HSP Series Patented EMF System
In 1999, Mi-T-M Corporation received the patent for a unique ignition/ring system, called the Electro Magnetic Firing (EMF)
System, which produces enough voltage for operation and proper burning of the HSP Series hot water pressure washers.
This system is designed with two sets of magnets that are used to produce electricity. The rst set of magnets produces
a low voltage of about 12 to 14-volts when passed by a coil known as a stator. This voltage is required for operation of
the on/off switch, pressure and high limit switches and the fuel solenoid.
The second set of magnets passes by an ignition coil which
produces a high voltage in the tens of thousands of volts.
The spark is generated across the electrode gap and is
enough to create proper ignition of either No. 1 diesel,
No. 2 diesel or kerosene.
1. Engine sheave, dual set screw mount, maintains proper
alignment of pump shaft key.
2. The belt tension sheave creates proper belt tension so fuel
pump discharges fuel upon demand.
3. The long lasting, non-corrosive exible drive coupler
protects EMF system if fuel pump locks up.
4. Fuel pump is a durable high quality pump that will deliver
No. 1 or No. 2 diesel fuel or kerosene.
5. Stator coil/magnets are a low maintenance system that
provides solenoid control voltage.
6. Fan provides burner air for proper combustion and clean
exhaust smoke. It has an easily accessible air ow control.
7. Ignition coil provides voltage to electrodes for proper spark
voltage, allowing accurate ignition of fuel every time the
trigger is pulled. The ignition coil has a long life, is easily
replaced and has a proven track record in the industry.
EMF System eliminates
the need for a 12V battery.

HSP Series Burner Design
1. Large capacity exhaust tubes allow for proper exhausting of
combustion gases.
2. When troubleshooting a burner problem, the spark can easily be
checked within seconds through the convenient sight glass.
3. Continuous wrap tubing coil eliminates butt welds that can cause leaks.
The coil is lightweight and designed for easy replacement and durability.
4. The insulation pad is designed for easy replacement and durability.
5. Coil inlet/outlet connections and convenient coil drain allow for easy
draining of all water in coil to prevent freezing.
6. The combustion chamber drain allows for easy draining of water and
fuel build-up.
7. With Mi-T-M’s triple air ow design, the temperatures on the outer wrap
are kept low enough to eliminate the need for coil insulation. This also
increases the efciencies of the fuel being burned by the ignition on the
down-ow and the exhaust on the up-ow of the burner chamber.
8. Single wire-braided fuel hose prevents leakage, protects the system
and won’t crack or kink.
9. Electrodes and nozzle assembly are at top of burner for easy
maintenance and troubleshooting.
