h) Move the piston to its outermost position, start
and stop the motor several times (before the pis-
ton automatically returns).
i) Complete filling.
j) Fit the oil cover and tighten it.
See figure 5.
Filling hydraulic oil:
Before removing the magnetic cover to check the oil
level, make sure that the piston is in its outermost
position - pull it out if necessary. Failure to do so
may cause the hydraulic oil to leak, air bubbles to
form and/or the oil level to be measured incorrectly,
causing the machine to malfunction.
Proceed as follows, only after having carried out the
steps above:
1. Position the machine horizontally in a stable po-
sition on a work surface with the magnet cover
facing upwards. Place a container under the
machine to catch the oil.
2. Unscrew the magnetic cover (see part 6 in Sec-
tion 8) and remove any residue.
3. Check the amount of oil that is missing.
4. Slowly fill up to the top of the hole with the re-
commended new and clean oil using suitable
equipment (such as a funnel).
5. Fit the oil cover and tighten it.
Maximum oil volume: 0,3 l
Hydraulic oil type:
ESSO NUTO 46 or equivalent approved oil HLP46
according to the DIN 51 524 MIL-H 17672 C stan-
dard.
When discarding the machine or any of its parts (oil,
plastic, etc.), follow the applicable regulations in the
relevant country.
2. Checking screws
Check periodically - or daily if work is frequent or
prolonged - and make sure that all screws are pro-
perly tightened.
FAILURE TO TIGHTEN THE SCREWS MAY RE-
SULT IN SERIOUS INJURY.
3. Checking the blades
Damaged blades reduce the tool’s performance and
cause the electric motor to overheat.
Replace worn blades immediately.
Replacing the movable blades:
a) Loosen the two locking screws (A) in fig. 6.1 and
remove the protective cover.
b) Loosen the side screws (B) in fig. 6.2 which se-
cure the spring in the movable blade.
c) Remove the nut and washer (C) and pull out the
pin (D) in fig. 6.3.
d) Remove the movable blade (E) in fig. 6.4.
e) Fit the new movable blade, secure it with the pin
(D) and the nut with washer (C) in fig. 6.3.
f) Tighten the nut and washer (C) so that the
movable blade can move freely up and down
and vice versa.
g) Attach the two screws to the piston (B) with th-
read adhesive (Loctite).
h) Refit the protective cover.
Replacing the fixed blades:
a) Repeat the instructions for the movable blades
from step a) to d) and then proceed as follows.
b) Remove the nut and washer (H) and pull out the
pin (F) in fig. 6.6.
c) Remove the fixed blade (J) in fig. 6.6.
d) Fit the new fixed blade, secure it with the pin (I)
and the nut with washer (H) in fig. 6.6.
e) Repeat the instructions for the movable blades
from step e) to h).
4. Hydraulic components
a) Cleaning the piston
KEEP THE PISTON HEAD CLEAN TO PREVENT
INCOMPLETE RETURNS AT THE END OF THE
CYCLE, OTHERWISE A NEW CYCLE WILL NOT
START.
Proceed as follows in the event of malfunctions
caused by built-up dirt on the piston head (figure 7):
• Place the machine horizontally on a stable
work surface.
• Remove the cover by loosening the two
screws on the sides.
• Put the piston B back in its innermost position
using a lever.
• Clean piston head A.
b) Adjusting the stroke of the upper moveable
blade
To increase the stroke of the upper blade, move
the adjusting screw under the cutting head drive
cam as follows:
• Move the piston fully back to its innermost
position.
• Place the machine horizontally on a stable
work surface.
• Loosen the two locking screws (A) in fig. 6.1
and remove the protective cover.
• Remove the two side screws that hold the
spring on the upper blade in order to access
the cam. (B) i fig. 6.2.
• Move the piston forward and remove the cam
(fig. 6.4).
• Use a screwdriver to turn the set screw
anti-clockwise to increase the stroke; make
sure that the piston does not turn.
• Make very small adjustments to prevent the
blades from overlapping each other and get-
ting stuck.
• Fit the cam and fasten the screws and the
spring, taking care not to tighten the screws
