General Safety Rules
SAVE THESE INSTRUCTIONS
WARNING! Read all instructions Failure to follow all
instructions listed below may result in electric shock, fire
and/or serious injury. The term “power tool” in all of the
warnings listed below refers to your mains-operated
(corded) power tool or battery-operated (cordless) power
tool.
1) Work area
a) Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce
risk of electric shock
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of
electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
b) Use safety equipment. Always wear eye
protection.Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
c) Avoid accidental starting. Ensure the switch is in
the off-position before plugging in.Carrying
power tools with your finger on the switch or
plugging in power tools that have the switch on
invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
f ) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
awayfrom moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
c) Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tools operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
f ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits
etc., in accordance with these instructions and in
the manner intended for the particular type of
power tool, taking into account the working
conditions and the work to be performed. Use of
the power tool for operations different from intended
could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power tool
is maintained.

Immediately throw away old cables or plugs when they have
been replaced by new ones. It is dangerous to insert the
plug of a loose cable in the wall outlet.
Only use an approved extension cable suitable for the
power input of the machine. The minimum conductor size is
1.5 mm2. When using a cable reel always unwind the reel
completely Inadequate extension cords can be dangerous. If
an extension cord is used, it shall be suitable for outdoor
use, and the connection has to be kept dry and off the
ground. It is recommended that this is accomplished by
means of a cord reel which keeps the socket at least 60 mm
above the ground.
This appliance operates at a temperature of 600 degrees
without visible signs of this temperature (no flames), still
there is a chance of fire risk. Watch out for the hot air stream

CAUTION!
To avoid overheating of the BBQ or Fireplace do not use the
device for longer than necessary.
With the temperature adjustment lever (1) you can select from
three temperature settings depending on application.
The nozzles can easily be pushed over the hot air nozzle (3).
Never touch the nozzles during operation or right after use
of the device. The nozzles are very hot.
The device has two handle positions. Position 1-a is suitable
for killing weeds and Position 1-b is for lighting charcoal. In

7. Press the On/Off switch.
8. Allow the device about 45 seconds to warm up.
9. To eliminate weeds, hold the nozzle over the weeds for
about 5 seconds.
During these 5 seconds the cell structure of the weed is
destroyed. As a result, the weed dies within a few days.
It is not necessary to completely burn the weeds, 5 seconds
is more than sufficient.
For an efficient treatment the nozzle should be held
around 0 to 5cm above the weeds.
The effects are not visible immediately but will take a while
before they can be seen. It is more of a long-term effect.
