Overload Clutch; Assembly And Adjustments - BTI BH 7-45 KOFFER Traducido De Las Instrucciones Originales

The required setting depends on the bit size and hardness of
material being drilled.
• When chiselling or drilling in soft, brittle materials or
when minimum break-out is required, set the dial to a low
setting;
• When breaking or drilling in harder materials, set the dial to
a high setting.

Overload Clutch

In case of jamming of a drill bit, the drive to the drill spindle is
interrupted. Because of the resulting forces, always hold the
tool with both hands and take a firm stance. After the overload,
release and depress the trigger to re-engage drive.
Mechanical clutch
These tools are fitted with a mechanical clutch. The indication
that the clutch has activated will be an audible ratcheting
together with increased vibration.
Anti-Rotation System
In addition to the clutch, an anti-rotation system offers increased
user comfort through an on-board, anti-rotation technology
capable of detecting if the user loses control of the hammer.
When a jam is detected, the torque and speed are stopped
instantly. This feature prevents self rotation of the tool.

counterclockwise.
2. Slide the assembly onto the nose of the tool, through the
steel ring and onto the collar 2, past the chisel holder
qd
and sleeve.
3. Rotate the side handle assembly to the desired position. For
hammerdrilling horizontally with a heavy drill bit, place the
side handle assembly at an angle of approximately 20° to
the tool for optimum control.
4. Lock the side handle mounting assembly in place by
securely tightening the handle
that the assembly will not rotate.
