Hydraulic crusher operation tips…if equipped
Choose correct dimension and weight hydraulic crusher. Consult
with your dealer.
Operate excavator slowly to avoid overturning, and pay attention to
following items.
(1) In order to prevent damaging excavator, don‘t operate
hydraulic crusher when bucket cylinder fully extend or
retract (As figure 3.9.7).
(2) Don‘t swing upper structure to the side of machine to operate hydraulic crusher. In order to prevent
excavator overturning, it should carry out crushing only at frontage and rear of machine.
(3) Don‘t operate hydraulic breaker on slope. It should operate on horizontal ground.
(4) Don‘t use hydraulic crusher to haul debris.
(5) Hydraulic crusher operation will pollute hydraulic system and accelerate aging. It should replace
hydraulic oil filter core and hydraulic oil more frequently to avoid damaging hydraulic pump and
other hydraulic parts. The recommended replacement interval is referred to the ―Hydraulic breaker
operation tips‖.
(6) When transport excavator, remember to take out hydraulic crusher from the machine, and fit covers
or plugs on all hydraulic hoses.
