- Fix the suction hose to the framing.
- Open the choke (cold start).

- CAUTION!!!
- As soon as the engine roars to life, the vane wheel starts turning and the
exhauster starts sucking – risk of ejected particles.
- Should the exhauster work in workshops or outdoors, avoid directing the
flying leaves/particles in places with motion of persons or animals after
starting. Before start-up tilt the end piece to reduce the flying particles
range. Be careful while working in workshops – danger of suction of
mechanical impurities and debris.

exhauster immediately and contact the authorised service.
