Operation; Changing The Saw Blade - Hilti WSC 70-A36 Bedienungsanleitung

7 Operation

NOTE
If the blade is stalled for a long time, the tool will not
restart by itself when the pressure applied to it is released.
The switch-on interlock and the on/off switch must be
pressed again.
CAUTION
Wear protective gloves. The cutting edges of the saw
blade teeth are sharp. The cutting edges may present a
risk of injury.
CAUTION
Wear protective glasses and a dust mask. The sawing
operation swirls up dust and wood chips into the air. The
dust and wood chips may be harmful to the eyes and
respiratory system.
CAUTION
Wear ear protectors. The power tool and the sawing
operation generate noise. Exposure to noise can cause
loss of hearing.

7.1 Changing the saw blade

CAUTION
Wear protective gloves when changing insert tools.
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.
7.1.1 Removing the saw blade 2
1. Pull the battery out of the power tool.
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.
7.1.2 Fitting the saw blade 3
1. Pull the battery out of the power tool.
2. Clean the mounting flange and the clamping flange.
3. Fit the mounting flange.
4. Open the pivoting guard.
CAUTION Observe the direction-of-rotation ar-
5.
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.
7.2 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.
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. Pull the battery out of the power tool.
2. Release the hex. socket screw with a hex. socket
wrench.
3. Adjust the riving knife as shown in the illustration.
4. Tighten the hex. socket screw with a hex. socket
wrench.
7.3 Adjusting the cutting depth 5
NOTE
The cutting depth set should always be 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 70 mm (2⁵/₈").
1. Pull the battery out of the power tool.
2. Place the power tool on a supporting surface.
3. Release the cutting depth adjustment clamping lever
The depth set can be read from the scale at the
arrow on the guide.
4. Lift the power tool in a scissor movement and set
the desired cutting depth by closing the clamping
lever.
7.4 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. Pull the battery out of the power tool.
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.
