OPERATING THE MACHINE
5-21
•
Do not operate breaker with the arm positioned verti-
cally. Excessive vibration to the arm cylinder will occur,
causing oil leakage.
•
Press the breaker so that the chisel (the axis) is posi-
tioned and thrusted perpendicular to the object.
•
Do not operate the breaker continuously longer than
one minute. Excessive chisel wear will result. If an
object could not be broken within one minute, apply
the chisel to other locations, less than one minute for
each location.
•
Raising the front part of the undercarriage by pressing
down the breaker may cause damage to the front at-
tachment. Although raising the front edge of the un-
dercarriage up to 150 mm (6 in) is tolerable, do not
practice this method more than necessary. Never
raise the front edge of the undercarriage higher than
150 mm (6 in) by pressing the breaker down.
