SAFETY INSTRUCTIONS
Basic working techniques
• Adjust the harness so tlnat the machine is easy to carl T.
I
• The speed of the air jet is controlled with the throttle. Select the speed that best suits the application. To avoid holding your finger on the throttle all the time when using the blower, the required throttle can be set with the throttle adjuster
(D). Full throttle is obtained when the throttle adjuster is pushed in fully.
• Make sure that the air intake is not blocked by leaves or rubbish. This will reduce the machine's air blowing capacity and increase the engine's working temperature, which can lead to engine failure. Stop the engine and remove the object.
• Observe the direction of the wind. Work in the direction o[' the wind to simplify your work.
• Using the blower to move large heaps is time consuming and crcates unnecessary noise.

FUEL HANDLING
Fuel mixture
NOTE!
The machine is fitted with a two-strok_ engine and must ahvays be run on a mixture of petrol and two stroke oil. It is important to measure the quantity ofoil accurately, to ensure the correct mixrure ratio, Small discrepancies in the amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel.
Mixture
• Always mix petrol and eli in a clean container intended for petrol.
• Ahvays start by filling half the quantity of petrol required.
Then add the entire oil quantity. Mix (shake) the fuel mixture. Fil! the remaining quantity of petrol.
• Mix (shake) the fuel mixture carefully before filling in tile machine's fuel tank.
• Do not mix more than max. one month's supply of fuel.
• If the lnachine is trot used for a long period o17time, the fuel tank should be emptied and cleaned.
I _
Petrol
Always provide good ventilation when handling fuel.
NOTE!
Always use an oil-mixed quality petrol (at least 90 octane). If your machine is equipped with a catalytic converteJ; (Jee "technical
data") an unleaded, oil mixed quality petrol should always be used. A leaded petrol will destroy the catalytic converter
• The lowest recommended octane rating is 90. If you run the engine on a petrol with a lower octane rating than 90 so-called
"knocking" can occur.
This leads to an increased engi ne temperature, which can result in a serious engine breakdown.
6
• When working at continuous higln revs a higher octane raring is recommended.
Two-stroke oil
• For the best results use two-stroke oil, which has been specially produced i_r clearing saws and chain saws,
Mixing ratio 1:50 (2%). ISO-L-EGD (180/(20 13738)
• Never use two-stroke oil intended for water cooled outboard motors, so-called outboard motor eli.
• Never use oil intended of four-stroke engines,
_
during and after use.This also applies during idling. Be aware of the fire hazard,
especially when handling the saw near flammable substances or vapours.
Fuelling
WARNINGt
The following precautions reduce the risk
of fire:
Do not smoke or place any sources of heat in the vicinity of the fuel. Never refuel when the engine is running.
Always stop
the engine and let it cool for a few minutes
before refuelling.
Open the fuel cap slowly when fuelling so that any over pressure is released slowly. Tighten the fuel cap carefully after refuelling.
Always move the machine
from
the fuelling place before starting.
• Clean around the fiwl cap. Contamination in the tank can disrupt operations.
• Ensure that the fuel is well mixed by shaking the container before tilting the tank.

MAINTENANCE
Carburettor
Your product has been designed and manuihctured to specifications that reduce harmful emissions.
After your unit has been run 8-10 tanks of fuel the engine has broken in.
'lib ensure that your unit is at peak performance and producing the least amount of harmful emissions after break in, have your authorized servicing
dealer,
who has a revolution counter at his disposal, to adjust your carburettor for optimum operating conditions.
Basic setting
• The carbureetor is set to its basic setting when test run at the l]_ctoU. The basic setting is richer than the optimal setting and should be kept during the machine's first working hours. Thereafter the earburertor should be finely adjusted.
Fine adjustment should be carried out by a skilled technician.
//_
The machine must only be started
as a
WARNINGt complete unit. If the machine is started without all the covers fitted there is a risk of personal injury.
Fine
adjustment
• When the machine has been "run-in" the carburettor should be finely adjusted. The fine adjustment should be carried out by qualified person.
First adjust the L-jet, then the idling screw "l' and then the H-jet.
Conditions
• Before any adjustmems are made the ah:filter should be clean and the airfilter cover fitted. Adjusting the earburettor while a dirty airfilter is in use will result in a leaner mixture when the filter is finally cleaned. This can give rise to serious engine daurage.
Operation
• The carburettor governs the engine's speed via the throttle. Air/fuel is mixed in the carburettor.
The air/{uel mixture is adjustable. To take advantage o_'the engine's optimal output the adjustment must be correct.
•
The setting of the e_trburertor means that the engine is adapted to local conditions, for example, the climate, altitude, petrol and the type of 2-st_:oke oil.

MAINTENANCE
Muffler
NOTE!
Some lnuJ:flers are l:]tted with a catalytic converter. See
"TaWndca!data"to see whether your machine is fitted with a catalytic converten
'lhe muffler is designed to dampen the noise level and to direct the exhaust filmes away from the user. The exhaust fumes are hot and can contain sparks, which can result in fire if the exhaust fimles are directed towards a dr), and inflammable material. Some mufflers are equipped with a special spark arrest screen. I[ your machine is fitted with this wpe of screen it should be cleaned regnlarl> This is done using a wire brush. On mufflers without a catalytic converter _he screen should be cleaned weekly; or replaced if necessar> On mufflers fitted with a catalytic converter the screen should be checked and cleaned monthly. If the screen is damaged it should be l, placed. If the screen is frequently blocked, this can be a sign that the function of the catalytic converter is impaired. Contact your dealer to inspect, the muffler.
A blocked screen will cause the engine to overheat resulting in damagc to the cylinder and piston. Also see under _l,]iah*,'_.,zla:xv'[
NOTE!
Never use a machine with a defective muffler.
Cooling system
To maintain as low operating temperature as possible the engine is equipped with a cooling system.
The cooling system consists off
1.An air intake on the starter unit.
Z Cooling fins on the flywheel.
3. Cooling fins on the cylinder
4. Cylinder cover (leads cold air onto the cylinder).
Clean the cooling system using a brush at least once a week, in difficult conditions more often.
A dirty or blocked cooling system leads to the engine
overheating
resulting in
damage
to the cylinder and piston.
Spark plug
The condition of the spark plug is affected by:
• An incorrect carbnrettor setting.
• An incorrect fuel mixture (too much or
f:aulty oi!).
• A dirty air tiher.
0,5 mm
deposits on the spark plug electrode that may result in malfunction or starting diilicuhies,
If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first.
][ the spark plug is dirty, clean it and at the same time check that the electrode gap is 0,5 ram. Tile spark plug should be changed after about one month of operation or earlier if necessary.
NOTE! Always use the recommended type of spark plug, An incorrect spark plug can damage the cylinder/piston.
