Lubrication

Lubrication points

The simplest way to extend the lifetime of your backhoe and prevent possible 

interruptions during working is to lubricate it as described below:

Every 10 hours of work, lubricate the articulations through the grease fittings in the 

following way:

• Be sure about the lubricant quality as its efficiency and purity, avoiding the use of 

products contaminated by water, earth and others.

• Remove the remainder old grease around the articulations.
• Clean the grease fitting with a cloth before inserting lubricant and replace the 

defective ones.

• Introduce an enough amount of new grease.
• Use medium consistency grease.

Lubricate every 10 hours of service.
