Before lubricating the leadscrew, clean it first with mineral spirits. A stiff brush works well to help clean out the threads. Make sure to move the carriage out of the way, so you can clean the entire length of the leadscrew.

Apply a thin coat of oil along the length of the leadscrew. Use a stiff brush to make sure the oil is applied evenly and down into the threads.

Note: In some environments, abrasive material can become caught in the leadscrew lubricant and drawn into the half nut. In this case, lubricate the leadscrew with a quality dry lubricant.

Lubrication Frequency

Before and After Use

Proper lubrication of ball oilers is done with a pump-type oil gun that has a plastic or rubberized cone tip. We do not recommend using a metal needle or lance tips that can push the ball too far into the oiler, break the spring seat, and cause the ball to fall into the oil galley.

Lubricate the ball oilers before and after machine use, and more frequently under heavy use. When lubricating ball oilers, first clean the outside surface to remove any dust or grime. Push the rubber or plastic tip of the oil can nozzle against the ball oiler to create a hydraulic seal, then pump the oil can once or twice. If you see sludge and contaminants coming out of the lubrication area, keep pumping the oil gun until the oil runs clear. When finished, wipe away any excess oil.

Add oil to the feed control lever gearing oil cup until the cup is full. The oil will slowly drain onto the gearing.

Refer to Figures 114–116to identify the locations of each oil device.

Leadscrew End Bearing

To check the oil level, remove the fill cap and look inside the reservoir (Figure 116). The oil level must remain full to keep the leadscrew bearing adequately lubricated. Pour oil in the reservoir until it is as full as possible without overflowing.
