1. SAFETY WARNING:
For your safety and safety of others please pay special attention to these
precautions:
1) Training
a) Read the instructions carefully. Be familiar with the controls and the
proper use of the equipment;
b) Never allow children or people unfamiliar with these instructions to use
the machine. Local regulations can restrict the age of the operator;
c) Never work while people, especially children, or pets are nearby;
d) Keep in mind that the operator or user is responsible for accidents or
hazards occurring to other people or their property.
2) Preparation
a) While working, always wear substantial footwear and long trousers. Do
not operate the equipment when barefoot or wearing open sandals;
b) Thoroughly inspect the area where the equipment is to be used and
remove all objects which can be thrown up by the machine;
c) WARNING – Petrol is highly flammable:
 Store fuel in containers specifically designed for this purpose;
 Refuel outdoors only and do not smoke while refuelling;
 Add fuel before starting the engine. Never remove the cap of the
fuel tank or add petrol while the engine is running or when the
engine is hot;
 If petrol is spilled, do not attempt to start the engine but move the
machine away from the area of spillage and avoid creating any
source of ignition until petrol vapours have dissipated;
 Replace all fuel tank and container caps securely;
d) Replace faulty silencers;
e) Before using, always visually inspect to see that the tools are not worn
out or damaged. Replace worn out or damaged elements and bolts in sets
to preserve balance.

monoxide fumes can collect;

b) Work only in daylight or in good artificial light;
c) Always be sure of your footing on slopes;
d) Walk, never run with the machine;
e) For wheeled rotary machines, work across the slopes, never up and
down;
f) Exercise extreme caution when changing direction on slopes;
g) Do not work on excessively steep slopes;
h) Use extreme caution when reversing or pulling the machine towards you;
i) Do not change the engine governor settings or overspeed the engine;
j) Start the engine carefully according to manufacturer instructions and with
feet well away from the tool(s);

working condition;
b) Never store the equipment with petrol in the tank inside a building where
fumes can reach an open flame or spark;
c) Allow the engine to cool before storing in any enclosure;
d) To reduce the fire hazard, keep the engine, silencer, battery
compartment and petrol storage area free of vegetative material and
excessive grease;
e) Replace worn or damaged parts for safety;
f) If the fuel tank has to be drained, this shall be done outdoors.
Thrown Object Hazard
Objects hit by the rotating tines can be thrown from the tiller with great force
and may cause severe injury.
1) Before tilling, clear the tilling area of sticks, large stones, wire, glass

etc.
2) Pieces thrown from worn or damaged-tines can cause serious injury.
Always inspect the tines before using the tiller.
Fire and Burn Hazard
Gasoline is extremely flammable and gasoline vapor can explode.
Use extreme care when handing gasoline. Keep gasoline out of reach of
children.
1) Refuel in a well-ventilated area with the engine stopped.
2) Allow the engine to cool before refueling. Fuel vapor or spilled fuel
may be ignited.
3) The engine and exhaust system becomes very hot during
operation and remains hot after stopping. Touching them can cause burn
injuries or some materials burn.
4) Avoid touching a hot engine or exhaust system.
5) Allow the engine to cool before performing maintenance or storing
the tiller indoors.
Carbon Monoxide Poisoning Hazard
Exhaust contains poisonous carbon monoxide a colorless and odorless gas.
Breathing exhaust can cause loss of consciousness and may lead to death.
Operation on Slope
1) When tilling on slopes, keep the fuel tank with less than half oil to
minimize fuel spillage.
2) When the tiller walks across the slope, put your effort evenly while
walking up and down the slope.
3) Be very careful when changing the direction of the tiller on a slope.
4) Do not use the tiller on a slope of more than 10°.
5) The maximum safe grade angle shown is for reference only and
the details should depend on the type of the tool. Before starting the engine,
check that the tiller is not damaged and in good condition. For your safety
or safety of others, pay special attention when using the tiller up or down hill.

8. MAINTENANCE
Please note that maintenance operations are scheduled for normal
operating conditions. If the operation of tiller takes place under other
conditions, we recommend that you communicate with your dealer to
deal with the machine.
1. Turn off the engine and disconnect the spark plug prior to
maintenance operations.
2. Allow the engine and exhaust system to cool to avoid burns
from contacting with hot parts.
3. It is important to keep safety gloves in the event that you need
to manipulate the blades.
4. Wipe the dirt things on the machine.
5. Remove the fuel from tiller if this is to be stored for longer than a month.
6. It is appropriate to check that all bolts and nuts have not been loosened
after each session.
7. The guard should be fixed after assembling and it should not be removed
or adjusted during use and maintenance
For the normal maintenance (oil, filter, spark plug) check the booklet for
the engine included.
The chain for the final transmission is lubricated with normal grease.
Every year you should introduce some grease through the hole “Q”
(Pict.14) in the main body.
Keep the machine and the tillers clean and check that all the screws
and nuts are well tied, especially the screws of the tiller (always wear
protection gloves working on the tiller).
In case of breaking or wearing you can replace the belt after taking off

the side protection cover fixed to the frame near the engine shaft by two
screws.
Remove the belt from the pulleys, install the new belt end adjust it
following the instructions mentioned in the chapter USE AND
ADJUSTMENT by checking the distance between both sides of the belt,
then replace the cover.
The pin fixing the big pulley has also a safety purpose: in case heavy
obstacle it will break avoiding damages to other parts of the machine.
The replacement of the pin is very easy: you have to insert the new pin
in the hole using a hammer.
For any technical repair especially during the guarantee period, it is
recommendable to apply to the specialized workshops of our dealers.
CAUTION:
It is advised not to keep the motor running when the machine is not being
used for its specific purpose.
