Breaker Operating Precautions
NOTE:
Hydraulic pressure and flow settings may need to be
changed. Refer to the Maintenance Section of this
manual for further information.
1.
Make sure to read and understand the breaker operator's
manual.
2.
Inspect all mechanical and hydraulic connections.
3.
Do not use the breaker as a hammer. See Figure 77.
4.
Do not drop breaker from extreme heights.
This can damage breaker or the excavator.
5.
Do not operate the breaker with the boom or arm cylinders
fully extended (bottomed out). See Figure 78.
Leave over 100 mm (4 in) of clearance between rod end of
cylinder and cylinder head. This will help prevent damage
to cylinders during breaker operation.
6.
Do not use the breaker if the hydraulic hoses vibrate
excessively. If excavator is operated under this condition,
structural and hydraulic components can be damaged.
7.
Do not allow the breaker body to go into water if not
equipped for underwater operation. The breaker seal can
be damaged and rust, foreign material or water can enter
the hydraulic system and cause damage. Only insert the
breaker tool into water. See Figure 80.
