FUNCTIONS 

1. Speed change 

The drilling machine has a mechanical speed change 
incorporated (Fig.1 and 2). 
Mechanical speed change-over 

D

 is obtained by rotat-

ing the lever. The lever should not be forced when 
changing speeds. If there is any difficulty, gently rotate 
the drill spindle until the teeth engage. Mechanical 
speed change should only be carried out with the 
machine stopped. 

2. Electronic speed selection 

The machines feature dual electronic adjustment for 
torque and speed control with speed stabilisation. The 
device is specially recommended for drills with large bit 
capacity under heavy-duty conditions. 
This dual electronic adjustment feature makes it possible 
to adapt the torque and rpm settings to optimal levels as 
required by the material. 
On cast iron and high strength steels, low speed is 
advisable. 
On plastics, timber, aluminium, copper, soft bronze and 
brass, high speeds are advisable. 

3. Electronic torque adjustment 

These machines are also equipped with an electronic 
safety clutch which can be adjusted with an external 
rotary knob to control the maximum current, and thus 
indirectly control the torque setting. The user can also 
preset the maximum torque, depending on bit size, to 
prevent any twisting of arms if the tool becomes seized 
in the working material. 

WARNING! “TORQUE CONTROL”

 This machine has 

an adjustable motor torque. When it is adjusted to the 
maximum value in manual jobs, it could cause muscular 
injuries to the user. It is therefore recommended that 
position 3 on the regulation wheel is not exceeded. 
The machine is supplied to the user adjusted to posi-
tion 3. This can be changed, for example, for support-
ed work, by slightly loosening screw 1 and freeing 
arrow 2 (Fig. 6). 

4. Electronic speed control 

The machines are equipped with full wave control, which 
is adjustable by means of an external rotary knob to 
allow continuous control (step-free) of the rpm and 
ensure smooth operations. 
A speed-measuring dynamo provides feedback to en-
sure that, for each preset control value, the speed re-
mains constant for any load condition ranging from zero-
load to full power. 
The device also features gradual start-up from slow to 
full speed, thus avoiding a current peak which exceeds 
the 16A rating of the quick-blow fuses or the automatic 
short-circuit relays. 

NOISE AND VIBRATION 

This tool has been designed and made to reduce noise 
to a minimum. However, in spite of this, 

in certain 

circumstances the maximum noise level in the place 
of work could exceed 85 dBA. In this case, the oper-
ator should wear ear protection.

The machine’s noise and vibration levels, measured in 
compliance with EN 60745-1, usually reach: 

DMF23/1150VSE DMF32/1600VSE

Acoustic pressure 
(dB(A)) 90

MAINTENANCE AND CARE 

WARNING

-Always unplug the machine before carrying 

out work on it. 

-

 When you notice a decrease in hammer output, take 

the machine to an Official Service Centre. 

-

Tool inspection:

 Using a blunt cutting tool leads to 

less efficient work and could damage the motor, 
therefore cutting tools should be sharpened or re-
placed as soon as any wear is noticed. 

Daily:

 Clean 

the tool holder. 

-

Inspect the mounting screws:

 Regularly inspect all 

the mounting screws and ensure they are firmly tight-
ened. Should any screw be loose, tighten it immediate-
ly. Failure to do so could put you at serious risk. 

-

Motor maintenance:

 Take the utmost care to ensure 

that the motor winding is not damaged and does not 
become damp with oil or water.  

-

Brush replacement:

 The brushes disconnect auto-

matically and should be replaced after 150 - 200 hours 
use or when they are less than 10 mm long. Have 
them replaced by an Official Service Centre. 

-

 Clean the machine thoroughly after each use with a 

blast of dry air. 

-

 The vents of the machine should be kept clear at all 

times. 

-

 Check that the mains lead is in good condition.  If 

it is not, take it to an Official Service Centre to 
have it replaced. 

-

 Use only 

Felisatti

 accessories and spares. The parts 

the changing of which is not covered in this instruction 
manual, should be replaced in a 

Felisatti

 Official Ser-

vice Centre. 

Do not dispose of electric tools in 
the household waste! 

In accordance with European Directive 2002/96/EC 
relating to old electrical and electronic appliances and 
its translation into national law, used electric tools must 
be collected separately and recycled in an ecologically 
desirable way.
