Years of experience, engineering, and planning have gone into the design and manufacturing of the M3-500. We take a great deal of pride in the M3-500; our goal is no less than your complete satisfaction.
• The two power cords must be plugged into separate circuits during operation. Each cord can be on a 15amp or 20amp circuit. If the M3-500 has an Auto Pump-Out system Cord #1 must be on 20amp circuit. The use of a Breaker Buddy (Hydro-Force part number AX49) will ensure that the two cords are operating on different circuits (see page 8 for details.)
Store, transport, and use this equipment only in temperatures well above freezing. (32ºF or 0ºC). If you suspect the M3-500 has been frozen, do not plug in or turn on machine until you are sure it has thawed completely.
SET UP AND OPERATION 1. Electrical Cords: Two 25’ power cords are supplied with the Olympus M3-500. Cord #1 powers Vacuum Motor #1 (and Waste Pump if equipped with optional Auto Pump-out System.); Cord #2 powers the high pressure Solution Pump and Vacuum Motor #2.
16-1/4oz of chemical to each gallon of water.) • The standard tip used with the M3-500 is the turquoise tip with a dilution rate of 256:1. This means that for each gallon of water flowing into the machine, 1/2 ounce of chemical will be added.
How to Change the Metering Tip: • Remove the chemical feed hose from the barb on the side of the proportioning valve. • Unscrew and remove the old tip. • Screw in the proper tip for your chemical tip and place the hose back on the barb Proportioning Valve Turquoise Tip Dilution 256 - 1...
Water Supply: • Once the correct metering tip is in place: o Connect the Auto-Fill Water Supply Hose to the water inlet (the male quick-connect on the front of the machine.) o Connect the other end of the hose to a water faucet, and then turn on the water. •...
3. Priming the High-Pressure Pump: Once water is in the solution tank, the high-pressure solution pump must be primed: • Connect the short prime hose to the solution outlet (female quick-connect on the front of the machine.) • Direct the end of the hose back into the solution tank and turn the solution pump switch to the ON position.
5. Connection of Vacuum Hoses: A 1-1/2” x 25’ Vacuum Hose is included with the M3-500. The 2” cuff on the 25’ vacuum hose is connected to the Vacuum Barb on the front of the machine. The other end with the 1-1/2” cuff is connected to the cleaning tool.
6. Optional Auto Pump-out System - Connection of Pump-out Hose: The pump-out hose is a 50’ section of 3/4” garden hose. • Remove the cap from the pump-out outlet fitting on the back of the machine. • Connect the pump-out hose to the outlet fitting. •...
7. Pressure Adjustment: When the high-pressure solution pump is on and primed, pressure will show on the gauge. • To decrease the pressure, turn the brass knob on the pressure regulator to the left (counter- clockwise.) • To increase the pressure, turn the brass knob on the pressure regulator to the right (clockwise.) •...
Shutdown Procedures: • If using the auto-fill system, turn the water supply off before finishing each job. This will allow use of the water and chemical already in the tank, and will reduce the amount of excess water to be disposed of later. •...

Section Maintenance Proper maintenance is required to keep the M3-500 operating properly, prevent downtime and to extend the life of your equipment. WARNING: Disconnect electrical power before performing any service or maintenance inside machine base or before testing or repairing switches or power cords.

Inside the recovery tank, on top of the stand pipe, is the Vacuum Shutoff Assembly. It functions to prevent debris and water from being sucked into the vacuum motors. Operating the M3-500 without the Vacuum Shutoff Assembly or with a poorly maintained assembly will greatly decrease the life of the vacuum motors and will void the warranty.
Page 27
A torn filter bag will allow debris past the filter and into the recovery tank. This debris can clog the Waste Pump and the Vacuum Shutoff Assembly. The Hydro-Filter must be examined and cleaned regularly to keep the M3-500 functioning properly: • Push the latch lever and open the Hydro-Filter lid.

LUBRICATE PRESSURE REGULATOR O-RINGS: To maintain consistent adequate pressure delivery to the cleaning tool, the piston seal of the M3-500 pressure regulator must be lubricated regularly. 1. Drain the solution tank before proceeding. Brass Knob 2. Remove Brass Knob from the regulator body.

CLEAN RECOVERY TANK DRAIN Debris and sand accumulation in the drain valve can damage the valve or prevent it from closing completely. This will result in dirty water leaking from the valve. Use of the Hydro-Filter and regular cleaning of the recovery tank will help prevent this, but occasionally the drain valve will require cleaning or replacement.

Then turn the solution pump off. 5. Connect any cleaning tools that will be stored with the M3-500. Turn the solution pump switch to the ON position. Direct tool spray back into the solution tank or into a bucket. Turn the solution pump off and repeat for all tools to be protected.
