5 Band Saw Setup
Blade Speed Change
To change the cutting speed, the V-belts must be changed
on the pulleys as shown in the table inside the lower
wheel housing door.
For an easy belt change a quick-action tensioning device
is provided, actuated by the handwheel (20) at the lower
right hand side of the wheel housing.
● Adjust the hex. head screw of the stop to set the table
exactly square with the blade.
● After the stop is adjusted, stick the rip fence scale (89)
to the rip fence carrier (201).
Cutting Height Setting
The upper blade guide should always be
set as close as possible against the
workpiece. To adjust, loosen the ratchet
lever and set the height with the handwheel
(27). Tighten ratchet lever after setting.
Ratchet lever operation:
To unlock the catch pull lever, it then can swivel freely.
To adjust bolt, release lever to engage catch and loosen/
tighten bolt as required.
Saw Blade Changing/Setting
This band saw is supplied with a general purpose
woodcutting blade (stock-no. 090 902 9171), installed
and set.
To change the blade start with removing the rip fence
carrier (201). Then slacken the blade tension by turning
the handwheel (16) on top of the machine housing
counter-clockwise, open both doors and swing the blade
guard out of the way. Remove blade from machine.
Install new blade and tension lightly. Turn upper band
saw wheels by hand to check tracking. The blade must
run in the centre of the wheels or else it may jump off. If
necessary, adjust tilt of upper band saw wheel with
starknob setting screw (28) at the rear of the upper wheel
housing.
If a blade of different width is installed, the guide bearing
of the upper blade guide and the pilot pins of the lower
blade guide must be adjusted so that the teeth are just
running clear of the pilot pins/guide bearings.
Blade Guiding
The blade guides of this band saw model BAS 500
provide for an exact guiding and lateral support of the
saw blade. When using narrow blades a firm guiding by
the upper blade guard is especially important. Ensure
the guide bearings (21) and the thrust bearing (76) are
set closely (to within 0.5 mm) against the blade.
The lower blade guide supports the back of the blade
with a small thrust bearing. Loosen the knurled thumb
screw (78) to adjust the thrust bearing position. Tighten
the thumb screw again. Thus the blade guide keeps the
blade from waving.
For wide band saw blades (from 13 mm/1/2 in.) the guide
bearings should not be used as, due to increased friction,
considerable heat is generated which may damage the
bearings. Retract guide bearings fully to clear the blade.
A wide blade is also thicker and strong enough to keep
it from waving.
4 Blade Speed Selection
This band saw can be set to four different cutting speeds
for best possible cutting results in different materials.
The cutting speed most suitable for the material to be cut
should be determined by making trial cuts in scrap
material.
Depending on the type of blade used and material to be
cut, the following recommendations are given:
a) 68 m/min - certain low-carbon steel, gas
aerated concrete blocks
b) 175 m/min - NF-metals and most plastics
c) 375 m/min - hardwood, certain plastics
and NF-metals
d) 967 m/min - all species of wood
For this purpose four 1/2" holes are provided in the
machine's base. Locations as per drilling pattern shown
above.

For a firm stand and vertical stability the saw must be
bolted to the floor.
