Guide rail ASSEMBLY Changing the band saw blade CAUTION: • Contacting the band saw blade even with the band saw blade at standstill may cause a personal injury. • Saw blade is dangerous. Be sure to wear gloves when handling saw blade in situations such as removing from packaging, mounting or replacing blade. 1. Loosen the two thumb screws for the right-guide rail, and slide the right-side rail to the right. Thumb screws 2. Open the upper cover and lower cover on the tool. 3.
Saw blade 4. Open the lower blade guard. 5. Set the upper blade guide to its lowest position. Saw housing Upper blade guide Lower blade guard 6. Loosen quick release lever until the band saw blade has slackened. 7. To remove the band saw blade, guide it through. - the slot in the saw blade. - the blade guard on the upper blade guides. - the blade cover on the saw housing. 8. Fit a fresh band saw blade. Observe correct position: the teeth point towards the front (door) side of the saw. 9.
Cutting speed adjustment Lower band saw wheel 1. Open the lower cover. 2. Slacken driving belt by turning the knob clockwise. 3. Put driving belt on the required pulley of the driving wheel (lower band saw wheel) and the corresponding motor pulley-note label inside the lower cover.

FUNCTIONAL DESCRIPTION Tensioning the Band saw Blade Knob CAUTION: Too much tension can cause the band saw blade to break. Too little tension can cause the driven band saw wheel to slip and the band saw blade to stop. Upper blade guide 1. Raise upper blade guide fully. Using the scale as guide, and taking the blade width into consideration, turn the knob to adjust tension. (After adjusting, check tension as shown in item 2.) 2.
Quick release lever Quick release lever With the quick release lever the saw blade tension is released. Clockwise: Reduce tension Counterclockwise: Increase tension Upper blade guide adjustment Adjusting knob Lock knob The height of the upper blade guide needs to be adjusted: prior to every cutting/operation, to accommodate the height of the work piece (the upper blade guide should be set approx. 3 mm above the work piece); - after adjustments of band saw blade or saw table (e.g.
1. Loosen bolt C, and adjust bearing holder, so that guide bearing is positioned 1 or 2 mm from bottom of blade. 2. Loosen bolt A, and adjust thrust bearing to a position of 0.5 mm from rear of blade. 3. Loosen bolt B, and adjust guide bearing to a position 0.5 mm away from blade. Guide bearing Bolt A 0.5 mm 1 - 2 mm Guide bearing distance from bottom of blade Bolt C 0.
Align the lower blade guide The lower blade guide consists of: - a thrust bearing (supporting the band saw blade from the rear). - two guide bearings (providing lateral support). These parts need to be readjusted after every band saw blade change or tracking adjustment: Bolt A Thrust bearing Hex bolt Note: Periodically check thrust bearings and guide bearings for wear, if necessary replace both guide bearings at the same time. • Open lower cover door and the lower blade guard.
Lock lever Operation Danger: To reduce the risk of personal injury as much as possible, the following safety recommendations should be observed when operating the saw. • • • • • • • • • • • CAUTION: Do not touch the saw blade when cutting. During saw operation, wear safety glasses, but do not wear gloves. Cut only one work piece at a time. Always hold the work piece down on the table. Do not jam any work pieces.
Sawing WARNING: Risk of kickback (work piece is caught by the band saw blade and thrown against the operator.) Do not jam any work piece. • Select rip fence and table tilt for the type of cutting operation to be carried out. • Set upper blade guide 3 mm above the work piece. Note: Always make a trial cut in a piece of scrap to verify settings, correct if necessary before cutting the work piece. • Place work piece on the saw blade. • Plug in. • Start saw. • Cut work piece in a single pass.
Small dust collector Large dust collector (Mounted on main unit) (For changeover) How to move machine • Raise handle to enable movement of machine. • During transportation the saw band guard should be fully down and close to the table. • Do not use guarding for handling or transportation.
