OPERATION & MAINTENANCE MANUAL SWE18UF
125
When retracting foreside work equipment, pay attention to not collide the hammer rod with the boom.
(7) Don’t operate the hammer breaker in the water.
(8) Don’t lift any objects with the hammer breaker. If
failure to do so, the excavator may tip and (or) the hammer
breaker may be damaged.
Don’t operate the hammer breaker after rotating the
upper-carriage to one side, because under this posture, the
excavator is very unstable.
9.3.4 Safe Operation of Hydraulic Hammer Breaker
a) Please stop operation when oil tube vibrates too
much. When high and low pressure oil tube of hammer
breaker vibrate excessively, that should be disassembled and
repaired, please contact with designated Sunward after-sale
service station.
b) Forbid empty hitting
Stop the striking on the moment once the rock is broken,
because continuous empty-hitting may not only damage the
drill rod and flat pins, and the load bearing mechanism.
When rod position is incorrect or when the drill rod is used
as a lever, empty hitting will happen. (the sound is different
if it’s empty hitting.)
c) Forbid to move rock
Forbid using side wall of hammer breaker to move rock,
because this is the main factor to damage the bolts of the
hammer breaker, drill rod, meanwhile, the boom and
mechanical boom will be damaged.
d) Do not use the drill rod as a crowbar
Bolts and drill rod also will be damaged when using the drill
rod as a crowbar.
