Do not attempt to operate defective equipment. Check that hoses 
and fittings are in good condition. 

 

l

 

Ensure maintenance procedures are carried out as specified. 

 

l

 

Do not attempt to operate this equipment on a greater hydraulic 
flow than that specified. 

 

   

l

 

Before using the equipment check for underground cables. Note: 
the breaker is not electrically insulated. 

 

l

 

Be aware of the dangers of collapse when working close to banks 
and in trenches. 

 

   

l

 

Never allow the point of a steel to rest against or be facing the 
direction of any part of the body. 

 

l

 

Fine jets of hydraulic oil can penetrate the skin. Check for leaks by 
holding a piece of cardboard near to the suspect area. If hydraulic 
oil does penetrate the skin or is ingested seek medical help 
immediately. 

 

   

l

 

Never attempt to dismantle the pressure accumulator. 

 

   

l

 

Always isolate hydraulic supply before making a disconnection or 
connection. 

 

   

l

 

Do not attempt to modify the equipment in any way. This could 
result in a 
dangerous product and will invalidate the warranty. 

 

l

 

Always comply with local and site safety regulations. 

 

   

l

 

When fitting and removing steels ensure the control valve at the 
hydraulic supply is in the 

OFF

 position. If no control valve is fitted 

the engine must be stopped. 

 

   

l

 

Never operate the breaker unless the steel is in contact with the 
work piece. 

 

 

l

 

Do not use steels that are worn at their shank. Blunted steels 
should be 
sharpened before use.
