Inserting/Replacing the Tool
Take care when changing tools that the dust
protection cap (4) is not damaged.
SDS-plus Tools
The SDS-plus tool is designed to be freely
movable. This causes eccentricity when the
machine is not loaded. However, the drill
automatically centers itself during operation.
This does not affect drilling precision.
Inserting a SDS-plus Tool, (see Fig. C)
Clean the tool before inserting and lightly
grease the insertion end.
Insert the tool with a twisting motion into the
tool holder (3) until it locks.
The tool locks itself. Check the locking by
pulling on the tool.
Removing SDS-plus Tools, (see Fig. D)
Pull the locking sleeve (5) to the rear (a), hold
it in this position and remove the tool from the
tool holder (b).
Tools without SDS-plus
Do not use tools without SDS-plus for hammer
drilling or chiselling!
Tools without SDS-
plus and their drill chuck are damaged when
hammer drilling or chiselling.
Inserting the Tool
Place on the ring gear drill chuck (17).
Turn the sleeve of the ring gear drill chuck in
the counter clockwise direction until the tool
holder is open wide enough. Insert the tool in
the middle of the tool holder and clamp with
the drill chuck key uniformly in all three holes.
Tool Removal
Turn the sleeve of the ring gear drill chuck with
the aid of the drill chuck key in the counter
clockwise direction until the tool can be
removed.
