MAINTENANCE
Daily Service
Handlebar
The handlebar generally requires little or no
maintenance and, when used correctly, should
remain in good, working condition. Inspect the
handlebar occasionally for bending, unusual
cracks, and/or breakage. Replace it
immediately when damaged.
Lubricate the Blade Shaft Bearings
WARNING
DO NOT grease parts with the
motor running.
Lubricating the blade shaft bearings on
schedule increases the floor grinder’s
efficiency and life. Use NLGI No. 1 premium
lithium-based grease when lubricating parts.
Use one-half to one full pump of grease when
lubricating grease fittings.
At the end of each work day, lubricate the two
blade shaft bearings. Locate the upper and
lower blade shaft bearing grease fittings
located under frame base at the front of the
floor grinder. To access the lower blade shaft
bearing, pull down on the flexible hose.
1. Add no more than one pump of bearing
grease into each of the two blade shaft
bearing grease fittings.

Belt Tensioning
When tensioning belts, DO NOT exceed the
manufacturer’s recommended belt tension
settings as specified in Appendix B.
NOTE: Over-tensioning belts may damage the
motor. Under-tensioning belts may cause
slippage, shorter belt life, and/or poor floor
grinder performance. Squealing belts indicate
looseness
