drum Head seals

There is 1 set of drum head seals (Figure 29) that will

require lubrication. Lubricate the grease fitting for each

drum seal every 40 hours of operation using any grade

lithium base grease. Apply grease until visible inside of

mixing drum (over grease). This will purge seal system of

contamination.

smear socket periodically with multi-purpose grease.

This will keep the ball socket well lubricated.

2. Periodically oil pivot points and clamp face surfaces of

3. When parking or storing your mixer. Keep the coupler

off the ground so dirt will not build up in the ball socket.
