KHE 56: Option 1 Open the clamping ring by turning the additional handle (3) anticlockwise. Secure the additional handle at the required angle. Tighten the additional handle. Option 2 Upright working position for reduced stress on the back when working on floors: The additional handle (3) can also be attached to the motor housing. Unscrew the additional handle from the handle holder (4), insert in one of the threads (9) (on the left and right of the motor housing) by hand and tighten. 8 Use 8.1 Adjusting the depth stop (only for KHE 56) Press and hold the clamp lever (5). Set the depth stop (6) to the required drilling depth and release the clamp lever. 8.2 Attaching and removing tools Before fitting tools, clean shank and apply special grease enclosed with tool (accessories order no. 6.31800)! Use only SDS-max tools. Attaching tools: Turn tool and insert until it engages. The tool is automatically locked. Pull on the tool to check that it is seated correctly.

When a chisel is fitted, only operate the machine in the chiselling operating mode . 8.5 Adjusting the impact force Slide the switch (15) to adjust the impact force (and speed) setting. Reduced impact force, reduced speed High impact force, high speed The correct setting depends on the task in hand. Example: set the switch to "reduced impact force" when working on soft, brittle material or trying to minimise break-off. Set the switch to "high impact force" when working on harder materials. 8.6 Switching On and Off Instantaneous activation: To start the machine, press the trigger switch (12). Release the trigger (12) to switch off. Continuous operation: For continuous operation, the trigger switch (12) can be locked using the lock button (11).

Therefore, always hold the machine with both hands using the handles provided, stand in a safe position and concentrate. 8.7 Metabo VibraTech (MVT) For reduced vibrations and less stress on the hands. Always apply a moderate amount of pressure to the handle when pushing down the machine and do not force. Vibrations are reduced most effectively at the central position (10). Chiselling When a chisel is fitted, only operate the machine in the chiselling operating mode . 12
