Tool Connecting Procedures
1. Stop the engine before connecting the tool and or hoses to the OFF power unit, and when switching
hoses or tools.
2. Turn the hydraulic on/off valve to the off position before starting the engine.
Make sure all hoses are connected for correct flow direction to and from the tool being used.
When routing hose in the work area, position them where personnel will not be at risk of tripping over
them where vehicles can run over the hoses. Do not lay hose over sharp objects.
Pressurized fluid escaping from a damaged hose can penetrate the
skin and be injected in the body causing injury or death.
Do not pull on hoses to drag the power unit or tool
.
Connecting Hoses
1. Wipe quick couplers with a clean lint free cloth before connecting them.
2. Depressurize the system.
3. Allow system and hydraulic fluid to cool if too hot to handle.
4. Securely connect the return (tank “R”) hose from the power source to the tool.
5. Securely connect the supply (pressure “P”) hose from the power source to the tool.
It is recommended that you connect the return hoses first and disconnect last to minimize or avoid
trapping pressure within the tool.
When connecting the quick couplers, the flow should run from male coupler to the female coupler.
The female coupler on the tool is the inlet. Quick couplers are marked with a flow direction arrow.
Pressurized fluid escaping from a damaged hose can penetrate the
skin and be injected in the body causing injury or death.
Do not pull on hoses to drag the power unit or tool
.
Note
: When possible, connect the free ends of uncoupled hoses to prevent build up in the hoses. The
sun can also increase pressure in the hoses and make connecting them difficult.
1. Grip the handles firmly with both hands.
2. Pull down with thumb on the safety lock and pull the trigger to the handle to start the grinder.
3. When starting the tool, hold it off from all surfaces.
4. Start grinding with the tool running.
5. When finished, release trigger and allow stone to stop turning and make sure trigger is in the locked
position before placing the tool on any surface.
