Hammer drilling
1. In principle, masonry should be drilled in hammer drilling mode with
maximum speed. However, in the first few seconds, the drill bit may
deviate from the original desired position due to the hammer action.
To avoid this, use inching mode to the On/Off switch until the drill bit
tip is well seated in workpiece.
2. Pay special care when drilling tiles. Hammer drilling can damage the
tile! Use special tile drill bit with drill mode without hammer function to
drill through the tile first! Then switch to hammer drilling mode for the
brick/concrete behind the tile.
1. Always hold the product perpendicular to the point to be drilled. Holding it at an
angle may cause slipping or jamming of the drill bit. See Fig. F, G.
2. Always place the drill tip directly on the point to be drilled first and then switch the
product on.

Chiselling
• Choose a suitable SDS-Plus chisel for your application.
• Use shorter chisel when a big striking power is required.
• Mark the chiselling route when you plan to chisel slots.
• Start near the edge and then proceed towards the inside.
05
Torque limiter
The product is designed with a clutch unit. The torque limiter will be activated
automatically when the product reaches a certain torque. In this case, the attachment
stops working as soon as the torque limiter turns on. Release the on/off switch and
remove the attachment from the drill chuck to avoid wear or damage.
After use
• Switch the product off, wait for complete stop, disconnect it from the power supply,
let it cool down and remove the drill bit.
• Check, clean and store the product as described below.
