WARNING! Risk of the grinding disc coming loose and causing personal injury. Ensure the power supply is connected so that the grinding disc rotates in the right direction, that is, sharpening is performed downwards-backwards. WARNING! Risk of damaging the grinding disc or bandsaw blade, which can result in personal injury. The grinding disc must not be running during the procedure set out in points 8-11 below.

7. Start the feed with the power switch (49). The feed cam wheel (K) should rotate anticlockwise. If this is not the case, the connection cables have been interchanged. 8. Stop the feed and check where the grinding disc goes down against the bandsaw blade. 9. Adjust the knob (L) until the grinding disc just touches the inside of the saw tooth (M). Points 7 and 8 above may need to be repeated. 10. Insert the lifter (N) in the appropriate hole in the lever (O) and start the feed. Adjust the knob (P) until the grinding disc just touches the entire tooth valley while fed. 11. Stop the feed and turn both knobs 1/2 turn anticlockwise. CAUTION! Do not grind to heavily. This can destroy the hardening of the teeth. Each turn of the adjuster screws corresponds to a grinding depth of 0.75 mm. The maximum grinding depth per sharpening is 0.1-0.2 mm. If the bandsaw blade is very worn, grind several times.
