Maintenance and care

If you have any questions or problems, please contact your dealer.
General maintenance
IMPORTANT
Maintenance, replacement, or repair of emission control devices and system may be performed by any repair establishment or
individual. However, warranty repairs must be performed by a dealer or service center authorized by YAMABIKO CORPORA-
TION and use of parts that are not equivalent in performance and durability to authorized parts may impair the effectiveness of
the emission control system and may have a bearing on the outcome of the warranty claim.
Non-standard accessories, cutting attachment, or replacement parts may not operate properly with your unit and
may cause damage and lead to personal injury.
Before performing any maintenance, repair, or cleaning work on the unit, make sure the engine and cutting attach-
ment are completely stopped. Disconnect the spark plug wire before performing service or maintenance.
Operating the engine without a silencer, or with a silencer that is damaged or improperly installed, can increase en-
gine noise sufficiently to cause hearing loss.
Carburettor adjustment
When carburettor adjustment is completed, cutter blade should not move at idle, otherwise serious personal injury may
result.
When starting, idle speed adjuster (T) should be adjusted not to move the cutter blade.
When there is some trouble with the carburettor, contact your dealer.
T: Idle speed adjuster
