The lower part of the guard is assembled with its upper part using the
latches (Fig. A, 14, 16). To dismantle it, the clips must be properly levered
while pulling them out of their corresponding holes. Reassembly of the
lower part of the guard is carried out by pressing the snaps into the holes.
Selecting the cutting tool for the job in hand
For mowing grass, use the line head (Fig. F, 39). For mowing overgrowth
or young trees, use the cutting disc (Fig. F, 35). It is forbidden to use the
cutting disc in areas exposed to collision with other objects.
Assembling and removing the line head
To fit the head, interlock the spindle by inserting a screwdriver into the
hole in the gearbox flange (Fig. E, 2). Then install the top stabilising ring
(Fig. G, 92), the grass wrap guard around the spindle (Fig. G, 94) and
screw the head with cutting line onto the spindle thread in sequence.
Perform disassembly in the same manner. Use the line head with the
complete guard (main part with the lower part fitted).
Assembling and removing the cutting disc
To use the device with a metal blade, remove the
lower part of the guard.
To install the cutting disc, place the upper stabilising ring (Fig. G, 92) on
the spindle, then the disc so that it rotates in the direction indicated by the
arrows on the disc (Fig. G, 93); then place the lower stabilising ring and
guard (Fig. G 94, 95) on the spindle. Lock the spindle by inserting a
screwdriver into the hole in the gear flange (Fig. E, 2), tighten the inserted
components with a nut (Fig. G, 96), make sure that the disc is seated
perpendicular to the spindle. Disassemble in the same way
Refuelling
If fuel is spilled on the appliance, do not start the
engine, carefully wipe up the area of flooding and
then wait until the fuel has completely evaporated. Do not start the
appliance where fuel has been spilled. The use of unleaded 95 petrol
is recommended.
Lay the mower on a level surface, pour the previously prepared fuel into
the fuel tank, no more than the maximum level of the tank. Use a mixture
of petrol and diesel in a ratio of 40:1. Screw the fuel tank on, make sure
the cap is tight. Store fuel only in closed canisters intended for this
purpose and marked. Store fuel for no longer than 30 days in a dry and
shaded place.
Use and adjustment of the shoulder strap
The shoulder strap should be worn ‘over the shoulder’. The upper part of
the belt should be worn on the left shoulder and the lower part (with a
snap hook) should be worn around the wearer's right hip. Adjust the
length of the belt so that the lowest part of the snap hook is at hip height.
With experience, adjust the length of the belt to make it as comfortable as
possible.
Balancing the device
To properly balance the unit, suspend it from a correctly adjusted
shoulder strap or harness, loosen the sling bolt Fig. A, 6), find a position
that allows the operator to sit comfortably and the cutting tool to rest lightly
on the ground when the unit is not held by the handlebars. Retighten the
sling bolt.
9. Switching on the device
Before starting up the unit, it is essential to carry
out the steps described in the section ‘Preparing
for operation’.
Care should be taken when starting the machine as
the working tip may rotate.
To start the machine, lay it on a flat surface so that it rests on the cutting
element guard and the fuel tank. Set the switch to the ‘I’ position (Fig. D,
1) and the suction valve lever to the appropriate position (Fig. C, 2;
closed, upper lever position when the engine is cold, open, lower lever
position when the engine is warm). Then press the fuel hand pump
bellows (Fig. C, 3) a few times (5-8 times). Pull the starter handle
vigorously, pressing the unit to the ground with the other hand. Do not
press the unit to the ground with your foot. If necessary, pull the handle
several times.
In the event of failure, switch the switch to the ‘Start’ position (it is
necessary to first depress the throttle trigger safety and the trigger itself;
Fig. D, 3, 2) and repeat the starter jerks. In case of further failure with a
cold engine, repeat the starter jerks with the suction valve open (as for a
warmed-up engine).
After starting, briefly depress the throttle trigger. When the trigger is
released, the engine should be idling and the working end should not
rotate. If this is not the case, switch off the unit and adjust the carburettor.
To switch off the unit move the switch to the ‘Stop-0’ position.
10. Operation of the device
Operation of the appliance must be carried out in
accordance with all the instructions in Chapters 2
and 3 of this manual, with due care.
Select a suitable cutting tool before starting work.
Mowing of low grass (line) and young stands (cutting disc)
Hang the device from the dedicated belt. Stand straight with a slight stride
to ensure a stable stance. Hold the cutting element just above the ground.
Carry out mowing at full speed moving the unit from right to left, then
return to the starting position and move to the next area to be mowed.
Periodically ensure that there is no debris around the cutting head that
could cause it to become blocked.
Mowing of tall grass (with line) and brush (with blade)
Hang the device from a dedicated belt or harness. Stand straight with a
slight stride to ensure a stable stance. Work at full speed. To avoid
wrapping tall plants around the cutting attachment, operate the cutting
element at a height of several centimetres below the level of the tops of
the plants, moving the unit from right to left, then return to the starting
position. Repeat until the desired effect is achieved and move to the next
area to be mowed. Do not raise the working tip above the hip line.
Periodically make sure that there is no debris around the cutting head that
could cause a blockage.
The line is subject to wear during operation, check
the length and wear condition of the line.
Automatic line feed
A convenient ‘tap&go’ system is used to unwind the cutting line.
To unwind the monofilament, tap the head against the ground so that the
monofilament release button on the underside of the head releases the
monofilament and allows it to unwind automatically.
Approximately 1cm of line will come out of the magazine on each side of
the head.
11. Ongoing maintenance
Carry out all maintenance with the rotating parts
stationary, the engine switched off and the spark
plug wire disconnected.
For safe operation and to prolong the service life of the unit, regular
servicing must be carried out under workshop conditions. Replace worn
or damaged parts to maintain operational safety. Failure to carry out
maintenance work or carrying it out incorrectly may result in a reduced
service life of the unit and, in extreme cases, an accident.
Cleaning
Clean the unit after each use to remove any lingering plant debris. For
more thorough cleaning, a slightly damp cloth can be used with a possible
addition of non-aggressive cleaning agents.
Removing the line spool
On the cutting head, push in the locking latch pull off the head collar.
There is a spool of line underneath, which must be pulled out.
Winding of the line
Each time the line is topped up, the head components must be inspected.
Do not continue to use a damaged head.
Remove the rest of the old monofilament from the spool, insert the centre
of the monofilament about 5m in length into the fixing notch so that when
it is bent 180°, it is wound in the direction of the arrows on the spool (Fig.
B). Wind the two halves of the monofilament without tangling, on opposite
sides of the spool baffle, until approximately 10cm of each part of the
monofilament is unspooled. To prevent the line from unrolling, the ends
of the line can be placed in the notches in the spool collar. It is
recommended not to use line thicker than 3mm.
Fitting the monofilament spool in the cutting head
Thread the ends of the monofilament through the monofilament holes in
the head drum, then place the spool in the head so that the arrows
indicating the direction of winding are visible, following the order of the
components i.e. washer - spring - washer - spool. Once you have ensured
that the spool is well inserted, attach the head collar.
Sharpening of metal cutting tools
The cutting disc must be inspected each time the line is replenished. It is
forbidden to continue using a damaged disc.
If there is a little wear, sharpen the tool with a file. Sharpen frequently by
collecting a small amount of material. A few strokes of the file are
sufficient to sharpen a slightly worn blade. After every 5 sharpening
operations, check the balance of the tool on a special machine or have it
checked by a specialist workshop. Sharpen severely worn cutting tools
with a sharpening device or have them sharpened by a specialised
service centre. Always check the balance of the tool after sharpening a
heavily used tool.
