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 (DR)
horizontal on wood blocks (t20)
and remove boom pins (m1 and

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.
