TOOL PROTECTION & 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 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 (see Specications)
page in this manual for correct ow rate and model
number. Rapid failure of the internal seals may re-
sult.
NOTICE
In addition to the Safety Precautions found in
this manual, observe the following for equipment
protection and care.
• 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.
