5.3.3 Clean or replace the air filter
Risk of fire or explosion: for a foam element, only use soapy water and clean engine oil during this operation.
IMPORTANT
If the filter elements are excessively dirty or damaged (torn, pierced), it is essential to replace them with new elements and at least
every 3 cleaning procedures.
1.
Remove the nut (D1) and cover from the air filter (D2).
2.
Remove the wing nut (D3) and filter elements (D4 & D5) to clean them.
3.
Clean the foam element: wash it in soapy water, carefully rinse it and leave it to dry completely.
Soak the foam element in a little clean engine oil and squeeze it gently to remove any excess oil (do not wring it out).
4.
If there is too much oil remaining in the foam, the unit will emit smoke when it is first started.
5.
Replace the paper element.
6.
Check that the rubber seal (D6) is in good condition; replace it if necessary.
7.
Refit the filter elements, wing nut, then the air filter cover and its nut.
5.3.4 Replace the spark plug.
1.
Disconnect the spark plug cap (F1).
2.
Use a dry air spray to clean the spark plug wells.
3.
Use a spark plug spanner to unscrew the spark plug (A15-F2) and discard it.
4.
Fit a new spark plug in position and tighten it by hand to avoid damaging the threads.
5.
Use a spark plug spanner to tighten the spark plug by 1/2 turn after it is seated to compress the washer.
5.3.5 Cleaning the spark arrester
1.
On the exhaust silencer, unscrew the spark arrester mounting bolt (E2).
2.
Remove the spark arrester (E1).
3.
Using a wire brush, remove the carbon deposits from the spark arrester screen.
4.
Check that the spark arrester is in good condition (no holes or cracks), and replace it if necessary.
5.
Refit the spark arrester on the exhaust silencer protection (E3) and retighten the spark arrester mounting bolt.
5.3.6 Cleaning the welding set
To ensure it continues to run correctly, the unit must be cleaned regularly. If the unit is installed inside, always check that the
installation is clean and in good condition. If the unit is being used outside (building sites, dusty, muddy or densely wooded areas,
corrosive environment, etc.), it must be cleaned more frequently.
Use of water sprays or high pressure cleaning equipment is prohibited as this may seriously damage the unit.
1.
Use a brush to gently clean the engine air intakes and outlets and, if present, the spark arrester.
2.
Clean the unit with a sponge and water mixed with a mild detergent (car shampoo, for example), then rinse with fresh
water to remove all traces of the cleaning product.
A cleaning foam may be used and wiped off using a soft, absorbent cloth. Stubborn stains may be removed using a suitable solvent (white
spirit or equivalent) and wiped off using a soft, absorbent cloth.
3.
Check the general condition of the unit (no leakage, tightness of nuts and bolts, connections and hoses, etc.)
4.
Apply an anti-rust product to damaged areas, change defective parts and damaged labels if necessary.
Only use original parts and consult an agent if necessary.
6 Transporting and storing the welding set
6.1
Transport and handling conditions
The unit should be handled gently and brusque movements should be avoided. Ensure that the place where it is to be stored or
used is carefully prepared beforehand. Before transporting the unit, check that the bolts are correctly tightened, close the fuel tap (if
fitted) and disconnect the starter battery (if fitted). The unit should be transported in its normal operating position; never lay it on its
side. Ensure that the unit cannot fall from the vehicle carrying it, but without exerting too much constraint (risk of damaging the unit).
Before any fixed installation on a trailer, consult one of our agents.
6.2
Storage conditions
This procedure for storing the unit or protecting it over the winter must be respected if it is not used for a period of up to 1 year. For
longer periods of storage, it is recommended to contact your nearest agent or to start up the unit for a few hours every year,
ensuring that the storage procedure is respected afterwards.
Drain the fuel and change the engine oil:
1.
Start the unit and allow it to operate until it runs out of fuel.
2.
Set the switch to OFF (A6).
3.
Clean the sediment bowl (A14-C2).
4.
Close the fuel tap (A4).
5.
Top up the oil.
Grease the cylinder and valves:
6.
Remove the spark plug (A15-F2) then, via its aperture, pour in approx. one teaspoon of new engine oil.
7.
Refit a new spark plug in its place.
8.
Pull the starter-recoil reel handle (A7) several times to distribute the oil inside the cylinder.
Storing the unit:
9.
Clean the unit and cover it with a protective cover.
10. Store it in its normal position, in a clean, dry and well ventilated area.
