General information and Maintenance

Safety prescriptions

- If the work to be carried out requires the vehicle
engine to be running, make sure the workshop is
well ventilated and use proper exhausters. Do not
run the engine in closed places. Exhaust fumes are
toxic.
- Battery electrolyte contains sulphuric acid. Protect
the eyes, clothes and skin. Sulphuric acid is highly
corrosive, if it comes into contact with eyes or skin,
wash the affected area abundantly with water and
seek immediate medical assistance.
- The battery produces hydrogen gas which is poten-
tially explosive. Do not smoke near the battery and
keep naked flames and sparks well clear, especially
when the battery is on charge.
- Petrol is highly flammable and can be explosive in
certain conditions. Do not smoke in the work area
and do not introduce naked flames or sparks.
- Clean brake shoes, drums and pads in a well
ventilated place. When using compressed air direct
the jet away from you to avoid inhaling the dust.
Although the brake linings are asbetos-free, inhala-
tion of the resulting dust is harmful.
