Dust Extraction; Care, Maintenance And Service - Hilti WFO 280 Manual De Instrucciones

6. Dust extraction

The dust extraction system makes it easy to
dispose of sanding dust, reduces the amount
of dust in the atmosphere and generally pre-
vents the spread of large amounts of dust. Con-
nect and use a suitable external extraction sys-
tem before beginning long periods of sanding on
wood or materials that produce hazardous dust.
Use may be made of one of two possible
dust extraction systems.
1. The built-in dust extraction system with
dust bag (fig.5)
Pull out the plastic slider 7 (located on the
underside of the grip) as far as it will go before
fitting the dust bag 6.
Fit the dust bag by pulling it over the dust
extraction connector. Ensure that the plas-
tic slider engages with the tab provided on
the dust bag.
2. Using an external dust extraction system
(fig.6)
The extraction adapter 15 must be fitted
before connecting an external extraction sys-
tem.

7. Using the sander
Disconnect the supply cord plug from
the mains socket before beginning any
work on the machine.
Sanding
The sanding finish and the speed of mater-
ial removal is determined by the sanding
sheet (grain and quality), speed setting and
the pressure applied to the sander. Switch
the machine on before bringing it into contact
with the workpiece. Position the machine on
the surface to be sanded so that the entire
sanding sheet surface is in contact with the
workpiece. Apply slight pressure to the
machine while moving it over the workpiece.
Auxiliary grip
The auxiliary grip 12 allows the sander to be
held comfortably and permits even distrib-
ution of the force applied to the machine,
particularly when a high rate of removal is
desired. Use the internal hex. socket wrench
to attach the auxiliary grip 12 to the sander.
8. Care, maintenance and
service
Always disconnect the supply cord
plug from the mains socket before begin-
ning work on the machine.
Keep the machine and the ventilation slots
2 clean at all times.
The machine is greased adequately by
the manufacturer during assembly. It is rec-
ommended that the machine is inspected at
a Hilti Service Centre after a long period of
heavy use. This will increase the machine's
life expectancy and avoid unnecessary repair
costs.
When used under extreme conditions,
heavy dirt and dust deposits may form in the
interior of the machine. In such cases, the
use of a dust extraction system and a ground
fault interrupter (residual current device) is
recommended. The machine should also be
cleaned more frequently.
Repairs may be carried out only by trained
electrical specialists.
CAUTION
Keep the power tool, especially its grip sur-
faces, clean and free from oil and grease.
Do not use cleaning agents which con-
tain silicone.
The outer casing of the tool is made from
impactresistant plastic. Sections of the
grip are made from a synthetic rubber
material. Never operate the tool when the
ventilation slots are blocked. Clean the ven-
tilation 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 running water for
cleaning. This may negatively affect the
electrical safety of the tool.
