MOUNTING ACCESSORIES
Fig.C
Prior to mounting an accessory always unplug the
tool.
Placing and removing bits
In addition to bits the machine can also hold screw bits
with a hexagonal shaft.
The drill head is equipped with a lock function. To
tighten or slacken the drill head, the lock has to be
unlocked first. This is done as follows:
•
Hold the drill head (A) and slide the ring (B) in the
direction of the drilling machine. The ring will jump
and the lock is now unlocked.
•
Place the shaft of the bit in the nesting place of the
drill chuck. Tighten the bit by holding ring B and
turning the drill head (A).
•
Once the bit has been tightened in, slide ring B in the
direction of the drill head, which will activate the
lock. This will stop the drill head from loosening due
to vibration during use.
•
Slide the sidegrip over the drillhead.
•
Slide the measuring rod in the sidegrip and tighten
the grip by turning the sidegrip.
•
Tighten the workpiece to a workbench by using a
clamp.
•
When all preparations are done the machine can be
connected to mains. First check if the switch is in the
‘OFF’-position and if the rotationswitch is in the
RIGHT-position.

MALFUNCTION
Below we have listed a number of possible causes and
corresponding solutions in case the machine does not
function as it should:
1. Excessive sparkling
• This usely indicates dirt in the motor or worndown
carbon brushes.
Bring your percussion drill to your Ferm-dealer.
2. The percussion drill is overheating
• The ventilationslots are covered with dirt.
Clean them with a dry cloth.
• The percussion drill is overloaded.
Use the machine for work for which it is ment to be.
Replace the drill for a sharp one or sharpen the drill by
using a benchgrinder and a twist drill grinding
