Adjusting the workpiece stop (fig. 5)
m For safety reasons, please disconnect the power
cable from the mains
During normal operation, the workpiece stop must
•
be secured in the lowest position.
• If the workpiece stop should butt against an obsta-
cle at the end of a cut, e.g. a wall or similar, loosen
the two screws and slide the plate upwards. Se-
cure the workpiece stop after sliding, by tightening
the two screws firmly.
Sawing process
1 Fasten the material to be sawn in a vice or an al-
ternative clamping device.
2 Bring the workpiece stop (9) in contact with the
workpiece, and whilst doing so hold the saw blade
away from the workpiece. Switch the saw on.
3 Once the saw has reached the desired speed, tilt
the main body of the tool slowly and cautiously
such that the band saw blade comes into contact
with the workpiece. Do not exert any additional
pressure, over and above the weight of the main
body of the tool. Be careful to avoid the band saw
blade coming suddenly and abruptly into contact
with the surface of the workpiece. This results in
serious damage to the band saw blade. In order to
achieve the maximum service life of the band saw
blade, ensure that no sudden impacts arise at the
start of the sawing process.
4 Straight cuts can be achieved if the band saw
blade is flush with the side surface of the motor
housing. Be aware of your viewing angle in this
case. Twisting the saw blade or holding it at an
angle causes the cut to run alongside the cutting
line, and this reduces the service life of the saw
blade.
NOTE: If the band saw becomes jammed or stuck
in the workpiece material during sawing, release
the switch immediately to avoid damage to the
band saw blade and motor.
5 The net weight of the tool delivers the most ef-
ficient downward cutting pressure. If the pressure
is increased by the operator, the saw blade be-
comes slower and the service life of the cutting
edge is reduced.
6 End pieces that are so heavy they would cause
injuries if they were to fall should be supported.
Wearing safety shoes is strongly recommended.
End pieces may be hot and sharp.
7 If possible, hold the saw tight in both hands. If only
one hand is placed on the saw during an applica-
tion, the other hand should be kept away from the
saw blade area and it is necessary to avoid the
saw falling against the clamped or supported ma-
terial after cutting.
Tips for better sawing (fig. 13)
The following recommendations should be applied
as a guideline (see table of recommended sawing
positions). The results are dependent on the operator
and the respective sawn material.
24 GB
• Never twist the band saw blade during the cutting
process.
• Never use liquid coolant with portable band saws.
The use of liquid coolants causes deposits on the
bands and reduces the capacity.
• If severe vibrations arise during cutting, make sure
that the sawn material is securely clamped. If the
vibrations continue, replace the band saw blade.
Removing the saw blade (fig. 6-11)
Attention: Pull out the mains plug!
• Rotate the saw blade tensioning lever (11) in a
clockwise direction to the stop, in order to relieve
the saw blade tension (see Figure 1).
• Turn the saw over and place it down on a work-
bench or table like this
• Loosen the screws (a) and remove the saw blade
guard (8).
• Start to remove the saw blade at the top part of
the saw blade guard (12) and continue right around
the pulleys (13). When removing the saw blade,
the tension may be relieved and the saw blade
may jump off. SAW BLADES ARE SHARP. WEAR
GLOVES WHEN HANDLING THEM (Fig. 7 + 8).
• Check the guide rollers (15) and remove all coarse
chips that may be in here. Jammed chips may pre-
vent the guide rollers from turning and lead to flat
spots.
• Rubber bands (14) are located on the pulleys (13).
The rubber bands should be checked for loose-
ness or damage with a blade change. Wipe chips
off the rubber bands on the pulleys. This extends
the service life of the bands and prevents the saw
blade from slipping.
Fitting the saw blade (fig. 6-11)
• Position the saw blade such that the teeth are on
the base and are angled in the direction of the
workpiece stop, as shown in Figure 9.
• Slide the saw blade into the guide rollers (15), as
shown in Figure 10.
• Hold the saw blade firmly in the guide rollers, run
it around both pulleys (13) and through the work-
piece stop (9)
• Make sure that the saw blade is inserted fully in
the guide rollers (15) and sits straight against the
rubber bands (14).
• Turn the saw blade tensioning lever (11) anticlock-
wise to the stop, and then turn the saw over care-
fully, so that the pulleys lie on the workbench or
table. Make sure that the teeth point away from
the band saw.
• Tighten the saw blade guard (8) again.
• Attention! Band saw must not be operated without
saw blade protection
• Switch the saw on and off a few times, to ensure
that the saw blade is sitting correctly.
m CAUTION:
• Maintain physical distance from the saw band area
during this test.
