Internal Cable Sheave Lubrication
A grease gun adapter is required to lubricate the internal
sheaves. The required needle grease gun fitting is:
• A 0.25 inch (6.35 mm) diameter nozzle grease gun tip
(National P/N 955045).
• Contact National Product Support to obtain this tip.
Lubrication of the extend and retract sheaves is as follows:
1. Extend the boom until the grease access holes on the
side of the 2
nd
and 3
rd
sections are lined up.
2. Lubricate the pin for the extend cable sheaves (18) until
a small amount of grease extrudes from the pin. From in
front of the boom, look back through the sheave case at
the pin to determine the amount of grease.
3. This position also aligns the access holes in the rear of
the 1
st
and 2
nd
sections for lubrication.
