Changing The Saw Blade; Sawing Along A Line - Hilti WSC 70 Manual De Instrucciones

CAUTION
Wear ear protectors. The power tool and the sawing
operation generate noise. Exposure to noise can cause
loss of hearing.

6.1 Changing the saw blade

en
CAUTION
Wear protective gloves when changing blades. The
blade, the clamping flange and the clamping screw get
hot.
CAUTION
Check that the blade to be fitted complies with the
technical requirements and that it is well sharpened. A
sharp saw blade is an essential requirement for a perfect
cut.
6.1.1 Removing the saw blade 2
1. Disconnect the supply cord plug from the power
outlet.
2. Press the drive spindle lockbutton.
3. Turn the saw blade clamping screw with the hex.
socket wrench until the locking pin engages fully.
4. Use the hex. socket wrench to release the clamping
screw by turning it counterclockwise.
5. Remove the clamping screw from the outer clamping
flange.
6. Open the pivoting guard by swinging it to the side
and then remove the saw blade.
6.1.2 Fitting the saw blade 3
1. Disconnect the supply cord plug from the power
outlet.
2. Clean the mounting flange and the clamping flange.
3. Fit the mounting flange.
4. Open the pivoting guard.
5. CAUTION Observe the direction-of-rotation ar-
row on the saw blade.
Fit the new saw blade.
6. Fit the outer clamping flange.
7. Secure the clamping flange by tightening the clamp-
ing screw in a clockwise direction. When doing so,
press the spindle lockbutton as before (see "Re-
moving the blade").
8. Before using the power tool, check that the saw
blade is securely attached.
6.2 Adjusting the riving knife 4
Check to ensure that the riving knife is adjusted correctly.
The gap between the riving knife and the teeth of the
blade should be no more than 5 mm and the teeth should
project no more than 5 mm below the lower edge of the
riving knife.
22
The riving knife prevents the blade sticking when making
longitudinal cuts. The saw may therefore be used only
when the riving knife is correctly fitted and adjusted.
1. Disconnect the supply cord plug from the power
outlet.
2. Use a hex. socket wrench to release the hex. socket
screw.
3. Adjust the riving knife as shown in the illustration.
4. Use a hex. socket wrench to tighten the hex. socket
screw.
6.3 Adjusting the cutting depth 5
NOTE
The cutting depth should always be set to a depth approx.
5 to 10 mm greater than the thickness of the material to
be cut.
The cutting depth can be adjusted stepplessly between
0 and 55/70 mm.
1. Disconnect the supply cord plug from the power
outlet.
2. Place the power tool on a supporting surface.
3. Release the cutting depth adjustment clamping lever
The set cutting depth is indicated by the arrow on
the scale on the gear housing.
4. Lift the power tool in a scissor movement and set
the desired cutting depth by closing the clamping
lever.
6.4 Adjusting the cutting angle 6
The power tool can be set to any angle between 0 and
45º for bevel cuts. Angles of up to 50° can be set after
lifting the angle extender.
1. Disconnect the supply cord plug from the power
outlet.
2. Release the cutting angle adjustment clamping
lever.
3. Pivot the power tool into the desired position or,
respectively, lift the angle extender to allow angles
up to 50° to be set.
4. Tighten the cutting angle adjustment clamping lever.

6.5 Sawing along a line

There is a cutting line indicator for straight cuts or bevel
cuts (0° and 45°) at the front section of the base plate of
the power tool. This permits precise cuts to be made at
the selected cutting angle. The edge of the line indicator
corresponds to the inside of the saw blade. The viewing
window provides a better view of the cutting line and thus
ensures a better cut. Additional cutting line indicators are
located at the front opening for the saw blade and at the
end of the base plate.
1. Secure the workpiece so that it cannot move.
2. Position the workpiece so that the saw blade is free
to move under the workpiece.
3. Check to ensure that the switch on the power tool
is in the off-position.
