USING THE AIR COMPRESSOR

To inflate tires:

1.  Remove valve cap from air valve stem.

 

Note: Make sure locking thumb lever is at up position. If necessary, use valve stem adapter.

2.  Insert stem connector to valve stem. Make sure connector is pushed to valve stem as far as possible.

3.  Press down the locking thumb lever to engage.

4.  Set the compressor on/off switch to “on” position by pressing down the section of switch marked “I”.
 

Note: 

In the event that the tire is completely flat, raise the vehicle using a recommended jack before inflating the tire.

5.  Monitor pressure on air pressure gauge.

6.  When desired pressure is reached, turn off compressor.

 

Turn the locking thumb lever to up position and remove stem connector from valve stem. Also remove valve stem  

 

adapter if applicable.

7.  Replace valve cap on valve stem.

To inflate plastic inflatable (balls, air mattresses, rubber rafts, etc.):

1.  Check manufacturer’s specification on item to be inflated for correct inflation pressure.

2.  Remove valve cap cover from valve stem.

3.  Insert proper valve stem adapter into stem connector as far as possible and turn the locking thumb lever to down position. 

 

4. Insert other end of valve stem adapter into inflatable air valve stem as far as practical.

5.  Set the compressor on/off switch to “on” position.

6.  Monitor pressure on air pressure gauge. When desired pressure is reached, turn off compressor, turn the locking thumb  

 

lever  to  up  position  and  remove  stem  connector  from  valve  stem.  Also  remove  valve  stem  adapter  if  applicable.  

 

Replace valve cap on valve stem.

DC POWER SOCKET OPERATION

This Power Station is equipped with a 12-volt DC power socket.  It can operate 12-volt DC automobile, RV, marine, or other 

portable appliances that draw less than 10 amps from a 12-volt DC power socket or from a vehicle’s cigarette lighter/ac-

cessory socket.

OPERATING A DC DEVICE

1.  Remove the protective cover from the DC power socket.

2.   Plug the 12-volt DC appliance into the power socket, then turn the appliance on (if required). If the appliance draws  

 

more than 10 amps (or has a short-circuit defect), the internal circuit breaker of the Power Station shuts off the power  

 

to the appliance.  If this occurs, unplug the appliance. The internal circuit breaker automatically resets after a few  

 

seconds.

3.   Fully recharge the Power Station as soon as possible after each use.  As the DC power socket is internally wired directly  

 

to the Power Station’s battery, extended operation of a 12-volt DC appliance may result in excessive battery discharge.

STORAGE

This unit may be stored in any position. Make sure the clamps are secure inside the booster cable storage covers. Store at 

room temperature. If not used for a prolonged period of time, recharge every 2 months in the winter and every month in 

the summer.

SPECIFICATIONS

Battery: 

12 Volt 8AH sealed lead acid, maintenance free, 

 

   

spill-proof, rechargeable.

Power Supply DC Output: 

12-volts nominal.

Air Compressor: 

260 PSI

Power Supply Charging Time: 

28 hours with AC charger; 8 hours to recharge with 

Storage Temperature:

WARNING: 

Check item to be inflated for manufacturer’s maximum recommended inflation pressure. Avoid 

over inflation. Most tires are properly inflated between 24-35 PSI. Some truck and bicycle tires 

require 40 PSI or more.
