  • Why Propane Power?
  • Propane Power. Why Propane?

    20 lb. Propane Tank. Take Advantage of Safe, Clean and Efficient Propane Power.

    Propane powered machines give you virtually unlimited run time!

    Battery powered and corded machines can’t say that! Battery powered machines are limited by a 3 to 4 hour run-time on a single battery charge while corded machines are restricted by the location of electric outlets and cabling. With these types of machines, considerable down-time comes from charging batteries and moving cables. By contrast, a propane machines only down-time is during the fuel cylinder exchange. Propane machines are not hampered by electric cabling and they can move quickly throughout any facility.

    Propane powered machines give you more productivity in less time!

    Propane machines can deliver more than 6 times as much horsepower as other comparable electric machines. And unlike battery powered machines, that horsepower doesn’t diminish as the battery drains. Combined with the increased pad pressure, propane powered machines can deliver a higher levels of productivity with less effort and in less time. That translates into increased profits as well as a cleaner and healthier working environment.

    Propane powered machines give you cleaner and greener results!

    Electric and battery powered machines typically depend on electricity generated from coal fired power plants – a major contributor of green house gases and acid rain. Propane is a cleaner fuel that – when burned – produces mainly carbon dioxide and water. Any harmful by-products are held to very safe levels with specialized carburetion and catalytic converters that meet strict indoor air requirements from OSHA. Plus, the PE420GPHD Machines is equipped with the exclusive Eco Sense® Monitoring System ensuring machine operators and building occupants remain healthy and safe at all times.

    Eco Sense® Emission Monitoring System. The only technology in the floor care industry that automatically shuts the engine down BEFORE emissions can reach unsafe levels. If the machine air intake is clogged, the air-to-fuel ratio is off (improper filling of the propane tank) or the machine runs unattended, Eco Sense® will automatically turn off the engine before a minor problem can turn serious. And the Eco Sense® monitoring will continues after shutdown to ensure that the problem is corrected before the engine can start again.

    Tachometer, placed below the throttle.

    IMPORTANT: When filling your propane tank, it is important to bleed (empty the tank) prior to attaching it to the grinder. When bleeding, if a white mist (a liquid) appears, continue to bleed (purge) the cylinder until there is no white mist.

    HOW EFFECTIVE is ECO SENSE? If the propane tank was improperly filled (the tank wasn’t purged before filling and the white mist is evident), the grinder WILL NOT HAVE POWER (Torque). Just as important, because of the improper fuel/air mix ratio, Eco Sense will prevent the mixture from going to and damaging the engine.

    NOTE: If such a situation would occur, you’ll notice that the tachometer (picture) will not be showing high enough RPM. This is your notice to purge the propane cylinder to correct the propane mixture so the necessary RPM’s can be achieved.

    The Best Propane Power . . . vs. any other propane grinder!

    Power and Performance at a Fraction of the Cost.
    More Powerful. More Efficient. More Affordable.

    Engine Trottle Lever, 3 adjustment speeds: Idle, 1000 & 1500 rpm.
    Engine Throttle (pictures, right and top right – lever with yellow rubber cap). The machine is equipped with a throttle with three positions:
    · 1st position, is idle
    · 2nd position, to grind and polishing @ 1000 rpm
    · 3rd position, strictly for burnishing @ 1500 rpm.

    Head Pressure

    Fine tune adjustments to increase or decrease down pressure.

    * Important * Besides the versatile features of having two speeds for grinding, polishing and burnishing, and of adding weight plates to increase or decrease “head pressure” (directly above the driver – exactly where it is needed), you’re also able to adjust the machine’s rear wheels to provide the exact down pressure the application may need. – – – “One Machine. One Solution.”

    Procedure: In the roll-back position (with the grinder tilted backwards and resting on its T-handle), you see that there are two (2) wheel locations – each with two (2) holes. The front location is for burnishing, the rear location (closer to the T-handle) is for grinding.

    In the forward hole, the driver plate will be laying perfectly flat to the floor. In the rear hole, head pressure is further increased by angling the driver plate to a 4 o’clock position on the floor.

    Rear Wheel Adjustment - Front 2 holes (towards front of machine), for polishing and burnishing.
    Burnish Position: Front location, front and rear holes.
    Rear Wheel Adjustment - Further 2 holes (rear), for grinding.
    Grinding Position: Rear location, front and rear holes.

    Weight Plates (5) & Steel Dust / Splash Guard.Weight Plates & Wheel Settings. Before beginning any project you always start with the wheels in the rear holes and use no weights. If you feel more down pressure is needed, add the weight plates as needed for increased head pressure. For coatings removal, if the surface is tacky, you may improve results by using less weights and positioning the wheels in the front holes.
