Periodic maintenance and lubrication keeps your SHARK CNC running efficiently and smoothly.
If the Pendant buttons stop responding correctly, clean around the screen with a piece of paper.
Use a dry lubricant for the rails, round bars, and leadscrews. Dry lubricant doesn’t attract dust. Purchase Dupont Silicon Teflon at your local Next Wave CNC retailer or online at: NextwaveCNC.com/shop. You will find similar dry lubricant products at your local hardware store.
To lubricate the linear bearings, use the linear bearing grease and nozzle kit from Next Wave. It includes a light lithium grease and a nozzle to attach to a mini grease gun you supply:

Daily
• Check for damaged wires or components. Repair or replace them as needed.
• Check for loose parts. Tighten or adjust as needed.
• Vacuum or dust off machine and components, including the controller and router.
• Wipe down the bars with a soft cloth.
• Clean the leadscrews with a soft brush or vacuum.
• Apply dry lubricant to the guide rods and leadscrews, wiping off the excess with a soft rag.
Monthly or Every 40 Hours of Use
• Deep clean the guide rods and leadscrews with mineral spirits or other mild solvent to remove wood glue and resin.
• Apply a light coat of dry lubricant to the round Y-bars and leadscrews. Wipe off excess with a soft rag.
• Grease the linear bearings (more often if needed) with the Next Wave grease and nozzle kit.
Guide Rail & Bearing Maintenance
X and Z Rails
Dust and debris build-up on the guide rails can have a negative impact on the performance of your machine, so it is important to keep them clean and lubricated. To maintain optimum performance, clean and lube the X and Z rails at least once every 8 hours of operation. While the machine is
stopped, wipe off the rails with a clean cloth or soft brush. After cleaning the rails, lubricate the bearings with a dry lubricant.
X and Z Bearings
The two Z-axis bearings are located behind the router/spindle mount. The two X-axis bearings are located behind the Z carriage. These four bearings require periodic lubrication with light lithium grease included in the linear bearing grease and nozzle kit from Next Wave. Linear Bearing Grease and 6mm Nozzle Kit Available at www.NextWaveCNC.com/shop.
Y Rails (under the machine)
Clean the round Y rails under the machine in the same manner as the X and Z rails. After cleaning the Y rails, apply a dry lubricant then run the machine Y-axis back and forth a few times to distribute the lubricant evenly along the rails.
Y Bearings (under the machine)
The round linear Y bearings under the machine do not require lubrication. Applying dry lubricant to the round rails is sufficient.
