Replacing The Blade - Felco 801-HP Manuel D'utilisation

ADVICE FOR USE
• Forcing the trigger 16 does not add anything to the
cutting operation. It may lead to twisting or braking the
trigger 16 and in pruning shear 15 blockage.
• Do not move the pruning shear 15 lateraly when cutting
a branch. Failure to comply with this instruction may
result in damages to the cutting head.
• You must take all precautions to prevent the
entanglement of the pruning shear power supply
cord 02 in the branches. In order to do this, prefer
routing cord 02 along your shoulder and not around
your waist. In any case, if you wish to use the cord
around the waist, exit the cord 02 either from the top, or
from the left or right opening on the lower part of the
rucksack (depending on whether you are right- or left-
hander), then attach the cord 02 to the arm using an
arm band (ref. 800/301, available as an option at your
preferred authorized dealer), or route it under your
sleeve.
• The autonomy and useful life of the pruning shear 15
depend essentially on the right and proper adjustment
of the blade 17 and anvil blade 18. You are required to
constantly attend these items, as with a manual pruning
shear (see chapters SHARPENING, ADJUSTING THE
BLADE AND ANVIL BLADE and MISCELLANEOUS
MAINTENANCE).
• In cold or wet conditions, protect "POWERPACK
FELCO 880" carrying it under your raincoat.
• To minimize exposure to vibration of the tool, it is
advisable to pay particular attention to its maintenance
and regular sharpening.
CAUTION
During intense or heavy cutting loads, the body of the
pruning shear 15 can get hot. To avoid deterioration of the
tool, slow down the pace or intensity of the cut. In case of
problems due to high temperature, the control electronics
reduce the power of the pruning shear (see FELCO 880 user
manual, chapter "OPERATION ALARMS".
NOTES
• The pruning shear 15 familiarization process requires a
few pruning hours.
• If the cut is not performed neatly and effortlessly, it
means that the pruning shear consumes more energy
than necessary. Check the sharpening of blade 17 and
the general condition of the pruning shear 15.
• For all indications displayed by the display 08, refer to
FELCO 880 user manual.
DESCRIPTION OF THE CUTTING HEAD
See illustration on page 3.
17 Blade
18 Anvil-blade
19 Circlips
20 Connecting rod
21 Grease bolt
22 Center nut
23 Locking segment screw
24 Locking segment
25 Anvil blade screw
SHARPENING
This operation is essential because it determines the cutting
quality and the service life of the blade 17, the mechanical
components and the endurance of the battery 09.
Sharpening frequency depends of course on the wood that is
cut (hardness and diameter), the pruning rate and the
sharpening tool used (FELCO 903 is recommended).
Therefore, during the first days of use, the condition of the
cutting edge of the blade 17 must be checked regularly in
order to sharpen it at the right moment (a check every
quarter of an hour will quickly give you an idea of this
frequency). As a minimum, one daily sharpening operation is
recommended during the whole pruning season.
CAUTION
The first sharpening operation must be performed in the first
half hour. To perform this operation, refer to illustration B on
page 4 of this user manual. At this occasion check and adjust
if necessary the play between the blade 17 and the anvil
blade 18 according to the instructions "ADJUSTING THE
BLADE AND ANVIL BLADE" below.
ADJUSTING THE BLADE AND ANVIL BLADE
In order to ensure clean and precise cut, adjust periodically
the play between the blade 17 and the anvil blade 18 by
referring to the illustration C on pages 4 and 5 of this user
manual.
ADJUSTING THE BLADE AND ANVIL BLADE CROSSING
If you sharpen regularly (recommended) your blade 17 and
blade 17 does not cross correctly with the anvil blade 18, you
can extend the longevity of blade 17 by means of adjusting
its crossing with the anvil blade 18.
To do this, activate the trigger 16, 2 times quickly and hold it
to the fully actuated position. You will hear a series of 3
sound signals. Count till the 4. After the fourth, blade 17 will
advance in small increments of 1 mm (maximum 2
increments). When crossing is good (blade 17 should overlap
clearly anvil blade 18) release the trigger 16 and the tool
saves the crossing position. Only perform this operation
when blade 17 does not cross over anvil blade 18 enough.

REPLACING THE BLADE

When the blade 17 no longer crosses the anvil blade 18
throughout its length, it is recommended that you change it.
To do so, refer to the illustration D on page 5 of this user
manual.
During this operation, please check the wear on Bolt 21 and
replace it if required.
CAUTION
Never operate the pruning shear 15 during this operation, as
this may lead to the damage of the tool and personal injury. It
