Operation without a dust collector is only possible: – outdoors; – for short use (up to max. 30 minutes); – with dust respirator. 7. Machine Details 8. Initial Operation
Page: 4
ENGLISH en 14 – If no dust collector is used chips will accumulate, which need to be removed periodically. Connect duct collector or industrial vacuum cleaner with appropriate adapter to the chip extraction nozzles (16). 8.2 Tighten band saw blade Danger! 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. 1. Quick release lever (34) must be in the "Tight band saw blade" position. 2. Move upper blade guide (39) to the very top. (For details see chapter 9.1). 3. Check band saw blade tension: Check setting on the display for the band saw blade tension (33). The scale indicates the correct adjustment depending on the band saw blade width. 4. Correct tension if necessary: – Turning the setting knob (32) clockwise increases the tension. – Turning the setting knob (32) anticlockwise reduces the tension. 8.3 Connection to Power Mains Danger! High voltage  Operate the saw in only in a dry environment.  Operate the saw only on a power source matching the following requirements (see also "Technical Specifications"): – Mains voltage and system frequency must conform to the voltage and frequency shown on the machine´s rating label; – Protection with an FI switch with an residual current of 30 mA; – outlets properly installed, earthed and tested; – three-phase outlets with neutral wire installed; Note: Check with your local Electricity Board or your electrician if in doubt whether your house service connection meets the requirements.  Make sure the power supply cable is out of the way, so that it does not interfere with the work and does not pose a tripping hazard or will get damaged.  Protect the power supply cable from heat, aggressive liquids and sharp edges.  Only use rubber cables with a sufficient cross section (3 x 1.5 mm2 as extension cables, for design with three-phase motor: 5 x 1.5 mm2).  Do not pull on the power supply cable to unplug. Change in direction of rotation (only for design with three-phase motor): Depending on phase sequence the band saw blade may turn in the wrong direction. This can cause the work piece being tossed away when attempting to cut. Therefore, always check direction of rotation after every connection to the power supply. In the case of wrong direction of rotation, the connection must be changed by an electrician! 1. When the saw is assembled and all safety devices are installed, connect it to the power supply. 2. Start saw briefly and turn OFF immediately again. 3. Note direction of rotation of the band saw blade: The band saw blade must move from top to bottom in the cutting area. 4. If the band saw blade turns in the wrong direction, unplug the power supply cable at the saw. 5. Have the electrical connection changed by a qualified electrician! Danger! To reduce the risk of personal injury as much as possible, the following safety recommendations should be observed when operating the saw.  Use personal protection gear: – dust respirator; – ear protection; – safety goggles.  Cut only one work piece at a time.  Always hold the work piece down on the table.  Do not jam any work pieces.  Do not try to slow the band saw blade down or stop it by pushing the work piece against the saw blade from the side.  If the type of work requires, use the following: – Push stick – if the distance to the stop profile – band saw blade <=120 mm; – work support – for long stock, which would otherwise fall off the table on completion of the cut; – dust collector; – an appropriate jig when cutting round stock, to keep it from turning; – a suitable guide for firm support when cutting thin stock laid on edge.  Before starting work, check to see that the following are in proper working order: – Band saw blade; – upper and lower blade guard.  Replace damaged parts immediately.  Assume correct work position (the band saw blade's teeth must point towards the operator).  Never cut several work pieces at the same time – and also no bundles containing several individual pieces. Risk of personal injury if individual pieces are caught by the saw blade uncontrolled. Entangelement hazard!  Do not wear loose clothing, jewellery, or gloves, which may get caught and wound up by revolving machine parts.  Contain long hair with a hairnet.  Never cut stock to which ropes, cords, strings, cables or wires are attached or which contain such materials. 9.1 Set height of the blade guide The height of the upper blade guide (39) must be set: – before each sawing procedure, to adjust to the height of the work piece (the upper blade guide (39) must be approx. 3 mm above the work piece during cutting); – after adjustments of band saw blade or saw table (e.g. band saw blade change, tensioning of the band saw blade, saw table alignment). Danger! Before adjusting the upper blade guide and saw table tilt: – switch machine OFF; – wait until the band saw blade has come to a complete stop. 1. Release lock nut (38). 2. Turn setting knob (37) so that the upper blade guide (39) is approx. 3 mm above the work piece 3. Retighten lock nut (38). 9.2 Set band saw speed 1. Unplug power cable; 2. Open the lower housing door. 3. Loosen drive belt by turning the setting knob (40) clockwise. 4. Place drive belts on the corresponding puller on the drive wheel (lower blade roller) and on the corresponding motor pulley – Note sticker on the inside of the lower housing door. Caution! The drive belt must run either on the two front or the two rear pulleys. Never place drive belt diagonally because otherwise it sill be damaged! – Drive belt on front pulleys = low speed, high torque (for hard wood, plastics and non-ferrous metals (with corresponding blade). – Drive belt on back pulleys = high speed, low torque (for all woods). 5. Retighten drive belt by turning the setting knob (40) anticlockwise (it must be possible to push the drive belt down about 10 mm in the middle between the rollers). 6. Close the lower housing door. 9.3 Sawing 1. Adjust the band saw blade speed. (For details see chapter 9.2). 2. If necessary, adjust the table tilt. Risk of kickback (work piece is caught by the band saw blade and thrown against the operator)! Do not jam any work pieces. 3. If necessary, use the ripe fence (26) or the fence mitre (35). Risk from tilting of work piece! When cutting with the ripping fence and inclined workpiece, the ripping fence has to be mounted at the side of the workpiece inclined downwards. 4. Tighten upper blade guide 3 mm above the work piece. (For details see chapter 9.1). 9. Operation
