pins and safety connectors must be
used to prevent damage to the connectors
between the hoses and between the hose
and the tool. Do not exceed the maximum air
pressure specifi ed for the tool.
Never carry the tool by holding the hose.

OPERATING CONDITIONS

It's necessary to ensure that, the source of
compressed air allows to create the proper
working pressure and it provides the required
air fl ow. In the case of a too high air pressure
, a reducer should be used together with a
safety valve. The pneumatic tool must be
powered by fi lter system and lubricator.
It will ensure, at the same time, the air which
is pure and moistured by oil. The condition
of the fi lter and lubricator should be checked
before each use, and possibly clean the fi lter
or to top up the shortage of oil in the lubrica-
tor. It will ensure proper operation of the tool
and will extend its normal service life.
In case of heavy loads always use an addi-
tional holder.
If the drill stops, for example due to jamming
or when passing through the material being
drilled, large rotational forces acting on the
tool can be triggered. It's necessary to adopt
such a posture, to be able to eff ectively coun-
teract such forces.
An unexpected tool movement or breaking of
the drill may cause injuries.
In case of the using additional holders or
supporting stands, ensure that the tool is
correctly and securely fastened.
It's necessary to adopt such a posture, which
will allow eff ectively counteract the normal or
unexpected movement of the tool caused by
the torque.
Keep body parts and clothes away from the
rotating holder and drill. There is a risk of be-
ing drawn or caught. Always ensure that all
keys and tools used to adjust and assemble
other insertion tools in the drill have been re-
moved before drilling.

USE OF THE TOOL

Before each use of the tool, ensure that no
parts of the pneumatic system are damaged. If
any damage is observed, immediately replace

it with new undamaged system components.
Before each use of the the pneumatic sys-
tem, you should dry the condensed moisture
inside the tool, compressor and other parts.
Connecting the tool to pneumatic system
The fi gure shows the recommended method
of connecting of the tool to the pneumatic
system. The method shown will ensure the
most eff ective use of the tool and will extend
the its normal service life.
Let a few drops of oil with viscosity SAE 10
into the air inlet.
To the air inlet thread securely and fi rmly
tighten screw an appropriate bit to connect
the air hose. (II)
On the tool driver mount an appropriate bit.
While working with pneumatic tools it
should be used only equipment designed
to work with the impact tools. Set the right
direction of rotation. The F stands for operate
the tool clockwise, the R stands for operate
the tool counterclockwise.
There, where it's possible, adjust the pres-
sure (torque).
Connect the tool to pneumatic system using
the hose with an inner diameter of 10 mm /
3/8". Ensure that the hose has a strength of
at least 1,38MPa. (III)
Start the tool for a few seconds making sure
that no suspicious sounds or vibrations come
from it.
Fixing the drill in the holder (IV)
Insert the drill into the holder and screw with
the key each of the 3 holes so that it is se-
curely and fi rmly fi xed in the holder. Then
remove the key from the fi xing hole.
Drilling
Adjust the pressure in the pneumatic system
so that it does not exceed the maximum val-
ue for the tool.
Set the right direction of rotation. The
F stands for operate the tool clockwise, the
R stands for operate the tool counterclockwise.
Install the additional holder, insert the brack-
et through the drill body and tighten screw
the holder. Fit the holder in a position that will
provide safe and ergonomic work. (V)
Fit a suitable drill bit in the holder.
Connect the drill to pneumatic system .
Press the switch and check that the drill /
bit does not show excessive axial run out.
If necessary, disconnect the drill from the
source of compressed air power, then re-
place the drill /bit with a new one.
