MAINTENANCE 4

4.10 LUBRICATION ____________________________________________________________
The mower was designed for minimum lubrication. Over
greasing will produce high loads on the bearings and
engine; thereby reducing the performance of the
machine.
All maintenance intervals must be performed more
frequently when operating in extremely dusty conditions.
1. Always clean the grease fitting before and after lubri-
cating.
2. Apply grease with a manual grease gun and fill
slowly until grease begins to seep out. DO NOT use
compressed air guns.
3. For smooth operation of pivot points and other
friction points, apply several drops of SAE 30W oil.
