California Proposition 65 Warning: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Setup

Before initial use, familiarize yourself with all components and ensure they are clean and free from damage.

Assembling the Pump

1. Ensure the gauge is securely attached to the MV8510 hand pump.
2. Verify that the vacuum/pressure selector switch operates smoothly.

Connecting Accessories

1. Connect the appropriate length of hose to the pump's vacuum or pressure port as required for your application.
2. Attach the 4.5 oz fluid reservoir when performing fluid extraction or bleeding procedures. Ensure all connections are tight to prevent air leaks.
3. Select the correct adapter for the specific component you are working on.

Operating Instructions

The MV8510 pump can generate both vacuum and pressure. A selector switch on the pump allows you to toggle between these modes.

General Operation

• Switching Modes: Locate the selector switch on the side of the pump. Move it to the 'VACUUM' position for vacuum applications or 'PRESSURE' for pressure applications.
• Releasing Pressure/Vacuum: A release lever is located near the selector switch to safely relieve any accumulated vacuum or pressure.

Brake and Clutch Bleeding

This procedure requires careful attention to fluid levels and proper sealing.

1. Connect the fluid reservoir to the pump and attach the appropriate adapter and hose to the bleeder screw of the brake caliper or clutch slave cylinder.
2. Ensure the bleeder screw is slightly opened according to the vehicle manufacturer's specifications.
3. Set the pump to 'VACUUM' mode.
4. Operate the pump handle to create a vacuum, drawing fluid and air from the system into the reservoir.
5. Monitor the fluid in the hose for air bubbles. Continue pumping until no air bubbles are visible.
6. Close the bleeder screw while maintaining vacuum.
7. Release the vacuum from the pump.
8. Refill the master cylinder with fresh brake fluid as needed throughout the process. Do not allow the master cylinder to run dry.

Vacuum and Pressure Testing

The MV8500 kit is suitable for testing various automotive systems, including fuel, hydraulic, coolant, and differential components.

1. Connect the appropriate adapter and hose to the component being tested (e.g., vacuum lines, fuel pressure regulators, EGR valves, turbocharger wastegates).
2. Set the pump to 'VACUUM' or 'PRESSURE' mode as required by the test procedure.
3. Operate the pump handle to achieve the specified vacuum or pressure reading on the gauge.
4. Observe the gauge for any pressure or vacuum decay, which may indicate a leak or faulty component.
5. Refer to the vehicle's service manual for specific test values and procedures.

Maintenance

To ensure the longevity and optimal performance of your Mityvac MV8500 kit:

• Cleaning: After each use, especially when handling fluids, clean the pump, reservoir, hoses, and adapters thoroughly. Avoid drawing fluids directly into the pump.
• Lubrication: If lubrication is required for the pump's internal components, use silicone oil, DOT 5 silicone-based brake fluid, or vegetable oil. Do not use petroleum-based fluids or sprays (e.g., WD-40, motor oil) as they can damage the tool's seals.
• Storage: Store all components neatly in the provided carrying case in a clean, dry environment.

Troubleshooting
