This is a new, unused, Genuine HILTI Rubber Shock Absorber O-Ring (Damping Element) for the Striking Mechanism on the Front Ram for the following models only:
HILTI TE 30-A36 AVR (02-03), TE 30 ATC AVR (02), TE 30 AVR (02) – Second Generation Model
Oil heats up during long operating periods of the tool and it becomes aggressive towards this part. The shock absorber inflates its size from the temperature and loses its function to push the strike piston back on time. This causes an imbalance of the motion between the striker and drive piston and can be one of the reasons a connecting rod breaks. A worn out absorber can also be one of the causes for a lower striking force.
Machine lubrication is essential for all rotary hammer drills.
Power tool reliability and life expectancy rely on the right methods of lubrication, the right quantities and the appropriate application procedures. It is important to use the right type of oil and grease, which is best suited to the machinery’s optimal functioning and recommended by the manufacturer.
Replace the shock absorber o-ring and fill new original HILTI oil and grease for a quality repair.
