Before starting work, switch on exhaust
extraction system and place an extraction hose
close to the sensor opening in fuel tank to
extract escaping fuel fumes. If no exhaust
extraction system is available, a radial fan (as
long as motor is not in air flow) with a
displacement greater than 15 m
used.
Prevent gasoline from contacting skin! Wear
fuel-resistant gloves!
For safety reasons, fuse no. 18 must be removed
from fuse holder before opening fuel supply
system.
