Stanley Black & Decker GR30 Manuel D’Utilisation

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.
