Monitor hydraulic oil quality through regular sampling to detect contamination before it damages the sealed system. Inspect the accumulator charge pressure periodically to ensure consistent hammering force and prevent internal component fatigue. Check hydraulic couplings and hoses for wear or leakage, as the sealed system relies on clean fluid to lubricate the two moving parts. Verify that the hydraulic powerpack output matches breaker requirements to prevent under-performance or excessive wear.

Replace worn chisel or moil point steels promptly to prevent damage to the rammer stem and internal breaker components. Inspect and replace seals in the hydraulic circuit if external leaks develop, as the sealed system is designed to eliminate exhaust port leaks. Check the charging adaptor and pressure settings to ensure proper hydraulic flow. Address any loss of striking force by inspecting the accumulator and internal valve assembly for blockage or wear.

Perform a full breaker dismantling and inspection when striking force drops significantly or internal wear is suspected. Reassemble using specified high-strength bolts, as standard bolts cannot withstand the tensile loads. Inspect the rammer and guide bushings for wear; replace if clearances exceed limits to prevent binding. Clean all internal components during overhaul to remove debris that could impair the constant lubrication system or valve operation.

In cold temperatures, verify hydraulic fluid viscosity and accumulator pressure to prevent freezing and sluggish operation. In high-temperature environments, monitor hydraulic oil temperature to prevent seal degradation and ensure adequate cooling. Keep all decals clean and readable for safety compliance. Protect the hydraulic couplings from debris and damage when not in use. Ensure the breaker is matched to the host machine's weight and hydraulic output for optimal performance in varying conditions.
