Lubrication
To reduce the wear caused by the friction caused by the moving parts of the equipment,
it is necessary to carry out a proper lubrication, as indicated below:
a)
Lubricate every grease fitting after 24 hours of service.
1. Be sure about the lubricant quality in relation to its efficiency and purity, avoiding
the use of products contaminated by water, dirt or others.
2. Remove the remainder old grease around the articulations.
3. Clean the grease fittings with a cloth before inserting lubricant and replace the
damaged ones.
4. Introduce enough amount of new grease.
5. Use medium consistency grease.
b)
The roller bearings with oil bath works in constant lubrication, but it is still necessary
to give them the following attention:
1. In a flat place, check the oil level of each bearing before using the disk harrow for
the first time and every day of the first week.
2. Then, start to check weekly.
3. Change all the oil every 1,000 operating hours.
4. Use SAE 140 mineral oil only.
