    Chem-Dry PowerHead ® ® CONTROL FUNCTIONS There are control triggers located on each side of the handle under the rubber hand grips.

The Safety switch located on the top of the handle must be depressed while the trigger is pulled.

  • Page 17: Edging Tool

    Chem-Dry PowerHead ® ® Once you have become familiar with the speed and movement of the machine, practice making it hover in one spot. (The hovering maneuver is useful for removing stubborn stains, as well as removing furniture indentations.) Do not tilt machine sideways while moving forward and backward (see Figure 4-3).

  • Page 19: Cleaning Information

    Chem-Dry PowerHead ® ® 5 - Cleaning Information CLEANING PATTERNS For regular carpet cleaning, use an overlapping arc pattern, two times over the same area (one pass with solution and one pass for drying). When cleaning carpets, first clean in circular pattern, then use the overlapping arc pattern to dry the area (see Figure 5-1). Figure 5-1.

  • Page 20: Special Information

    Chem-Dry PowerHead ® ® DO NOT operate your PowerHead over loose or unraveled carpet seams. The cleaning head may catch and cause further damage. DO NOT operate your PowerHead on concrete floors. Sharp edges will develop on the extraction heads which will damage carpet fibers. DO NOT clean over the edge of a loose carpet.

  • Page 21: Cleaning Hints

    Chem-Dry PowerHead ® ® CLEANING HINTS Most cleaners customarily clean their way out of an area or room. With the PowerHead, it is possible to clean into an area or room, as shown in Figure 5-2, so that the hoses are dragged behind you during the cleaning process rather than kicked out of the way as you back out of an area.

  • Page 23: Machine Maintenance

    Chem-Dry PowerHead ® ® 6 - Machine Maintenance Good care and regular maintenance of your PowerHead will result in a long, dependable life for the unit. Keep in mind that your PowerHead will be in full view of your customer. A PowerHead that is dirty and unkempt in appearance can cause your business or professional image to suffer.

    30 weight SAE motor oil (see Figure 6-4). Also, put a few drops into the hub threads. Coat the shaft with TKX® All-Purpose lubricant (HydraMaster P/N 000-087-006 – see Figure 6-5). Re-install the vacuum head assembly onto the shaft by rotating it counterclockwise.

  • Page 25: Periodic Maintenance

    Chem-Dry PowerHead ® ® While rotating the vacuum head assembly in the counterclockwise position, make sure that it spins freely all the way down. If it begins to require the slightest finger tip pressure, unscrew it and brush off the threads. All it takes is the slightest grain of dirt or sand to obstruct the threads.
