OIL LEAKAGE

⚫

By referring to the following chart, when oil leakage occurs, investigate the cause and

repair accordingly. After fitting the hydraulic breaker on the excavator, sometimes you

may see oil ooze from the breaker. This is grease, which is used in assembly and may

continue for up to 5 hours, but will stop eventually. But please note, oil coming from

section A (See diagram) between the chisel and chisel bushing, this oil is for lubrication

purposes and is normal.

Oil Leakage Location

Cause

Countermeasure

Opening between the chisel
and the chisel bushing

Wear or damage of oil seal.

with the specified torque.

Between the cylinder and the
hose adapter

Wear or damage of O-ring

(*) Replacement.

Looseness of the hose
adapter
