5. Installation (Setup)
Professional installation is recommended due to the electrical nature of this component.
5.1. Preparation
- Disconnect Power: Unplug the pressure washer from the electrical outlet.
- Access Capacitor: Locate and access the capacitor compartment on your pressure washer. This may require removing covers or panels.
- Discharge Old Capacitor: CRITICAL SAFETY STEP. Using a properly insulated tool (e.g., a screwdriver with an insulated handle), carefully short the terminals of the old capacitor to discharge any stored electricity. You may see a spark. Hold the short for a few seconds to ensure full discharge.
5.2. Removal of Old Capacitor
- Note Wiring: Carefully observe and note the wiring connections to the old capacitor. Taking a photograph can be helpful.
- Disconnect Wires: Gently pull the wires off the terminals of the old capacitor.
- Remove Capacitor: Unmount the old capacitor from its housing or bracket.
5.3. Installation of New Capacitor
- Mount New Capacitor: Secure the new RYOBI OEM 820270012 capacitor in the same position as the old one.
- Connect Wires: Reconnect the wires to the terminals of the new capacitor, ensuring they match the original configuration. Ensure connections are firm.
- Secure Covers: Replace any covers or panels that were removed to access the capacitor.
5.4. Testing
- Reconnect Power: Plug the pressure washer back into the electrical outlet.
- Test Operation: Attempt to start the pressure washer. It should now start smoothly if the capacitor was the issue.
6. Operation
Once installed, the capacitor operates automatically as part of the pressure washer's motor starting circuit. No user interaction is required for its operation. Its function is to provide the necessary electrical boost to initiate the motor's rotation.
7. Maintenance
The RYOBI OEM 820270012 capacitor is a sealed unit and requires no routine maintenance. However, it is advisable to:
- Periodically inspect the capacitor and its connections for any signs of damage, corrosion, or loose wiring.
- Ensure the area around the capacitor is kept clean and free from debris to prevent overheating.
8. Troubleshooting
If your Homelite pressure washer exhibits the following symptoms after capacitor replacement, or if you suspect a capacitor issue:
- Motor Hums but Does Not Start: This is a common symptom of a faulty start capacitor.
- Motor Does Not Start At All: While this can indicate various issues, a completely failed capacitor can be a cause.
- Slow or Weak Start: A capacitor that is losing its capacitance may result in a sluggish motor start.
If these issues persist after replacing the capacitor, further diagnosis of the pressure washer's motor or electrical system by a qualified technician may be necessary.
