III. MAINTENANCE
C. Blade Shaft Bearings
The blade shaft bearings are lubricated and should not require daily lubrication
under normal conditions. However, to assure long life the bearings do need to be
lubricated periodically. The time interval between greasing is dependent on the
running speed and operating conditions. The following chart covers most
situations and can be used as a guide.

Note: Never operate saw without bearing cover in place.
For normal conditions the grease should conform to the NLGI grade two
consistency and be free of any chemical impurities such as free acid or free
alkali, dust, rust, metal particles or abrasives.
For best results, the bearings should be lubricated while in operation.
Note:
Due caution for personal safety must be observed when servicing
rotating equipment.
If necessary to lubricate while the bearing is idle, refer to lubrication table
for the maximum grease capacity for the bearings.
