Failure	Cause	Remedy
The ZON MARK 5, fully connected, fails to operate at all.	The valve of the gas tank is not open.	Open the valve.
	The battery cable has not been connected.	Ensure the battery terminals are connected properly. The black terminal is negative (–) and the red terminal is positive (+).
	Low battery.	Recharge or connect a new battery.
	The gas tank is empty or has too little pressure.	Connect a new gas tank.
	The gas valve will not operate.	Check the connection points. If properly connected, call the dealer for repair.
	The control unit is not turned on.	Turn on switch on control box.
The ZON MARK 5 leaks.	The coupling nut gas regulator is not tight enough.	Tighten coupling nut.
	The hose from the regulator-unit to the ZON MARK 5 has been damaged.	Replace the hose. A fast method to trace a leak in the gas regulator is to check it with a leakage spray.
The ZON MARK 5 operates, but there is no explosion or sound.	The hose fracture protector button (red) has not been pushed.	Push the red button on the hose fracture protector one or more times.
	Ignition gives a weak spark or no spark at all.	Check the electrode (no. 91536) It is possible that the porcelain or the mass point is broken, if so replace. Distance mass point on electrode is not correct. This must be 2.5 – 3.0 mm. If not, adjust with pair of pliers. Electrode (no. 91536) is wet. Dry it well.
	Poor gas mixture.	Replace gas tank.
	Gas valve is blocked or partially blocked.	Open up blockage using thin wire of approximately 0.6 mm diameter (wire from a steel brush).
The ZON MARK 5 works, but gives dull explosions.	Wind is too strong – gas/air mixture is disturbed.	Place the ZON MARK 5 downwind or, if possible, place it out of the wind, or behind a screen.
	Telescopic megaphone is not pulled out or is only partially pulled out.	Pull out to full extension.
For receiver units: Transmission range reduced.	Weak batteries in transmitter.	Replace batteries.
