WARNING
Close the protective shield on the
operator’s cab to prevent possible
injury from flying rock splinters dur-
ing hammer operation.
All persons in the immediate area,
including the carrier operator, must
wear ear protection.
The Street Hammer shall only be
operated from the operator’s seat
and shall not be put into operation
until both carrier and hammer are in
the correct position.
~
WARNING
Immediately cease operating the
Street Hammer if anyone moves
into the danger area, which is
greater for hammer operation than
for carrier operation due to the risk
of flying debris.
When working with a hydraulic
hammer, operation of the carrier
is governed by the carrier manufac-
turer’s safety regulations.
With contact pressure on the demolition
tool, the piston in the Street Hammer is
driven up to its starting position and the
hammer will begin cycling the tool up and
down. The stick/hammer end of the vehicle
may be raised a few inches (approximately
12 centimeters) from the ground so that
the weight of the carrier is exerted on the
demolition tool.
9.5 Advance From Outer Edge
(Refer to Figure 9-1.)
Start breaking large and hard rocks near
the outer edge.
Place the tool a short distance from the
edge of the material. If the rock does not
break away after thirty (30) seconds (maxi-
mum), the advance must either be reduced
or breaking restarted at a different point.
