2. Setup and Installation

Proper installation is crucial for the functionality and durability of your drawer slides. Please follow these guidelines carefully.

2.1 Pre-Installation Requirements

• Drawer Depth: Ensure your drawer has an internal depth of at least 12 inches to 14 inches for the 12-inch slides.
• Clearance: A 0.75-inch (19mm) gap is required on each side (left and right) between the drawer and the cabinet wall. This means the internal cabinet width minus the external drawer width should equal 1.5 inches (38mm).
• Mounting Screws: Mounting screws are not included. Please purchase M5 screws of appropriate length and type suitable for your specific cabinet material and installation scenario.

2.2 Installation Steps

1. Separate the Slides: The drawer slides feature a detachable design. To separate the inner (narrowest) track from the main slide assembly, press and hold the blue lock handle while pulling the inner track outward.
2. Mount Cabinet-Side Slides: Attach the outer slide members to the inside of your cabinet. Ensure they are horizontally aligned and perfectly parallel to each other. Use appropriate M5 screws.
3. Mount Drawer-Side Slides: Attach the inner slide members to the sides of your drawer. Ensure they are also horizontally aligned and parallel to each other, matching the cabinet-side slides.
4. Insert Drawer: Carefully align the drawer-side slides with the cabinet-side slides and push the drawer into the cabinet until the slides fully engage. You should feel a secure connection.

3. Operating Instructions

The YENUO drawer slides are designed for smooth operation and secure locking.

3.1 Full Extension

These slides feature a 3-fold full extension design, allowing the drawer to be pulled out completely. This provides full access to the contents of the drawer without obstruction.

3.2 Locking Mechanism

The slides are equipped with a blue lock handle that provides a hold-still lock feature. When the drawer is fully extended or fully closed, the slides will automatically lock into position. This prevents accidental sliding and keeps the drawer stable and secure.

• To Unlock: Gently press the blue lock handle to disengage the lock and allow the drawer to slide freely.
• To Detach: For complete removal of the drawer, press and hold the blue lock handle while pulling the drawer outward to separate the inner track.

4. Maintenance

YENUO drawer slides are designed for long-term durability with minimal maintenance.

• Cleaning: Periodically wipe the slide rails with a clean, damp cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
• Lubrication: The industrial-grade solid steel ball bearings are pre-lubricated for smooth operation. Additional lubrication is generally not required under normal use. If the slides become stiff over time, a light application of a silicone-based lubricant can be applied to the ball bearings.
• Corrosion Protection: The slides feature an electroplated blue zinc surface treatment, providing excellent oxidation resistance and corrosion protection. This finish ensures a minimum 30-year service life under typical conditions.
• Inspection: Regularly inspect the slides for any signs of wear, damage, or loose fasteners. Address any issues promptly to maintain optimal performance.

5. Troubleshooting

If you encounter issues with your YENUO drawer slides, refer to the following common problems and solutions:

• Drawer does not open to full extension:
  • Check for any obstructions within the slide mechanism or the drawer compartment.
  • Verify that the slides are installed parallel and horizontally aligned. Misalignment can cause binding.
  • Ensure the inner and outer slide members are fully engaged.
• Drawer is stiff or difficult to open/close:
  • Inspect the slide rails for dirt, dust, or debris. Clean thoroughly if necessary.
  • Check for proper alignment of the slides.
  • Apply a small amount of silicone-based lubricant to the ball bearings if needed.
• Locking mechanism fails (does not hold drawer in place):
  • Examine the blue lock handle and its internal components for any visible damage or debris.
  • Ensure the drawer is fully extended or fully closed for the automatic lock to engage.
  • If the lock is damaged, contact customer support for assistance.
• Drawer wobbles or feels unstable:
  • Verify that all mounting screws are securely tightened.
  • Confirm that the drawer and cabinet are structurally sound and can support the load.
  • Ensure the load within the drawer does not exceed the maximum capacity of 250 lbs.

If problems persist after attempting these solutions, please contact YENUO customer support.
