
The machine case is made mainly from aluminium alloy for lightness, so can be damaged by shocks and
impacts. Therefore, take care not to let heavy objects fall on the machine and do not drop the machine when
moving it.

Have the motor turning when adjusting the speed.

Always keep the rail surface clean to prevent knocking. Pay special attention to places along which the wheels
pass. Also, be careful not to damage the drive wheel or idle wheel.

Take care that the path of the machine is not hindered by the hoses running from the regulator to the distributor
connection.

Always make sure the cutting tip is fastened tightly to the torch. Be careful when handling the cutting tip not to
damage the tapered section.

WARNING
–
Never use the machine outdoors in wet weather. This may cause electric shock and damage the
machine.

Never move the machine when the pre-heat flame is on

When moving the rail, be sure to take down the machine body off the rail.
3.02 TESTING FOR LEAKS BEFORE USE
After assembly and before use, it is recommended that the following procedure be adopted to check for leaks.

Before opening the cylinder valve, turn the Regulator adjusting knob fully anti-clockwise until there is no
pressure on the internal adjusting spring and the knob turns freely.

Ensure all valves on downstream connected equipment are closed.

Stand to the side of the cylinder opposite the Regulator adjusting knob before opening the cylinder valve. Keep
the cylinder valve between you and the Regulator.

Open the cylinder valve slowly - if opened quickly, a sudden pressure surge may damage internal Regulator
parts. Set the Regulator to show approximately 100 kPa on the delivery gauge, by turning the adjusting control
knob clockwise.

Close the cylinder valve.

Turn the adjusting knob anti-clockwise one turn:
a) If the high pressure (cylinder contents) gauge reading drops, there is a leak in the cylinder valve, inlet fitting,
or high pressure gauge.
b) If the low pressure (delivery) gauge drops, there is a leak in the downstream equipment, hose, hose fitting,
outlet fitting, or low pressure gauge. Check for leaks using a suitable leak detection solution.
c) If the high pressure gauge drops and the low pressure gauge increases at the same time, there is a leak in the
internal Regulator seat.
d) If the Regulator requires service or repair, refer to Section 5.

If there are no leaks found, then the system is ready for use.

Repeat test for the second gas system (where applicable)
