(if applicable). Be certain the connection is securely tightened.
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.
If your unit is equipped with a water strainer, 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 flow of water to the pump. This can result in cavitation which will cause premature failure of pump packings.
a. Unscrew the strainer bowl from the unit.
b. Remove strainer screen and clean or replace.
3. Connect one end of the water supply hose to the water inlet of the unit.
Connect the other end of the hose to your pressurized water supply.
NOTE: If there is a high mineral content in your water, it is recommended that a water softener be used to prevent the possibility of excessive scale buildup inside the heat exchanger coil.
4.
Follow the incoming water requirements listed below: a. Water pressure must be between a minimum of 20 pounds per square inch (PSI) and a maximum of 125 PSI.
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 fill a 5 gallon container.) c. Incoming water temperature must not exceed 125 ° F. 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 completely turned on.

UNLOADER:
INSTALLATION & PREPARATION
Standard Models:
The unloader has been preset at the factory.
Steam Option Models:
The unloader has an adjustment knob which has a minimum/maximum setting. Move the unloader clockwise to the maximum setting for Cold/Hot water operation. Move counterclockwise to minimum setting for Steam operation.
HEAT DUMP 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 "heat dump 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, therefore preventing premature failure of pump packings.
PRE-START INSPECTION PROCEDURES:
Before starting the unit, perform the following procedures:
1.
Inspect the electrical cords for cuts. If a cut is found, DO NOT TOUCH OR
USE CORD! Replace cord before starting unit.
2.. Check the oil level in the pump.

DO NOT ALLOW SPRAY
PATTERN TO REMAIN ON A
FIXED AREA FOR AN EXTENDED
PERIOD OF TIME. POSSIBLE
DAMAGE MAY OCCUR TO THE
AREA.
START-UP/COLD WATER OPERATION:
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.
Ensure that the Switch is in the "OFF" position.
4.
Pointing the trigger gun in a safe direction, unlock the trigger gun and squeeze the trigger. Brace yourself for possible gun kickback when the pump starts.
5.
Move the Switch to the "Pump" position.
6.
Once the unit has started, perform the following procedures with the gun open: a. Inspect for system water leaks, oil leaks and fuel leaks.
If a fuel leak is found, TURN UNIT OFF IMMEDIATELY! See "Risk of
Explosion or Fire", pg. 5. 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 Customer Service.
b. Inspect high pressure hoses for kinking, cuts and leaks.
If a cut or leak is found, DO NOT TOUCH HOSE AT LEAK!!! TURN UNIT
OFF IMMEDIATELY! Replace hose before starting the unit. See "Risk of Injection or Severe Cutting Injury" pg. 6. 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 Customer Service.
7.
At this point, the unit is operating as a cold water pressure washer. Trigger the gun several times and try adjusting the water pressure by rotating the grip on the dual lance. NEVER place hand or fingers in front of the nozzle or look directly into the nozzle! High pressure water creates a risk of severe injury!
8.
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 packings, resulting in costly pump repair.
NOTE: If this unit is equipped with an Auto Start/Stop feature, the pressure washer will shutdown if the gun is not triggered after a designated amount of time. The pressure washer will start again once the gun is triggered.
The Auto Start/Stop feature is preset at the factory for shutdown at 90 seconds. It can be adjusted by an Authorized Service Technician to shutdown from no usage after a minimum of 3 seconds to a maximum of
5 minutes.
9.
Your pressure washer can deliver high pressure spray and a variety of spray patterns using cold water. If you wish to use the Hot Water, Steam application or Cleaning with Detergents, see page 19 for the correct procedures.

OPERATING INSTRUCTIONS
HOT WATER OPERATION:
1.
Follow the steps 1-8 outlined for "START-UP/COLD WATER OPERATION".
2.
Move the Switch to the "Burner" position. On initial start-up, water will begin turning hot in approximately 20 seconds and will reach maximum temperature in approximately 2-1/2 minutes, provided the trigger remains squeezed. The burner will stop firing when the trigger is released.
NOTE: While spraying, it is normal for the burner to fire intermittently. The high limit switch will cause combustion to cease when the temperature of the discharged water exceeds the temperature setting of the switch.
Combustion will begin again when the water temperature drops below the minimum setting .
At this point, the unit is operating as a hot water pressure washer. Be extremely cautious when adjusting the pressure and controlling the trigger gun/dual lance assembly to avoid the possibility of burns.
STEAM OPERATION:
1.
Follow steps 1-8 outlined for "START-UP/COLD WATER OPERATION".
2.
Ensure the quick-connect at the end of the dual lance is cool enough to touch, then remove the high pressure nozzle and replace it with the steam nozzle.
3.
Turn unloader knob completely counterclockwise to the minimum setting.
4.
Turn the Burner/Steam switch to "Steam".
NOTE: The burner will shut down if the switch is moved to "Steam" without first setting the unloader to minimum or operating in the high pressure mode.)
At this point, the unit will operate as a steam pressure washer. Be extremely cautious when adjusting the pressure and controlling the trigger gun/dual lance assembly to avoid the possibility of burns.
CLEANING WITH DETERGENTS:
NOTE: This feature is designed for use with mild detergents only. Since the cleaning solution travels through various parts of the pressure washer, do not use corrosives as they will cause extensive damage as well as pose a considerable safety hazard.
1.
Refer to "Risk of Bodily Injury / Detergents" pg. 7. Be certain to wear protective safety attire as stated on pg. 12.
2.
Prepare detergent solution according to label directions. (Never pump acids, alkalines, abrasive fluids or solvents through the unit. Due to the unknown and often corrosive characteristics of many detergents commonly used in the pressure washer cleaning industry, it is recommended to use only
Mi-T-M detergents with this unit.)
3.
Fully immerse the strainer end of the clear vinyl detergent hose into the detergent solution.
4.
DIRECT FEED: Be certain the adjustable grip on the dual lance is turned completely clockwise for low pressure detergent operation.
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 dual lance is set in the low pressure mode.
FLOAT TANK: Adjust the amount of detergent desired. Turn the metering valve completely counterclockwise to set at maximum siphon rate.
5.
To apply solution; unlock the trigger gun and squeeze the trigger. In a few moments a detergent/water mixture will exit the 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 briefly. Avoid working on hot surfaces or in direct sunlight to minimize the chances of the detergent drying, which may result in damaging surfaces. Be certain to apply cleaning solution to a small section at a time.
6.
To rinse; lock the trigger gun in the "OFF" position,
DIRECT FEED: Rotate the adjustable grip on the dual lance counterclockwise for high pressure.
FLOAT TANK: Turn the detergent metering valve to the "OFF" position.
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.
7.
Siphon a gallon of water through the detergent injection system after each use. This prevents the possibility of corrosion or detergent residue causing mechanical problems during the next use.

OPERATING INSTRUCTIONS
1.
Move the Switch to the "Pump" position.
2.
Squeeze the trigger and discharge the water for a period of three minutes to cool the heat exchanger and high pressure hose. (Insufficient cool down period of the high pressure hose will cause excessive wear and eventual rupturing of the hose.)
3.
Move the Switch to the "OFF" position. (Auto Start/Stop Option will shut the unit down, but total shutdown requires Switch to be moved to the
"OFF" position.)
4.
Turn off the water supply and trigger the gun momentarily to relieve trapped pressure.
5.
Disconnect and drain the high pressure hose, gun, and dual lance. Wipe the unit clean and store in a non-freezing environment.
STORAGE & MAINTENANCE
SPECIFIC MAINTENANCE:
PUMP: Change the pump oil after the first 50 hours of operation. After initial change, every 3 months or 250 hour intervals are recommended. If oil appears dirty or milky, changes may be required in greater frequency. Use Mi-T-M pump oil
(#AW-4085-0016) and fill only to the center of the oil sight glass. DO NOT overfill.
QUICK COUPLERS: There are o-ring seals inside the couplers which will deteriorate.
To replace, simply install a replacement o-ring to correct the leak. (Additional orings can be purchased from your dealer.)
NOZZLE: Water flow through the spray nozzle will erode the orifice, 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.
BURNER AIR ADJUSTMENT: The air shutter has been factory preset for proper operation between sea level and 2000 feet elevation at standard conditions (60 ° F ambient water and air temperatures). To assure maximum combustion efficiency at colder temperatures and higher altitudes, it will be necessary to adjust the air supply to the combustion chamber. A smoke spot test is recommended during any air shutter adjustment. This will aid in maximizing the burner efficiency and avoid the inefficient operation and excessive sooting of the combustion chamber.
1.
The machine must be running and the burner on.
2.
Take a smoke spot test to determine if more or less air is required for proper combustion.
a.
If the test is greater than a #3 smoke, turn the shutter arm counterclockwise to increase the air flow into the combustion chamber.
b.
If the test is yellowish in color, turn the shutter arm clockwise to decrease the air flow into the combustion chamber.
3.
Hold onto the air shutter adjusting arm and loosen the locking nut.
Move the shutter in 1/8" increments and retighten the locking nut after each 1/8" movement.
4.
Trigger the gun on and off slowly to make sure there is proper ignition.
Slight or no puffing on the ignition, and a smoke spot test of 0-3 is good.
5.
Repeat steps 2 and 3 until step 4 is attained.
LEAKS: Promptly eliminate any leaks found in the pumping system by removing suspect parts, applying thread sealant to the threads and reinstalling.
NOTE: If using teflon tape, be certain no tape gets inside any plumbing to prevent the possibility of a plugged spray nozzle.
