Charging The Unit Using The 12V Dc Charging Adapter; Using The Portable Compressor; Inflating Tires Or Products With Valve Stems In Auto Mode - Stanley AirPro 120 HRC120DS Instruction Manual

Charging the Unit Using the 12V DC Charging Adapter

1. Make sure the 120V AC Charging Adapter is disconnected.
2. Insert the double barrel tip of the 12V DC Charging Adapter into the 12V DC Charging Port on the back of the unit.
3. Insert the grooved tip of the 12V DC Charging Adapter into the vehicle's 12V DC accessory outlet or other functioning 12V DC power
source. When the unit is properly connected to an DC power source, the LCD Screen will display the following:
The bars on the Battery Icon represent the charge level of the unit's internal battery. The bars on the Battery Icon will change from
empty to solid (from bottom to top) repeatedly to indicate that the unit is charging. The backlight will turn on for 10 seconds (only).
Notes:
When using a vehicle's 12V DC accessory outlet as a power source, be aware that some vehicles require the ignition be turned on to power the
accessory outlet.
The bars on the Battery Icon will continue changing from empty to solid (bottom to top) repeatedly, but will not show 4 solid bars when using the
12 volt DC charging method. Manufacturer suggests that you only use the 12 Volt DC Charging Adapter if the unit needs to be charged immediately
and no 120 volt power source is available.
4. Charge for 5 hours. Do not overcharge.
5. Disconnect the DC Charging Adapter from the unit and the 12V DC power source when not in use.
CAUTION – TO REDUCE THE RISK OF DAMAGE TO THE UNIT: Do not charge for longer than 5 hours maximum using this method.

USING THE PORTABLE COMPRESSOR

This 12 Volt DC Air Compressor is the ultimate compressor for all vehicle tires, trailer tires and recreational inflatables. The compressor hose
with tire fitting is stored on the storage clips at the side of unit. A Nozzle Adapter is supplied and is stored in the Nozzle Adapter Storage
Compartment. Refer to the "Features" section to locate all components.
The 12V DC Air Compressor can be used in either Auto Mode or Manual Mode, as detailed in the following sections.
IMPORTANT: When the compressor is operated either in the Manual Mode or at a low PSI in the Auto Mode, the unit may start in low
and gradually rev up. When the compressor is operated at higher PSIs in Auto Mode, the unit may operate normally for several minutes,
then rev down for a few minutes before returning to normal operation. This feature protects the unit from overheating during normal
use. In any event, do not operate the compressor continuously for extended periods of time (approximately 10 minutes, depending on
ambient temperatures), as it may overheat. This could damage the compressor. If the compressor must be operated for longer periods:
every 10 minutes press and hold the Power Button for one second to turn the compressor off, then restart after a cooling down period of
approximately 30 minutes.
Note:
The 2-LED Area Light will remain lit as long as the unit is turned on.
WARNING: TO REDUCE THE RISK OF INJURY OR PROPERTY DAMAGE:
• Follow all safety instructions found in the "Specific Safety Instructions For Compressors" section of this instruction manual.
• The Air Compressor is capable of inflating to 120 pounds per square inch (PSI) pressure. To avoid over-inflation, carefully follow
instructions on articles to be inflated. Never exceed recommended pressures. Bursting articles can cause serious injury.

Inflating Tires or Products with Valve Stems in Auto Mode

In the Auto Mode, the desired pressure value can be preset and stored in the unit's memory and the compressor will automatically stop
once this preset pressure is reached. The Power Button turns the unit on and off. The Increase Pressure Control Button (+) and Decrease
Pressure Control Button (–) are used to select a pressure value for when the compressor is used in Auto Mode. All three buttons are
located on the control panel on the back of the unit (refer to the "Features" section to locate).
1. Make sure all charging adapters are disconnected.
2. Screw the SureFit nozzle onto the valve stem. Do not overtighten.

3. Press the Power Button to turn the unit on. The backlit LCD Screen will display the following, indicating the unit is in Standby Mode:
The digital display will alternately show the flashing pre-set PSI value (that was last set by the Pressure Control Buttons) for 2 seconds;
then it will flash the current pressure of the item being inflated for 5 seconds (which will then light solid).
IMPORTANT: If no other actions are taken after pressing the Power Button, the unit will automatically shut off after one minute of
inactivity.
4. Press the Increase (+) and Decrease (–) Pressure Control Buttons to select the desired pressure from a range pre-set values (between
3 and 120), which will display on the backlit LCD screen. Hold the Button to scroll upward or downward more quickly. Once the
