NOTICE
Lubricating Grease Fittings
Failure to lubricate the drum bearing grease fittings periodically will cause the dumping mechanism to stiffen, making the mixing drum hard to dump.

Grease Fittings (Zerk) Maintenance (Electric Motor)
1.1.There are two grease (Figure 18) fittings at each end of the electric motor that will require lubrication. Lubricate these fittings about every 16 months.
2.Use Poleyrex EM (Exxon Mobil) or equalivant lubricant. Clean grease fitting, apply grease gun to fitting (1/2 shot). Remember too much grease or injecting grease too quickly can cause premature bearing failure. Slowly apply the recommended amount of grease, taking a miniute or so to apply.
