This symbol is located in various locations on the motorcycle to inform you that exposure to high voltage can cause shock, burns, and even death. The high voltage components on the motorcycle should be serviced by technicians with special training.

High voltage cable or wiring has an orange covering. Do not probe, tamper with, cut, or modify high voltage cable or wiring.

This manual covers the following motorcycles:

• Zero S: Street

- Cast Wheels

- Street Tires

• Zero SR: Street - Max Performance

- Cast Wheels

- Street Tires

• Zero DS: Dual Sport

- Cast Wheels (19-inch diameter front)

- Dual Sport Tires

• Zero DSR: Dual Sport - Max Performance

- Cast Wheels (19-inch diameter front)

- Dual Sport Tires

Caution: Brake fluid may irritate eyes and skin. In case of contact, take the following actions:

• Eye Contact-rinse thoroughly with water

• Skin Contact-wash with soap and water

• If Ingested-contact a physician immediately

Caution: Approved safety glasses and gloves should be worn when performing this procedure to reduce the chance of personal injury.

Caution: Road test a motorcycle under safe conditions and while obeying all traffic laws. Do not attempt any maneuvers that could jeopardize the motorcycles control. Failure to adhere to these precautions could lead to serious personal injury and motorcycle damage.

Notice: Avoid spilling brake fluid onto painted or other surfaces, electrical connections, wiring, or cables. Brake fluid will damage painted or other surfaces and cause corrosion to electrical components. If any brake fluid comes in contact with painted surfaces, immediately flush the area with water. If any brake fluid comes in contact with electrical connections, wiring, or cables, use a clean shop cloth to wipe away the fluid.

Notice: Replacement fasteners must be the correct part number for that application. Use the correct fastener in the correct location. Fasteners requiring the use of thread-locking compound are specified in the repair procedure; refer to the product manufacture for proper usage. Always use new lock nuts, lock washers and cotter pins. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener contact surfaces unless specified in the procedure. Coatings affect fastener torque and joint clamping force and may damage the fastener.

Caution: Always perform the High Voltage Discharging procedure prior to servicing any High Voltage component or connection. Proper procedures must be followed.

Failure to follow the procedures may result in serious injury or death.

• Always verify that the high voltage has been disabled before working on or around high voltage components, wires, cables, or harnesses.

• Remove all metal objects such as rings and watches.

• Always tighten the high voltage terminal fasteners to the specified torque. Insufficient or excessive torque will cause malfunctions or damage.

• After finishing work on the high voltage system and before turning the key ON.

• Verify high voltage system integrity and that all connectors and covers are installed.

• Verify that all tools or loose components have been removed.

Caution: Exposure to high voltage can cause shock, burns, and even death. The high voltage components on the motorcycle should only be serviced by technicians familiar with the circuit/system operation. Refer to System Description and Operation.

High voltage components are identified by labels. Do not remove, open, take apart, or modify these components. High voltage cable or wiring has orange covering. Do not probe, tamper with, cut, or modify high voltage cable or wiring.

Whenever there is an excessive amount of current flowing through a circuit, the fusible element will melt and create an open or incomplete circuit. Fuses are a one-time protection device and must be replaced each time the circuit is overloaded. Replace the fuse with one of equal current and voltage rating. If the fuse melts repeatedly, inspect the circuit for an overload or short.

Fuse Center Location

The 12-volt fuse center is located on the left side of the frame under the seat. Remove the seat to gain access to the 12 volt fuse center.

Important:

• Perform a thorough inspection of the entire motorcycle at every service interval. Replace any parts found to be worn or in need of replacement.

• Use only genuine Zero or Zero-recommended parts and lubricants/cleaners or their equivalent. Parts that do not meet Zero’s design specifications may damage the motorcycle and/or void the warranty.

Caution: Refer to Road Test Caution in General Information.

Caution: Road test a motorcycle under safe conditions and while obeying all traffic laws. Do not attempt any maneuvers that could jeopardize the control of the motorcycle. Failure to adhere to these precautions could lead to serious personal injury and motorcycle damage.

Before the road test, ensure the following:

• The exterior lighting is working correctly.

• Tire pressure is correct.

During the road test:

• Perform the test only when traffic conditions permit.

• Operate the motorcycle in a controlled, safe manner.

• Observe all traffic regulations.

• Observe any unusual vibrations.

o When braking

o When coasting

o When accelerating

o When regen braking

• Observe any unusual sounds.

Choose different road surfaces when test driving to verify that the condition is not related to road surfaces. Observe where the problem condition is located: Front, back or under the motorcycle. If the condition is something that is heard or felt, driving a similarly equipped motorcycle may determine if the issue is an operating characteristic of the motorcycle.

Use only Zero specified tools when servicing the motorcycle. The motorcycle contains a mix of metric and standard fasteners. Use of the incorrect tool or fastener may damage the motorcycle.

All dealers should have the following:

CAUTION: Under-inflation is the most common cause of tire failure and may result in severe tire cracking, tread separation, “blowout,” or unexpected loss of motorcycle control causing personal injury and possible death.

The tire pressure is checked using an accurate gauge when the tires are cold. This means that the tires have not been ridden on for 3 hours. Always replace the valve stem cap when finished.

Important: Using the following steps of the vibration diagnostic process will help you to effectively narrow-down and pin-point the search for the specific source of a vibration concern and to arrive at an accurate repair.

Vibration Diagnostic Process

1. Gather specific information on the customer's vibration concern.

2. Perform the road testing steps in sequence as identified in Road Testing Procedure in order to duplicate the customer's concern and evaluate the symptoms of the concern under changing conditions. Observe what the vibration feels like and what it sounds like. Observe when the symptoms first appear, when they change, and when they cease.

3. Determine if the customer's vibration concern is truly an abnormal condition or something that is potentially an operating characteristic of the motorcycle.

4. Systematically eliminate or 'rule-out' possible motorcycle systems.

5. Focus diagnostic efforts on the remaining motorcycle system and systematically eliminate or "rule-out" possible components of that system.

6. Make a repair on the remaining component, or components, which have not been eliminated systematically, and must therefore be the cause of the vibration.

7. Verify that the customer's concern has been eliminated or at least brought to an acceptable level.

8. Again perform the road testing steps in sequence in order to verify that the vehicle did not have more than one vibration occurring.

Preliminary Visual/Physical Inspection

• Inspect for aftermarket equipment and modifications, which could affect the operation of the motorcycles rotating component systems.

• Inspect the easily accessible or visible components of the motorcycles rotating component systems for obvious damage or conditions, which could cause the symptom.

• Inspect the tire inflation pressures for the proper pressure.
