7.9 Replacing the blade (Figure 1,34)
Move the blade guide (11) into a position
approximately half way between the table (15)
and the machine frame (24).
Undo the fasteners (13) and open the side cover
(12).
Remove the chain bar (2).
Turn the tightening screw (9) anti-clockwise to
remove the tension from the blade (25).
Remove the blade (25) from the blade pulleys
(7,8) and take out through the slot in the table
(15).
Fit the new blade (25), aligned centrally on the
blade pulleys (7,8).
The teeth of the blade (25) must point
downwards in the direction of the table.
Tension the blade (25) (see 7.2).
Close the side cover (12) again.
7.10 Changing the rubber tires on the blade
pulleys (Fig. 35)
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 screwdriver (P)
and remove 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.
7.11 Changing the table insert (Figure 36)
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.
7.12 Extractor socket (Fig. 1-2)
The bandsaw is equipped with two extractor sockets
for extracting sawdust and chips. The equipment may
only be used with the extractor function. The
extraction channels must be checked and cleaned at
regular intervals.
Make sure that the extractor connection which is not
in use is always sealed off with the supplied caps.
7.13 Adjusting the blade speed
(Fig. 45)
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 pulley (7).
Tension the drive belt (54) again by turning the
hand wheel (4) in a clockwise direction.
Important
: Drive belts must not be tensioned
too much.
7.14 Transport
Remove the equipment from the base frame.
Transport the machine frame and the base frame
separately. Never lift the equipment by the saw table
and cover the blade with the blade guide during
transport.
8. Operation
8.1. ON/OFF switch (Fig. 37)
To turn the saw on, press the green button “I”.
To turn the saw off again, press the red button
“0”.
Your bandsaw has a switch with undervoltage
release. After a power failure you must re-
activate the switch.
8.2 Parallel stop (Fig. 38/39)
The parallel stop is used as a guide in slitting.
Place the parallel stop (23) onto the chain bar
(2) on the left or right and set the desired
dimension.
Clamp the parallel stop in the desired position
by pressing the clamping lever (27).
The chain bar can be used for thinner
workpieces as shown in Figure 38 and for
thicker workpieces as shown in Figure 39.
8.3. Angular cuts (Figure 26/40)
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 direction in which you are
working, on the side pointing downwards
(provided the workpiece is wide enough) in
order to stop the workpiece from slipping off.
