SAFETY RULES
Basic Safety Precautions
• Read this manual carefully until you completely understand and
can follow all safety rules, precautions, and operating instructions
before attempting to use the unit.
• Restrict the use of your hedge trimmer to adult users who
understand and can follow safety rules, precautions, and operating
instructions found in this manual. Minors should never be allowed
to use a hedge trimmer.
• Do not handle or operate a hedge trimmer when you are fatigued,
ill, or upset, or if you have taken alcohol, drugs, or medication. You
must be in good physical condition and mentally alert. Hedge
trimmer work is strenuous. If you have any condition that might be
aggravated by strenuous work, check with your doctor before
operating a hedge trimmer (Fig. 1). Be more cautious before rest
periods and towards the end of your shift.
• Keep children, bystanders, and animals a minimum of 35 feet (10
meters) away from the work area. Do not allow other people or
animals to be near the hedge trimmer when starting or operating
the hedge trimmer (Fig. 2).
• While working with the hedge trimmer, always use safety protective
approved clothing. The use of protective clothing does not
eliminate injury risks, but reduces the injury effects in case of
accident. Consult your trusted supplier to choose equipment in
compliance with legislation. The clothing must be proper and not
an obstacle. Wear adherent anti-cut clothing. Protective jackets
(Fig.3) and dungarees (Fig.3) are ideal. Do not wear clothes,
scarves, ties or bracelets that can stuck in to twigs. Tie up and
protect long hair (example with foulards, cap, helmets, etc.). Safety
boots having skid-proof sole and anti-piercing insert (Fig.4).
Wearprotectivegogglesor facescreens(Fig.5)!.Useprotections
against noises: for example noise reduction ear guards (Fig.4)
or earplugs. The use of protections for the ear requests much more
attention and caution, because the perception of danger audio
signals (screaming, alarms, etc.) is limited. Wear gloves (Fig.6,
page 8).
• Only loan your hedge trimmer to expert users who are completely
familiar with hedge trimmer operation and correct use. Give other
users the manual with operating instructions, which they have to
read before using the hedge trimmer.
• Check the hedge trimmer each day to ensure that each device,
whether for safety or otherwise, is functional.
• Never use a damaged, modified, or improperly repaired or
assembled hedge trimmer. Do not remove, damage or deactivate
any of the safety devices. Always replace blade, hand guard
immediately if it becomes damaged, broken or is otherwise
removed.
• Carefully plan your working operation in advance. Do not start
cutting until you have a clear work area, secure footing.
• All hedge trimmer service, other than the operations shown in the
present manual, have to be performed by competent personnel.
• The hedge trimmer must only be used to trim hedges or small
bushes. It is forbidden to cut other types of material. Do not use the
hedge trimmer as a lever to lift, move or break objects, nor lock it
on fixed supports. It is forbidden to apply tools or applications that
are not the ones indicated by the manufacturer onto the hedge
trimmer’s power take-off. Do not use it for pruning trees or cutting
grass. It is unadvisable to cut other types of material.
• It is unadvisable to hitch tools or applications to the P.t.o. that are
not specified by the manufacturer.

SAFETY RULES
Precautions to Reduce Vibration Risk
• The hedge trimmer is provided with anti-vibration (AV) system; never alter or modify it.
• Wear gloves and keep your hands warm.
• Keep the blade sharp and the hedge trimmer, including the AV system, well maintained. A dull blade will increase
cutting time, will increase the vibrations transmitted to your hands.
• Maintain a firm grip at all times, but do not squeeze the handles with constant, excessive pressures, take
frequent breaks. All the above mentioned precautions do not guarantee that you will not sustain whitefinger
disease or carpal tunnel syndrome. Therefore, continual and regular users should monitor closely the condition
of their hands and fingers. If any of the above symptoms appear, seek medical advice immediately.
Maintenance Precaution
WARNING: Never operate a hedge trimmer that is damaged, improperly adjusted, or is not
completely and securely assembled.
• Be sure that the blade stops moving when the throttle control trigger is released. If the blade moves at idle
speed, the carburetor may need adjusting, see Operation-Carburetor Adjusting Section. If the blade moves at
idle speed after adjustment has been made, contact a Servicing Dealer for adjustment and discontinue use until
the repair is made.
WARNING: All hedge trimmer service, other than items in the Operator's Manual maintenance
instructions, have to be performed by competent hedge trimmer service personnel. (If improper
tools are used to remove the flywheel or clutch, or if an improper tool is used to hold the
flywheel in order to remove the clutch, structural damage to the flywheel could occur which
could subsequently cause the flywheel to burst and serious injury could result.)
• Never modify your hedge trimmer in any way.
• Keep the handles dry, clean, and free of oil or fuel mixture.
WARNING: Use only accessories and replacement parts recommended.
• Never touch the blade or attempt to service the hedge trimmer while the engine is running.
• Never use fuel for cleaning operations.
• Keep the hedge trimmer in a dry place, off the ground with the blade cover on and the tanks empty.
• If your hedge trimmer is no longer usable, dispose of it properly without damaging the environment by
handing it in to your local Dealer who will arrange for its correct disposal.
• Replace immediately any safety device when damaged or broken.
WARNING: The muffler and other parts of the engine (e.g. fins of the cylinder, spark plug)
become hot during operation and remain hot for a while after stopping the engine. To reduce
risk of burns do not touch the muffler and other parts while they are hot.

OPERATION
Fueling (Do Not Smoke!) (Fig. 21)
This product is powered by a 2-cycle engine and requires pre-mixing
gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-cycle
engine oil in a clean container approved for gasoline (Fig. 19).
RECOMMENDED FUEL: THIS ENGINE IS CERTIFIED TO OPERATE ON
UNLEADED GASOLINE INTENDED FOR AUTOMOTIVE USE WITH AN
OCTANE RATING OF 89 ([R + M] / 2) OR HIGHER (Fig. 20).
Mix 2-Cycle Engine Oil with gasoline according to the instructions on
the package. We strongly recommend the use of 2% (50:1) Efco Two
Cycle Engine Oil, which is specifically formulated for all Efco air-
cooled two-stroke engines.
The correct oil / fuel proportions shown in the table below are
suitable when using the Efco Two Cycle Engine Oil or an equivalent
high-quality engine oil (JASO specification FD or ISO specification
L-EGD). When oil specifications are NOT equivalent or unknown use
4% (25:1) fuel / oil mixing ratio.
CAUTION: DO NOT USE AUTOMOTIVE OIL OR 2-CYCLE
OUTBOARD OIL.
CAUTION:
- Match your fuel purchases to your consumption; don’t
buy more than you will use in one or two months;
- Store gasoline in a tightly-closed container in a cool,
dry place.
CAUTION - For the mixture, never use a fuel with an
ethanol percentage higher than 10%; gasohol (mixture
of gasoline and ethanol) up to 10% ethanol or E10 fuel
are acceptable.
When using an Oxygenated Gasoline a good practice of Fuel
Management is necessary.
Gasoline Oxygenated with alcohol readily takes/up water when it is
present; the water may be condensed out of humid air or be a
contaminant in the fuel system, including tank.
The use of Oxygenated Gasoline may cause the occurrence of vapor-
lock easier.
NOTE - Prepare only the quantity of mixture required for immediate
use; do not leave fuel in the tank or a container for a long time. Were
commend the use of the additive Emak ADDITIX 2000 code
001000972 if the mixture is to be stored for 30 days.
Alkylate gasoline
CAUTIONS – Alkylate fuels have different density than
normal fuel. Therefore engines, set with normal fuel,
need different H jet regulation to avoid critical issues.
For this operation it’s necessary turned at a Licensed
Service Dealer.

distance from the cutting area (Fig. 30).
• Always cut with both feet on solid ground to prevent being
pulled off balance.
• Do not cut above chest height.
• Do not cut near electrical wires or buildings. Leave this operation
for professionals.
• Cut only when visibility and light are adequate for you to see
clearly.
• Do not cut from a ladder, this is extremely dangerous. Leave this
operation for professionals.
• Stop the engine if the blade strikes a foreign object. Inspect the
blade and repair parts as necessary.
• Keep the blade out of dirt and sand. Even a small amount of dirt will
quickly dull a blade.
• Stop the engine before setting the hedge trimmer down.
• Be particularly cautious and alert while wearing hearing
protection because such equipment may restrict your ability to
hear sounds indicating danger (calls, signals, warnings, etc).
• Be extremely cautious when working on slopes or uneven ground.
Starting The Engine
Start-up procedure
1) Slowly push the purge bulb 6 times (A, Fig.31).
2) Pull the choke lever (B, Fig.31) in the CLOSE position [0] (C, Fig.32).
In so doing, it also activates automatically half-throttle.

OPERATION
3) Place the machine on the ground in a stable position. Check that
the blade is free. Holding the machine down (Fig.33), pull the
starter rope until the first kick over of the engine is heard (no more
than 3 pulls). A new unit may require additional pulls.
4) Push the choke lever (B, Fig.31) in OPEN (I) position (D, Fig.32).
5) Pull the starter cord to start the engine. Once the machine is
started, warm up the machine for about few seconds, without
touch the throttle lever. The machine could need more seconds to
warm up with cold weather or at high altitudes. Finally, push the
throttle lever (E, Fig.34) for deactivate the automatic half-throttle.
CAUTION:
- Never wrap the starter cord around your hand.
- When pulling the starter rope, do not use the full
extent of the rope as this can cause the rope to break.
- Do not let starter rope snap back. Hold the starter
handle (F, Fig.34) and let the rope rewind slowly.
WARNING: Once the engine is warmed up do not use the
choke to start up again.
WARNING! - Use the semi-acceleration device only in the
phase of starting the engine to cold.
WARNING: Do not cut material with the choke/fast idle
lever at the FULL CHOKE position. Do not operate your
hedge trimmer with the starting throttle lock engaged.
Cutting with the starting throttle lock engaged does not
permit the operator proper control of the hedge trimmer
speed.
NOTE - STARTING WARM ENGINE:
Follow above starting instructions, but do not use the open
Choke position for start up again. To set fast idle for warm engine
starting, pull choke out completely and push back in to the
original Close Position.
WARNING: Weather conditions and altitude may affect
carburetion. Do not allow bystanders close to the hedge
trimmer while adjusting the carburetor.
WARNING: Never attempt to start the hedge trimmer
when the blade is in a cut or kerf.
Breaking-In the Engine
The engine reaches maximum power after the first 5-8 hours of
activity. During this period of breaking-in do not use the engine at
wide open throttle without load, to avoid excessive functioning stress.
WARNING! - During the breaking-in period do not vary
the carburetion to obtain a presumed power increment;
the engine can be damaged.
NOTE: It is normal for smoke to be emitted from a new engine
during and after first use.

Difficult Starting (or starting a flooded engine)
The engine may be flooded with too much fuel if it has not started
after 10 pulls. Flooded engines can be cleared of excess fuel by
following the warm engine starting procedure listed above. Ensure
the ON/STOP switch is in the ON position. Starting could require
pulling the starter rope handle many times depending on how badly
the unit is flooded. If engine fails to start refer to the
TROUBLESHOOTINGTABLE (page 25).
Engine is Flooded
If you did not move the choke lever to warm start, quickly enough
after the engine began to fire, the combustion chamber is flooded.
- Set the on/off switch to STOP.
- Pry off the spark plug boot (1, Fig. 35).
- Unscrew and dry off the spark plug.
- Open the throttle wide.
- Pull the starter rope several times to clear the combustion chamber.
- Refit the spark plug and connect the spark plug boot, press it down
firmly.
- Set the choke lever to OPEN position – even if engine is cold.
- Now start the engine.
Stopping The Engine
Release the throttle trigger (B, Fig. 36) and let the engine return to
idle.
To stop the engine, push the switch (A). Do not put the hedge trimmer
on the ground when the blade is still moving.
In the event that the switch will not function, pull the choke lever in
CLOSE position (refer to Fig. 32) to stop the engine.
Pre-operation checking
WARNING: THE HEDGE TRIMMER SHOULD NEVER MOVE
AT IDLE. Turn the idle speed screw“T” counterclockwise
to reduce the idle RPM and stop the blade, or contact a
Servicing Dealer for adjustment and discontinue use
until the repair is made.
Serious personal injury may result from the blade
moving at idle.

General Working Instructions
WARNING: Do not cut during periods of high wind or
heavy precipitation.
WARNING: Never cut, when visibility is poor or in very
high or low temperatures or in freezing weather.
WARNING - Always wear the harness. Be careful not to
touch the gearbox housing after operation; THESE ARE
HOT ENOUGH TO CAUSE BURNS.
WARNING: Long-term exposure to noise can result in
permanenthearingimpairment.Soalwaysuse approved
hearing protection.
WARNING: Faulty blades can increase the risk of
accidents.
WARNING - If correctly used, the hedge trimmer is a
quick, easy to handle and efficient tool; if used
improperly or without the due precautions it could
become a dangerous tool. THE MACHINE CAN CAUSE
SERIOUS INJURY. For pleasant and safe work, always
strictly comply with the safety rules that follow and
throughout this manual.
• Check the cutting attachment. Never use blades that are dull,
cracked or damaged.
• Check that the machine is in perfect working order. Check that all
nuts and screws are tight.
WARNING: The complete clutch cover and gear housing
must be fitted before the machine is started, otherwise
the clutch may come loose and cause personal injury.
WARNING: If you encounter a situation where you are
uncertain how to proceed you should ask an expert.
Contact your dealer or your service workshop.
Avoid all usage which you consider to be beyond your
capability.
• When the engine is switched off, keep your hands and feet away
from the cutting attachment until it has stopped completely.
• Watch out for stumps of branches that can be thrown out during
cutting.
• Do not cut too close to the ground. Stones and other objects can be
thrown out.
• Check the working area for foreign objects such as electricity
cables, insects and animals, etc, or other objects that could damage
the cutting attachment, such as metal items.
• If any foreign object is hit or if high vibrations occur stop the
machine immediately. Disconnect the HT lead from the spark plug.
Check that the machine is not damaged. Repair any damage.

OPERATION
• If anything jams in the blades while you are working, switch off the
engine and wait until it has stopped completely before cleaning
the blades. Disconnect the HT lead from the spark plug.
• Always wear heavy-duty gloves when repairing the cutting
attachment (Fig.33). This is extremely sharp and can easily cause cuts.
• Release the throttle trigger as soon as the cut is completed,
allowing the engine to idle. If you run the hedge trimmer at full
throttle without a cutting load, unnecessary wear or damage
can occur to the blade and engine.
• If the cutter blades become jammed by thick branches or any other
obstruction, switch off the engine immediately before attempting
to free the blades.
Note: The hedgetrimmer can also be used without the handgrip.
In this case, remove the handgrip and hold the front sheath area
(C, Fig. 34) with your left hand during operation.
CAUTION! - Always set the machine on the ground with
the engine switched off and as shown in Fig. 35.
Cutting season
Observe all country-specific and local regulations and ordinances
regarding hedge trimming.
Preparations
Before starting work, scare away small animals so that they cannot be
injured.
Adjusting the hedgetrimmer (Fig.36)
The angle between the hedgetrimmer and the shaft arm is adjustable
through 12 positions from 0° (fully extended) to 90° (right angle) both
up and down (full range of movement 180°) (Fig.37).
Adjustment procedure:
1. Switch o the engine.
2. Pull the angle adjustment handgrip (A, Fig.38) and twist
anticlockwise to disengage the mechanism.
3. Rotate the attachment to the position desired, selecting the
appropriate hole in the disc.
4. Release the handgrip and ensure the catch pin engages the hole
(Fig.39).
WARNING – With the pin engaged (having made the
adjustment) the handgrip should come to rest on the
housing as before (Fig.40).

Cutting techniques
WARNING! - Do not start the hedge trimmer without the
blade-guard (B, Fig.41). Do not use damaged or
excessively worn blades. If the blade gets jammed, turn
off engine before removing the obstruction.
Trim sides of a hedge fi rst, and then the top. Cut slowly, specially
with thick hedges. If the hedge needs trimming back hard,
proceed gradually, making a succession of shallow cuts rather than
attempting a single deep cut.
Vertical cut: Use an arcing cut from the bottom upwards, then
downwards, to use both sides of the blades (Fig. 42).
Horizontal cut: In order to get the best cutting results, slightly tilt the
blade (5÷10°) towards the cutting direction (Fig. 43).
Overhead cut: using the attachment hedgetrimmer (Fig.44), elevate
the blade to the required height and cut as appropriate, sweeping left
and right in a wide arc.
Transportation
When you walk with your hedge trimmer, turn off the engine and put
on the blade cover (A, Fig.45). Grip the front handle and keep the
cutter blades behind you (Fig.45).
