A battery short can cause a large current flow, overheating, possible burns and even a breakdown. [. . . ] The clutch will slip at various torque levels when set at the number 1 to 16. Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which torque level is required for a particular application. nOTE: · The adjusting ring does not lock when the pointer is positioned only halfway between the graduations. Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. Always switch off the tool before insertion or removal of the battery cartridge. ⷠTo remove the battery cartridge, withdraw it from the tool while pressing the buttons on both sides of the cartridge. ⷠTo insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place.

Changing the direction of rotation before the tool stops may damage the tool. [. . . ] In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool. ⷠThere is a tremendous force exerted on the tool/bit at the time of hole break through. Hold the tool firmly and exert care when the bit begins to break through the workpiece. ⷠA stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out.
