Trimming Around Tree Trunks; Maintenance And Repair; Air Filter - IKRA AT 3351 A Instrucciones De Manejo

TRIMMING
The trimmer – properly equipped with protection cover
and cutting head – trims high grass, brushwood and
weeds at places that are diffi cult to access along fences,
walls, foundations and around tree trunks. The trimmer
may also be used for cutting down to the ground (e.g.,
clean-out works in the garden and in broken, thickly
covered areas).
NOTE : When trimming near foundations, stone walls
etc., even extreme care cannot avoid an increased wear
of the cutting cord.
TRIMMING / MOWING
Swing the trimmer in sickle-like movements from side to
side. Always hold the cutting head parallel to the ground.
Examine the territory and determine the desired cutting
height. Lead and hold the cutting head in the desired height
to achieve an even cutting result (Fig. 18).
TIGHT TRIMMING
Lead the trimmer straight with a slight angle in forward
direc-tion so that it moves just over the ground. Always trim
away from your body, never lead it towards the operator
(Fig. 19).
TRIMMING AT FENCES AND FOUNDATIONS
To trim at fences, posts, stone walls and foundations lead
the device slowly and carefully without letting the cutting
cord touch any obstacles. If the cutting tool encounters any
solid obstacle (stone, wall, log etc.) there is the danger of a
kickback and higher wear and tear of the cutting cord.

TRIMMING AROUND TREE TRUNKS

Lead the trimmer carefully and slowly around tree trunks
so that the cutting cord does not touch the bark. Cut
around trees from left to right. Capture grass and weeds
with the tip of the cord and slightly tilt the cutting head in
forward direction.
MOWING AWAY
When mowing away, you capture the whole vegetation
down to the ground. To do so tilt the cutting head to the
left with an angle of 30 degrees. Adjust the handle to the
desired position. Be aware of the higher danger of injuries
for the operator, surrounding persons and animals, and
the danger of damages to property through hurled-away
objects (e.g., stones) (Fig. 19).
Extending the cutting cord
To extend the cutting cord let the engine run at full throttle
and bump the cutting head on the ground. The cord is
automatically extended. The cutter at the protection cover
cuts the cord to the required length (Fig. 16).
Important note : Do not use metal wire or plastic-
sheathed metal wire of any kind in the cutting head.
This may lead to serious injuries of the operator.
ATTENTION : Regularly remove any remainders
of grass and weed to avoid an overheating of the
shaft tube. Remainders of grass and weeds get
caught under the protection cover (Fig. 17) avoiding
a suffi cient cooling of the shaft tube. Remove the
remainders carefully with a screwdriver or a similar
tool.
Replacing the cutting cord
1. Remove the screw (A) by turning it anticlockwise (Fig.
20). Use the included spanner.
2. Remove the coil (B) and spring (C) from the spindle
(D).
3. Remove the remaining cutting cord (H).
4. Fold a 5,4 m x 2 mm cord in half. Put the loop end into
the slot of the cord coil (Fig. 21).
5. Roll the cutting cord clockwise around the coil as shown
in Fig. 22. See that the cord is always tensioned and
that each half of the cord stays in the proper separate
coil box. Roll the cord up until 15cm of cord remain at
each end.
6. Lead each cord end (H) through the openings (F) at
the respectively opposite side of the coil (Fig. 23).
7. Lead the spring (C) over the spindle (D) and thread the
cord ends through the eyelets (G) in the housing (E)
(Fig. 24).
8. Lead the coil into the housing (E) while pulling the cord
ends through the eyelets (G). Make sure that the spring
is positioned correctly in relation to the coil and housing
(Fig. 24).
9. When the coil sits in its correct position in the housing,
push it fi rmly into the housing so that the spring is
tensioned. Firmly pull at both ends of the cord (H) so
that the cord cannot be pinched between the coil and
housing (Fig. 25).
10. Maintain the spring tension through continuous
pressure on the coil in the housing and fi x the screw by
turning it clockwise. Fasten the screw fi ngertight only
(Fig. 26).
11. Cut the cord to about 13cm to avoid excessive load to
the engine during the starting and warm-up phase (Fig.
7).

MAINTENANCE AND REPAIR

ATTENTION ! Always wear protective gloves when
carrying out maintenance work. Never perform
maintenance works with the engine still being
hot.

AIR FILTER

To clean the air fi lter:
1. Push the shutter (A) that holds the air fi lter, remove the
lid (B) und the fi lter (C) (Fig. 27).
2. Clean the fi lter using soap and water.
Never use petrol or benzene !
3. Let the Filter dry in the air.
4. Now put the fi lter in again proceeding the other way
round.
NOTE : Replace the fi lter if it is worn out, damaged or
too dirty.
TANK CAP / FUEL FILTER
ATTENTION : Please remove the fuel from the device
and store it in an approved fuel can, before you start
replacing these parts. Open the tank cap carefully to
allow existing pressure to slowly decrease.
NOTE : Keep the ventilating valve (A) and tank cap clean
(Fig. 28).
