How often do I grease the bearings on my T2?

Greasing intervals on the Twister T2 Trimmer

There are two grease fittings on each end of the T2. Do not grease these fittings. These fittings are for greasing newly installed bearings only. Over greasing the bearing will cause the seals to pop out. Bearings should be replaced with the reel blade and bedknife every 1000 hrs
