Working With The Tool; Care And Maintenance - Hilti WFE 380 Bedienungsanleitung

7. Working with the tool

Setting the sanding speed
The recommended sanding speed (oscillation rate) can
be pre-selected by turning the speed pre-selection thumb-
wheel to the desired setting (infinite adjustment possi-
ble). The sanding speed may also be adjusted while the
tool is running.
Sanding speed depends on the material to be sanded.
The ideal speed can be found by carrying out practical
tests (please refer to the product information provided
with the sanding sheets and to the table of applications).
Setting
Speed
After switching on, the tool then runs at the pre-select-
ed speed.
Sanding sheets
Hilti offers the appropriate sanding sheets for the appli-
cations listed under "correct use". Hilti offers the "Wood
Line" in P60 to P180 grit for all wood applications and the
"Paint Line" in P40 to P400 grit for paint applications.
Sanding plate
The sanding plate is a wearing part which is not covered
by the general warranty conditions.
The tool is fitted in the factory with a universal sanding
plate. This sanding plate achieves a very good rate of
removal and a good finish. It is equipped with dust extrac-
tion holes which combine the most important standards.
Select the most suitable sanding plate, depending on
the application.

Sanding plate brake
The tool is equipped with a sanding plate brake. The
brake ring is a wearing part which is not covered by the
general warranty conditions.
The sanding plate brake reduces the speed of the sand-
ing plate when idling so that the sander can be brought
into contact with the workpiece without risk of kick-back.

Sanding may produce hazardous sanding dust.
Sanding dust may be harmful to the lungs and eyes.
Use a dust extraction system and wear respiratory pro-
tection and protective goggles.
Dust extraction with dust box and dust bag
The dust box is a wearing part which is not covered by
the general warranty conditions.
Use the dust box with the dust bag supplied with the
tool.
Remove dust deposits thoroughly (e.g. use a vacuum
cleaner).
Dust extraction using a vacuum cleaner
In rare cases under unfavourable circumstances and in
conjunction with low air humidity, an electrostatic dis-
charge may occur when a vacuum cleaner is used for
dust extraction purposes.
This physical phenomena is not due to any technical
fault in the tool. The possibility of an occurrence of this
kind can be excluded by using the recommended Hilti
W-VC 40 vacuum cleaner. Hilti electric tools and appli-
ances comply with the presently applicable regulations.
Should you however, despite observing the Hilti system
recommendations, still experience this phenomena,
please contact your nearest Hilti service centre, provid-
ing a description of the conditions under which the tool
and appliance were used.
Remove dust deposits thoroughly (e.g. using a vacuum
cleaner).

8. Care and maintenance

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.
Sanding plate
Check the sanding plate for wear and dirt. A worn or dirty
sanding plate may result in poor attachment of the sand-
ing sheet to the sanding plate. Clean the sanding plate
or replace it if necessary (damaged sanding plates must
be replaced immediately).
