Hydraulic Breaker Operation
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 user's
manual.
2.
Inspect all mechanical and hydraulic connections.
3.
Do not use the breaker as a hammer. See Figure 72.
Do not drop breaker from extreme heights.
The breaker is relatively heavy and drops fast. Do not drop
breaker from extreme heights or damage to upper
structure may result.
4.
Do not operate the breaker with the boom or arm cylinders
fully extended (bottomed out). See Figure 73.
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.
5.
Do not use the breaker if the hydraulic hoses vibrate
excessively. See Figure 74. Check the breaker's hydraulic
accumulator (1) for damage and repair as required. If
excavator is operated under this condition, structural and
hydraulic components can be damaged.
