POWERING THE UNIT
The
VEC251
can be powered by either the built-in rechargeable battery or the
12 Volt DC Power Adapter.
Powering the Unit Using the Built-In Rechargeable Battery
The built-in battery can power the compressor for short duration, cordless operation.
The battery should be fully charged before first use
(see “Charging/
Recharging the Battery”).
Powering the Unit Using the 12 Volt DC Power Adapter
The DC Power Adapter can operate the Air Compressor from an external 12 volt
power source for extended periods of time.
The DC Power Adapter features a gold-tipped, fused DC plug at one end and a barrel
connecter at the other. Simply connect the gold-tipped plug to a working 12 volt DC
power source, such as a vehicle’s 12 volt DC accessory outlet. Connect the barrel
connector to the 12 Volt DC Power Port on the back of the unit.
Note:
When using a vehicle’s 12 volt DC accessory outlet as a power source, be
aware that some vehicles require the ignition be turned on to power the
accessory outlet.
OPERATING INSTRUCTIONS
This
VEC251
is the ultimate compressor for vehicle and trailer tires and recreational
inflatables. Two different nozzles are supplied.
The Compressor ON/OFF Trigger controls operation of the compressor. Just depress
and release to control inflation. Control pressure by monitoring the gauge and releasing
the Trigger when the correct pressure is achieved. For longer inflation operations, push
Trigger Lock on to lock the Trigger in the ON position. Pushing the Trigger Lock to the
opposite direction releases the Trigger (turning it OFF) and inflation stops.
WARNINGS
The compressor is capable of inflating to 120 pounds per square inch
(PSI) pressure (approximately 8 kg/cm). To avoid over-inflation,
carefully follow instructions on articles to be inflated. Never exceed
recommended pressures. Bursting articles can cause serious injury.
Always check pressure with the pressure gauge.
Never leave compressor unattended while in use.
Allow the unit to cool for 15 minutes after 15 minutes of continuous
operation.
Inflating Items with Valve Stems
1. Unhook the Air Hose from its storage clamps.
2. Open the thumb latch and place the connector (chuck) on valve stem.
3. Push the connector toward valve stem and close the thumb latch.
4. Make sure the connector is pushed on to valve stem as far as possible before
closing thumb latch.
5. Press the Air Compressor Trigger to turn it ON (for larger items, engage the
Trigger Lock).
6. Observe pressure with the pressure gauge.

Control and Function Guide
CHARGING/RECHARGING THE BATTERY
All lead-acid batteries suffer from self-discharge over time and more rapidly when they
are used for prolonged periods or at higher temperatures. Therefore, these types of
batteries need periodic charging to replace energy lost through self-discharge.
The built-in rechargeable battery should be recharged as soon as possible after each
use. If it is allowed to remain in a discharged state, battery life will be reduced. When
the unit is not in frequent use, recharge the unit at least once every 60 days.
Notes:
The unit is delivered in a partially charged state. It MUST be fully charged
before using it for the first time using the supplied AC Charging Adapter. Initial
AC charging time is approximately 20 hours.
Recharging the battery after each use will prolong battery life; frequent heavy
discharges between recharges will reduce battery life. Overcharging will
reduce battery life. NEVER CHARGE FOR MORE THAN 36 HOURS.
The time required to fully recharge the built-in battery depends on the charge
status after use. Approximate recharging time is 12 hours.
The AC Charging Adapter must be powered from a standard 120 volt AC, 60 Hz
North American household outlet.
1. Insert the barrel connector of the AC Charging Adapter into the 120 Volt AC
Recharge Port on the back of the unit. Plug the AC Charging Adapter into a
standard North American 120 volt AC household outlet. The red Charging
Indicator LED lights, indicating the unit is charging.
2. Charge for the recommended time. Do not overcharge!
3. Disconnect the AC Charging Adapter from the unit and the 120 volt AC power
source when not in use.
