HIGH REACH DEMOLITION MANUAL
INSTALLATION AND REMOVAL

FITTING DEMOLITION DIGGING EQUIPMENT. 7
REMARK
It is assumed that the demolition digging equipment is complete
and resting on the ground, with the boom supported by the
Komatsu Digging Equipment Stand (available from your dealer).
WARNING
Make sure that all personnel are a safe distance from the dig-
ging equipment while the machine is moving.
1. With the high reach equipment removed from boom 1, and
demolition boom 1 attached to the base machine, manoeuvre
the machine slowly towards the demolition digging boom.
2. Before arriving at the digging equipment, lower the demolition
boom 1 so that the upper pin hook is able to accept the upper
pin of the exposed end of the demolition dig boom.
CAUTION
It is important that the machine is aligned correctly with the
demolition digging equipment. Otherwise, the pins will be
very difficult to fit or the equipment may fall.
REMARK
The upper pin used to connect the demolition digging boom with
the demolition boom 1 should be retained in the digging boom.
Make sure that the pin is correctly centralised and greased to
accept the demolition first boom.
3. Make sure all of the exposed wear surfaces of the demolition
digging boom and demolition first boom are clean and show-
ing no signs of damage.
WARNING
Do not extend the boom raise cylinders to lift the Digging
Equipment Support off the ground. It may cause damage
and serious injury.
4. Carefully approach the digging equipment, taking care not to
strike it with the machine. Raise the demolition boom 1 to
connect with the upper pin of the demolition digging boom, so
that the weight of the digging equipment is supported by the
demolition first boom.
