2 This Parts Listing has been compiled for your benefit. You can be assured your Mi-T-M hot water pressure washer was constructed and designed with quality and performance in mind. Each component has been rigorously tested to insure the highest level of quality. The contents of this Parts Listing are based on the latest product information available at the time of publication. Mi-T-M reserves the right to make changes in price, color, materials, equipment, specifications or models at any time without notice. WARNING THIS IS A PROFESSIONAL HIGH PRESSURE, HOT WATER PRESSURE WASHER. CAUTION SHOULD BE OBSERVED WHEN USING OR REPAIRING THIS UNIT! READ AND FOLLOW THE SAFETY WARNINGS LISTED BELOW BEFORE ATTEMPTING ANY REPAIRS ON THIS PRESSURE WASHER! SAFETY WARNINGS 1. NEVER alter or modify the equipment. Be sure any accessory items and system components being used will withstand the pressure developed. Use only genuine Mi-T-M parts for repair of your pressure washer. Failure to do so can cause hazardous operating conditions and will VOID warranty. 2. NEVER make adjustments on machinery while the unit is connected to the engine without first removing the ignition cable from the spark plug. Turning over the machinery by hand during adjustment or cleaning might start the engine and machinery with it, causing serious injury to the operator. 3. Know how to stop and bleed pressures quickly. Be thoroughly familiar with controls. 4. Before servicing the unit, turn unit off, relieve the water pressure and allow the unit to cool down. Do not make repairs while the unit is running. Service in a clean, dry, flat area. Block the wheels to prevent the unit from moving. Be especially careful to properly dispose of any flammable materials. 5. After testing the machine, DO NOT leave the pressurized unit unattended. Shut off the unit and release trapped pressure before leaving.

5 GENERAL THEORY OF OPERATION WATER FLOW: Connect a pressurized water source to the Inlet Garden Hose Connection (1) and turn on the water supply. The water will flow through a Water Strainer (2) which has a clear inspection bowl. The water then travels into the Triplex High Pressure Pump (3) which has an Unloader (4) that bypasses the water when the trigger gun is closed. To protect the pump from heated water during this bypass stage, a Heat Dump Valve (5) will open at 140 F/60 C allowing the heated water to escape. The Heat Dump Valve automatically resets when the water cools. The Pressure Switch (6) controls the fuel supply to the burner. When using detergents, the solution passes through the Detergent Strainer (7) located on the Detergent Hose (8). The detergent solution then travels into the Adjustable Low Pressure Detergent Injector (9). From there, the water may be allowed to flow out of the drain plug (10) or through the heat EXCHANGER INLET (11) where it is heated when the burner is on. As the water exits the Heat Exchanger OUTLET (12), it enters a safety system which protects the operator from danger. The safety system contains a High Temperature Limit Switch (13) which senses the water temperature and shuts off the fuel supply to the burner if it gets too hot. If the unloader fails to by pass the water or the burner remains on when the trigger gun is closed, the SAFETY RELIEF (14) will relieve and allow water to exit safely. The heated water then flows through the High Pressure Hose (15) and to the Trigger Gun Assembly (16) which allows the operator to control the water spray. When the trigger gun is open, the water flows through the Adjustable Pressure Dual Lance (17) and exits the Nozzle (18). FUEL FLOW: The Fuel Pump draws fuel from the Fuel Tank (19) through a replaceable Fuel Filter/Water Separator (20) and into the Fuel Pump (21). Fuel exits the fuel pump, into a Fuel Solenoid Valve (22) which controls fuel flow to the Fuel Nozzle (23) where it ignites and burns in the heat exchanger. EMF SYSTEM: The patented Electro Magnetic Firing (EMF) System is an integrated system which gives all the requirements for combustion. The Belt (1) from the power source turns the Hub (2) which has two Exterior Magnets (3) attached. As these magnets spin past the Ignition Module (4), a magnetic flux is created from which the ignition module produces a high voltage. This voltage arcs across the electrodes giving the spark that is needed for ignition. This hub has an Internally Mounted Magnet (5) which spins past a Stator (6) that produces the voltage that controls the fuel supply to the heat exchanger. In addition to this, the hub also spins the Blower Fan (7) that forces the air into and through the heat exchanger. The Fuel Pump (8) is also connected the hub by means of a flexible coupler.
