Safety rules
DANGER
it is necessary to follow certain safety and maintenance rules when doing repair work on vehicles.
here are some of the most important:
SAFETY
- if it is necessary to carry out work on the engine while it is still running, make sure that the premises have adequate ventilation and, if
necessary, use smoke extractors. never leave the engine running in closed premises. Exhaust gases contain co (carbon monoxide), which
can cause loss of consciousness and
death by inhalation
.
- The electrolyte in batteries contains sulphuric acid. Protect your eyes, clothes and skin. Sulphuric acid is highly corrosive; if it comes
into contact with your eyes or skin, flush the area with plenty of water and seek medical advice immediately. if you have accidentally
swallowed electrolyte, drink large amounts of water or milk and seek medical advice immediately.
- Batteries produce hydrogen, a gas that can be highly explosive. do not smoke and ensure that no flames or sparks come near the battery,
especially during recharging operations.
- Petrol is extremely flammable and can be explosive under certain conditions. do not smoke in the work area and make sure that no naked
flames or sparks are produced.
- avoid prolonged contact of used engine oil on your skin; use gloves or wash your hands immediately after use to remove any oil.
- carry out the cleaning of the brake pads in a ventilated location; do noT USE compressed air to clean the pads or brake caliper. although
the powder does not contain asbestos, its inhalation can cause respiratory diseases.
- Brake fluid is extremely aggressive; avoid contact with painted surfaces. Protect painted elements with a clean cloth when performing
operations with brake fluid. Use gloves if possible, as contact of brake fluid with the skin is not recommended.
- Make sure that coolant does not spill onto hot parts, as this produces an invisible flame that cannot be seen and can cause burning.
- do not remove the radiator cap when the engine is still hot, as the coolant is under pressure and at high temperature, which can cause
severe burns.
- if coolant comes into contact with your eyes, flush them immediately with fresh water and seek medical advice.
- during normal operation, the exhaust system and engine are at high temperature. if you have to perform operations on them, wait until
they have cooled down or use suitable gloves to avoid burns.
- avoid wearing loose clothing that could get caught on parts of the vehicle or surroundings. although total safety is impossible, the use of
adequate equipment reduces the possibility and/or severity of injuries.
- always use original gg spare parts and lubricants recommended by the manufacturer. non-original spare parts can damage the engine.
- only use tools specifically designed for this vehicle.
- always replace gaskets, seals and o-rings during servicing and assembly.
- after disassembly, clean the components with non-flammable solvents.
- lubricate all work surfaces prior to assembly, excluding conical couplings.
- apply oil to all pairs of parts and bearings during assembly.
- only use tools with metric measurements during disassembling, servicing and assembling operations. Metric screws, nuts and bolts are
not interchangeable with connecting elements with imperial measurements.
- all surfaces that receive gaskets, seals and o-rings must be cleaned with special care.
- carefully examine all retaining rings prior to assembly and replace any deformed ones. always replace piston pin retaining rings after each
use.
- after assembly, check that all components have been properly fitted and that all mechanisms work correctly.
