Maintenance

Maintenance, replacement or repair of emission
control devices and systems may be performed by any
repair establishment or individual; however, warranty
repairs must be performed by a dealer or service
center authorized by MARUYAMA Manufacturing
Company, Inc. The 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 a warranty
claim.

Idle Speed Adjustment

This Handheld Blower is equipped with non-adjustable
fuel mixture carburetor. The engine idle speed is the only
adjustment for the operator.
Wear the recommended personal protective equipment
and observe all safety instructions.
When the throttle trigger and the throttle setting lever is
idle position the engine should return to an idle speed
between 2700 and 3300 RPM. The engine should not stall
(stop running) at engine idle speed.
To adjust the engine idle speed, rotate the idle speed
adjustment screw on the carburetor.
• Turn the idle speed screw in (clockwise) to increase
the engine idle speed.
• Turn the screw out (counterclockwise) to decrease
the engine idle speed.
If idle speed adjustment is necessary, and after
adjustment the engine stalls, stop using the Handheld
Blower immediately!
Contact your local authorized MARUYAMA Dealer for
assistance and servicing.
