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

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
