SAFETY INFORMATION
SPECIAL NOTE: TO AVOID PERSONAL INJURY, BEFORE OPERATING AN
ELECTRICALLY POWERED LI’L SUCKER, THE CUSTOMER MUST CONNECT THE 3WIRE ELECTRICAL CORD TO A SUITABLE POWER SUPPLY THAT IS ALSO
PROPERLY GROUNDED. THE GREEN WIRE IN THE ELECTRICAL BOX OF THE LI’L
SUCKER IS THE GROUND WIRE. THE CUSTOMER’S GROUND SOURCE MUST BE IN
ACCORDANCE WITH ARTICLE 250 OF THE NATIONAL ELECTRIC CODE (NEC) OR
OTHER SUITABLE REGULATION IF IN A COUNTRY OTHER THAN THE UNITED
STATES OF AMERICA.
1.
To avoid possible injury, before operating this Li’l Sucker, read this manual for full operating
instructions.
2.
Always block the wheels of the Li’l Sucker to prevent unintentional rolling. Accidental rolling
on a sloped floor, if bumped, could cause injury or property damage.
3.
Wear eye goggles to protect your eyes from splashing liquids. This is important, even when
you know the fluids themselves are not caustic or otherwise harmful. Metal particles
suspended in the liquid could still cause serious eye injury.
4.
Check hose, nozzle, cleaning tool, and hose cap connections for leaks. To minimize chances of
spilling, handle cleaning tools and hoses carefully during operation, and replace hoses before
deterioration results in leaks.
5.
Immediately clean up any spilled coolant to avoid slippery floors and dangerous falls.
6.
If it is necessary to use the Li’l Sucker in an aisle or other traffic area, position it to minimize
the likelihood of being struck by trucks, forklifts or other equipment in transit. Exercise a
reasonable lookout for such hazards during operation.
7.
Whenever removing or reseating the filter basket (maximum chip/sludge capacity is
approximately 200 to 300 pounds, or 90 to 136 kg), keep hands and fingers out from under the
basket lip. CAUTION: All components used to lift the basket (steel cable, hooks, crane, etc.)
must have a minimum capacity of 1,000 pounds (455 kg).
8.
Keep clear from beneath the basket when trying to empty its contents, or if necessary, to pull
out the polypropylene liner. Use tools of appropriate strength and length to let you perform
these operations safely.
3
9.
Frequently check the basket’s hoisting rings for signs of rust. If the rings are heavily corroded,
replace the basket with a new one.
10.
Be sure the suction inlet ball valve (S1) is fully closed before operating the Li’l Sucker in the
discharge mode. The tank is pressurized in this mode, sometimes to as much as four to five
PSIG.
11.
The electric motor on your cleaner is designed to be used only with the electric supply
specified on the Specifications Page of this manual, and on the motor enclosure. Use with any
other type of connection or power source may damage the equipment or cause personal injury.
12.
Do NOT use this unit for solvents, flammable cleaners (low flash point) or other volatile
liquids. Use it only for water-soluble coolants and for cutting or grinding oils.
13.
“Push-around” units (swivel casters at both ends) are NOT designed for towing. If they must
be moved long distances within a plant; pick up the unit with a forklift truck.
14.
This equipment is to be operated and maintained by authorized personnel only.
15.
MAGNESIUM CHIPS OR DISSIMILAR METALS. In the presence of water,
magnesium can release hydrogen gas, which is highly flammable and, in the proper
proportions with air, can be explosive. When a Li’l Sucker is used on a metalworking fluid
application generating magnesium chips, certain precautions must be taken to ensure that any
hydrogen gas is dissipated into the atmosphere and to make sure the hydrogen does not
accumulate in the Li’l Sucker. This is accomplished by promptly removing any magnesium
chips from the Li’l Sucker basket. In addition, a maintenance schedule should be established
by the customer that would eliminate buildup of sludge in the bottom of the Li’l Sucker.
Finally, the unit should be stored with the basket empty of chips, the chip basket lid removed,
the coolant discharge nozzle removed and hoses open to the atmosphere. Taking these
precautions will minimize the risk of hydrogen gas generation and accumulation. On an
application where dissimilar metals are machined, there is a chance for spontaneous
combustion to occur. Typically, metalworking facilities that machine various metals are aware
of this and may have experienced problems in chip hoppers due to the presence of two of more
metals, water, and tramp oil. The precautions mentioned in this paragraph will minimize or
eliminate the potential for spontaneous combustion.
16.
The Li’l Sucker is to be adjusted and/or repaired only by qualified service personnel. If these
personnel need more information than is provided in this manual, they should Eriez Hydroflow .

LI’L SUCKER
SAFETY FEATURES
PRESSURIZATION SAFETY ISSUES
Your Li’l Sucker is designed to operate under pressure when discharging fluids. The optimal safe
operating pressure should always be less than 7 PSI and your unit was set at below this level at the
factory. Your unit should never be operated at pressures exceeding factory settings. Tanks or vessels,
which are pressurized beyond this pressure, require ASME certification as “Pressure Vessels” and the
Li’l Sucker has not been certified for such high-pressure operation. Operating a Li’l Sucker at
pressures above this creates a serious risk of injury to workers and damage to property.
IMPORTANT SAFETY WARNING!
ALTERING OR MODIFYING SAFETY REGULATING FEATURES TO DEFEAT THEM
MAY RESULT IN THE TANK BECOMING OVER PRESSURIZED. OVER
PRESSURIZATION MAY CAUSE THE EXPLOSIVE RUPTURE OF THE TANK
RESULTING IN SERIOUS INJURY OR DEATH TO WORKERS AND DAMAGE TO
PROPERTY. MODIFYING OR INTENTIONALLY DEFEATING THESE IMPORTANT
SAFETY FEATURES WILL CONSTITUTE THE INTENTIONAL MISUSE OF THE
EQUIPMENT VOIDING ALL WARRANTIES.
STANDARD SAFETY FEATURES
Although your Li’l Sucker is an inherently safe machine, it could pose the potential for hand and
finger injury when the operator has to remove the filter basket from the unit and empty it of chips and
sludge. For this reason, Eriez Hydroflow has two safety features on this machine:

The filter basket automatically centers itself within the unit’s basket support as it is being hoisted
out of the machine. This eliminates the need for the operator to physically guide the heavy, chipladen basket as it is being raised. This significantly reduces the opportunity for the operator to
receive hand injury.

The unique tipping-basket design enables the operator to empty the filter basket (the basket can
hold up to 200 to 300 pounds, or 90 to 136 kg of chips) without the need for special tools. The
basket is removed from the unit, positioned over a chip hopper or similar device, and then slowly
lowered until in contact with the materials already in the hopper. The basket is then lowered
further while tipping the basket with the handle on the bottom of the basket.
5
CONVENIENCE FEATURES

Low rolling resistance, high maneuverability design: Li’l Suckers feature high impact, fiber
reinforced, hard plastic casters and wheels for low rolling resistance, whether the unit is empty or
full. The standard wheel configuration places the main wheels in the unit’s middle and swivel
casters on each end for high maneuverability. A Li’l Sucker pivots in twice its own length.

Swing-bolt basket lids make lid removal and replacement easy and fast.

Our lightweight, gasoline pump-type nozzle makes filling the machine with clean coolant easier.

“Smooth 90°” filter basket suction inlet virtually eliminates suction hose “chip jams”.

The electronic float overfill protection assembly eliminates motor damage and coolant spills by
shutting off the motor when the tank is full.

OPERATION
1.
Before operating this equipment for the first time, and periodically thereafter, review the
SAFETY INFORMATION beginning on page three of this manual.
2.
Suction vacuum and discharge pressure are applied independently in this unit by moving a
hose attached to the tank to either the suction fitting or the discharge fitting as required.
3.
Connect the Li’l Sucker to the electrical supply specified on the electrical box housing the
motor. For North America, this is 120 VAC, single phase, 60 Hz.
4.
Suction Operation:
a.
Connect the black hose to the suction port on the electrical box containing the motor
assembly.
b.
Open suction inlet valve (S1) fully with suction hose properly attached. MAKE SURE
THAT THIS VALVE IS EITHER FULLY OPEN OR FULLY CLOSED AT ALL
TIMES. FAILURE TO DO SO WILL ALLOW PARTICULATE MATTER TO
ENTER THE VALVE SEAT, WHICH COULD SEIZE THE VALVE.
c.
Make sure that the discharge hose is connected, and that the discharge nozzle is attached
and closed.
d.
Turn on the Li’l Sucker by placing the “on-off-on” switch into the “SUCTION ON”
position. NOTE: THE FLOAT SWITCH WILL ONLY WORK WHEN SUCTION ON
IS SELECTED, IT IS NOT WIRED INTO THE DISCHARGE ON CIRCUIT
e.
Vacuum coolant, chips, and sludge from the machine sump.
f.
An electric float located in the tank will rise with the rising liquid level in the tank and
shut off the motor when the tank is full. When this occurs, the Li’l Sucker will stop
sucking.
g.
When you are done vacuuming coolant and chips, turn off the Li’l Sucker.
5.
Discharge Operation: To return filtered, chip-free coolant to the machine, to wash down the
machine, or to discharge coolant into your recycling or disposal system:
a.
Close the suction inlet valve (S1) completely.
b.
Move the black hose from the suction inlet (on the electrical box housing the motor
assembly) to the discharge fitting.
c.
Turn the unit on by placing the on-off-on switch to the “DISCHARGE ON” position.
d.
Depress the handle of the discharge nozzle to begin the fluid flow.
e.
When discharging operation is complete, turn the unit off.
9
f.
6.
The Li’l Sucker will discharge nearly all the fluid in the bottom of the tank
compartment. This is unimportant if the unit remains in reasonably frequent use on a
single coolant. If different coolants are used, or the unit will be stored for some time,
remove the discharge hose, hose fitting on the bottom of the unit, and drain the unit
completely.
To empty the Filter Basket:
a.
b.
c.
d.
e.
f.
g.
Remove lid.
Attach an OSHA approved lifting device to basket rings. CAUTION: All components
used to lift the basket (steel cable, hooks, hoist, crane, etc.) must have a minimum
capacity of 1,000 pounds or 455 kg.
To avoid the basket binding in the tower during removal, position the lifting power
source (e.g. crane) directly over the center of the basket.
Hoist the basket. Keep hands and fingers clear. If the basket is not exiting the center of
the tower, return (lower) basket to the Li’l Sucker tower. Reposition the lifting device so
that the basket exits the center of the tower.
DO NOT TOUCH BASKET DURING REMOVAL.
Position the basket over the waste receptacle and lower until in contact with material in
waste receptacle.
Tip the basket on its side and over to empty. The handle on the bottom of the chip basket
can be used to assist with this effort.
7.
Check the filter sleeve. If it is badly soiled or clogged, turn it inside out and wash it with a nonsolvent cleaning solution. Replace filter when necessary.
8.
Inspect the basket hoisting rings for signs of rust. Replace the basket assembly with a new one
if the rings are heavily corroded.
9.
Keeping hands and fingers from under the basket lip, reseat the basket in the tank and fasten
down the tank lid.

10
OPERATING TIPS
The Li’l Suckers have been designed to make the job of proper machine tool coolant sump cleaning as
easy as possible for the operator of the Li’l Sucker. They have the power necessary for true, highperformance sump cleaning; they will vacuum from the sump anything that will pass through its two
inch diameter suction hose, and it will suck up water miscible products (coolants, cleaners) at nearly
85 gallons per minute, or 320 liters per minute. At the same time, all Li’l Suckers are designed with
operator safety, ease of operation, and maintenance as foremost considerations.
Although the Li’l Sucker is designed for operator safety, before using the Li’l Sucker for the first time
(and periodically thereafter for a review) read the section of this Operator’s Manual entitled “Safety
Information”, pages 3-4.
PROPER MACHINE CLEANING PROCEDURE
Your Master Chemical District Manager has been specially trained in machine cleaning techniques
and is available to help point out potential problem areas where hidden sludge deposits can accumulate
in your machines. Feel free to call him for assistance.
OPERATING EFFICIENCY TIPS
Here are some tips to improve the operating efficiency of your Li’l Sucker:
•
Follow the Li’l Sucker’s maintenance schedule carefully. Preventive maintenance is far less
expensive than major repairs.
•
Clean your Li’l Sucker about once a month, or whenever sludge or fines become noticeable in
the bottom of the tank.
•
Rinse the unit with plain water and drain it completely by removing the drain plug/discharge
hose whenever changing from one brand or type of coolant to another. There can be
compatibility problems created by mixing some products, so avoid contamination. (Remember
to replace the plug.)
•
It is better to have one Li’l Sucker for use with water-soluble coolants and another for use with
cutting oils. If you must use one unit for both, the Li’l Sucker must be thoroughly cleaned
when switching products. If possible, purchase a filter basket and a set of hoses for each
product. (The Li’l Sucker tank is not too hard to clean, but the hoses and filter basket are.)
Organize your machine-pumping schedule so that during one week, you are pumping machines
running water solubles and the next week you are pumping machines running cutting oils. This
minimizes cleaning the Li’l Sucker.
11
•
When vacuuming out machines put the cleaning tool on the bottom of the sump, and remove
fluid and chips together.
•
In the event you experience a stoppage in the unit’s suction hose, the suction hose’s cleaning
tool should be held and pointed into the machine sump (NOTE: DO NOT POINT IT AT
PERSONNEL) and the Li’l Sucker started in the discharge mode. Usually, the discharge
pressure generated is sufficient to clear the stoppage by blowing the obstruction back into the
machine sump. If the stoppage is not cleared in this manner, remove the hose from the fitting,
and physically remove the obstruction.
•
Your Li’l Sucker can be used as a portable filter for your grinders that have only settling tanks.
Vacuum out the coolant and the swarf and return filtered coolant to the grinder tank. If the
standard polypropylene filter sleeve does not provide adequate filtration, fit the basket with our
disposable 20-micron paper filter bag. Note: Extremely fine grinding particles, such as carbide
grinding swarf, will pass through even the paper filter. Although the Li’l Sucker will do an
excellent job of removing the swarf from the grinder, you will experience a rapid accumulation
of fines in the Li’l Sucker tank.
•
If you are experiencing a problem in disposing of chips or swarf because of too great a
moisture content, your Li’l Sucker can be used as a chip “drier”. Vacuum out your machine to
remove all chips, fines, and then empty the Li’l Sucker of all coolant in the normal manner.
Open the suction inlet ball valve, start the unit in the suction mode, and allow it to run for 10 to
15 minutes. Air drawn into the Li’l Sucker will draw excess moisture from the chips and allow
them to be disposed of more easily. Be prepared to experiment with drying times; getting the
chips or swarf too dry will make it difficult to remove them from the filter basket.
•
Always empty the filter basket immediately after using the Li’l Sucker. Allowing the chips or
swarf to remain in the basket and the basket in the unit overnight or over the weekend can
cause the chips or swarf to corrode (rust) into a solid mass which is virtually impossible to
remove from the basket. This problem is especially pronounced with cast, nodular and
malleable irons.
•
Do NOT use your unit for solvents, volatile or low flash point fluids of any type. It is designed
for use with coolants, cutting oils, water-soluble machine cleaning solutions and parts washing
compounds only.

When pumping out of below-floor-level pits you can increase the efficiency of the suction by
drilling a small hole (1/8 inch, or 2 mm) in the pickup tube below where the hose is attached at
the cuff. By keeping this hole above the fluid level, you allow more air to enter the hose. That
helps to move the fluid up the hose faster and allow pumping out of deeper pits.
12
MAINTENANCE
1.
Check the filter basket’s polypropylene mesh filter sleeve frequently. If it is badly soiled or
clogged, remove the retaining ring on the inside of the basket. Lift out the sleeve, turn it inside
out, and wash in a suitable cleaner.
2.
If the filter sleeve is torn, or if it is soiled or clogged to the point where simple cleaning is
inadequate, replace the sleeve with a new one.
3.
To install a new sleeve: Fit the sleeve inside the basket, and fold the top edge over forming a
smooth edge. Make two small holes in the sleeve in order to slide it over the basket’s lifting
rings. Push the rings through. Fit the retaining ring on the inside of the basket, and fasten the
ring securely pushing the liner against the inside of the basket (Figure 2).
4.
Figure 2
Frequently check the basket lifting rings for signs of rust. If the rings become badly corroded,
replace the basket with a new one.
5.
If the filter sleeve is maintained in good condition, only fine particles should normally settle
out in the bottom of the tank. Remove these periodically by removing the discharge hose at the
90° elbow, and with the filter basket out of the Li’l Sucker, flush the tank with a water hose.
6.
Periodically, while the basket is out of the tank, check the tank interior for sludge buildup. If
such a buildup starts to get thick, use an appropriate tool to scrape it off the tank walls.
Remove the discharge hose and hose fitting from the bottom of the tank, and flush the tank
with a water hose.
7.
Periodically, check hoses for deterioration, and replace with new ones if leaks have developed
or appear imminent. Always coil hoses properly over the supports provided when not in use.
8.
Periodically, check the black suction/discharge hose for deterioration, replace with a new 3’
section if leaks have developed or appear imminent.
9.
Periodically, open the power head enclosure and inspect the black hose that connects the
vacuum motor to the enclosure plumbing outlet for deterioration. Replace with a new piece of
hose if leaks have developed or appear imminent.
13
Other than the routine maintenance operations specified above, only authorized service personnel
