Safety Information
Always read and understand all instructions before using the Werner AC78 Quickclick Stabilizer. Failure to follow instructions can result in serious injury or death. Ensure all components are securely attached and in good working order before each use. Do not use this stabilizer on Type III (200 lbs) aluminum, Type II (225 lbs) fiberglass extension ladders, or MT series ladders. Do not use in conjunction with ladder jacks using planks or stages. Always maintain three points of contact when climbing or descending the ladder.
Setup and Installation
- Step 1: Install Tubing Caps and Rubber Pads. Insert the tubing caps and rubber pads onto the ends of the stabilizer arms. These non-marring caps protect the work surface.

- Step 2: Slide on Paint Bucket Hanger. Slide the paint bucket hanger onto one of the stabilizer arms. Ensure the hook of the hanger faces towards the house or work surface when the stabilizer is installed.

- Step 3: Insert Outriggers into Stabilizer. Insert the outrigger arms into the main stabilizer body, aligning the holes.
- Step 4: Lock with Locking Pins. Secure the outriggers by inserting the locking pins through the aligned holes. Ensure the pins are fully engaged to prevent accidental detachment.
- Step 5: Remove Retainer Pin. Before attaching to the ladder, remove the retainer pin from the stabilizer's clamping mechanism.
- Step 6: Slide Stabilizer onto Ladder. From the backside of the ladder, slide the stabilizer over the top two rungs. Ensure the stabilizer is centered and fully seated on the rungs.

- Step 7: Insert Retainer Pin. Once the stabilizer is properly positioned, insert the retainer pin to lock the stabilizer securely onto the ladder. Verify that the locking mechanism swings up into position and is fully engaged before applying any weight to the ladder.

Operating Instructions
With the Werner AC78 Quickclick Stabilizer securely attached to your extension ladder, you can now position the ladder against a wall or work surface. The stabilizer's arms will provide a 10-inch standoff, allowing you to work around windows, gutters, or other obstacles without damaging the surface or compromising ladder stability. The integrated paint can hook provides a convenient place to hang a paint bucket or other tools, keeping them within easy reach while you work.

Maintenance
- Inspect the stabilizer before each use for any signs of damage, wear, or loose components.
- Ensure the rubber end caps are intact and not worn down, as they are crucial for protecting surfaces and preventing slippage. Replace if necessary.
- Check that all pins and locking mechanisms operate smoothly and securely.
- Clean the stabilizer with a damp cloth as needed. Avoid using harsh chemicals that could damage the aluminum or rubber components.
- Store the stabilizer in a dry place when not in use to prevent corrosion.
Troubleshooting
If you encounter issues with your Werner AC78 Quickclick Stabilizer, consider the following:
- Stabilizer feels loose on the ladder: Ensure the retainer pin is fully inserted and the locking mechanism is engaged. Verify that the stabilizer is placed over the top two rungs as instructed.
- Rubber end caps are slipping or worn: Replace the rubber end caps immediately. Worn caps can compromise safety and damage surfaces.
- Difficulty installing/removing: Check for any debris or obstructions in the quick-release mechanism. Ensure the spring-loaded latch operates freely.
