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:

DMF23/1150VSEDMF32/1600VSE

coustic pressure

(dB(A)) 90 86

Sound-power level

(dB(A)) 103 99

Use ear protection!

Vibration acceleration

(m/s

) 4.5 4.1

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.
