Risks
Sulfuric acid mist is corrosive and injures the respiratory tracts.
(Generated when heating certain plastics and paints.)
Isocyanates can be released in the form of steam, dust (or may be
present in aerosols) when cutting, grinding or welding. Can irritate
mucous membranes producing symptoms similar to asthma and im-
pairing lung function. Even brief exposure to high concentrations
can give problems with persistent high sensitivity.
Safety precautions
• Make sure of adequate ventilation with fresh air when welding,
battery charging and other work when hazardous gases are gen-
erated.
• Use suitable gloves and breathing protection when there’s a risk
of oil mist. Make sure that protective gear is oil-resistant.
• Apply oil-resistant protective lotion to unprotected skin.
• Make sure that an eye-wash station is in the immediate vicinity
when working with corrosive substances.
• Avoid unnecessary operation of the machine inside the work-
shop. Connect an air extractor to the exhaust pipe so that the
exhaust fumes are removed from the workshop.

Tensioned springs
Examples of tensioned springs:
1. Torque springs in pedals for example.
2. Return spring (cup springs) in parking brake cylinder.
3. Lock rings
4. Gas springs
Risks
If a tensioned spring releases, it is shot out by the spring force and
can also take adjoining parts with it.
Small springs can cause eye injuries.
Parking brake springs are tensioned with high force and can cause
very severe accidents if they are accidentally released in an uncon-
trolled manner.
Gas springs and gas-charged shock absorbers are tensioned with
high force and can cause very severe accidents if they are acciden-
tally released in an uncontrolled manner.
Safety precautions
• Use safety glasses.
• Lock rings should be of a suitable type and in good condition.
• Follow the instructions in this and other manual when perform-
ing maintenance and changing parts and components.
• Always use recommended tools.
