EQUIPMENT PROTECTION & CARE
In addition to the Safety
Precautions in this manual,
observe the following for
equipment protection and
care.
NOTICE
• 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 ow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts with replacement parts recommended by Stanley
Hydraulic Tools. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow. Refer to Specications in this manual for correct ow rate.
Rapid failure of the internal seals may result.
• Always keep critical tool markings, such as warning stickers and tags legible.
• Do not force a small tool to do the job of a large tool.
• Keep tool bit sharp for maximum breaker performance. Make sure that tool bits are not chipped or
rounded on the striking end.
• Never operate a chipper without a tool bit or without holding it against the work surface. This puts
excessive strain on the retainer.
• 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.
