PURPOSE
The Mi-T-M Pit Cleaning System uses your existing Pressure Washer to operate a high volume Sludge Pump. This
Sludge Pump will move liquids, sludge, and solid debris from the bottom of a pit, through 1 ½” PVC pipe and hose, into
the Sludge Cart where it is deposited into a Filtration Bag. The Filtration Bag may then be disposed of in any manner
compliant with EPA standards.
The Pit Cleaner connects to your Mi-T-M pressure washer in place of its standard gun/lance assembly, and uses the
force of the high pressure water to create a vacuum to remove debris and sludge from the pit. The Pit Cleaner comes
with a #4 nozzle which will work with a variety of pressure washers ranging from 1000-4000 PSI and 2–4 GPM. The Pit
Cleaner has a 1:11 flow ratio; a 3 GPM pressure washer will produce a flow of 33 GPM. The more powerful the pressure
washer, the higher volume of debris is removed from the pit.
NOTE: The actual output volumes will vary with the weight and particle size of the material being removed and the
height and distance that the material is moved. For best results with heavier or larger particles use a pressure
and flow nearer to the high end of the suggested pressure and flow.
The following is a chart showing the relationship of pressure and flow for various nozzles in GPM.

IMPORTANT SAFETY WARNINGS
WARNING: When using this product, basic precautions should always be observed, including the following:
READ ALL SAFETY WARNINGS BEFORE USING PIT CLEANING SYSTEM
HAZARD
POTENTIAL CONSEQUENCE
RISK OF BURSTING
Serious injury or death could occur
from bursting.
Do not use this accessory to pump flammable
material! An explosion could occur from a gas
vapor buildup inside the system.
Serious injury may occur if attempting
to start the unit when frozen.
In freezing temperatures, the unit must always
be warm enough to ensure there is no ice
formation in the accessory. Do not operate
the accessory if it has been in a freezing
environment without first allowing to thaw.
Serious injury may occur from
exploding accessories if incorrect
system components, attachments
or accessories are used.
RISK OF INJECTION OR
SEVERE CUTTING INJURY
Serious injury or death could occur
from high pressure spray penetrating
the skin.
PREVENTION
Use only manufacturer recommended repair
parts for the unit.
Keep clear of nozzle and spray! Never put
your hand, fingers or body directly over the
spray nozzle.
Never point the high pressure discharge spray
at yourself or anyone else.
SEEK EMERGENCY MEDICAL CARE if the
spray appears to have penetrated the skin!
DO NOT TREAT AS A SIMPLE CUT!!
Do not move the unit by pulling on the hose.
High pressure hoses should be inspected
daily for signs of wear. If evidence of failure
exists, promptly replace all suspect hoses to
prevent the possibility of injury from the high
pressure spray. If a hose or fitting is leaking,
NEVER PLACE YOUR HAND DIRECTLY ON
THE LEAK.
NEVER operate the gun with the trigger wired
in the open position. To prevent accidental
discharge, the trigger gun should be securely
locked when not in use.
Before removing the spray nozzle or servicing
the unit, ALWAYS shut off the unit and trigger
the gun to release trapped pressure. (Even
after you shut off the unit, there is high pressure
water left in the pump, hose and gun until you
release it by triggering the gun.)

PIT CLEANER SYSTEM FLOW CHART
High-pressure water flows from the existing Pressure Washer (1) into the Gun/Lance (2) of the Pit Cleaner where it is
directed into the Sludge Pump (3). The high-pressure stream is directed up into the PVC Body (4) of the Pit Cleaner
creating a vacuum (venturi effect) at the bottom opening of the Sludge Pump. This vacuum pulls liquids, sludge, and or
solids from the bottom of the pit into the PVC Body (4) of the Pit Cleaner where it mixes with the high-pressure flow from
the Pressure Washer (1). This mix is then forced out through the back end of the Pit Cleaner and into the PVC Hose
(5), the hose directs the mixed flow into the Sludge Cart (6). The mixed flow is then deposited into the Filtration Bag
where the solids and sludge materials are filtered from the water, and retained in the bag allowing the cleaned water to
return to the pit system.

PIT-0026-113099-JJ
EXPLANATION OF SLUDGE PUMP OPERATION
High-pressure water flows into the Sludge Pump through a 0° nozzle and is injected into the body of the Pit Cleaner. As
the high-pressure water is flowing up the PVC body of the Pit Cleaner a vacuum (venturi action) is formed at the bottom
end of the Sludge Pump. Debris and Sludge from the pit is pulled up into the high pressure stream and out through the
body of the Pit Cleaner.

male adapter of the main wand assembly.
2. Insert the sludge pump assembly into the coupler on the extension assembly and pull the levers back to lock in
place.
3. Attach the lance assembly to the main wand assembly by pressing the pipe into the clamps until the clamps are
fastened securely (two clicks).
4. Attach the quick connect from the lance assembly to the plug of the sludge pump assembly.

Mi-T-M® Pit Cleaner Operator's Manual
OPERATING INSTRUCTIONS
PIT0025-JJ
1. Place the Sludge Carrier on the wash pad so that water will drain to catch basin.
2. Attach one of the Biodegradable filter bags to the Sludge Carrier by pushing the bolts through the burlap weave of
the bag. Make sure all eight bolts are pushed through the bag.
3. Connect one end of the Flex Hose to the cam lock fitting of the Sludge Carrier and the other end to the cam lock
fitting on the top of the Pit Cleaner Assembly.
4. Attach the gun of the Pit Cleaner Assembly to the pressure washer with a hose that has a 3/8” female quick-connect
fitting.
5. Start the pressure washer
6. To clean the pit, insert the head of the Pit Cleaner Assembly into the sludge at the bottom of the pit and pull the
trigger on the gun.
7. The unit is operating correctly when you can feel a surge of fluid through the flex hose and see the sludge dump into
the Biodegradable filter bag.
8. If the unit is not working correctly, check the following causes:
a. The sludge is too thick to pump up the Pit Cleaner Assembly. Move the Pit Cleaner Assembly up and down in
the pit to dislodge the sludge or remove it from the pit to flush out the sludge.
NOTE: The pressure washer must be shut off before checking causes "b-d".
b. An object is lodged in the head of the Pit Cleaner Assembly. Remove the head if necessary to dislodge the
object.
c. Sludge has plugged the Pit Cleaner Assembly or Flex Hose. Undo cam lock fittings and remove obstruction.
d. The nozzle in the head of the Pit Cleaner Assembly is clogged. Remove the head and use a 9/16” socket to
remove and clean out the nozzle.
NOTE: Some debris cannot be removed from the pit. It may be necessary to periodically empty the pit and shovel the
debris out by hand.
9. When a bag is full, stop cleaning the pit and disconnect the hose from the Sludge Carrier and cart it over to a drainage
area. Tie off the bag and remove it from the cart to let it drain. It may take a couple hours to drain the bag.
10. Place the next bag on the Sludge Carrier and continue cleaning, replacing the bag when necessary.
