StartSelect System
AutoStart/AutoStop
The StartSelect System enables you set the start
and switch-off behaviour of the hydraulic breaker to
the relevant conditions.
The hydraulic breaker is factory-set to the “AutoStart”
setting (= easy start), i.e. the breaker starts in its
working position after switching on without exerting
pressure on the working tool.
This start behaviour enables greater productivity and
easier handling when working on unstable surfaces,
e.g.:
● block holing in broken ground or debris
● working in horizontal and/or overhead positions
● reducing light concrete structures
You can integrate the StartSelect valve the other way
around to quickly adjust the hydraulic breaker to the
“AutoStop” (= automatic switch-off) integration
setting.
The hydraulic breaker is switched on while exerting
pressure on the working tool in the “AutoStop”
(= automatic switch-off) setting. However it will switch
off automatically during operation when the
percussion piston no longer hits the working tool.
Idling strokes are avoided this way.
This setting is an advantage when using the breaker
on a stable surface:
● trenching
● slope construction in quarry operations
● digging foundations in rocks
● reducing large concrete structures
Switching between AutoStart/AutoStop
♦
Place the hydraulic breaker on timber support
blocks.
WARNING Unexpected movement
Sudden movements of the carrier may cause serious
injury.
► Secure the carrier such that it cannot move
unexpectedly.
► Observe the carrier manufacturer’s instructions.
WARNING Jets of hot hydraulic oil can
escape
The hydraulic system is under high pressure. If
hydraulic connections come loose or are
disconnected, hydraulic oil will squirt out under high
pressure. Hydraulic lines may spring a leak or burst.
Hydraulic oil squirting out can lead to serious injury.
► Depressurise the hydraulic system before
connecting or disconnecting the hydraulic circuits
of the hydraulic attachment (see chapter
Depressurising the hydraulic system).
♦
Close all shut-off valves in the system at the boom
if no quick couplings are used.
♦
Disconnect the hoses to and from the hydraulic
breaker on the boom side.
♦
Plug up all open hose ends.
