For best results, bearings should be relubricated while in operation. Note:
Due caution for personal safety must be observed when servicing rotating equipment. The grease should be pumped in slowly until a slight bead forms around the seals. This bead, in addition to acting as an indicator of adequate relubrication, provides additional protection against the entry of foreign matter. If necessary to relubricate while the bearing is idle refer to relubrication table for maximum grease capacity for the various size bearings.
Shaft Size | Maximum Grease Capacity of |
| Bearing Chamber in Ounces |
1/2"' to 3/4" | 1/8 |
7/8" to | 3/8 |
5/8 |

Warning: Never make adjustments to belts or pulleys while engine is running!
1.The best tension for a belt drive is the lowest tension at which the belts will not slip under full load.
2.Simply take up the drive until the belts are snug in the grooves. Run the drive for about 15 minutes to "seat" the belts. Then impose the peak load. If the belts slip, tighten them until they no longer slip at peak load.
3. Remember, too much tension shortens belt and | FIGURE 1 | FIGURE 2 | |

4.Check the belt tension frequently during the first day of operation. Check the belt tension periodically thereafter and make any necessary adjustments.
5.The two most common causes of misalignment are shown in the drawing.
a). The engine drive shaft and the blade shaft are not parallel. b). The pulleys are not located properly on the shafts.
6. To check alignment, all you need is a steel straight edge.
