Hazardous Dust Warning

Warning: Demolition work may generate dust containing hazardous substances like asbestos, silica, or lead. Inhalation can cause serious injury, cancer, or death. Protect yourself and others. Understand the materials being cut and follow all applicable health and safety regulations, including proper disposal by a qualified person.

Tool Stickers & Tags

The tool is equipped with various stickers and tags providing critical safety information. Do not remove these tags.

Model Information Tag: Includes Model No. CH18, Flow: 7-9 GPM/26-34 LPM, Pressure: 2000 PSI/140 BAR, Name Tag (p/n 28852).

GPM Sticker: (p/n 03786)

DANGER Tags:

Tags attached to hoses provide crucial safety warnings:

Certified Non-Conductive Hose Tag:

DANGER:

• Failure to use non-conductive hose near electrical lines may result in death or serious injury. Ensure hose is maintained as non-conductive and tested for leakage.
• Hydraulic leaks or bursts can cause oil injection or severe injury. Do not exceed specified flow/pressure or hose working pressure. Check couplers daily for leaks; do not use hands to check.
• Do not lift or carry tool by hoses. Do not abuse hose; do not use kinked, torn, or damaged hose.
• Ensure hoses are properly connected (Pressure to "IN", Return to "OUT"). Reversing connections can cause severe injury.
• Do not connect open-center tools to closed-center systems.
• Keep bystanders clear of the work area.
• Wear hearing, eye, foot, hand, and head protection.
• All repair and service must be performed by authorized, trained personnel.

Conductive Hose Tag:

DANGER:

• Do not use this hose on or near electric lines; it is not certified non-conductive. Use may result in death or serious injury.
• Follow safety procedures for working near electric lines.
• Do not exceed hose working pressure or abuse hose. Improper use can result in burst or failure. Keep hose away from body.
• Handle hose carefully to avoid kinking, cutting, or contact with hot surfaces.
• Check hose for damage (cuts, cracks, leaks, bulges) and replace if damaged. Never use tape to mend.
• Store in a clean, dry area after each use.

IMPORTANT: Read operation manual and safety instructions before using. Use only approved parts and procedures. Tag to be removed only by tool operator.

Hose Types

Hydraulic hose working pressure must equal or exceed the system relief valve setting. Stanley Hydraulic Tools authorizes three types of hydraulic hose:

• Certified Non-conductive: Thermoplastic/synthetic rubber inner tube, synthetic fiber braid, weather-resistant cover. Labeled "certified non-conductive". Authorized for use near electrical conductors.
• Wire-braided (conductive): Synthetic rubber inner tube, single/double wire braid, weather-resistant cover. Conductive; must not be used near electrical conductors.
• Fabric-braided (not certified non-conductive): Thermoplastic/synthetic rubber inner tube, synthetic fiber braid, weather-resistant cover. Not certified non-conductive; must not be used near electrical conductors.

Hose Safety Tags

DANGER tags are attached to all Stanley Hydraulic Tools hose for safety. Do not remove them. Replace illegible tags immediately.

Hose Recommendations

The following chart shows recommended minimum hose diameters for various lengths and flow rates (GPM/LPM). These ensure minimum return line pressure for optimal tool performance.

All hydraulic hose must meet or exceed SAE J517 specifications and have a minimum working pressure rating equal to the maximum hydraulic system relief valve setting.

Operation

Pre-Operation Procedures

Preparation for Initial Use

The tool requires minimal unpacking. Inspect for shipping damage or debris.

Check Hydraulic Power Source

1. Verify flow: 7-9 GPM / 26-34 LPM at 1500-2000 PSI / 105-140 BAR.
2. Ensure relief valve is set to 2100-2250 PSI / 145-155 BAR minimum.
3. Confirm hydraulic circuit is for open-center (OC) operation.

Check Tool

1. Ensure all accessories are correctly installed to prevent damage or injury.
2. Check for leaks.
3. Ensure the tool is clean and all fittings/fasteners are tight.

Check Trigger Mechanism

Verify the trigger operates smoothly and moves freely between "ON" and "OFF" positions.

Install Tool Bit

The tool accepts standard 7/8 x 3-1/4 inch 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 tool bit orientation.

Connect Hoses

1. Wipe all hose couplers with a clean lint-free cloth before connecting.
2. Connect hoses from the power source to the tool couplers. Connect the return hose first and disconnect it last to minimize trapped pressure.
3. Observe flow indicators on couplers to ensure correct oil flow direction. The female coupler is the inlet.

Note: Hoses left in the sun may become difficult to connect. Connect free ends together when possible.

Operating Procedures

1. Observe all safety precautions.
2. Move the hydraulic circuit control valve to the "ON" position.
3. Place the tool bit firmly on the work surface.
4. Squeeze the trigger to start. Apply adequate down pressure.

Important Note

Do not use the CH18 underwater unless it is designated as an "Underwater" model.

Cold Weather Operation

If operating in cold weather, preheat hydraulic fluid. Use fluids at or above 50°F (10°C) / 400 ssu (82 cSt).

Storage

1. Disconnect the tool from the hydraulic power source.
2. Remove the tool bit and spray the retainer area with WD-40™.
3. Wipe clean and store in a clean, dry place.

Underwater Model Preventative Maintenance

After each use, flush movable parts exposed to water with a water-displacing oil (e.g., WD40). Remove remaining water and debris:

1. Turn tool upside down, spray oil into the retainer nose, cap, moving parts, and exposed piston area.
2. Spray oil into the On/Off valve trigger slot.
3. Dip or spray the entire tool.
4. Cycle the tool hydraulically several times before storing.

Troubleshooting

Use this chart to correct performance issues. Always verify hydraulic power source provides correct flow and pressure (7-9 GPM / 26-34 LPM at 1500-2000 PSI / 105-140 BAR) with oil temperature at least 80°F (27°C).

Tool Protection & Care

NOTICE: In addition to Safety Precautions, observe the following for equipment protection and care.

• Wipe all couplers clean before connection.
• Ensure the hydraulic circuit control valve is "OFF" when coupling/uncoupling. Failure to do so can damage couplers and overheat the system.
• Store the tool in a clean, dry place, 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 flow, as this can damage internal seals.
• Always replace hoses, couplings, and other parts with recommended Stanley Hydraulic Tools parts. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated flow specified in the manual; rapid seal failure may occur.
• Keep critical tool markings (warning stickers, 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.

Underwater Tools Depth Guideline

Underwater Models Only

CAUTION: Do not use hydraulic tools underwater unless designated as an "Underwater" model, as this will result in tool damage.

Underwater tool applications are categorized by tool type and operation method (diver or ROV).

Operation Overview

Diver Operation

• Percussive Tools (Breakers, Hammer Drills, Chipping Hammers): Max Depth: 500 ft. Limitations due to accumulator PSI max (increase 40 PSI for every 100 ft).
• Rotational Tools (Grinders, Saws, Chain Saws): Max Depth: 1000 ft. Refer to hose sizing guide.

ROV (Remotely Operated Vehicle) Operation

• Percussive Tools: Max Depth: 500 ft. Limitations due to accumulator PSI max (increase 40 PSI for every 100 ft).
• Rotational Tools: Max Depth: 1000 ft. Refer to hose sizing guide.

ROVs can reach lower depths, especially with depth-compensated power sources. Percussive tools have the same depth limitations regardless of operation method (ROV or diver).
