OPERATION
Hammer drilling operation.
First set the mode selector switch
(4) and the mode selector switch
(5) to the position shown in the fig.
3. Position the bit at the desired
location for the hole, then pull the
switch trigger. Do not force the tool.
Light pressure gives best results.
Keep the tool in position and
prevent it from slipping away
from the hole. Do not apply more
pressure when the hole becomes
clogged with chips or particles.
Instead, run the tool at an idle,
and then remove the bit partially
from the hole.
By repeating this several times,
the hole will be cleaned out and
normal drilling may be resumed.
WARNING: There is tremendous
and sudden twisting force exerted
on the tool/bit at the time of hole
break-through, when the hole
becomes clogged with chips
and particles, or when striking
reinforcing rods embedded in the
concrete. Always use the auxiliary
handle and frmly hold the tool by
both auxiliary handle and switch
handle during operations. Failure
to do so may result in the loss of
control of the tool and potentially
severe injury.
CHISELING OPERATION
First set the mode selector switch
(4) and the mode selector switch
(5) to the position shown in the fig
4. Hold the tool frmly with both
hands. Turn the tool and apply
slight pressure on the tool so that
the tool will not bounce around,
uncontrolled. Pressing very hard
on the tool will not increase
the efciency.
DRILLING OPERATION
First set the mode selector switch
(4) and the mode selector switch
(5) to the position shown in fig. 5.
Use the drill chuck assembly; you
can drill up to 13mm diameter
in metal and up to 40mm
diameter in wood.
WARNING: Never use hammer
drilling when the drill chuck
assembly is installed on the tool.
The drill chuck assembly may be
damaged. Pressing excessively
on the tool will not speed up the
drilling. In fact, this excessive
pressure will only serve to damage
the tip of your bit, decrease the
tool performance and shorten the
service life of the tool.
There is a tremendous twisting
force exerted on the tool/bit at the
time of hole breakthrough.
Hold the tool frmly and exert
care when the bit begins to break
through the workpiece.
Always secure small work pieces in
a vise or similar hold down device.
MAINTENANCE
WARNING: Always be sure
that the tool is switched of and
unplugged before attempting to
perform inspection or maintenance.
For safe and proper working, always
keep the tool and ventilation slots
clean. The tool may be cleaned most
efectively with compressed dry air.
Always wear safety goggles when
cleaning tools with compressed air.
Certain cleaning agents and solvents
damage plastic parts. Some of these
are: gasoline, carbon tetrachloride,
chlorinated cleaning solvents,
ammonia and household detergents
that contain ammonia. The brushes
and commutator in your tool have
been engineered for many hours of
dependable service. To maintain peak
efciency of the motor, we recommend
every two six months the brushes
be examined. A damaged dust cap
should be changed immediately.
We recommend having this carried
out by an after sales service.
Store the tool, operating
instructions and where necessary
the accessories in the original
packaging.
In this way you will always have
all the information and parts ready
to hand.
Changing the carbon brushes (see
Use a screwdriver to remove the
brush holder caps.
Take out the worn carbon brushes,
insert the new ones and secure the
brush holder caps.
