Operation - Metabo BAS 317 Precision WNB Instructions D'utilisation Originales

ENGLISH
Protect the power supply cable

from heat, aggressive liquids and
sharp edges.
Use only rubber-insulated exten-

sion cables of sufficient lead
cross section (3 x 1.5 mm
machines with 3-phase motor:
2
5 x 1.5 mm ).
Do not pull on the power supply

cable to unplug.
Changing the direction of rota-
A
tion (3-phase motor only):
Depending on phase sequence the
band saw blade may turn in the
wrong direction. This can cause the
work piece being tossed away when
attempting to cut. Therefore, always
check direction of rotation after every
connection to the power supply. 
If the direction of rotation is incor-
rect, the electrical connection must
be changed by a qualified electrician!
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 imme-
diately again.
3. Check the band saw blade's direc-
tion of rotation: in the cutting area
it must run from the top down-
wards.
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!

7. Operation

Danger! 
A
To reduce the risk of personal
injury as much as possible, the fol-
lowing safety recommendations
should be observed when operating
the saw.
Use personal protection gear:

 dust respirator;
 hearing protection;
 safety goggles.
Cut only one work piece at a time.

Always hold the work piece down

on the table.
Do not jam any work pieces.

Do not try to slow the band saw

blade down or stop it by pushing
the work piece against the saw
blade from the side.
If the type of work requires, use

the following:
 push stick – if distance rip
fence – band saw blade
120 mm;

 work support – for long stock,
which would otherwise fall off
24
the table on completion of the
cut;
 dust collector;
 an appropriate jig when cut-
ting round stock, to keep it
2 from turning;
, for
 a suitable guide for firm sup-
port when cutting thin stock
layed on edge.
Before starting work, check to

see that the following are in
proper working order:
 band saw blade;
 upper and lower blade guard.
Replace damaged parts immedi-

ately.
Assume correct work position

(the band saw blade's teeth must
point towards the operator).
Never cut several work pieces at

the same time – and also no bun-
dles containing several individual
pieces. Risk of personal injury if
individual pieces are caught by
the saw blade uncontrolled.
c 
Entangelement hazard!
Do not wear loose clothing, jewel-

lery, or gloves, which may get
caught and wound up by revolv-
ing machine parts.
Contain long hair with a hairnet.

Never cut stock to which ropes,

cords, strings, cables or wires
are attached or which contain
such materials.
Upper blade guide adjustment
The height of the upper blade guide (69)
needs to be adjusted:
 prior to every cutting operation, to
accommodate the height of the work
piece (the upper blade guide should
be set approx. 3 mm above the work
piece);
 after adjustments of band saw blade
or saw table (e.g. band saw blade
change, tensioning of the band saw
blade, saw table alignment).
Danger! 
A
Before adjusting the upper
blade guide and saw table tilt:
 switch machine OFF;
 wait until the band saw blade has
come to a complete stop.
Set upper blade guide (69) with the

adjusting knob (70) to the desired
height.

Cutting speed adjustment
1. Open the lower housing door.
2. Slacken V-belt by turning the crank
clockwise.
3. Put V-belt on the required pulley of
the driving wheel (lower band saw
wheel) and the corresponding motor
pulley – note label inside the lower
housing door.
Caution! 
A
The V-belt must run either on
both front or both rear pulleys. Never
have the V-belt run diagonally!
370 m/min 800 m/min
 V-belt on front pulley 
= low speed, high torque.
 V-belt on rear pulleys 
= high speed, low torque.
4. Tighten the V-belt again by turning
the crank counter-clockwise (half-
way between the pulleys the V-belt
should flex approx. 10 mm).
5. Close the lower housing door.
