8. Insert the male plug into a grounded AC outlet. DO NOT use an adapter
OR remove the grounding plug!!
NOzzLE REVIEw:
Various nozzles may be quick-connected into the end of the wand to change
the spray pattern or use the detergent feature. When using Quick Connects
(Q.C.), be certain the connection is securely locked. If not, the high pressure
water may shoot the nozzle from the wand, causing severe injury or serious
damage. To determine spray fan, refer to the actual number stamped on the
nozzle. The rst two digits indicate the spray fan in degrees, i.e.; 00=0”, 15=15°,
25=25°, 65=detergent/low pressure.
1. The 0” nozzle (RED): This is a blasting nozzle. It delivers a very concentrated
stream of water. Be cautious when using the straight narrow stream. It is
not recommended for use on painted or wood surfaces, or items attached
with adhesive backings. Uses: Removing weeds from sidewalk cracks,
stubborn stains from concrete, masonry, aluminum and steel, caked mud
from equipment, and cleaning lawn mower undersides.
2. The 15° nozzle (YELLOw): This is a chiseling nozzle. The spray should
be directed at a 45° angle to the surface and used like a scraper to remove
paint, grease and dirt. Uses: Surface preparation (removing mildew stains
and paint chips).
3. The 25° nozzle (GREEN): This is a ushing nozzle. This pattern is best
suited for ushing dirt, mud, and grime. Uses: Wet sweeping leaves from
walks, curbs and driveways, cleaning stable oors, washing swimming pool
bottoms, degreasing engines.
4. The 65° nozzle (bLACK): This is a low pressure detergent application
nozzle. This broad spray pattern distributes solution over vast areas under
low pressure. Uses: Detergent application, misting or rinsing.

QUICK-CONNECT FITTING
wATER SUPPLY:
1. Select a water supply hose which is a quality grade of garden hose measuring
at least 3/4" ID and no longer than 50 feet.
2 Check the water inlet strainer to ensure it is clean and free of any obstructions.
Periodic cleaning of the water strainer will help prevent pump problems. As
a strainer becomes obstructed, it restricts proper ow of water to the pump.
This can cause cavitation which will result in premature failure of pump
packings and valves. Using a screw driver, remove the screen; clean or
replace with Mi-T-M #19-0001 if necessary.
3. Connect the hoses.
a. Connect one end of the water supply hose to the water inlet of the
unit.
b. Connect the other end of the hose to your pressurized water supply.
NOTE: Do not use a non-pressurized water supply (i.e. from a well or pond)
with this unit.
c. Connect the high pressure discharge hose to the water outlet of the
unit.
4. Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 20 pounds per square inch (PSI)
and a maximum of 125 PSI. (A typical outdoor faucet will generally
supply this PSI if turned completely "ON".)
b. Incoming GPM must be approximately one gallon more than the outgoing
GPM stated on the pressure washer nameplate. (You can check GPM
by timing how long it takes to ll a 5 gallon container.
c. Incoming water temperature must not exceed 140°F (78°C). Excessive
pump damage may result if the water temperature exceeds this acceptable
level.
5. Never allow the unit to operate without the incoming water line attached and
the water supply turned all the way on.

INSTALLATION & PREPARATION
THERMAL RELIEF VALVE:
To ensure the water temperature does not exceed acceptable levels, never allow
the pressure washer to operate in the bypass mode (with the unit running and
the trigger closed) for more than three minutes.
A thermal relief valve has been added to this unit to protect the pump. This valve
will open and release water if the water temperature in the pump has exceeded
140° F. This will allow fresh, cool water to enter the system, preventing premature
failure of pump packings.
PRE-START INSPECTION PROCEDURES:
Before starting the unit, perform the following procedures:
1. Inspect electrical cord for cuts. If a cut is found, DO NOT TOUCH OR USE
ELECTRICAL CORD! Replace cord before starting the unit.
2. Check the oil level in the pump.
3. Inspect the inlet water strainer. Clean or replace if necessary. See "Water
Supply", #2, pg. 15.
4. Check all hose connections to ensure they are securely tightened. See
"Water Supply", #3, pg. 15.
5. Inspect for system water leaks and oil leaks. Be sure that all damaged
parts are replaced and that the mechanical problems are corrected prior to
operation of the unit. If service is needed, contact Customer Service.
6. Inspect high pressure hose for kinking, cuts or leaks. If a cut or leak is
found, DO NOT USE HOSE! Replace hose before starting unit. Be sure
that all damaged parts are replaced and that the mechanical problems are
corrected prior to operation of the unit. If you need service, contact Customer

OPERATING INSTRUCTIONS
PRIMING THE PUMP:
1. It is essential to prime the pump on initial start-up and each time the water
supply is disconnected from the unit after initial use.
2. Lay the high pressure hose out to remove any loops. Water ow will constrict
the hose, creating tight loops if the hose is not straight.
3. Securely connect the gun assembly to the high pressure hose.
NOTE: The nozzle should NOT be connected to the gun assembly at this time.
See "Nozzle Connection" pg. 14.
4. With the trigger gun locked in the "OFF" position, turn the water supply
completely on. Pointing the gun in a safe direction, unlock the trigger gun
and squeeze the trigger.
5. Low pressure water will begin owing from the hose/gun assembly. This
allows the unit to prime and purge any air from the system. The unit is
primed when water ow is uninterrupted by air.
6. Once the unit is primed, release the trigger and lock the gun in the "OFF"
position. Securely connect the nozzle assy. (See "Nozzle Connection" pg.
14.)
START-UP:
1. Refer to the "Safety Precautions" pgs. 4-7 before starting the unit.
2. Locate the Safety Decals on your unit and heed their warnings.
3. With the gun locked in the "OFF" position, point the trigger gun away from
yourself or anyone else. Ensure water supply is turned completely on.
4. Disengage the safety lock-off on the gun and squeeze the trigger. Low
pressure water will begin owing from the nozzle.
5. Before starting the unit, brace yourself as the gun will kickback from the
high pressure created by the pump once the unit has started.
6. Move the switch to the "ON" position. This switch includes a circuit breaker
for protection of the motor. In case of excess load, the circuit breaker will
automatically move the switch to the "OFF" position. To restart, move the
On/Off Switch to the "ON" position again.
7. Once the unit is turned on, perform the following procedures with the gun
open:
a. Inspect for system water leaks and oil leaks. If a leak is found, TURN
UNIT OFF IMMEDIATELY! Be sure that all damaged parts are replaced
and that the mechanical problems are corrected prior to operation of
the unit. If you require service, contact Mi-T-M Customer Service.
b. Inspect high pressure hose for kinking cuts and leaks. If a cut or leak is
found, DO NOT TOUCH HOSE AT CUT OR LEAK!!! TURN UNIT OFF
IMMEDIATELY! Replace hose before restarting the unit. Be sure that
all damaged parts are replaced and that the mechanical problems are
corrected prior to operation of the unit. If you require service, contact
Mi-T-M Service.
c. Inspect electrical cord for cuts. If a cut is found, DO NOT TOUCH OR
USE ELECTRICAL CORD! Replace cord before starting the unit.

8. Trigger the gun several times. be certain to LOCK the trigger gun in the
"OFF" position whenever changing the nozzle. NEVER look directly into
the nozzle! High pressure water creates a risk of severe injury!
9. Do not allow unit to operate in bypass mode (with trigger closed) for more
than three minutes without triggering the gun. Failure to follow this simple
rule can cause premature failure of pump packing seals, resulting in costly
pump repair.
10. Because your pressure washer delivers a high pressure spray and a variety
of spray patterns, there are many cleaning jobs that can be done without
the use of detergents. If a cleaning agent is required, see "Cleaning With
Detergents" pg. 17 for the correct procedures.
Page 17
OPERATING INSTRUCTIONS
CLEANING wITH DETERGENTS:
1. Refer to "Detergent Cleaning Precautions" pg. 7 before working with
detergents. Be certain to wear protective safety attire as stated on pg.
12.
2. Prepare detergent solution according to label directions. Never pump
acids, alkaline, abrasive uids or solvents through the unit.
3. Your injector is equipped with an adjustment knob on the pump head,
you may adjust the amount of detergent desired by turning the knob
completely counterclockwise to set at the maximum siphon rate.
4. Immerse the detergent strainer into the detergent solution to allow
detergent to siphon.
5. With the trigger gun locked in the "OFF" position, securely quick-connect
the detergent spray nozzle (#6540° BLACK) into the end of the wand.
NOTE: This injection system is designed to apply detergents under
low pressure only. It will not allow detergent solutions to be
introduced into the system unless the detergent nozzle (6540
Black) is installed.
6. To apply solution; unlock the trigger gun and squeeze the trigger. In a
few moments a detergent/water mixture will exit the low pressure nozzle.
Start spraying the lower portion of the surface being cleaned and move
up, using long overlapping strokes. Applying from the bottom up helps
avoid streaking. Allow to soak briey. DO NOT allow detergent solution
to dry on the surface. (Avoid working on hot surfaces or in direct sunlight
to minimize the chances of the detergent drying, which may result in
damaging painted surfaces.) Be certain to rinse a small section at a
time.
7. To rinse; lock the trigger gun in the "OFF" position, securely quick-connect
the desired high pressure nozzle into the end of the wand. Unlock the
trigger gun and spray. It will take about 30 seconds to purge all detergent
from the line. For best rinsing results, start at the top and work down.
8. Siphon a gallon of water through the low pressure detergent injection
system after each use. This prevents the possibility of corrosion or
detergent residue causing mechanical problems during the next use.
QUICK CONNECT DETERGENT
SHUTDOwN:
1. Move the switch to the "OFF" position to turn unit off.
2. Turn the water supply off.
3. Pointing the gun in a safe direction, trigger the gun momentarily to relieve
any trapped pressure.

STORAGE & MAINTENANCE
SPECIFIC MAINTENANCE:
PUMP: The pump oil must be changed after the rst 25 hours of operation.
Once the initial oil change has been completed, it is recommended the
oil be changed every 3 months or 250 hour intervals. If oil appears
dirty or milky, changes may be required at a greater frequency. Use
Mi-T-M pump oil #AW-4085-0016 and ll only to the center of the
oil sight glass. DO NOT OVERFILL!
NOZZLES: Water ow through the spray nozzle will erode the orice, making
it larger, resulting in a pressure loss. Nozzles should be replaced
whenever pressure is less than 85% of the maximum. The
frequency of replacement will depend upon such variables as
mineral content in the water and number of hours the nozzle is
used.
QUICK COUPLERS: There is an o-ring seal inside the female quick coupler.
This o-ring will deteriorate or, if the unit is allowed to pump without
the high pressure hose or nozzle attached, the o-ring may be blown
out occasionally. Simply insert a replacement o-ring to correct the
leak. (Additional o-rings can be purchased from your dealer.)
wINTERIzING:
For storage and transportation purposes in subfreezing ambient temperatures,
it will be necessary to winterize this unit. This unit must be protected to the
lowest incurred temperature for the following reasons:
1. If any part of the pumping system becomes frozen; excessive pressure may
build up in the unit which could cause the unit to burst resulting in possible
serious injury to the operator or bystanders.
2. The pumping system in this unit may be permanently damaged if frozen.
FREEZE DAMAGE IS NOT COVERED BY WARRANTY.
