WE want you to be entirely satisfied with the performance of your Harley-Davidson. We want to see it give you many thousand miles of satisfactory service. With a reasonable amount of care and attention, your Harley-Davidson is going to serve you mighty well. To help you give it the proper care, this hand book is published.

This hand book is not intended to make a mechanic of every rider; therefore, it does not cover the overhauling of such units as the motor, generator and transmission. Work of this kind requires the attention of a skilled motorcycle mechanic and the use of special tools and equipment. Your nearest Harley-Davidson dealer has the proper facilities for handling this work. He also has a complete stock of genuine Harley-Davidson parts.

If an}’ questions arise that this book does not cover, get in touch with your dealer or write our Service Department.

Return your registration card to the factory promptly.

OPERATING INSTRUCTIONS The Importance of Correct Lubrication

To insure long and satisfactory service from your motorcycle, lubricate it properly—especially your motor. The motor requires a special oil, because it is air cooled and operates at high temperatures.

We recommend the use of genuine Harley-Davidson oil, which is refined to our specifications. We furnish this oil for the protection of Harley-Davidson riders. Your dealer can supply you.

Don’t take a chance with an oil of unknown quality.

Become Familiar With the Operation of All Controls Before Starting Motor or Riding Machine

1. Right hand grip is the throttle (carburetor) control; turn outward to close throttle; turn inward to open throttle.

2. Left hand grip is the spark control; turn inward to advance spark; turn outward to retard spark. Fully advanced is the proper normal running position. Retard spark part way to prevent motor laboring and knocking when in high gear and pulling a heavy load at low speed, on bad hills, etc. Always start motor with spark fully advanced, or nearly so. If motor has a tendency to kick back, it is all right to retard spark slightly.

3. The foot pedal at left footboard is the clutch pedal; rocking it backward releases clutch; rocking it forward engages clutch.

4. Gear shifter lever is mounted on left side of tank. Shifter gate through which lever works is marked with four positions. Shifter lever must be operated in conjunction with the clutch. Before shifting from one position to another, the clutch must be fully released. When cranking motor, shifter lever must be in NEUTRAL position and clutch engaged.
