Check the Internal Gear Housing Seal
The most common cause of oil leaks is a worn or damaged gear housing seal. To inspect:
- Remove the tilt-head lock lever and gently tilt the head back.
- Look for oil around the gear housing or the tilt-head hinge.
- If oil is present, the seal may need replacement.
Perform a Safe Fix
- Unplug the mixer and allow it to cool.
- Remove the screws holding the top cover or gear housing (refer to your model’s manual).
- Carefully inspect the seal for cracks or wear.
- If damaged, replace the seal with a compatible part (consult the manufacturer or a repair specialist).
- Reassemble the mixer carefully, ensuring all screws are tightened securely.
Apply Proper Lubrication and Maintenance
After fixing the seal, ensure the gear housing is properly lubricated. Use only manufacturer-approved lubrication to avoid over-lubrication, which can cause leaks. Regularly check for signs of wear and clean your mixer to prevent buildup that can affect internal seals.
Tips and Warnings
- Always unplug the mixer before opening or inspecting internal parts.
- Consult your user manual or contact a professional if unsure about disassembly or seal replacement.
- Using non-approved lubricants can damage internal components or void warranties.
