(18) onto the screw (20) and secure the saw
table (15).
•
To dismantle, proceed in reverse order.
5.2 Tensioning the blade (Fig. 2/5)
•
Note! You must remove the tension from the
blade when the bandsaw is not going to be
used for some time. It is important therefore
to check the blade tension before you switch
on the saw.
•
To be able to check the blade tension, open
the two side covers (12) by slackening the
fastening handles (13).
•
The correct blade tension can be tested by
applying pressure to the side of the blade
with your finger, somewhere in the middle
between the two blade pulleys (7, 8). You
should be able to deflect the blade (26) only
very slightly (approx. 1-2 mm).
•
When the blade is tensioned enough, it will
produce a metallic sound when tapped.
•
Turn the tightening screw (9) clockwise to ten-
sion the blade (26).
•
After you have adjusted the blade tension,
check the blade's running position on the two
blade pulleys (7, 8). Adjust the blade if neces-
sary (see 5.3).
•
Close the two side covers (12). Push the side
cover against the machine frame (25) as far
as it will go. The side cover must latch home
with an audible click. Screw the fastening
handle (13) tight with the side cover (12) held
in pressed position.
•
Important! Slacken the blade when you do
not want to use it for some time; this will pre-
vent it from overstretching. Turn the tightening
screw (9) approx. 3 turns counter-clockwise in
order to slacken the blade (26).
•
Warning! The blade may break if the tension
is too high.
•
Warning! If the tension is too low, the pow-
ered blade pulley (7) will simply spin without
the blade moving.
5.3 Adjusting the blade (Fig. 2/6)
•
Important! Before the blade can be adjus-
ted, it must be properly tensioned (see 5.2).
•
Open the two side covers (12) by slackening
the fastening handles (13).
•
Turn the upper blade pulley (8) slowly by hand
in clockwise direction until the blade (26) has
settled in a certain position.
•
The blade (26) should rest on the rubber tire
(3) without the blade's teeth touching the tire!
The teeth of the blade (26) should project

GB
beyond the rubber tire (3) (see Fig. 6b). If not,
the tilt angle of the upper blade pulley (8)
must be corrected.
•
Slacken the wing nut (30) in order to be able
to turn the adjustment handle (29).
•
If the blade (26) runs more towards the rear of
the blade pulley (8), i.e. towards the machine
frame (25), the adjustment handle (29) must
be turned counter-clockwise. Then turn the
blade pulley (7) slowly with the other hand to
check the position of the blade (26).
•
If the blade (26) runs towards the front of the
blade pulley (8), the adjustment handle (29)
must be turned clockwise.
•
Secure your adjustment on the upper blade
pulley (8) by tightening the wing nut (30).
•
Close the two side covers (12). Push the side
cover against the machine frame (25) as far
as it will go. The side cover must latch home
with an audible click. Screw the fastening
handle (13) tight with the side cover (12) held
in pressed position.
5.4 Adjusting the support bearing (Fig. 7-10)
•
Each time after changing the blade you must
readjust the support bearings at the lower and
upper blade guide.
•
Important! Before adjusting the support bea-
rings you must adjust the blade tension as in
5.2 and the position of the blade (26) on the
pulleys as in 5.3.
•
Important! The support bearings support the
blade (26) only during the cutting operation.
The blade should not touch the support bea-
rings in idling mode.
5.4.1 Adjusting the upper support bearings
(Fig. 7/8)
•
Adjust the upper blade guide (11) to medium
height (see 5.5).
•
Use the 4 mm hex key (57) to slacken the so-
cket head screw on the support bearing at top
left (39), right (40) and rear (41).
•
Move the support bearings (39, 40, 41) to the
point where they just stop touching the blade
(26) (max. 0.5 mm gap).
•
Re-tighten the socket head screws with the
hex key (57).
•
Important! If you fit a blade with a different
width, you can shift the complete upper bea-
ring unit (42) such that all 3 support bearings
(39, 40, 41) are shifted in one go.
•
To do so, use the 5 mm hex key (58) to
slacken the 5 mm socket head screw (43).
Move the upper bearing unit (42) to the point
