Care
●
Used saw blades should be cleaned to remove resin
deposits at regular intervals as clean blades achieve a
much higher cutting performance. Resin deposits can
be removed by placing the saw blades in a bath of petro-
leum (paraffin, kerosene) or commercially available resin
remover.
●
Circular saw blades of the com-
posite type must no longer be used
when the remaining height or thick-
ness of the brazed-on tips is less than
1 mm.
●
The tool was lubricated adequately when it was man-
ufactured. After long periods of heavy use, it is recom-
mended that the tool is inspected at a Hilti workshop.
This will increase the life expectancy of the tool and avoid
unnecessary repair costs.
●
Repairs to the electrical section of the tool may be car-
ried out only by a trained electrical specialist.
CAUTION
Keep the power tool, especially its grip surfaces, clean
and free from oil and grease. Do not use cleaning agents
which contain silicone.
The outer casing of the tool is made from impactresis-
tant plastic. Sections of the grip are made from a syn-
thetic rubber material. Never operate the tool when the
ventilation slots are blocked. Clean the ventilation slots
carefully using a dry brush. Do not permit foreign objects
to enter the interior of the tool. Clean the outside of the
tool at regular intervals with a slightly damp cloth. Do not
use a spray, steam pressure cleaning equipment or run-
ning water for cleaning. This may negatively affect the
electrical safety of the tool.
