Working instructions
Work carefully.
When working with the blower, always
wear it on your back using the carrying
harness. Wrap your fingers tightly
around the handle, keeping the control
handle cradled between your thumb and
forefinger. Keep your hand in this
position to have your machine under
control at all times.
Make sure your control handle (and grip
for vacuum attachment) are in good
condition and free of moisture, pitch, oil
or grease.
Operate the blower under good visibility
and daylight conditions only.
!
Warning!
Your blower produces
poisonous exhaust fumes
as soon as the combus-
tible engine is running.
These gases (e.g. carbon
monoxide) may be color-
less and odorless. To reduce the risk of
serious or fatal injury from breathing
toxic fumes, never start or run the blower
indoors or in poorly ventilated locations.
Ensure proper ventilation when working
in trenches or other confined areas.
Keep the space behind and beside the
engine clear at all times to allow for the
escape of hot and toxic exhaust fumes.

Warning!
To reduce the risk of personal injury, do
not direct air blast towards bystanders,
since the high pressure of the air flow
could injure eyes and could blow small
objects at great speed.
!
Warning!
Always shut off the engine before
cleaning or servicing the unit or
replacing parts.

Warning!
The blower fan between the air intake
and output openings rotates whenever
the engine is running.
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 serious injury
to the operator or bystanders as a result
of the object or broken parts being
thrown out at high speed.
Do not place the blower on the ground
when operating at high speed, because
small objects such as sand, grass, dust,
etc. may be pulled into the air intake and
damage the fan wheel.
To reduce the risk of stumbling and loss
of control,do not walk backward while
operating the machine.
In an emergency, you may slip out of the
harness and throw off the machine
quickly. Try slipping out of the harness a
number of times before using the
machine in order to become
accustomed with it.
Do not throw off the machine while
practising as it could damage the
machine.
Pay attention to the direction of the wind,
i.e., do not work against the wind.
