OPERATION
PREOPERATION PROCEDURES
CHECK POWER SOURCE
1. Using a calibrated ow meter and pres sure gauge,
make sure the hydraulic power source develops a
ow of 7–12 gpm/26–45 Ipm at 1000–2000 psi/70–
140 bar.
2. Make certain that the power source is equipped with
a relief valve set to open at 2100 psi/145 bar maximum.
3. Make certain that the power source re turn pressure
does not exceed 250 psi/17 bar.
4. Make sure the trash pump inlet is clear of debris.
Remove any obstruction before operating. Refer to
PUMP CLEANING PROCEDURES.
CONNECT HOSES
1. Wipe all hose couplers with a clean lint free cloth
before making connections.
2. Connect the hoses from the hydraulic power source
to the couplers on the trash pump or trash pump
hoses. It is a good practice to connect return hose
rst and disconnect it last to minimize or avoid
trapped pressure within the trash pump motor.
NOTE:
If uncoupled hoses are left in the sun, pressure in-
crease inside the hoses might make them difcult to
connect. Whenever possible, connect the free ends
of the hoses together.
3. Observe the arrow on the couplers to ensure that the
ow is in the proper direc tion. The female coupler on
the trash pump is the inlet (pressure) coupler.
PUMP OPERATION
1. Observe all safety precautions.
NOTE:
The SM50 is not designed for use with a suction
pipe inlet. The diameter of the suction screen at the
bottom of the pump provides maximum pump ef-
ciency. Reducing the size of this inlet will greatly
reduce pump performance.
2. Connect a hose tted with a 3 inch/76.2 mm female
camlock coupler to the pump outlet tting. Make
sure the tting is securely tightened. For best perfor-
mance, keep the hose as short as possible and lay
it out to avoid sharp bends or kinks.
3. Lower the pump into the liquid to be pumped. Locate
the outlet end of the discharge hose to disperse the
liquid as required. Remove any kinks from the hose
to assure maximum water ow.
Never point the hose at bystanders.
4.
Turn on the hydraulic power source. Watch for solids in the liquid being pumped. If solids are excessive, the discharge ow might decrease. If this happens, stop the pump and check for the cause of the
problem.
Under some conditions, the liquid being pumped
might be slowed enough so It can no longer push
particles in the liquid. If this happens, particles can
accumulate in the hose and backup the pumping
chamber, causing further restriction. The impeller then acts as a “grinding wheel which causes
acceler ated pump wear. Reduced liquid ow can be
caused by the following:
• The pump sinks into solids at the bottom of the
hole.
• The end of the outlet hose is too high, causing
an excessive lift height for the column of liquid
being pushed by the trash pump. This slows the
ow of liquid to a level where it can no longer
carry solids out the end of the hose.
• The ow and pressure of hydraulic uid to the
pump is too low, which re duces impeller speed.
A 20% de crease in hydraulic uid ow can reduce pump performance by 50%. When operat-
ing at reduced hydraulic ow and pressure, the
end of the outlet hose should not be more than
30 ft/9 m above the liquid.
5. When pumping is complete, set the hy draulic control
valve to the “OFF” posi tion. Lift the pump from the
work area.
COLD WEATHER OPERATION
If the trash pump is to be used during cold weather,
preheat the hydraulic uid at low power source speed.
When using the nor mally recommended uids, uid
should be at or above 50 °F/10 °C (400 ssu/82 centistokes) before use.
Damage to the hydraulic system or pump motor seals
can result from use with uid that is too viscous or thick.

OPERATION
CLEANING THE PUMPING
CHAMBER
Debris such as weeds, sand and other solids may become trapped in the water hose and pumping chamber.
This can reduce pump performance. It is important that
the pumping chamber be kept clean at all times. The
chamber can be cleaned as follows:
1. Remove motor and impeller by removing the two
M12 × 1.75 Hex Head capscrews.
2. Remove all debris from the pump screen.
3. Thoroughly clean the volute and impeller. Do not
remove the impeller unless necessary for repair or
replacement or to remove trapped debris.
4. Assemble the motor and impeller to the volute.
Clean the capscrews and lubricate the threads with
underwater grease before installation.
5. Remove all debris from the hose. Otherwise, solids
will backll the pump.

NOTICE
TOOL PROTECTION & CARE
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 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 couples 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 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 minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow (see Specications) in
this manual for correct ow rate and model number.
Rapid failure of the internal seals may result.
• Always keep critical tool markings, such as warning
stickers and tags legible.
• Do not use the tool for applications it was not designed for.
• 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.

TROUBLESHOOTING
If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.
When diagnosing faults in operation, always make sure the hydraulic power source is supplying the correct hydrau-
lic ow and pressure as listed in the table. Use a owmeter know to be accurate. Check the ow with the hydraulic
uid temperature at least 80 °F/27 °C.

UNDERWATER TOOLS DEPTH GUIDELINE
UNDERWATER MODELS ONLY
CAUTION
DO NOT USE HYDRAULIC TOOLS UNDER-
WATER THAT ARE NOT DESIGNATED AS
AN “UNDERWATER” MODEL, OR THIS
WILL RESULT IN DAMAGE TO THE TOOL.
For underwater hydraulic tools the applications are
broken down into four quadrants depending on
type of tool and method of operation.
The types of tools are percussive and rotational,
each with different characteristics allowing for different depth operation. With percussive tools, the
nitrogen accumulator PSI must counter the increase in ambient pressure found at lower depths.
Since there is a maximum PSI for percussive tools
they are limited to certain depths. Rotational tools
do not have accumulators and thus capable of
deeper depths.

The methods are broken into diver operated or
remote operated vehicle (ROV). ROV's can reach
lower depths and with an on-board hydraulic
power source that is depth compensated, can
operate hydraulic tools at depths of thousands of
feet. ROV operation is still limited to the tool, for
example a percussive tool has the same depth
limitation whether ROV or diver operated.
