Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Information On Hazards
- Aluminum
Hazards/effects Measures/regulations Repair stage 1 and 2:
No hazards/effectsnone Repair stage 3: (Welding - only E52) - Explosion hazard due to high concentration of fine aluminum dust.
Arising e.g. during straight-through grinding of coated components in the base material and large-surface grinding of bright-finish components.
- Explosion hazard due to swirling up of fine aluminum dust in cavities.
Created by the necessary, thorough cleaning of machining surfaces and tools before and after machining aluminum.
- Avoid high concentration of fine aluminum dust by means of continuous extraction.
- Use explosion-proof exhaust extraction unit
- Do not use compressed air when cleaning the workbay.
- Avoid swirling up dust when cleaning the workbay.
- Spontaneous combustion of fine aluminum dust when ignition and fire sources are drawn in.
E.g.: hot shavings, grinding sparks, cigarettes, etc.- Do not operate ignition and fire sources in the intake area of exhaust extraction unit.
- Explosion hazard due to high concentration of fine aluminum dust.
- Carbon Fiber Reinforced Plastic
Hazards/effects Measures/regulations Repair stage 1:
No hazards/effectsnone Repair stage 2 and 3: - Explosion hazard due to high concentration of Carbon Fiber Reinforced Plastic dust.
Produced when grinding Carbon Fiber Reinforced Plastic.
- Explosion hazard due to build up of Carbon Fiber Reinforced Plastic dust in cavities.
Created by the necessary, thorough cleaning of machining surfaces and tools before and after machining Carbon Fiber Reinforced Plastic.
- Avoid high concentration of Carbon Fiber Reinforced Plastic dust by suctioning it off continuously.
- Use explosion-proof exhaust extraction unit
- Do not use compressed air when cleaning the workbay.
- Avoid swirling up dust when cleaning the workbay.
- Spontaneous combustion of Carbon Fiber Reinforced Plastic dust when ignition and fire sources are drawn in.
E.g.: hot shavings, grinding sparks, cigarettes, etc.- Do not operate ignition and fire sources in the intake area of exhaust extraction unit.
- Explosion hazard due to high concentration of Carbon Fiber Reinforced Plastic dust.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
