Instruction manual
NOTA: the oil tank (35) has a capacity sufficient to
provide about 40 minutes of cutting time (when set
to deliver the minimum flow rate). Be sure to refill
the oil tank (35) every time you refuel the fuel tank
(12).
Adjusting oil flow rate [F9]
WARNING! Never fill oil tank (35) or
adjust the oil flow while the engine is
running.
The operation of the automatic chain lubricating
mechanism may be checked as follows:
∙
Turn on the machine and keep its tip pointing
towards a piece of cardboard or paper placed on the
ground.
WARNING! Do not touch the ground
with the saw chain (33)! Maintain a
safe distance of approximately 20 cm.
∙
If the cardboard or paper shows an increasing
amount of oil, the automatic lubricating mechanism is
working correctly. If, however, despite a full oil reservoir,
no oil traces are produced, eliminate malfunctions or
consult an authorized IVT service center.
The amount of oil to lubricate the saw chain (33) can be
adjusted with the flow rate adjusting screw (41).
1. Stop the engine and make sure the On / Off switch
(5) is in the OFF position.
2. Place the unit on its side with the oil tank (35) up.
3. With a screwdriver, push in on the oil flow rate
adjusting screw (41) and turn it. Turn the flow rate
adjusting screw (41) counterclockwise to increase the
oil feed, clockwise to decrease it.
Adjusting the tension of saw chain (33) [F10]
1. Unscrew the fixing nut (37).
2. Adjust the saw chain tension by turning the
adjusting screw (38) until the bottom of the saw chain
(33) touches the bottom of the guide bar (31).
3. Tighten the fixing nut (37) securely. Then check the
saw chain (33) for smooth rotation and correct tension
while moving it by hand.
4. Re-adjust if necessary.
OPERATING INSTRUCTIONS
Cutting techniques
(FOR THE HEDGE TRIMMER ONLY)
∙ A better cut is obtained by moving forwards slowly
and trying to keep the blade (28) slightly sloping
downwards in the cutting direction.
∙
Cut the hedge starting from the sides, leaving the
top part to the end.
∙
To obtain a uniform height for the hedge, it is
recommended to use a reference wire and cut the
branches that stick out from the wire.
∙ Cut upwards and downwards using both sides of
the blade (28), making semi-circle movements.
Vertical cut [F11]
∙ Cutting without standing directly next to the hedge,
e.g. flowerbed between operator and hedge.
∙ Swing the cutter bar up and down in an arc as you
move along the hedge – use both sides of the cutting
blades.
Horizontal cut [F12]
∙
Cutting without standing directly next to the hedge,
e.g. flowerbed between operator and hedge.
∙
Hold the cutter bar at an angle of 0° to 10° as you
swing the hedge trimmer horizontally.
∙
Swing the cutter bar in an arc towards the outside of
the hedge so that the cuttings are swept to the ground.
(FOR THE POLE PRUNER ONLY)
[F13]
To allow branches a free fall, always cut the lower
branches first. Prune heavy branches (large diameter)
in several controllable pieces.
WARNING! Never stand directly
underneath the branch you are cutting
– be wary of falling branches. Note
that a branch may spring back at you
after it hits the ground.
∙ Hold the handle housing with your right hand, and
the shaft with your left hand. Your left arm should be
extended to the most comfortable position.
∙ The shaft should always be held at an angle of 60°
or less.
∙ The least tiring working position is a tool angle of
60°.
∙ Any lesser angle may be used to suit the situation
concerned.
Cross-cut [F14]
To avoid pinching the chain in the cut, position the
