Self-Propel Drive Bail (Self-Propelled Units Only)

Located on the upper handle as shown in Figure 4.

When the self-propel drive bail is squeezed, the unit will move forward based on how far the bail

is depressed toward the handle. When this bail is released the unit will stop moving.

Throttle-Choke Lever (ECXHN21)

Located on the left side of the handle bar.

The lever is used to control engine speed. Moving the throttle to the full forward (Choke) position will place the lever in the choke position. The choke aids in starting a cold engine. Moving the throttle control forward will increase engine speed and moving it to the rear will decrease engine speed.

Choke Control (ECXHNBBC21)

Located on the front left side of the engine as shown in Figure 9.

The choke aids in starting a cold engine. Pulling outward will place the control in the choke position. Pushing the control inward shuts off the choke.

Blade Control Lock Lever (Blade Brake Clutch Units Only)

The blade control lock lever is located on the right side of the handle next to the Blade Control Bail as shown in Figure 4.

Moving the blade control lock lever into the full forward position releases the blade control bail. Squeezing the blade control bail against the handle engages the blade. Releasing the blade control bail automatically disengages the blade. The blade control lock lever will reset to lock the blade control bail.

Engine Stop Switch
