34、conditions shown in Table Z101. Table Z101 Test conditions Orientation Cutting grooves in a horizontal piece of medium density fibreboard (MDF) having the minimum dimensions 400 mm (length) x 400 mm (width) x 30 mm (thickness). The board is fixed to a work bench by screws or clamps with a resilient

35、material between bench and workpiece. Tool bit Disc cutter with 4 mm thickness specified for MDF Feed force As necessary for working smoothly without overloading the machine. Apply equal force to both handles avoiding excessive gripping forces. Test cycle One test cycle consists of cutting a single

36、groove 4 mm wide and 12 mm deep into an edge of the MDF not less than 400 mm in length.

Disc cutters running over rated sp

41、eed can fly apart and cause injury. NOTE The term “disc cutter” may be replaced by other terms to reflect regional differences. Always use the guard. The guard protects the operator from broken disc cutter fragments and unintentional contact with the disc cutter. NOTE The term “disc cutter” may be r

42、eplaced by other terms to reflect regional differences. Hold power tool by insulated gripping surfaces, because the cutter may contact its own cord. Cutting a “live“ wire may make exposed metal parts of the power tool “live“ and could give the operator an electric shock. !“BS EN 60745-2-19:2009+A1:2

Add

46、itional subclauses: 19.101 Disc cutter guard A jointer shall be provided with a guard that automatically retracts to the closed position when not in use. There shall be no provision for locking the guard in the open position. The guard shall be so constructed that it stays in contact with the work p

47、iece when the tool is retracted, or when released from its full open position, it shall retract to its fully closed position. BS EN 60745-2-19:2009+A1:2010EN 60745-2-19:2009+A1:2010 (E) 8 Compliance is checked by inspection, and by the following tests: One sample of the tool is to be conditioned by

48、cycling the guard from the fully closed position to the maximum open working position and then releasing for 50 000 cycles at a rate not less than 10 cycles per minute. Following the cycling, the tool is oriented with the weight of the tool in a direction causing the guard to open. The disc cutter s

49、hall not be accessible to a straight edge applied perpendicular to the disc cutter. The sample or a second sample at the manufacturers option is to then be conditioned by making 50 plunge cuts into soft wood that has been stored indoors for 72 h prior to the sawing. The tool is then conditioned for 24 h in a relative humidity of (90 50+) % and at a temperature of (32 2) C. The tool need not be conditioned by wood cutting if the accumulation of saw dust will not affect the
