Hose Information
Hose Types
The hydraulic hose must have a working pressure rating equal to or higher than the system's relief valve setting. Three types of authorized hoses are:
- Certified non-conductive: Constructed with thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and a weather-resistant cover. Labeled "certified non-conductive" and is the only type authorized for use near electrical conductors.
- Wire-braided (conductive): Constructed with synthetic rubber inner tube, single or double wire braid reinforcement, and a weather-resistant synthetic rubber cover. This hose is conductive and must not be used near electrical conductors.
- Fabric-braided (not certified non-conductive): Constructed with thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and a weather-resistant cover. Not certified non-conductive and must not be used near electrical conductors.
Hose Safety Tags: DANGER tags are attached to all STANLEY hoses for safety. Do not remove these tags. Replace illegible tags immediately.

Operation
Preparation Procedures
- Unpacking and Inspection: The tool requires no special unpacking or assembly. Inspect for shipping damage and debris.
- Check Hydraulic Power Source:
- Verify flow of 7-9 GPM (26-34 LPM) and pressure of 1500-2000 psi (105-140 bar) using a calibrated flowmeter and pressure gauge.
- Ensure the power source has a relief valve set to open at 2100-2250 psi (145-155 bar).
- Confirm the hydraulic circuit matches the tool for open-center (OC) operation.
- Check Tool:
- Ensure all accessories are correctly installed.
- Check for leaks.
- Verify the tool is clean and all fittings/fasteners are tight.
- Check Trigger Mechanism: Ensure the trigger operates smoothly between "ON" and "OFF" positions.
Install Tool Bit
The tool accepts standard 0.580 in hex x 2-1/2 inch long hex shank tool bits. To install: Push in the retainer, insert the tool bit, and move the retainer back to the locked position. Note the orientation of the bit.
Connect Hoses
- Wipe all hose couplers with a clean, lint-free cloth before connecting.
- Connect hoses from the hydraulic power source to the tool couplers. Connect the return hose first and disconnect it last to minimize trapped pressure.
- Observe flow indicators on couplers to ensure correct oil flow direction. The female coupler is the inlet.
Note: Pressure in uncoupled hoses exposed to sun may make them difficult to connect. Connect free ends of operating hoses together when possible.
Operating Procedures
- Observe all safety precautions.
- Move the hydraulic circuit control valve to the "ON" position.
- Place the tool bit firmly on the surface to be worked on.
- Squeeze the trigger to start the tool. Apply adequate down pressure.
Cold Weather Operation
If operating in cold weather, preheat the hydraulic fluid. Fluid temperature should be at or above 50°F (10°C) (400 ssu/82 centistokes) before use.
Storage
- Disconnect the tool from the hydraulic power source.
- Remove the tool bit and spray the retainer area (inside and out) with WD-40™.
- Wipe clean and store in a clean, dry place.
Underwater Model Preventative Maintenance
For underwater models, flush movable parts exposed to water with a water-displacing oil (e.g., WD-40™) after each use. Remove any remaining water and debris:
- Turn the tool upside down (without the bit) and spray oil into the retainer nose, retainer cap, and moving parts. Also spray the piston area to displace water.
- Spray oil into the On/Off valve trigger slot.
- Dip or spray the entire tool.
- Cycle the tool hydraulically several times before storing.
Troubleshooting
Use this chart to diagnose and correct performance issues. Always verify hydraulic power source flow and pressure.
| PROBLEM | CAUSE | SOLUTION |
|---|---|---|
| Tool does not run. | Power unit not functioning. | Check power unit for proper flow and pressure (7-9 GPM/26-34 LPM, 1500-2000 psi/105-140 bar). |
| Couplers or hoses blocked. | Remove restriction. | |
| Pressure and return line hoses reversed at ports. | Ensure hoses are connected to their proper ports. | |
| Mechanical failure of piston or internal parts. | Have inspected and repaired by an authorized dealer. | |
| Tool does not hit effectively. | Power unit not functioning. | Check power unit for proper flow and pressure (7-9 GPM/26-34 LPM, 1500-2000 psi/105-140 bar). |
| Couplers or hoses blocked. | Remove restriction. | |
| Fluid too hot (above 140°F/60°C). | Provide cooler to maintain proper fluid temperature. | |
| Incorrect tool bit. | Ensure tool bit meets specifications. | |
| Tool operates slow. | Low oil flow from power unit. | Check power source for proper flow. |
| High back-pressure. | Check hydraulic system for excessive back-pressure and correct as required. |
Tool Protection & Care
Observe the following for equipment protection and care:
- Ensure all couplers are wiped clean before connection.
- Keep the hydraulic circuit control valve in the "OFF" position when coupling or uncoupling tools. Failure to do so may damage couplers or overheat the hydraulic system.
- Always store the tool in a clean, dry space, safe from damage or pilferage.
- Connect the PRESSURE hose (male quick disconnect) to the "IN" port and the RETURN hose (female quick disconnect) to the opposite port. Do not reverse circuit flow, as this can damage internal seals.
- Always replace hoses, couplings, and other parts with recommended STANLEY parts. Supply hoses must have a minimum working pressure rating of 2500 psi (172 bar).
- Do not exceed the rated flow; rapid failure of internal seals may result. Refer to "SPECIFICATIONS" on page 13 for correct flow rate and model number.
- Always keep critical tool markings, such as warning stickers and tags, legible.
- Tool repair should only be performed by experienced personnel.
- Ensure recommended relief valves are installed in the pressure side of the system.
- Do not use the tool for unintended applications.
