Figure Z101 shows the positions for drain cleaners 6.2.6.3 Operating conditions Modification: Table Z101 - Operating conditions for drain cleaners Orientation Drain cleaners are tested at no load in the forward direction The drain cleaner is held at an angle of 45° downwards from the horizontal Tool bit The drain cleaner cable is inside the drum Grip force Hold the machine with normal gripping force, at the pistol handle and the drum hand grip surface, avoiding excessive gripping force Test cycle One test cycle is given when the tool is switched on for no load at maximum speed for more than 10 s and then switched off again The measurement is conducted during 10 s within this period NOTE For drain cleaners, no load condition is the worst case for vibration Typically these tools carry m to 12 m of drain cleaner cable and a large portion of any vibration is due to the cable in the drum not running true Also, the highest speed is at idle and therefore will cause the highest vibration Little or no vibration is transmitted from the cable being in the drain since the drain cleaner cable is basically a large spring and acts as a dampener 6.2.7.2 Declaration of the vibration total value Addition: The vibration total value ah of the handle with the highest emission and the uncertainty K shall be declared ~ Classification This clause of Part is applicable Marking and instructions
