times. Always wear gloves to help pro-
tect your hands and fingers from injury.
• Do not hold any part other than the han-
dle when adjusting the angle of the blades.
• Stop the engine when adjusting the
angle of the blades.
Note: Never use the unit if the blade angle is
not 48 degrees upwards to 84 degrees
downward.
1. First stop the engine. Next attach the blade cover.
2. Turn the clamp knob counter clock wise until the
clamp knob stops. Angle adjustments are not pos-
sible without completely loosening the clamp

lock lever when adjusting the angle of the blades.

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 autho-
rized by MARUYAMA Manufacturing Company, Inc.
The use of parts that are not equivalent in performance
and durability to authorized parts may impair the effec-
tiveness of the emission control system and may have a
bearing on the outcome of a warranty claim.
• Idle speed adjustment should be
checked each time the unit is operated.
Maintenance on today's low-emission engines is
even more critical for longest life and best perfor-
mance. Particularly critical are air and fuel filters,
spark plug heat range, cooling air intake area and
proper gaps of coil and plug.

Idle Speed Adjustment

This Multi-Cutter is equipped with non-adjustable fuel
mixture carburetor. The engine idle speed is the only
adjustment for the operator.
The Attached Tool may be rotating/moving during idle
speed adjustment. Wear the recommended personal pro-
tective equipment and observe all safety instructions.
Keep hands and body away from the Attached Tool.
