PREVENTATIVE MAINTENANCE

This section contains basic preventative maintenance and troubleshooting
information.

To maintain proper dynamometer operation, Dynojet recommends you make routine
checks of the dyno.

• Drum—keep the drum clean and keep all objects clear of the drum.

• Carriage Slide—keep the carriage slide clean and lightly lubricated.

DJUSTING

THE

RAKE

Use the following instructions to prevent the brake from dragging.

Remove any vehicles from the dyno.

Push the brake pedal until it stops.

Using your hand, turn the drum.

Verify the brake is not dragging.

If the brake is dragging, adjust the brake.
Using a 7/16 open end wrench, adjust the brake stop bolt until there is no brake
drag.

Note:

Adjusting the bolt too loose or too tight can cause brake drag.
