1. GENERAL NOTES
1.1 WARNING: For models which connect to mains electrical power, before exposing an of the internal
electrical wiring the appliance must be disconnected from electrical power b unplugging the service cord
from the electrical outlet. For models which connect to batter power, before exposing an of the internal
electrical wiring the appliance must be remove the batter also.
1.2 An servicing carried out on gas containing components where seals are broken including manifold,
regulator, valves and burner suppl pipes should be followed b a leak test. Gross leaks can be detected b
connecting a manometer to the regulator test point, pressurising the manifold and then shutting off the gas
with a ball valve. A falling manometer reading indicates a leak. Small leaks can be located with soap and
water applied at the connection.
1.3 Burner suppl pipes leading from the burner control to the burner should have their compression fittings
tightened firml but not over tightened (If a torque spanner is used set this to 10 12Nm). If the tubes are
damaged the should be replaced. The soundness of the connections on the burner suppl tubes can be tested
b blocking the injector orifice temporaril , eg. b fitting an injector that has been blocked and leak testing
the fittings.
1.4 When reassembling the appliance any earth leads whi h have been dis onne ted must be re- onne ted.
1.5 Reassembl procedures are a reversal of removal procedures.
1.6 Replace the spare part with original spare parts. The modif part must not be used.
1.7 All the screws in this appliance have been designed for difference purpose. The must be use in the right
position and must be the right dimension. If there are an differences from the original design the ma have
the serious accident.

2. Low pressure regulator (Safety warning: Do not use high pressure regulator)
3. Flexible rubber hose or copper tube
4. Elbow coupling gas with fibre washer (Warning: Do not use regular rubber washer)
5. 2 steps safet valve
6. Burner
7. Ignition switch

Gas from the tank (1) is released from the low pressure regulator (2) into the hose or tube (3), travelling pass
the elbow coupling to the valve (4). To ignite the burner, press down and turn the safet valve (5) counter-
clockwise simultaneousl . This opens up the valve, letting the gas to the nozzle of the burner (6), and turns the
ignition switch to on (7) at the same time. The electrical current is automaticall supplied from the batter to
spark plug generator (8), and then to the pin heads (9), causing the ignition (10). The burner is ignited and bursts
into flame (11).

5. REPAIR PROCESS
5.1 Remove out the dirt oil from nozzle
1. Clean the head of nozzle with the cloth
2. Use the nozzle cleaner or the needle insert into the hole of nozzle.
3. Do repeat the step 1 and 2 for a few time until the nozzle is clean.
5.2 Removal of Hob & Access to Internal Components
