1. Disengage clutch, if equipped, controlling engine power
driveline.

IMPORTANT: Before stopping an engine that has

been operating at working load, idle
engine at least 2 minutes at 1000—1200
rpm to cool hot engine parts.

Engines in generator set applications
where the ECU is locked at a specified
speed and no slow idle function is
available, run engine for at least 2
minutes at fast idle and no load.

2. Run engine at 1000—1200 rpm for at least 2 minutes
to cool.

Panels with High-Low Speed Select Rocker Switch (B)
only: Set rpm using Bump Speed Enable Switch (C) with
Speed Select Rocker Switch (D).

Panels with optional Analog Throttle (E): Set either
High-Low Speed Select Switch (B) or Analog Throttle (E)
to low idle, and set desired speed with remaining control.

NOTE: Engine Control Unit (ECU) reads the higher of the

High-Low Speed Select Rocker Switch or the
Analog Throttle(s) Speed settings.

3. Push in on analog throttle potentiometer handle (if
equipped) so that engine goes to slow idle, or set slow
speed with High-Low Speed Select Rocker Switch.

4. Turn key switch (A) to “OFF” position to stop the
engine. Remove ignition key.

IMPORTANT: Make sure that exhaust stack rain cap

(F) is installed when engine is not
running. This will prevent water and dirt
from entering engine.
