5.3. Band exchange, tensioning and adjustment
Take off the arm rear cover (see Chapter 5.2.). Loosen the tensioning handle and the tensioning wheel and thus the whole band. Take
off the band from the running wheels and out of the guide heads (see Chapter 5.4.). Insert the new band in the guide heads. Put saw
band on the running wheels and tighten the tensioning handle so that the belleville washers are pressed completely (no light shining
through them). Close the band cover, turn ON main switch or connect machine to mains and set the band speed to the minimum.
Press start button to run the band so it turns one round. Turn OFF main switch and secure the machine against running again. Open
the band cover and check if the band is correctly guided on the running wheels (see picture below). If the band is not correctly set on
the running wheels loosen the tensioning handle and with wheel swing screw correct (see picture below). Tighten the tensioning
handle again. Close the band cover. Exam the band run again. Turn OFF main switch, open band cover and check the setting of band
on the running wheels. According to need repeat this cycle till the band is set on the running wheels properly. For casual checking of
blade position can be used CONTROL HOLE OF BAND GUIDANCE. Then close the band cover turn ON main switch and make first
cut.

To achieve perfect cutting function, surface quality and workpiece correct measures, in time band exchange is needed. Blunt blade
may cause higher energy consumption, inclined cuts and cut surface roughness. One of the most important factors for band life time
and the cut quality is the band correct and enough tensioning.
Caution! It can only be done when the main switch is off and secured against switching
on again or when the machine is disconnected from the mains.
Caution! Danger of injury by the sharp band teeth. Use protective gloves. Do not touch
the guide wheels and the band.
In the case of a broken bandsaw, switch into manual mode, the switch of the lift of the arm is switched into position 1 and lift the arm
with the bandsaw above the cut material. Release the clamping unit with the CLAMPING UNIT switch into the position 0 and remove
the cut work piece outside the work table. Using the switch for the lift of the arm, switch into position 0 and after pressing the
LOWERING IN MANUAL MODE button, lower the arm approximately 20 mm above the fixed jaw and dismantle the rear cover (see
Chapter 5.2.). Replace the belt and attach the rear cover.
Note: You may use a wooden block and by tapping you can remove the sawblade out of the workpiece.
DO NOT cut the workpiece in the the same cut-groove again! The new sawblade would be damaged
too!
Caution: If the bandsaw is broken, no safety elements of the machine are
activated, the machine is under voltage, the aggregate is ON!
Caution: is a risk of injury from the sharp teeth on the bandsaw. Use work
gloves.
