8.4.4. Lubrication of the boom system
Extensions
Clean the surfaces and remove with a spatula all abrasive material (dirt, sand, shavings), and
where possible, the old grease.
• Grease externally the extensions in the low part (less in the upper and side parts).
• Grease internally the extensions in the upper part (less in the lower and side parts).
• In order to internally grease, use the side holes in the extensions (if fitted) and the back closing
plate slots.
• Grease the sliding block area (if fitted) with the extensions retracted and also through two
specific greasing points.
NOTE
To prevent or correct malfunctions
or the “stick-slip” of the
boom extensions operation, we
recommend lubricating the lower
part of the extensions.
If you have any doubt, please
contact your Effer representative.
Extension cylinders support
Grease the extension cylinders support to prevent corrosion and wear.
