Operation - BorMann Lite Series Manual

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)
Place on the SDS-plus quick change drill chuck 1 (see Attaching the Quick Change Drill Chuck).
Clean the tool before inserting and lightly grease the insertion end.
Insert the tool with a twisting motion into the tool holder 2 until it locks.
The tool locks itself. Check the locking by pulling on the tool.
Removing SDS-plus Tools(Fig.F)
Pull the locking sleeve 5 to the rear (a), hold it in this position and remove the tool from the holder(b).
Tools without SDS-plus
Do not use tools without SDS-plus for hammer drilling or chiseling! Tools without SDS-plus and their drill are damaged by hammer drilling or chiseling.
Inserting the ToolDPlace on the ring gear drill chuck 17 (accessory)(see Inserting the Drill Chuck for Working with Tools without SDS-plus).
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.
Setting the Drilling Depth (see Fig.E)
With the depth stop 12, the desired drilling depth t can be set.
Press the button 11 of the auxiliary handle and insert the depth stop into the auxiliary handle 13 so that the grooved side of the depth stop points down-
ward.
Insert the SDS-plus tool to the stop into the tool holder 2. Otherwise, the freedom of motion of the SDS tool can lead to an incorrect setting of the drilling
depth.
Pull out the depth stop so far that the distance between the drill tip and the tip of the depth stop corresponds to the desired drilling depth t.

OPERATION

Always use the correct supply voltage!
The voltage of the power source must agree with the value given on the nameplate of the machine.
Machines designated for 230V can also be operated with 220V.
Set the Operating Mode. With the operating mode selector switch 11, select the operating mode
of the machine.Change the operating mode only when the machine is switched off! Otherwise ,the
machine can be damaged. To change the operating mode, press the locking button 10 and turn the
operating mode selector switch 11 to the desired position until it can be heard to latch.
