INSTALLATION
Bandsaw Blade
FIG. 33
!
WARNING! Wear protective gloves whenever you handle the bandsaw blade! On delivery a new bandsaw blade is rolled up and is in a state of high mechanical tension. Carefully unpack the bandsaw blade so that it does not fly out and cause physical injury!
Only bandsaw blades with the part number 531 0194-65 may be used. Fit the bandsaw blade as follows: 1. Remove the guards over the band wheels. The guards are attached by three rubber straps, one upper, one lower, and one in the middle. 2. Crank the band tension crank (27) anticlockwise so that the distance between the band wheels is as small as possible. 3. Loosen the crank (FIG. 33A), drop the band guard (23), and attach the bandsaw blade with the teeth facing. Make sure that the bandsaw blade enters the adjustable band guide (8) and the fixed band support (FIG. 33B). 4. Release the belt tensioner by loosening the belt idler from the engine/motor. See FIG. 34. 5. Tension the bandsaw blade using the crank (27) until the spring washers are correctly compressed. See FIG. 36A. Turn the bandsaw wheels a few turns by hand, so that the bandsaw blade centres on the band wheels. CAUTION! It is important that the bandsaw blade is not tensioned too much so that the washers are completely compressed. See FIG. 36B. The washers should have a degree of springiness to take up variations in band tension. Incorrect band tension (too hard or too loose) means that the bandsaw blade runs a risk of roaming and coming loose from the band wheel. 6. Tension the belt FIG. 35 by pulling the handle so that the idler tightens the drive belt. Lock it. A correctly adjusted belt can be moved 0.5 cm with one finger. 7. Adjust the band guide�s blocks by loosening the bolts 1 and 2 (FIG. 33). Adjust the blocks from both directions so that they lie lightly against the band. 8. Fold up the band guard (23). 9. Position the guards over the band wheels and secure them with the rubber straps. Ensure that the safety keys are in the tracks.
