4. Operating instructions

4.1 Placement and Testing

Switching ON/OFF
To turn on the machine, push the ON/OFF switch 1 in the ON
position.
To turn the machine off, push the ON/OFF switch 1 into the OFF
position.
You should be aware that the machine for safety, is provided by
the lock button switch 3 to prevent unexpected ignition.

4.2 Tool change

Removal of the saw blades (see Figure I-J-K-L)
- Unplug the saw and allow blades 6 to cool.
- Lock one of the driver flange 10 with the help of spindle lock 8
on the gear housing 15. (see Figure I)
- Unscrew lock nut 9 by rotation in counter clock wise direction.
(see Figure J)
- Open lower guard 4, with the lever 11. (see Figure K)
- Lift up and remove blade 6 B. (see Figure K)
- Lift up and remove blade 6 A. (see Figure L)
Fixing saw blades (see Figure M-N-Ñ-O)
- Lay the saw down with the lock nut 9 pointing upwards and
open the lower guard 4. Keeping it open. (see Figure M)
- Place blade 6 A (must match 3 notches) onto the flange 10 with
the text clearly visible. (see Figure N)
- Place blade 6 B onto the flange 10 with the text easily visible.
- Tighten the lock nut 9. (see Figure Ñ-O)
- Carefully turn blades 6 with your hands to be sure they easily
turn in opposite directions.
Checking and replacing the carbon brushes
The carbon brushes 7 must be checked on a regular basis.
- In case of wear, replace both carbon brushes 7 at the same
time.
- Mount the carbon brush holders.
- After mounting new carbon brushes 7, let the machine run at no
load for 15 minutes.

4.3 Setting operations

To become a longer blade 6 life time, lubrication of the blades is
necessary (bars 5 lubricants supplied), especially when cutting
aluminum, copper, stainless steel and cast iron:
- Place the wax stick 5 into the foreseen hole 14.
- Turn the feeder wheel 12 to lubricate the blades 6.
For ease of use, the handle can rotate + - 90 ° with the button 13.
Proper dosage is required. (see Figure B)
Feed speed
Feed speed is how quickly you push the saw blades 6 through the
material being cut. The correct feed speed is totally determined
by the hardness and the thickness of the material being cut.
If the feed speed is too slow the blades will only press down
the material rather then cutting it. The blade 6 edges glide an

wear down the material, what causes a poor cut and will cause
excessive wear on the blades.
If the feed speed is too fast there is a definitive risk that the cut
might split. The splinter will get bigger and bigger and eventually
break risking serious personal injury.
If the feed speed is too high there is risk that the cut might split
and the splintering opening's volume will not be sufficient to
divert all shaving. The result is poor cut with significant discharge
on the lower side of the material.

4.4 General instructions for use

Flat stirp: Move blades 6 in a 90° angle across the piece.
(see Figure C)
Aluminium / copper: Apply lubrication sticks 5. (see Figure D)
Square tube: Move blades 6 in diagonal. (see Figure E)
U profile: Move blades 6 in diagonal. (see Figure F)
Round tube: Move blades 6 through the piece making sure they
come out in a 90° angle. (see Figure G)
Thin sheet material: Slide blades 6 through the sheet.
(see Figure H)

4.5 Troubleshooting

Problem Cause
Very high spark 1. Damaged teeth
generation 2. Feed speed is too slow
3. Blunt teeth
A lot of wear in 1. Feed speed is too fast
sections 2. Damaged teeth
3. Blunt teeth
4. Not cutting parallel or
perpendicular to work
surface
Blades are breaking 1. Damaged teeth
2. Feed speed is too fast
3. Blunt teeth
4. Blades have buckled
5. Blades have burned out

5. Maintenance and service instructions

Before performing any work on the equipment, pull
the power plug.
- Thoroughly clean the whole machine and its accessories.
- Store it out of the reach of children, in a stable and secure
position, in a cool and dry place, avoid too high and too low
temperatures.
- Protect it from exposure to direct sunlight. Keep it in the dark,
if possible.
- Don't keep it in plastic bags to avoid humidity build-up.

5.1 Cleaning

- Keep the ventilation slots of the machine clean to prevent
overheating of the engine.
- Regularly clean the machine housing with a soft cloth, preferably
after each use.
