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
YOU MAY ADJUST THE IDLE SPEED ONLY by turning the idle speed adjustment screw(T).
During carburettor adjustment, the cutting attachment may move. Pay utmost attention and care to the cutting at-
tachment so as not to get injured by the moving cutter.
When carburettor adjustment is completed, the cutting attachment should not move at idle speed, otherwise serious
personal injury may result.
You must NOT carry out any Carburettor adjustment, other than the idle speed. All other adjustments MUST be per-
formed by an authorized service dealer, or serious personal injury may result due to malfunction of the engine.
When there is trouble with the carburettor, contact an authorized service dealer.
