SOLUTIONS
Check the terminal board with a tester
Unlock the motor using a tool
Check and set the electrode to the right
position
Check and connect properly
Open the gas tap
Replace the cylinder
Remove the nozzle and clean it
Find leaks using approved leak detector
and connect properly
Repeat the starting operation keeping the
button pushed for a longer time
See point
"The motor does not work"
Check the pressure reducer and if
required replace it
Check that the motor works properly
Check and eventually use a larger cylinder
or two cylinders connected parallely.
