Ryobi P747 Operation Manual - Page 6

OPERATION APPLICATIONS You may use this inflator for the purposes listed below:  Inflating high pressure items like motorcycle, car, and bicycle tires  Inflating and deflating low pressure items like air mat- tresses, rafts and floats NOTE: The inflator is not designed for commercial application. INSTALLING/REMOVING BATTERY PACK See Figure 1, page 10. To install:  Place the battery pack in the tool. Align the raised rib on the battery pack with groove in the battery port.  Make sure the latches on each side of the battery pack snap in place and that the battery pack is secured in the tool before beginning operation. To remove:  Depress the latches on both sides of the battery pack to release the battery pack and remove it from the tool. For complete charging instructions, see the operator's manuals for your battery pack and charger. DUAL HOSES See Figures 2 - 3, page 10. WARNING: Improperly attached hoses or accessories can become detached under pressure and cause serious injury. Possible air leaks can cause faulty pressure readings. Make sure all connections are tightly secured. The inflator has two hoses for two types of inflation. The high pressure hose is for inflating high pressure items like tires and sports balls. The low pressure hose is designed for inflating or deflating low pressure, high volume items like air rafts, mattresses, and floats. NOTE: Pressure gauge and preset features are relative only to high pressure hose applications. MODE/POWER BUTTON See Figure 4, page 11.  Press the mode/power button to turn on the unit.  To turn off the unit, press and hold the mode/power but- ton until the light turns off, then release the button. AUTOMATIC SHUTOFF The digital gauge will remain on for up to five minutes. To manually shut off, press and hold the mode/power button until the light turns off, then release the button. DIGITAL GAUGE See Figure 5, page 11. The digital gauge is multifunctional, serving as a pressure gauge and monitoring the amount of pressure being applied to the item being inflated. Pressure is indicated by PSI.  Press the mode/power button to turn on the digital gauge. The unit will start up in high pressure mode by default. NOTE: Make sure digital gauge is set at 0 before use. If gauge reads "Err" or needs to be reset to 0, press and hold both the mode/power button and start/stop button at the same time for approximately 5 seconds.  Press the mode/power button again to select the low pressure mode. Pressing the button one more time selects high pressure mode. The selected mode is indicated by the arrow on the left or right side of the display. Modes can be selected back and forth by pressing the mode/ power button. NOTE: After a high pressure preset has been set, the pressure setting stays in the memory until the unit is turned off. To recall the previous pressure setting after inflation, press the ( + ) or ( - ) button. INFLATING WITH THE LOW PRESSURE HOSE See Figure 6, page 11. The low pressure hose is used to inflate low pressure items, such as air mattresses, pools, and floats. NOTE: A pinch valve adaptor comes as part of the small inflatable nozzle assembly that is attached to the end of the low pressure hose. The pinch valve adaptor is used for items that have a smaller air opening or pinch valve. Insert pinch valve adaptor into pinch valve, insuring that the tip of the adaptor is inserted past the inner "flap" inside the valve. When inflating, ensure that the tip is not blocked during inflation.  Align the slots in the hose with the pins in the port on the top of the inflator.  Turn the hose clockwise as far as it will turn.  Press the mode/power button to turn on the digital gauge. The unit will start up in the high pressure mode by default.  Press the mode/power button again to select low pressure mode.  Press the start/stop button to start inflating.  When the desired pressure is reached, press the start/ stop button to stop inflating.  Remove the hose by turning it counterclockwise as far as it will turn and removing it from the inflator.  Store the hose in the hose wrap on the left side of the unit. 6 - English
