Maintenance
Before use:-
1.
Check hose whips for damage or exposed wire braid and replace as necessary.
2.
Check the tightness of all fasteners.
3.
Check the trigger safety catch and trigger moves freely.
4.
Remove oil filler plug (1) and make sure the grinder body has the correct amount of lubricating
oil (15W/40). Correct oil level is achieved when the grinder is held horizontal with the spindle
pointing down. Oil should then be level with bottom of the filler hole.
5.
Check the condition of the disc and replace as necessary.
After use:-
1.
Ensure any faults with the grinder are reported and do not use it until rectified.
2.
Wash the grinder off with clean water and work a light oil to the moving parts e.g. valve spool,
trigger and safety catch.
3.
Store away in a clean environment.
Operation
1.
Make sure that the power pack has a maximum output flow of 40 Litres Per Minute and that the
maximum system pressure is no more than 155 Bar (2250 psi).
2.
Ensure the hydraulic circuit is of the open centre (OC) type.
3.
Wipe the flat face couplings with a clean cloth.
4.
Connect the return hose first to the power pack and then the pressure hose. When
disconnecting, uncouple the pressure hose first and the return hose last so as to minimize any
pressure being trapped in the grinder. If the couplings will not connect due to pressure within
the grinder, slowly loosen off one of the couplings allowing some oil to leak out. Re-tighten the
coupling and connect to the power pack.
5.
Start the power pack and move the ‘ON/OFF’ lever to the ‘ON’ position.
6.
Hold the grinder with both hands i.e. one hand grasping the side handle and the other hand
around the trigger.
7.
Operate the trigger and ensure the disc rotation is correct (CW if viewed from above) and that
there are no leaks.
8.
Do not start the grinder with the disc in contact with the work surface.
Note:- For operator comfort and better control over the Grinder when used in awkward
places, the Grinder head can be rotated in relation to the trigger by loosening the
cap screw (8) and rotating the head to the desired position then retighten the cap screw.
WARNING:- Disconnect the Grinder from the power source before carrying out
this procedure.
