9.4  Grease Points

IMPORTANT!  Do not over grease a bearing. Too much 
grease can cause the bearing seals to fail.

Look for this type of label on the machine. Each 
label identifies a grease point and shows the 
greasing interval in hours.

For grease specifications, see 

Grease on page 48.

• 

Use a clean cloth to clean each grease fitting before you 
apply grease. This prevents grease and dirt from getting 
inside the component.

• 

Use a hand-held grease gun to apply 

one pump

 of grease 

to each grease point.

• 

If a grease fitting is damaged, replace it immediately.

• 

If a grease fitting does not accept grease:

a. Remove the grease fitting.
b. Clean the passageway behind the grease fitting.
c. Clean the grease fitting thoroughly or get a new grease 

fitting.

d. Install the grease fitting.
