Fuel Filter; Spark Plug; Storage And Transportation - Truper SOT-145G Instructivo

Fuel Filter

• The fuel filter stops water or dust present in the fuel
tank from entering into the carburetor. If the motor has
not been started after a long period of time, the
sediment container has to be cleaned:
• The motor shall be off and in ambient temperature.
Close the fuel key (E).
• Remove the sediment container (F). Clean the insides
altogether with the filter (G).
• Allow the filter and container to dry completely.
• Verify the washer (H) is in good condition. Set the
sediment container and the fuel filter back into place.
• The external fuel filter shall be replaced according to
the maintenance program indicated in page 13.
Fuel Drain
• Set a container adequate to hold fuel underneath the
tank. Use a funnel to prevent fuel spillage.
• Close the fuel key. Remove and clean the fuel filter as
indicated above.
• Before setting the filter, open the fuel key to drain all
the fuel tank contents. Once drained set back the filter
and sediment container.
• Underneath the carburetor set a container adequate to
hold gasoline. Use a funnel to prevent fuel spillage.
• Remove the drain bolt (A).
• Once fuel is drained into the container set back the
drain bolt and its washer. Tighten firmly.
• Wipe clean any fuel spilled.

Maintenance

Spark Plug

• Before removing the spark plug (B) clean the area
around the spark plug base to prevent dust and debris
entering the motor. Then, remove the spark plug with a
spark plug wrench included with the machine.
• Clean carbon deposits from the spark plug electrodes.
Use a spark plug brush or a wire brush.
• Replace the old spark plug with a similar one if damaged,
worn, or if reusing it is dubious.
• Measure the gap existing between the electrodes. Use a
spark plug gauge. The distance between the central
electrode and the side electrode shall measure 0.03"
• Double check the spark plug washer is in good
condition. Insert back the spark plug manually to prevent
maladjustment.
• After the spark plug is installed adjust with a spark plug
wrench to compress the washer.
• If installing a new spark plug, tighten
CAUTION
up to half a turn after the spark plug is in place and can
press the washer. If installing a used spark plug, tighten
up to a 1/8 – 1/4 turn after the spark plug is in place and
can compress the washer.
WARNING • Maladjusted or out of range spark
plugs can overheat and damage the motor.

Storage and Transportation

• When transporting the machine, turn off the motor
switch and close the fuel key. Keep the machine leveled
to prevent fuel spillage.
• When storing the machine long periods of time:
• The machine fuel shall be drained completely as
indicated in the previous paragraph. Then, start the
motor until all the fuel inside the motor is consumed.
• Replace oil as indicated in page 13.
• Remove the spark plug and pour one spoonful of
SAE-10W/30 oil in the cylinder. Pull the starter lever to
distribute the oil in the system. Then, set the spark plug
back.
• Pull the starter lever slowly until feeling resistance. This
indicates the cylinder is reaching its compression phase
and the exhaust and absorption valves are closed.
Storing the machine in these conditions prevents internal
corrosion.
• Wipe clean the machine with a damp cloth and cover it
to prevent dust entering and accumulating on the
welder.
• Store the machine in a clean, dry place away from
children's reach.
