After Each Hour; Every 5 Hours; Out Of Service Protection (Storage); Removing The Sickle Knife Assembly - Simplicity 707 Owner's Manual

AFTER EACH HOUR
To get maximum life and smoothest operation from the
sickle knife, a few drops of engine oil should be placed on
it and the wear plates about once each hour of operation
(Figure 16, Item C),
EVERY FIVE HOURS
A multi-purpose lithium soap base grease designed to operate
at high temperatures must be used in the lubrication of your
sickle bar mower. This grease is available from your Sim¬
plicity dealer. See figure 21. The five grease fittings (A)
should be lubricated until grease is seen forced from the
bearings. Grease fitting (B) should be lubricated with about
five shots or until the grease is seen forced out of the as¬
sembly, whichever occurs first.
A film of grease should be placed on the break away latch,
(Figure 8, Item F).
A few drops of engine oil placed on pivot points and wear
surfaces will help reduce wear. Some of the most important
ones are listed below:
