Tensioning the Band Saw
Blade
Danger!
Too much tension can
cause the band saw
blade to break. Too little tension can
cause the driven band saw wheel to
slip and the band saw blade to stop.
1. Raise upper blade guide fully (see
"Operation").
2. Checking the blade tension:
-Check tension by pushing with a
finger, halfway between table and upper
blade guide, against the side of the blade
(the blade should flex not more than 1-2
mm).
.
Check adjustment at the blade tension
indicator. The scale indicates the correct
adjustment in dependence on the band
saw blade width.
3. Correct tension if necessary: turning
the setting knob
(48)
counter-clockwise increases the
blade tension.
Τ
urning the setting
knob
(48)
counter-clockwise reduces
the blade tension.
6.9 Connection to Power Mains
Danger! High voltage
Operate the saw in only in
a dry environment.
Operate the saw only on a power
source matching the following
requirements (see also "Technical
Specifications"):
- mains voltage and system
frequency conform to the voltage and
frequency shown on the machine's
name plate;
-
fuse protection by a residual
current operated device (RCD) of
30 mA sensitivity;
-
outlets properly installed, earthed
and tested;
Note:
Check with your local
Electricity Board or your electrician if in
doubt whether your house service
connection meets the requirements.
- Make sure the power supply cable
is out of the way, so that it does not
interfere with the work and does not
pose a tripping hazard or will get
damaged.
-
Protect the power supply cable
from heat, aggressive liquids and
sharp edges.
-
Use only rubber-insulated
extension cables of sufficient lead
cross section (3 x 1.5 mm
2
, for
machines with 3-phase motor: 5 x
1.5 mm
2
).
-
Do not pull on the power supply
cable to unplug.
1.
When the saw is assembled and all
safety devices are installed, connect
it to the power supply.
2.
Start saw briefly and turn OFF
immediately again.
3.
Check the band saw blade's direction
of rotation:
in the cutting area it
must run from the top downwards.
4.
If the band saw blade turns in the
wrong direction, unplug the power
supply cable at the saw.
5.
Have the electrical connection
changed
by a qualified electrician
!
