CONNECT HOSES 1 Wipe all hose couplers with a clean lint free cloth before making connections 2 Connect the hoses from the hydraulic power source to the tool fittings or quick disconnects It is a good practice to connect return hoses first and disconnect them last to minimize or avoid trapped pressure within the tool 3 Observe flow indicators stamped on hose couplers to ensure that fluid flow is in the proper direction The female coupler on the tool hose is the inlet coupler 4 Move the hydraulic circuit control valve to the ON position to operate the tool NOTE If uncoupled hoses are left in the sun pressure in crease within the hoses may make them difficult to connect When possible connect the free ends of the hoses together OPERATION PROCEDURES 1 Observe all safety precautions 2 Install the appropriate tool bit for the job 3 Place the bit firmly on the surface to be broken 4 Squeeze the trigger to start the breaker Adequate down pressure is very important When the tool bit breaks through the obstruction or becomes bound release the trigger and reposition the tool bit NOTE Partially depressing the trigger allows the tool to run at slow speed Slow speed operation permits easier starting of the tool bit into the work surface 5 To start break an opening hole in the center of the surface After making a hole break portions of the material into the original opening For best productivity t
