6 ENGLISH5. Do not attach a saw chain, woodcarving blade,segmented diamond wheel with a peripheralgap greater than 10 mm or toothed saw blade.Such blades create frequent kickback and loss ofcontrol.6. Do not “jam” the wheel or apply excessivepressure. Do not attempt to make an excessivedepth of cut. Overstressing the wheel increasesthe loading and susceptibility to twisting or bindingof the wheel in the cut and the possibility of kick-back or wheel breakage.7. When wheel is binding or when interruptinga cut for any reason, switch off the powertool and hold the power tool motionless untilthe wheel comes to a complete stop. Neverattempt to remove the wheel from the cut whilethe wheel is in motion otherwise kickback mayoccur. Investigate and take corrective action toeliminate the cause of wheel binding.8. Do not restart the cutting operation in theworkpiece. Let the wheel reach full speed andcarefully re-enter the cut. The wheel may bind,walk up or kickback if the power tool is restarted inthe workpiece.9. Support panels or any oversized workpiece tominimize the risk of wheel pinching and kick-back. Large workpieces tend to sag under theirown weight. Supports must be placed under theworkpiece near the line of cut and near the edgeof the workpiece on both sides of the wheel.10. Use extra caution when making a “pocket cut”into existing walls or other blind areas. Theprotruding wheel may cut gas or water pipes, elec-trical wiring or objects that can cause kickback.11. Before using a segmented diamond wheel,make sure that the diamond wheel has theperipheral gap between segments of 10 mm orless, only with a negative rake angle.Additional Safety Warnings:1. Never attempt to cut with the tool held upsidedown in a vise. This can lead to serious acci-dents, because it is extremely dangerous.2. Some material contains chemicals which maybe toxic. Take caution to prevent dust inhala-tion and skin contact. Follow material suppliersafety data.3. Store wheels as per manufacturer recom-mendations. Improper storage may damage thewheels.SAVE THESE INSTRUCTIONS.WARNING: DO NOT let comfort or familiaritywith product (gained from repeated use) replacestrict adherence to safety rules for the subjectproduct. MISUSE or failure to follow the safetyrules stated in this instruction manual may causeserious personal injury.FUNCTIONALDESCRIPTIONCAUTION: Always be sure that the tool isswitched off and unplugged before adjusting orchecking function on the tool.Adjusting depth of cutCAUTION: After adjusting the depth of cut,always tighten the lever securely.Loosen the lever on the depth guide and move the baseup or down. At the desired depth of cut, secure the baseby tightening the lever.For cleaner, safer cuts, set cut depth so that the dia-mond wheel projects 2 mm or less below workpiece.Using proper cut depth helps to reduce potential fordangerous KICKBACKS which can cause personalinjury.► Fig.1: 1.
