Engine Brake Switch, Optional

The engine brake switch controls the degree of engine braking. Normally there are two paddle switches, a two-position On/Off Switch to activate the engine brake, and a two-position HI-LO Switch to control the amount of engine braking.

To turn the two-position On/Off Switch on, raise the paddle. When the two-position switch is on, an amber LED (light-emitting diode) illuminates inside the switch.

To turn the two-position HI-LO Switch on high, raise the paddle (at the HI-LO icon). To turn the two-position HI-LO Switch on low, lower the paddle (at the ENG BRK legend). See Fig..

A three-position switch is used on MBE900 engines equipped with both the regular engine brake and the constant-throttle (decompression) brake. It works the same as the two-position HI-LO switch, except that there is a third (off) position when the switch is left at its normal position.

The engine brake turns off automatically or when the clutch pedal is pressed. On vehicles without a clutch pedal, the brake pedal can be used to deactivate the engine brake. For more information about engine brake operation, see General Information.

When the panel lights are on, the HI-LO icon is backlit in amber on the HI-LO switch. On both switches, the ENG BRK legend is backlit in green when the panel lights are on.
