Before you start
- If the battery is disconnected or the fuse removed, the exercise function must be reset.
- If the generator has the low speed exercise feature, it was enabled at the factory and needs no adjustment.
Procedure
- For 8 kW models with the mode switch in AUTO, press and hold the EXERCISER switch at least 10 seconds and release; the unit runs about 12 minutes.
- On all other models the display enters an Installation Assistant mode when battery power is first connected.
- The assistant prompts to enter the current date and time, then the exercise day and time.
- If the exercise day or time needs changing, press the escape key to access the main menu.
- Press the left or right arrow key until 'Edit' is flashing and press enter.
- Press the right or left arrow key until the exercise time is displayed and press enter.
- Using the arrow and enter keys set the exercise hour in 24 hour format, then the minute, then the day.
- Once set, the generator will exercise each week at the same time.
