Weed Destroyer BG 500

Do not change settings or make modifications made by the
producer. It is dangerous to change the structure of the device on
your own authority, to remove parts or to use parts which are not
approved by the manufacturer.

Use with this device solely gas cartridges of 330 g, which correspond
to the European Norm EN 417 (e.g. cartridge No. 70801, which
is provided, or replacement cartridges No. 48810 + 52107). These
standard gas cartridges can be obtained in building and home
stores easily. It could be dangerous to try to attach other gas

cartridges.

The device may only be used outside.

Steps to be taken before fitting the gas cartridge

Make sure that all attachments and other connections are correctly
connected and nothing is damaged. Before attaching the gas
cartridge ensure the gasket (No. 8, picture II) in the gas supply
valve of the device (No. 6) is not missing and that it is in a good
condition (visual check). This gasket guarantees a gas tight
connection between the device and the cartridge. Ensure that
parts where the gas flows are not damaged. Do not use a device
with a damaged or worn out gasket. Do not use a leaking or
damaged device or a device not working properly. Before fitting
the gas cartridge, close the gas regulation valve on the device.
It is very important that always before you light the flame on the
burner, you make sure that all parts are tightly connected. Never
look for a leaking spot with a flame but use soapsuds (e.g. 10
drops of washing-up liquid with water) or a leak seeking spray.

Very important!

Do not use the device in a way where the gas cartridge is held
horizontally or where the cartridge valve is pointing downwards.
In this case, liquid gas would stream into the burner, which would
lead to a reddish blazing uncontrolled flame. It is possible that the
burner will not work properly. The appliance has to be immediately
positioned upright again (see picture I) with the cartridge valve
pointing up and the gas regulation valve (No. 1) is to be closed.
After 2-3 minutes the appliance is fully functional again. Do not
shake the gas cartridge / device before or during operation as the
liquid gas could stream out. Should the liquid gas stream out,
close the gas regulation valve (No. 1) immediately. After 2-3
minutes the appliance is fully functional again.

Change the gas cartridge only when outside, far away from all
possible combustible sources, as e.g. open fire, pilot lights, electric
cooking appliances, and in a sufficient distance from other persons.

Test for Leaks

If gas leaks out of your device (you can smell gas), take it out
immediately to a place with a good air circulation with no
inflammable sources, where you can look for the leak and fix it.
Be very careful to test gas tightness of your device only outside.
Never seek leaking connections using a flame. Always spread
soapsuds over the connections or use a leak-seeking-spray!

Use of the Weed Destroyer BG 500

Destroying weeds chemically is not up-to-date any more. Moreover,
use of such agents is forbidden in many countries. By purchasing
Weed Destroyer BG 500 you got a device with which you can
biologically kill weeds and destroy moss with success. The weeds
will be heated up but not burnt. Due to the quick rise of the
temperature the cell fluid expands, the cell walls burst, the protein
coagulates and the weeds die. For that purpose it is sufficient that
the plant is heated from the distance of approximately 10 cm from
the burner head. After several days the plant wilts and should be
removed. Certain plants, which are particularly resistant, have to
be re-treated in an interval of 3 weeks. The use of this warming
up method is completely poison-free. That is why no harmful
substances can either get into the food chain or into the water.

The device destroys weeds at the outdoor steps, courtyards,
house entrances/doorways, pavements, terraces, garage gateways,
parking spots, sandpits, house walls, etc. The device is also ideal
to light a grill. In winter the device is also a useful assistant to de­ice and defrost small areas.

We hope the Weed Destroyer BG 500 will be a useful and reliable
helper for many years.

Technical data

Flame temperature: approximately 1.600 °C
Gas type: mixture of propane/butane
Category of the device: Mixture of propane-butane, direct

compression

Nominal heat load/capacity: approximately 200 g/h,

approximately 2,75 kW
Nozzle No.: 32
Nozzle: Ø 0,32 mm

The power rating during the normal operation can vary from the
values set in the instruction for use (e.g. when using longer on
large areas the performance declines. The reason for this is the
icing up of the cartridge due to the withdrawal of gas).

Important information: The ambient temperature has an
essential influence on the performance of the device. As a
general rule is that the performance decreases at low
temperatures.

Technical and optical parameters are subject to change.

Storage and transportation

After end of work, before storage and transport, always unscrew
the gas cartridge from the device.
Ensure that the device has cooled down and the gas supply valve
is closed, before you store it securely and in a dry place. The
same applies for transport. Here you must ensure that the device
is secured and cannot fall over or down. Always transport the
device and the gas cartridge separately. Important: When screwing
off the gas cartridge the gas supply valve of the gas cartridge
closes automatically and no further gas can escape.

Fitting the gas cartridge

The Weed Destroyer is completely assembled apart from the gas
cartridge. Before you attach the gas cartridge (No. 5) to the device

- outside, away from possible combustible sources, as e.g. open
fire, pilot flames, electrical cooking devices, and in a sufficient
distance from other persons - , please ensure that the gas regulation
valve (No. 1) is tightly closed. Before you attach the supplied gas
cartridge onto the weed destroyer, remove the protective cover
on the gas cartridge. To do so, you will need a screwdriver or a
similar tool. Now, holding the gas cartridge vertically, screw it
tightly onto the gas supply valve (No. 6), as shown above (picture
I), so that no gas can stream out. The gasket (No. 8) has to be
checked before each new connection of the gas cartridge (visual
check  see picture II). Test gas tightness by spreading soapsuds
over the parts where the gas streams or spray them with a leak­seeking-spray. Check the gas tightness of your device only outside.
Never seek leaking connections using a flame, always use
soapsuds or a leak-seeking-spray (as described)!

How to operate the device

Close the gas regulation valve (No. 1). Remove the protective
cover on the gas cartridge (No. 5). Afterwards attach the gas
cartridge (No. 5) properly onto the gas supply valve (No. 6). Hold
the Weed Destroyer BG 500 as shown in picture I and screw on
tightly the gas cartridge (No. 5) in direction of the arrow so that
no gas can stream out. Afterwards open the gas regulation valve
(No. 1) slightly and light the flame by pressing several times the
red piezo ignition button (No. 3). For security reasons, it is necessary
to hold the burner head at an angle pointing downwards. The
bottom of the cartridge shows also vertically downwards (see
picture I). If the gas regulation valve (No. 1) is opened too far, too
much gas streams into the burner (No. 4) and the flame can be
lighten badly. Therefore when starting the operation open slightly
the gas regulation valve (No. 1) (appx. ¼ rotation in direction (+)).
Afterwards press several times the red ignition button of the piezo
firing (No. 3), so that the gas automatically lights at the burner
(No. 4). After that the gas regulation valve (No. 1) can be opened
more, so that the flame can reach its full performance (by turning
the regulation valve in direction of (+) the gas supply increases).
When using the device, ensure there is sufficient distance
(approximately 10 cm) to the plant you want to destroy. Do not try
to treat weeds after either rain or dew as the gas consumption
becomes too high and the flame could be affected. The same
applies if there is a strong wind.

Switching off the device

By turning off the gas regulation valve (No. 1  turning the regulation
valve in direction of (-), the flame at the burner will extinguish after
a short delay. This delay occurs as there is still remaining gas in
the extension tube (No. 2) after the gas regulation valve has been
turned off.

Changing the gas cartridge

Ensure the flame has extinguished before you loosen the gas
cartridge.
Afterwards unscrew the gas cartridge from the device. The device
must cool down completely before it is stored or transported.
Check the gasket (No. 8, picture II  visual check) before you
connect a new gas cartridge. Change the gas cartridge outside
and in a sufficient distance from other persons. Before you attach
the gas cartridge (No. 5) to the device - outside, far away from
possible combustible sources, as e.g. open fire, pilot flames,
electrical cooking devices, and in a sufficient distance from other
people - , please ensure that the gas regulation valve (No. 1) is
tightly closed. Now, holding the gas cartridge vertically, screw it
tightly onto the gas supply valve (No. 6), as shown above (picture
I), so that no gas can stream out. The gasket must be checked
before each new connection of the gas cartridge.

Cleaning the device

To clean the device, wait until the burner has cooled down and
use a dry cloth. Do not use any cleansing agents because the
openings in the burner and the nozzles could become blocked.
