Use of a cord suitable for outdoor use reduces the risk of electric shock. f. If operating a power tool in a damp location is unavoidable, use a PRCD or ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock. WWW.DIAQUIP.CO.UK... - Page 4 Loose clothes, jewellery or long hair can be caught in moving parts. g. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

- Page 8 Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards. p. Do not operate the power tool near flammable materials. Sparks could ignite these materials. WWW.DIAQUIP.CO.UK...
- Page 9 Do not “jam” the wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage. WWW.DIAQUIP.CO.UK...
- Page 10 Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. j. Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
