Setup: Setting Your Combination
Your Zarker XD35 combination lock comes with a factory-set combination, typically found on a sticker on the back of the lock. Follow these steps to set your personalized 3-digit combination:
- Open the Shackle: Align the initial password (factory-set combination) with the red line on the front of the lock. Pull the shackle upwards to open the lock.
- Rotate the Shackle: With the shackle open, turn it 90 degrees counter-clockwise. There is a small groove on the lock body where the shackle will align.
- Set New Combination: While holding the shackle pressed down into the lock body (in the 90-degree rotated position), rotate the dials to your desired 3-digit combination. Ensure the numbers are clearly aligned with the red line.
- Complete Setting: Lift the shackle back up, then rotate it back to its original open position (0 degrees). Scramble the dials to lock the new combination. Your new combination is now set.

Operating the Lock
Using your Zarker XD35 combination lock is straightforward:
- To Unlock: Rotate the dials to your set 3-digit combination, ensuring each number is precisely aligned with the red indicator line. Pull the shackle upwards to open the lock.
- To Lock: Close the shackle by pushing it down into the lock body. Once the shackle is fully seated, scramble the dials to a random set of numbers. This secures the lock.

Maintenance
To ensure the longevity and smooth operation of your Zarker XD35 combination lock, follow these simple maintenance guidelines:
- Keep Clean: Periodically wipe the lock body and dials with a soft, dry cloth to remove dust and grime.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or internal mechanisms.
- Lubrication (Optional): If the dials become stiff over time, a small amount of graphite lubricant (powdered graphite) can be applied to the moving parts. Avoid oil-based lubricants as they can attract dirt.
- Storage: When not in use, store the lock in a dry environment to prevent corrosion.
Troubleshooting
If you encounter issues with your Zarker XD35 lock, consider the following:
- Lock Will Not Open:
- Ensure the combination is correctly aligned with the red indicator line. Even a slight misalignment can prevent opening.
- Verify you are using the correct combination. If you recently changed it, ensure you are using the new code.
- Try rotating the dials back and forth a few times to ensure all internal components are free.
- Difficulty Changing Combination:
- Confirm the shackle is fully pulled up and rotated 90 degrees into the groove before pressing it down to set the new code.
- Ensure the shackle remains pressed down firmly while setting the new numbers.
- Stiff Dials:
- Clean the dials as described in the Maintenance section.
- Apply a small amount of graphite lubricant if cleaning does not resolve the issue.
Note: If the combination is forgotten, there is no master key or override function. The lock will need to be cut or replaced.
