carburetor adJustment

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.

Level 2.

Tools required: Screwdriver, Tachometer

Parts required: None.

NOTE

Every unit is run at the factory and the carburetor is set in compli-

ance with emission regulations. This carburetor does not have

acceleration and high-speed adjustment needles.

Check idle speed and reset if necessary. If a tachometer is available,

idle speed screw (A) should be set to the specications found on page

27 “Specications” of this manual. Turn idle screw (A) clockwise to

increase idle speed; counter clockwise to decrease idle speed.

WARNING

When carburetor adjustment is completed, the cutting attachment

should not move at idle, otherwise serious personal injury may result.
