OPERATING TIME
After 1 HOUR
After 3 HOURS
NOTE: The scheduled maintenance of the air fi lter is established for the standard operation
of the machine in well-ventilated spaces outdoors. In closed and particularly dusty spaces,
cleaning or changing the fi lters more frequently may be necessary, especially if starting-
up the engine is diffi cult or if there is a reduction in power.
8.1) Engine fi lter cleaning
The engine's fi lter system comprises a primary fi lter (S) and a
secondary paper fi lter (P).
Not maintaining the fi lters properly can cause:
– Diffi cult or impossible start-up of the engine
– Reduction in engine power.
– High consumption.
– Carburettor malfunction.
– Unnecessary wear on engine parts.
– Deposits on the spark plug.
– The machine not being able to carry out cutting
in automatic mode.
• Primary sponge fi lter (S) (spare part code: 6003910)
– Remove the top engine cover by unscrewing the 2
Torx screws with the tool supplied.
– Take the fi lter out and wash it carefully with warm
water and soap, then rinse it well with clean water.
Squeeze the fi lter well and dry it.
– Before remounting it, carefully oil the fi lter.
It is important that the fi lter is well-oiled, in order
to do this we advise putting it in a bag, adding oil,
spreading it evenly over the fi lter then squeezing it
to get rid of excess oil.
Do not use normal engine oil for this purpose,
contact Cembre for suitable oil.
NOTE: Do not clean the fi lter with compressed air as
high pressure could damage the sponge.
