WARNING
The blades must not move at idle, otherwise serious personal injury
may result. Periodic carburetor adjustment may be necessary to as-
sure blades do not move at idle.
If blades move, readjust carburetor according to these instructions,
or see your Shindaiwa Dealer.
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel
break-in 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 start-
ing, 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 Shindaiwa
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.
