3. Setup and Installation
This knob is designed for easy replacement on compatible Ambach appliances. Ensure the appliance is turned off and cooled down before proceeding with installation.
- Verify Compatibility: Confirm that your appliance model (GH-45, GH-90-BF, GH-45-D, GH-45-G, GH-90) and the control shaft dimensions (10 x 8 mm, flat axle, left alignment) match the specifications of this knob.
- Remove Old Knob (if applicable): Gently pull the existing knob straight off the control shaft. Avoid twisting or forcing, as this may damage the shaft.
- Clean Shaft: Ensure the control shaft is clean and free of grease or debris.
- Install New Knob: Align the D-shaped opening on the back of the new Ambach knob with the flat side of the control shaft. Push the knob firmly onto the shaft until it is fully seated.
- Test Functionality: Once installed, gently turn the knob to ensure it rotates smoothly and engages properly with the appliance's control mechanism.
Caution: Do not apply excessive force during installation. If the knob does not fit, re-verify compatibility.
4. Operating Instructions
The Ambach Knob functions as a direct replacement for the original control knob on your Ambach appliance. Its operation is identical to the knob it replaces.
- Turning On/Off: Rotate the knob to the designated 'On' or 'Off' positions as indicated on your appliance's control panel.
- Adjusting Settings: For appliances with variable settings (e.g., flame intensity on a gas stove), rotate the knob clockwise or counter-clockwise to adjust to the desired level.
- Engagement: Ensure the knob is fully pushed onto the shaft for proper engagement with the internal control mechanism.
Important: Always refer to your specific appliance's user manual for detailed operating procedures and safety guidelines.
5. Maintenance and Care
Proper maintenance ensures the longevity and appearance of your Ambach Knob.
- Cleaning: Wipe the knob regularly with a soft, damp cloth. For stubborn stains, a mild, non-abrasive cleaner can be used.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the knob's finish.
- Inspection: Periodically check that the knob remains securely attached to the control shaft. If it feels loose, gently push it back into place.
