6. Maintenance
6.1 When using liquid fuel, the jet must
be cleaned regularly for optimal, problem-
free use. If the appliance is used for a long
period of time, or with inferior fuel, the fuel
connections will need to be cleaned,
6.2 Cleaning the Jet
Close the control knob (2) completely and
unscrew the LP Gas cartridge (3).
6.3 Squeeze the spring-loaded burner holder
(10) and remove the burner.
6.4 Loosen the clamp screw (14) on the
injector tube (12) and remove the preheating
coil (11).
6.5 Unscrew the jet (9) with the multitool or an
8mm open-end wrench.
6.6 Clean the jet using the cleaning wire on the
multitool. 6.7 Mount the jet on the pipe and
make it leak-proof by tightening it carefully. Do
not tighten too hard. Check that it is leak-proof
with soapy water or similar.
6.8 Place the preheating coil in the injector
tube (12), fasten it with the clamp screw (14),
and reattach the burner holder (10).
6.9 Cleaning the fuel connection
A cleaning wire (16) is delivered with the
appliance for this purpose. The wire is stored
in the fuel pipe (11).
6.10 Unscrew the hose from the fuel
connection with the multitool. Pull the
deaning wire out using the multitool. Pull the
wire backwards and forwards until the fuel
connection is clean. Rush the fuel connection
with the jet disassembled, and connect the
fuel pump/bottle to the appliance. Pressurise
the fuel bottle and open the control valve
and flush half a cupful of fuel through the fuel
connection. Warning: This must not be carried
out in the vicinity of a source of ignition such
as open flame, pilot flame or electric heater.
Do not spill fuel. Assemble the hose and screw
it down so that the connection is leak proof.
Do not tighten too much. For extra safety do
this outdoors. Check that there are no leaks
using soapy water or similar. Assemble the
stove in accordance with Item 6.7.
6.11 Fuel pump
If the pump does not pressurise the fuel bottle,
stretch the leather gasket (17) slightly and
oil it with Primus leather oil (saliva or other
mineral-based oil). Unscrew the pump rod and
pull it out. Rub the oil into the leather gasket
until it is soft and pliable. If the pump does not
pressurise the fuel bottle despite this, replace
the leather gasket arid/or check the O-ring on
the back valve (18). Clean if necessary.
