Always hand over the instruction manual.
First-time users should ask the dealer for basic instructions to familiarize
oneself with the handling of a blower.

Personal protective equipment
The clothing worn should be functional and appropriate, i. e. it should be

long hair which could be drawn into the air intake.
In order to avoid head-, eye-, hand- or foot injuries as well as to protect
you hearing the following protective equipment and protective clothing
must be used during operation of the blower.
Pay particular attention to the following regulations:
Clothing must be sturdy and snug-tting, but allow complete freedom
of movement. Avoid loose-tting jackets, ared or cuffed pants, scarfs,
unconned long hair or anything that could be drawn into the air intake.
Wear overalls or long pants to protect your legs. Do not wear shorts. (4)
Blower noise may damage your hearing. Wear sound barriers (ear plugs
or ear mufers) to protect your hearing. Continual and regular users
should have their hearing checked regularly. (3)
Use of gloves when working with the blower is recommended.
Good footing is most important. Wear sturdy shoes with nonslip soles.
(4)
Proper eye protection is a must. Even though the discharge is directed
away from the operator, ricochets and bouncebacks can occur during
blower operations. (3)
Never operate a blower unless wearing goggles or properly tted safety
glasses with adequate top and side protection.
Starting up the blower
Please make sure that there are no children or other people within a
working range of 15 meters (5), also pay attention to any animals in the
working vicinity. Never use the blower in urban areas.
Before operating, always check that the blower is safe for
operation:
Check the security of the throttle lever. The throttle lever should be
checked for smooth and easy action. Check for proper functioning of the
throttle lever lock. Check for clean and dry handles and test the function
of the ON/OFF switch. Keep handles free of oil and fuel.

Start the blower only in accordance with the instructions.
Do not use any other methods for starting the engine ! (6)
Use the blower and the tools supplied only for applications specied.
Start the blower engine only after the entire assembly is done.
Operation of the tool is permitted only after all the appropriate ac-
cessories are attached!
The engine is to be stopped immediately if there are any engine
problems.
When working with the blower, always wrap your ngers tightly around
the handle, keeping the control handle cradled between your thumb and
forenger. Keep your hand in this position to have your machine under
control at all times. Make sure your control handle (and grip for vacu-
um attachment) are in good condition and free of moisture, pitch, oil or
grease.
Always ensure a safe, well-balanced footing.
Only use outdoors.
Operate the blower in such a manner as to avoid inhalation of the ex-
haust gases. Never run the engine in enclosed rooms (risk of suffocation
and gas poisoning). Carbon monoxide is an odorless gas. Always ensure
there is adequate ventilation.
Stop the engine when resting and when leaving the blower unattended.
Place it in a safe location to prevent danger to others, setting re to com-
bustible materials, or damage to the machine.
Never lay the hot blower onto dry grass or onto any combustible
materials.
Never operate the engine with a faulty exhaust mufer.
Stop the engine during transport (7).
Position the blower safely during car or truck transportation to avoid fuel
leakage.
When transporting the blower, ensure that the fuel tank is completely
empty.
Refuelling
Stop the engine during refuelling (7), keep well away from open ame (8)
and do not smoke.
Do not attempt to refuel a hot or a running engine.
Avoid skin contact with petroleum products. Do not inhale fuel vapor.
Always wear protective gloves during refuelling. Change and clean pro-
tective clothing at regular intervals.
Take care not to spill either fuel or oil in order to prevent soil contamina-
tion (environmental protection). Clean the blower immediately after fuel
has been spilt. Allow wet cloths to dry before disposing in proper, covered
container to prevent spontaneous combustion.
Avoid any fuel contact with your clothing. Change your clothing immedi-
ately if fuel has been spilled on it (danger hazard).
Inspect the fuel cap at regular intervals making sure that it stays securely
fastened.
Carefully tighten the locking screw of the fuel tank. Change locations to
start the engine (at least 3 meters away from the place of refuelling) (9).
Never refuel in closed rooms. Fuel vapors accumulate at ground level
(risk of explosions).
Only transport and store fuel in approved containers. Make sure stored
fuel is not accessible to children.
When mixing gasoline with two-cycle engine oil, use only gasoline which
contains no ethanol or methanol (types of alcohol). This will help to pre-
vent damage to fuel lines and other engine parts.

Method of operation
Use the blower only in good light and visibility. During cold seasons be-
ware of slippery or wet areas, ice and snow (risk of slipping). Always
ensure a safe footing.
Never work on unstable surfaces or steep terrain.
To reduce the risk of personal injury, do not direct air blast towards by-
standers, since the high pressure of the air ow could injure eyes and
could blow small objects at great speed.
Never insert any foreign object into the air intake of the machine or into
the nozzle of the blower. It will damage the fan wheel and may cause seri-
ous injury to the operator or bystanders as a result of the object or broken
parts being thrown out at high speed.
Pay attention to the direction of the wind, i.e., do not work against the
wind.
To reduce the risk of stumbling and loss of control, do not walk backward
while operating the machine.
Always stop the engine before cleaning or servicing the unit or replacing
parts.

pollution as possible. In particular check the correct adjustment of the
carburetor.
