Tool Protection & Care

NOTICE

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 con- nection.

•The hydraulic circuit control valve must be in the “OFF” position when coupling or uncoupling hydrau- lic tools. Failure to do so may result in damage to the quick couplers and cause overheating of the hy- draulic 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 cir- cuit flow. 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 mini- mum working pressure rating of 2500 psi/172 bar.

•Do not exceed the rated flow (see Specifications) page in this manual for correct flow rate and model number. Rapid failure of the internal seals may re- sult.

•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.

•Never operate a hammer drill without a drill bit or without holding it against the work surface. To do so, places excessive strain on the hammer drill.

•Keep drill bits sharp for maximum tool performance. Make sure the drill bits are not chipped or rounded on the striking end.
