Adjusting Engine Idle; Adjustment Procedure; Check Unit Condition - Shindaiwa 270 Serie Manual Del Propietário

Adjusting Engine Idle

The engine must return to idle speed
whenever the throttle lever is released.
Idle speed is adjustable, and must be set
low enough to permit the engine clutch to
disengage the cutting attachment when the
throttle is released.

Adjustment Procedure

1. Start the engine, and then allow it to
idle 2-3 minutes until warm.
2. If the cutting attachment rotates at
engine idle, reduce idle speed by turn-
ing the idle adjustment screw counter
clockwise. See Figure 22.
3. If a tachometer is available, the engine
idle speed should be final-adjusted to
3,000 (±250) RPM (min

ALWAYS stop the engine immediately
and check for damage if you strike a for-

equipment.
NEVER allow the engine to run at high
RPM's without a load. Doing so could
damage the engine.
