OPERATION HIGH PRESSURE AIR HOSE See Figure 7, page 13. The high pressure air hose is used for inflating high pressure items like motorcycle, car, and bicycle tires. ACCESSORY COMPARTMENT See Figure 8, page 13. Inflator accessories can be stored in the accessory compartment located at the rear of the inflator. To open the accessory compartment, push down on the tab and lower the flip down door. INFLATOR ON/OFF SWITCH See Figure 9, page 13. To turn the inflator ON (I), depress the inflator on/off switch to the on position. To turn it OFF (O), depress the switch to the off position. INFLATING WITH THE HIGH PRESSURE AIR HOSE See Figure 10, page 13. The air chuck on the high pressure air hose can be used without adaptors to inflate tires or with any application that has a valve stem that fits the air chuck opening.  Turn the inflator off.  Position air chuck clamp in the unlock position perpendicular to the high pressure air hose.  Place air chuck on valve stem.  Push air chuck down so that the threaded section of the valve stem is inside the air chuck.  Clamp the end of the air chuck down onto the valve stem by pressing air chuck clamp down until it stops or is parallel with the high pressure air hose.  Turn on the inflator and inflate item to desired pressure. To determine air pressure using the pressure gauge, refer to instructions in the Using the Pressure Gauge section later in the manual. NOTE: When inflating items of 10 PSI., .69 BAR, .70 KG/ CM2 or less, inflate in short bursts and check after each burst by feel or with a reliable measuring device to determine accurate pressure.  Turn off the unit once inflation is complete. INSTALLING NOZZLES See Figure 11, page 13. WARNING: Improperly attached nozzles 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 high pressure air hose can be used with the provided inflation nozzles to inflate a variety of items.  Position air chuck clamp in the unlock position perpendicular to the high pressure air hose.  Insert nozzle into air chuck and push air chuck clamp down until it locks into place.  To remove, lift air chuck clamp up and remove nozzle from air chuck. NOZZLE FUNCTIONS See Figures 12 - 13, page 13. The inflator comes with two inflation nozzles and a sports ball inflation needle. The inflation nozzles can be used to inflate items with small pinch valves, which usually require the user to inflate them by blowing air into them. NOTE: When not in use, the inflation nozzles can be stored in the accessory compartment or in the nozzle clip on the back of the flip-down door. The sports ball needle can be used to inflate any type of sports ball or any other item that requires an inflation sports ball needle. To use the sports ball needle:  Insert sports ball needle into air chuck and push air chuck clamp down until it locks into place.  Insert sports ball needle into sports ball valve and in- flate.  Remove sports ball needle after inflation. NOTE: Pressure required for most sports balls is too low for accurate reading on gauge. USING THE PRESSURE GAUGE See Figure 14, page 14. Pressure gauge accuracy is ±5 psi from 0-100 psi and ±7 psi from 100-150 psi. To use the pressure gauge:  Place air chuck over valve stem and lock in place. NOTE: Do not turn the inflator on.  Wait 5-7 seconds for an accurate pressure readout. NOTE: The pressure readout on the gauge while inflating is a measurement of the fluctuating pressure between the item and the high pressure hose. To get an accurate reading, stop inflating and follow above instructions for reading the air pressure. CAUTION: Avoid over inflation. Always follow the maximum inflation guidelines stated by the manufacturer of the item being inflated. 10 - English
