Dust Extraction; Using The Saw; Care, Maintenance And Service - Hilti WSC 55 Manual De Instrucciones

screw 11 in a counter-clockwise direction and
remove the clamping flange 12 (Fig. 3). Swing
back the pivoting guard 13, hold it securely in
place and remove the saw blade.
Fitting the saw blade (Fig. 3/5)
Note the correct direction of rotation when fit-
ting the saw blade. The teeth and the arrow print-
ed on the saw blade must point in the direction
of the arrow on the upper part of the blade guard.
Clean wood chips and other dirt or dust etc. from
the surfaces and check that the inner clamping
flange 7 is correctly seated. Fit the clamping
flange 12 and then insert and tighten the screw
11.
I Check the data for the saw blade to en-
sure that it matches the data for the machine.

4. Dust extraction

Use of a dust extraction system improves saw
dust removal performance, reduces the amount
of dust in the surrounding atmosphere and pre-
vents saw dust being spread over a wide area.
Connect the external extraction system when
you intend to work with the saw over a long pe-
riod or when materials that produce hazardous
dust are to be cut.
The extraction adapter 15 should only be left
in place on the machine when an external ex-
traction system is in use. The exit opening
may otherwise become blocked, especially when
cutting damp wood. Fit the extraction adapter
from the front, with the opening facing the rear
of the machine, and insert it into the dovetail
socket until it clicks into place. The extraction
system will be attached securely only when the
connector has been felt to click into place.
I Observe the accident prevention regulations.

5. Using the saw

I Always disconnect the supply cord plug
from the mains socket before making any
adjustments to the machine.
Sawing along a line
Rest the front part of the baseplate on the work-
piece, switch on the machine and push the
circular saw forward evenly in the direction of
the cut.
The baseplate is equipped with three cutting line
indicators 4 for 0°, 22.5° and 45°. The edge of
the cutting line indicator corresponds with the
inside edge of the saw blade.
Sawing using the parallel guide (Fig. 4)
The parallel guide 5 permits precise cuts to be
made parallel to the edge of a workpiece or,
respectively, permits strips of equal width to be
cut. To adjust the cutting width, release the clamp-
ing screw 3, adjust the guide to the required po-
sition and then re-tighten the clamping screw 3.
The parallel guide can be mounted on either side
of the baseplate in the same way.
The parallel guide may be fitted in the reverse
position (with the guide pointing upwards). In this
position, it serves to increase the width of the
baseplate.
Adjusting the cutting depth
The cutting depth can be adjusted as desired
by way of the cutting depth adjusting lever 1.
Set the cutting depth according to the scale 22.
Release the cutting depth locking device 23,
adjust as required, and then re-tighten the locking
device.
The quality of cut edges can be optimised by
ensuring that the cutting depth is set to a depth
at least 2 mm greater than the thickness of the
material being cut.
Adjusting the cutting angle (Fig. 1)
Release the cutting angle clamping screw 2 and
bring the blade to the desired cutting angle ac-
cording to the scale 21. Re-tighten the clamping
screw 2. Before bringing the baseplate back into
its original position, clean the parts to remove
wood chips or dust and dirt in order to ensure
unobstructed movement.
Plunge cutting function (Fig. 2)
Mark the section of the workpiece to be cut out.
Set the cutting depth on the saw to 0 but do
not re-tighten the cutting depth clamping screw.
Place the circular saw on the workpiece and
bring the rear mark on the baseplate into align-
ment with the line on the workpiece. In order to
reduce the risk of kick-back when starting cut-
ting, a wooden batten or similar stop can be se-
curely fastened to the workpiece in alignment
with the rear edge of the baseplate. Press the
circular saw down onto the workpiece and back
against this stop. Switch on the machine and
use the free hand to press the cutting depth ad-
justing lever 1 down smoothly until the desired
plunge cutting depth is reached. Continue the
cut until the mark at the front edge of the base-
plate meets the line on the workpiece. Switch
off the machine and lift the saw blade out of the
kerf once it has stopped rotating.
Note: Plunge cuts can be made at all angle set-
tings.
6. Care, maintenance and
service
I Always disconnect the supply cord plug
from the mains socket before beginning work
on the machine.
I Keep the machine and the ventilation slots
20 clean at all times.
Resin deposits should be cleaned from saw bla-
des at regular intervals as a clean blade im-
proves performance. Resin deposits can be re-
moved by laying the blade in a bath of paraffin
(kerosene) or a commercially available resin
solvent for 24 hours.
Should movement of the depth adjustment
mechanism become stiff, the guide posts
should be lubricated on the spot.
I The machine is greased adequately by the
manufacturer during assembly. It is recom-
mended 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.
I Repairs to electrical parts may be carried out
only by trained electrical specialists.
