• 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 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 mini-
mum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow and pressure. See
Specications in this manual for correct ow rate
and pressure rating. Rapid failure of the internal
seals may result.
• 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.
