OPERATION

PREPARATION PROCEDURES
Each unit, as shipped, has no special unpacking or assembly requirements prior to usage. Inspection to assure the unit was not damaged in shipping and does not contain packing debris is all that is required. After installation of a grinding wheel a unit may be put to use.

CHECK HYDRAULIC POWER SOURCE

1. Using a calibrated flow meter and pressure gauge, check that the hydraulic power source develops a flow of 7-10 GPM/26-38 LPM at 1500-2000 psi/105-140 bar.
2. Make certain the hydraulic power source is equipped with a relief valve set to open at 2100-2250 psi/145-155 bar minimum.
3. Check that the hydraulic circuit matches the tool for open-center (OC) or closed-center (CC) operation.

CHECK TOOL

1. 1. Make sure all tool accessories are correctly installed. Failure to install tool accessories properly can result in damage to the tool or personal injury.
   2. There should be no signs of leaks.
   3. The tool should be clean, with all fittings and fasteners tight.

CHECK TRIGGER MECHANISM

• Check that the trigger operates smoothly and is free to travel between the “ON” and “OFF” positions.

CHECK GUARD ASSEMBLY

1. Inspect the wheel guard assembly for cracks and other structural damage.

INSTALLING AND REMOVING GRINDING WHEELS
Read and become familiar with the sections in this manual on safety precautions, tool stickers and tags, hydraulic hose requirements, hydraulic requirements, and pre-operation procedures before using this product.

Never over-tighten the grinding wheel by impacting the wrench with a mallet or hammer. Sufficient torque is attained by hand-tightening the wheel with a strap wrench or for wheels secured with caps crews, hand tightening with a socket wrench while depressing the push lock.

Note: Use 6-inch diameter up to 3-inch thick (Type 6 for USA/Type 36 for CE) grinding wheels with a 5/8-11 threaded arbor hole. Only use grinding wheels which comply with ANSI B7.5/ISO 525, 603.

• Depress the push lock (6) and screw the grinding wheel onto the main shaft (13) and tighten using a strap wrench.
• Adjust guard to desired height.

CONNECT HOSES

• Wipe all hose couplers with a clean lint-free cloth before making connections.
• Connect the hoses from the hydraulic power source to the hose couplers on the grinder. It is a good practice to connect the return hose first and disconnect it last to minimize or avoid trapped pressure within the grinder motor.
• Observe flow indicators stamped on hose couplers to be sure that oil will flow in the proper direction. The female coupler is the inlet coupler.

Note: The pressure increase in uncoupled hoses left in the sun may result in making them difficult to connect. When possible, connect the free ends of operating hoses together.

OPERATING PROCEDURES

• Observe all safety precautions.
• Always start the grinder with the grinding wheel away from the work surface.
• Move the hydraulic circuit control valve to the “ON” position.
• Disengage the safety thumb latch (42) and squeeze the trigger momentarily. If the grinder does not operate, the hoses might be reversed. Verify correct connection of the hoses before continuing.
• Start the grinder and move the grinding wheel or cone to the work surface.
• Grind a small amount of material at a time.
• As the grinding stone wears, adjust guard height by depressing the guard latch (26) and rotate the guard to lower or raise height.

COLD WEATHER OPERATION
If the grinder is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluids, fluid temperature should be at or above 50° F/10° C (400 ssu/82 centistokes) before use.

TROUBLESHOOTING

If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem. When diagnosing faults in operation of the grinder, always check that the hydraulic power source is supplying the correct hydraulic flow and pressure to the grinder as listed in the table. Use a flowmeter known to be accurate. Check the flow with the hydraulic oil temperature at least 80°F/27°C.

TOOL PROTECTION & CARE

In addition to the safety precautions found in this manual, observe the following for equipment protection and care.

• Make sure all couplers are wiped clean before connection.
• The hydraulic circuit control valve must be in the “OFF” position when coupling or uncoupling hydraulic tools. Failure to do so may result in damage to the quick couplers and cause overheating of the hydraulic system.
• Always store the tool in a clean dry space, safe from damage or pilferage.
• Make sure the circuit PRESSURE hose (with male quick disconnect) is connected to the “IN” port. The circuit RETURN hose (with female quick disconnect) is connected to the opposite port. Do not reverse circuit flow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts with replacement parts recommended by STANLEY. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated flow (see “SPECIFICATIONS” on page 14) in this manual for correct flow rate and model number. Rapid failure of the internal seals may result.
• Always keep critical tool markings, such as warning stickers and tags, legible.
• Tool repair should be performed by experienced personnel only.
• Make certain that the recommended relief valves are installed in the pressure side of the system.
• Do not use the tool for applications for which it was not intended.
