8.5 Replacement of the sawing band

Danger! Danger of injury even with sawing band at

standstill. When replacing the sawing blade, wear

gloves.

Only use suitable sawing blades

1 Release the 2 knurl screws (D) and remove the U

bracing (C) under the sawing table. (Fig. 4)

2 Open both housing doors.

3 Release the adjustment knob (9) until the sawing

blade is released.

4 Remove the sawing blade and lead it through

–the slit in the work table,

–the sawing band protection at the upper blade

guide,

–the sawing band protection at the sawing hous-

ing and the table guides.

Mount a new sawing band. Check the correct posi-

tion: The teeth must point to the front side of the saw

(where the doors are).

5 Align the sawing band to the centre of the rubber

of the band edges.

6 Tighten the adjustment knob (9) until the band no

longer slides off the edges.

7 Close both housing doors.

8 Then:

–Tighten the sawing band with adjustment knob

(9)

–Conduct a test run of at least 1 minute.

–Stop the saw, pull out the mains plug and check

the settings.

8.6 Tighten the sawing band (Fig. 8)

Danger:

Too high tension can break the band. Too low tension

can cause the driven band wheel to slip and the saw-

ing band will stop.

1 Set the upper sawing band guide (4) fully upwards.

2 Check the tension by pressing a nger halfway

between table and the upper band guide against

the side of the band. The band should not edge

down more than 3 to 5 mm.

3 If necessary, correct the tension:

–Turning the adjustment knob (9) counter-clock-

wise increases the sawing band tension.

–Turning the adjustment knob (9) clockwise re-

duces the band tension.

8.7 Alignment of the sawing band(Fig.8)

If the sawing band is no centred in the middle of the

rubber wheels the track must be corrected by adjust-

ing the incline of the upper band wheel:

1 Release the lock nut (N).

2 Turn the adjustment knob (10):

–Turn the adjustment knob (10) clockwise if the

sawing band hits the front side of the saw.

–Turn the adjustment knob (10) counter-clock-

wise if the sawing band hits the back side of

the saw.

3 Tighten the lock nut (N).

8.8 Alignment of the upper band guide (Fig. 9+10)

The upper band guide consists of:

• a compression bearing (51) (supports the sawing

band from the back side) and

• two guiding pins (53) (giving additional lateral sup-

port).

Bearing and guiding pins must be readjusted after

each band or track replacement.

Attention:

Check all bearings for wear on a regular basis. If nec-

essary replace both guide bearings at the same time.

8.8.1 Compression bearing setting(Fig. 9)

If necessary align the sawing band and tighten it.

1 Release the compression bearing adjustment

screw (50).

2 Set the compression bearing position. (51) (Dis-

tance between bearing and sawing band = 0.5

mm). If the sawing band is turned by hand it must

not touch the bearing.

(50).

8.8.2 Settings of the guiding pins (Fig. 10)

1 Release the screws (52).

2 Press the guiding pins (53) together (against the

sawing band).

3 Turn the sawing band clockwise by hand several

times in order to bring the guiding pins in the cor-

rect position - both pins should slightly touch the

sawing band.

4 Tighten the screws again (52).

8.9 Alignment of the lower sawing band guide

The lower sawing band guide consists of:

• a compression bearing (supports the sawing band

from the back side) and

• two guiding pins (giving additional lateral support).

Bearing and guiding pins must be readjusted after

essary replace both guide bearings at the same time.

band = 0.5 mm). If the sawing band is turned by

hand it must not touch the bearing.
