The grease lubrication system is a critical part of the Haas machine and it has very precise metering units at all of the lubrication points. The slightest amount of contamination in the system can clog these fittings and will eventually cause damage to the linear motion components. It is critical that the system stays clean every time the canister is refilled. It is also critical that the pickup strainer is upgraded to the one currently used in production. See detailed instructions below.
