IMPORTANT

carbon every 3 months or 90 hours of operation in order to maintain
this engine within the emissions durability period. ECHO strongly
recommends that you return your unit to your ECHO dealer for this
important maintenance service.

CARBURETOR ADJUSTMENT

Engine Break-In
New engines must be operated for a minimum of two tanks of fuel before
carburetor adjustments can be made. During the break-in period, your
engine performance will increase and exhaust emissions will stabilize.
Idle speed can be adjusted as required.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting,
emission, and durability performance up to 1,000 feet above mean sea
level (MSL). To maintain proper engine operation above 1,000 feet
MSL the carburetor must be adjusted by an authorized ECHO service
dealer.
IMPORTANT
If the engine is adjusted for operation above 1,000 feet MSL, the
carburetor must be re-adjusted when operating the engine below
1,000 feet MSL, otherwise severe engine damage can result.
Idle Speed Adjustment
Idle speed adjustment may be required periodically to comply with
specifications for this unit. See page 25, "Specifications," for correct
idle speed.
