Changing the rubber tires on the
blade pulleys (Fig. 17)
After a certain time the rubber tires (3) on the
blade pulleys (7,8) will get worn by the sharp
teeth of the blades and must be replaced.
Open the side cover (12).
Remove the blade (25) (see 7.7)
Lift the edge of the tire (3) with a small
screwdriver (f) and remove it from the
blade pulley (8).
Repeat for the lower blade pulley (7).
Fit the new rubber tire (3), mount the
blade (25) and close the side cover
(12) again.

Changing the table insert (Fig. 18)
To prevent increased likelihood of injury the
table insert (17) should be changed whenever
it is worn or damaged.
Dismantle the saw table (15) (see 7.2).
Push out the worn table insert (17).
Fit the replacement table insert by
following the above in reverse.

Extractor port
The bandsaw is equipped with an 100mm
extractor socket (6) for extracting sawdust and
chips.
7.13
Adjusting the blade speed (Fig. 28)
The bandsaw can be operated at two blade
speeds. To change the position proceed as
follows:
Slacken the drive belt (54) by turning
the hand wheel (4) in an anticlockwise
direction.
Move the belt to the desired position on
the belt pulley (55) and the lower blade

Figure 21.
8.3
Angular cuts (Figure 8/22)
To enable you to perform angular cuts parallel
to the blade (25), the table (15) can be tilted
forwards between 0° -45°.
Undo the fixing handle (18).
Tilt the saw table (15) forward until
required angle value has been set on
the man scale (16).
Re-tighten the fixing handle (18).
Important: When the table (15) is
tilted, place the parallel stop (23) to the
right of the blade (25) looking in the
