A quick check and a dab of grease can save you a lot of trouble down the road.
Applying the Lubricant
Once you’ve identified the lubrication points and chosen the right grease, the application process is relatively straightforward. If your sprayer has grease fittings (zerks), use a grease gun to apply the lubricant. For other areas, use a small brush or a clean cloth to apply a thin, even coat of grease. Avoid over-applying, as excess grease can attract dirt and debris.
Cleaning Before Lubricating
Before applying fresh lubricant, it’s crucial to clean the areas you’ll be lubricating. This removes any old, dried-out grease, dirt, or paint residue that can interfere with the fresh lubricant’s effectiveness. Use a clean cloth or brush to wipe down the lubrication points. A little solvent might be necessary for stubborn residue, but be sure to use a solvent compatible with your sprayer’s components. Consult your manual for guidance.
Monitoring for Wear and Tear
While regular lubrication helps prevent wear and tear, it’s essential to keep an eye on the condition of the moving parts. Look for signs of excessive wear, such as scoring, pitting, or deformation. If you notice any issues, address them promptly to prevent further damage and potentially costly repairs. Replacing worn parts early can extend the life of your sprayer significantly.
