Position the hydraulic breaker vertically towards solid
bedrock or similar to adjust the pressure using a
pressure gauge.
Water flushing
The hydraulic breaker is prepared for water flushing,
this function is to bind the dust when performing
demolition operations.
When connecting water flushing the plug in the front
of the breaker must be exchanged with a water
nozzle. See the Spare parts list for ordering a new
water nozzle.
Use a ¼ in. hydraulic hose with a JIC connection as
a proper water hose. Contact your nearest authorised
workshop for further instructions.
NOTICE It is recommended to use water flushing
to reduce the wear on the hydraulic breaker during
tunnel and dust-intensive applications.
