OPERATING THE MACHINE
5-24
• Do not operate breaker with the arm positioned vertically.
Excessive vibration to the arm cylinder will occur, causing
oil leakage.
• Press the breaker so that the chisel (the axis) is positioned
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
attachment. Although raising the front edge of the
undercarriage 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.
