REMOVAL AND MOUNTING OF HYDRAULIC
HAMMER
REMOVAL FROM THE CARRIER
1. Close pressure and return line shut-off
valves (k4).
2. Disconnect hydraulic hoses (AO) before
laying the hammer down.
3. Cap the pressure and return lines on the
carrier and connect the hammer whip
hoses.
4. Position the hammer assembly (DR)
horizontal on wood blocks (t20) and
remove stick pin (m1) and link pin (m2).
The hydraulic lines must be handled carefully and sealed to
prevent contamination from entering the hammer or the carrier
hydraulic system.
The tool end of the hammer should be set lower than the head
end to prevent moisture from entering the hammer through the
tool area.

2. Align the boom pin holes (m10). Install
the stick pin before the cylinder link pin.
