Cleaning and lubricating
A pressure washer and mild detergent can be used to clean the attachment. Do not use strong solvents or
spray directly at any hydraulic component. Also mind the labels on the attachment. Lubricate the lubrication
points on the attachment after washing.
Lubrication:
There are several lubrication points on the grapple as shown in the figure above. In addition, depending on the
rotation system, there may be several lubricating points on the rotating joints.
Suitable lubrication interval depends heavily on operating conditions. Adequate lubrication of the joints must
be ensured, and if the joints have become dirty, lubricant must be added; added lubricant will push out dirt
from joints.
Clean the end of the nipple before greasing. Only add the grease amount of a couple of grease press pushes
at a time.
Before longer storage periods touch up the paint where needed, grease the lubrication points, and oil the
visible part of hydraulic cylinder shaft to prevent rust damage.
7.3
Inspection of metal structures
Also the metal structures of the attachment must be inspected regularly. Check visually for damages and
inspect the quick attach brackets and their surrounding area carefully. The attachment must not be used if it is
deformed, cracked, or torn.
Welding repairs are only allowed to be carried out by professional welders. When welding, only methods and
additives suited for steel used in bucket must be used. For more information about repairs contact your
nearest service point.
