1. To assure quiet and smooth operation of your roller, please regularly clean and
lubricate the rail tracks and canister. It is recommended every 3 months or 6,000 km,
or when you use it in muddy water, desert, Gobi desert, etc. Please focus on
cleaning the side rails and the canister which may have sand, sludge, gravel and
other sundry inside. Please use the lubricants we offered or other brand silicone
oil-type lubricants after cleaning, and increase the frequency of using lubricants
based on actual situation. Avoid using petroleum-based product on rubber seals.
Lighter oil spray lubes with PTFE (Teflon) seem to work the best when regularly
wiped out and reapplied.
2. Avoid the thicker grease type because they tend to get sticky and gather a lot of
dust and debris and then later dry out. Also Avoid the silicone dry lubes as they tend
to cause squealing noise between the sliding components.
3. To clean the rail tracks, please apply the lubricant to a rag and wipe it inside of
the rail tracks, along the underside of the sweep seal and the top of the wear strip.
Repeat until the dust has been removed. You can also use a high-pressure water gun

if necessary and then make sure all components have been lubricated. Pull back first
and then press the lock to open the roller. Good usage habits can extend product
life. Clean the canister regularly and keep the drain tubes unobstructed, avoid
blocking and keeping water in the canister, sundries may scratch
4. To clean the canister, remove the rail stops, or vertical rails as required, and run
the cover out far enough that you can get into the canister. Apply the lubricant to a
rag and wipe the inside of the canister, including all components inside the canister.
Ensure the Drain Tubes are clear of any debris or blockage. Reassembly the cover.
5. To keep the roller in tip-top condition, we recommend washing it the same as
caring for your truck finish. A lack of proper cleaning and maintenance can affect the
operation of the product and reduce its life.
