Storage Shears; Observations; Power Supply Batteries - Jacto PR-40 Manual De Instrucciones

a. If excessive strain occurs during cutting (Overexer-
tion). The blade is blocked because it has reached the
maximum absorption limit. While holding down the
trigger, the system will attempt to complete the cut twice
more. If the third attempt does not complete the cut,
the system will re-open the blade automatically. When
the trigger is released, the Shears are ready to start a
new cutting cycle.
b. If ongoing strain is experienced (energy balance). The
blade is blocked as the motor has repeatedly reached the
maximum output power. The cutting blade is automatical-
ly returned to the open position without further cutting
attempts, even if the trigger remains pressed, emitting
1 beep. After 2 sec. of inactivity, the Shear emits another
beep and is ready for a new re-start cycle.
c. If ongoing strain is experienced over a long period
of time. The system is in an alarm state. The blade is
blocked and it will no longer be possible to perform
other cutting cycles until the system has been returned
to safe conditions.
d. Over temperature. The blade is blocked and remains in
position until the system temperature goes below 55°C
(131°F). This protection comes into function over 60°C
(140°F) and emits 4 beeps and displays system status.
If the user performs lever or cam movements in different di-
rections, it causes mechanical overexertion beyond the limits
and protections for which the equipment has been designed.
The electronic control systems do not cover all possible faults
caused by poor or undue use.

3.9. Storage shears

The Shears should be stored clean, with the blades closed,
together with the batteries in their carrying case, protected
from moisture, cold and excessive heat. Take care to protect
the blade and counter blade with a small amount of oil to pre-
vent oxidation and after performing maintenance at the end
of work.

3.10. Observations

The Shears have an energy-saving system that turns off the
power supply from the Shears after 10 minutes of inactivity.
The Shears memorize the cuts made, average consumption
and working hours, in order to generate an activity log.
The Shears are equipped with a safety system to prevent over-
exertion. When the user tries to make the cut that is excessive
for the Shears, they will make 3 reattempts, and if cutting is not
possible the Shears will automatically return to their complete
open position. Three series of reattempts will cause the equip-
ment to stop.
lf there is insistence on cutting at the same point, the Shears
may perform a safety block (see paragraph "Protection system
in the cutting cycle").
Not all types of wood offer the same resistance to cutting; this
affects the cutting diameter or section. The maximum admis-
sible diameter for the cut will be approximately 40 mm. For
harder woods, such as orange wood, olive or similar, the maxi-
mum diameter will be that allowed by the power of the Shears
themselves.
WARNING!
• Insistence on the same cutting point with
consecutive overexertion is harmful to the
Shears. Serious faults can be caused that
affect the Shear operation. These kinds of
faults will not be covered by the warranty
or guarantee.
• The Shears are designed exclusively for
cutting wooden material. Any use to cut
materials other than wood may damage
the Shears and their cutting blade. This
damage will not be covered by the war-
ranty or guarantee.
• The use of the Shears is unadvisable in
the event of rain or excessive dew in
the crops in which the Shears are to be
used. The Shears have protection against
dampness, but their use in the rain or with
excessive humidity is not guaranteed and
can cause damage to the Shears.
• The Shears are not waterproof.
• All operation and safety events are
recorded by the Shears' electronic ma-
nagement system.

3.11. Power supply batteries

The Shears are powered by a motor operating at 48 volt DC.
The current required for operation is supplied by an external
battery to be placed in the suitable pocket in the backpack
supplied.
To charge the battery only use the standard dedicated battery
charger which is supplied with the battery pack kit.
To charge the battery is not necessary that it is completely dis-
charged.
The manufacturer does not accept responsibility for any dam-
age to the battery charger caused by use other than described.
The LED on the battery charger (Fig. 9) identifies the presence
of 100-240V (50-60 Hz) main voltage only and does not provide
any information about the charge status of the battery itself.
