Running In The Blade; Replacing The Blade - Femi N215 XL Gebrauchsanleitungen

4 USE
4.1 BLADE COOLING (Fig. 11)
Your sawing machine is equipped with an automatic blade
cooling system controlled by a motor pump A positioned
inside the tank.
Before operating the machine, prepare 12 litres of a 10%
oil-water emulsion by pouring directly the necessary oil into
the water with a temperature not lower than 10 degrees.
Agitate the mixture thoroughly and pour it in the pump
tank B.
Do not operate the machine without coolant to avoid
damage to the blade.
Use the oil specifi ed for the preparation of the coolants
(see OIL TABLE)
CAUTION: Always check that the lubrication jet is
aimed towards the blade and that its cock is not
opened too much before you put the machine in
operation.

4.2 WORKING
WARNING: Before any cutting operation, check
that all safety guards are sound and correctly
positioned.
UNIVERSAL VERSION (Fig. 8)
Switch the main switch B to position 1 so that it lights us
and the machine is ready.
INDUCTION VERSION (Fig. 3)
Press button C of main switch.
INDUCTION VERSION 2 SPEED
Select the desired speed by means of the speed variator
B provided.
Once you have completed all the procedures and operations
described so far, you may start the working processes.
To perform the cut, move to the front of the machine and
grip the handgrip with your right hand.
WARNING: Keep your left hand away from the
cutting area and on no account try to reach it
when cutting is in process.
Using the index fi nger of your right hand, press the run
button A (Fig. 4) and gradually lower the machine body until
it comes lightly into contact with the part to be cut.
Now begin to apply gradual pressure on the part and
complete the cut.
Always release button A (Fig.4) between one cutting
operation and another, while you are positioning the part.
do not try to block it or alter its functional characteristics
in any way.
If the machine suddenly stops after numerous consecutive
cuts, do not be alarmed.
The heat protector device of the motor has been activated,
breaking the power supply when the temperature of the coils
reaches the threshold limit defi ned by the insulation class,
to prevent damage to the motor.
In this case, release the button A (Fig. 4) and wait for
automatic reset which usually takes place after a few
minutes.
4.3
To obtain the best performance, the bi-metal blades fi tted
on your sawing machine must be run in for a short period.
For this reason the fi rst two or three cuts should be done
where possible on a solid piece D.70-80 mm, using a very
OIL TYPE
slight pressure on the blade, and gradually increasing
pressure in subsequent cuts.
OXALIS
To gauge the correct pressure in normal operating
SUPER
conditions defined by this manual (see cutting table),
consider for example that the fi rst cut on solid steel (eg.
EP
C40) D.80 mm should be done in about 5 minutes.
KUTWELL
After running-in, the same piece may easily be cut in about
SOLVAC
2 minutes. If the running-in process is done correctly, the
DROMUS fi nish and precision of the cut will be of better quality and
the blade will last longer.

UTENS
4.4
When you perform this operation, always wear protective
gloves to avoid contact with the teeth of the blade.
• make sure that the main switch B (Fig. 3)/(Fig. 8) is on
position 0;
• turn the handwheel B (Fig. 4) counterclockwise until the
tensioning device indicator turns off;
• loosen handles D (Fig. 4) to move the sawblade guides
E (Fig. 4) as far as they go;
• remove the guard after slackening the screws/knobs A
(Fig. 12) and lifting it from seat B (Fig. 12);
Removing the safety casing activates the safety
microswitch which automatically disables the motor
(INDUCTION VERSION ).
• fi t the new blade fi rst between the guides, then onto the
wheels;
• tighten the blade again.
Check that the back of the blade goes to rest on the bearing
inside the upper part of the machine body A (Fig. 10): if it
does not, slacken the blade slightly and move it back into
the right position.
