Direction of rotation R / L
The machine is able of running in both right and left direction. Sense of rotation can be changed using
the rotation direction switch (11) located above the main switch. Always wait until the machine stops
before changing the rotation direction.
•
Right run: for drilling and screwing in.
•
Left run: for unscrewing only.
Note:
When using left run, tighten the chuck extra firmly to prevent it from coming loose. Do not use left
run when drilling, because the drill bit would get damaged.
Drilling / impact drilling
The machine can drill either with impact or without impact. Impact drilling is recommended for concrete,
masonry and stone. Always wait until the machine stops before switching between drilling and impact
drilling.

Working instructions:
•
Always choose the correct type of drill bit for the worked material.
•
For steel use perfectly sharpened bits made of high speed steel.
•
Avoid overheating of drill bits by letting them cool down during stops.
•
For tile start drilling without impact and once the drill has penetrated the tile, continue with impact.
•
For screwing/unscrewing use low rotation speed and drilling mode only.
•
When drilling large diameter holes, it is better to pre-drill the hole with a smaller diameter drill bit.
