5. USING THE JUMP STARTER
IMPORTANT: Using the Engine Start
feature without a battery installed in the
vehicle will damage the vehicle’s
electrical system.
1. Turn the ignition OFF.
2. Make sure the area is well ventilated.
3. Lay the DC cables away from any
fan blades, belts, pulleys and other
moving parts.
4. Make sure the rotary switch on the
front panel is in the O (OFF) position
until the clamps are connected to the
vehicle. If plugged into an AC wall
outlet, unplug.
5. DO NOT allow the clamps to touch
together or to contact the same piece
of metal.
6. For a negative-ground vehicle (as
in most vehicles), connect the jump
starter’s POSITIVE (RED) clamp to the
POSITIVE (POS, P, +) battery post.
Next, connect the NEGATIVE (BLACK)
clamp to the vehicle chassis or engine
block, away from the battery.
7. For a positive-ground vehicle,
connect the jump starter’s NEGATIVE
(BLACK) clamp to the NEGATIVE
(NEG, N, -) battery post. Next,
connect the POSITIVE (RED) clamp
to the vehicle chassis or engine block
away from the battery.
IMPORTANT: If you have connected the
clips backwards, an audio alarm will
sound. DO NOT turn on the jump starter.
This could cause serious damage to the
jump starter or the vehicle. Reverse the
connections and the audio alarm will stop.
8. If no audio alarm sounds, turn the
rotary switch to the 12V position (12V
or 24V position for Model PSJ-4424).
The 3-digit display will show the
voltage of the battery.
9. Crank the engine. If the engine does
not start within 5-8 seconds, stop
cranking and wait at least 1 minute
before attempting to start the vehicle
again. (This permits the battery to
cool down.)
10. After the engine starts, turn the
rotary switch to the O (OFF) position.
Disconnect the black clamp (-) and
then the red clamp (+), in that order.
11. Recharge the jump starter as soon as
possible after use.
POWERING A 12V DC DEVICE
The jump starter is a power source for all
12V DC accessories that are equipped
with a 12V accessory plug. Use it for
power outages and on shing or camping
trips. Estimated usage times are listed in
the chart.
NOTE: Do not power a 12V device with
the jump starter while charging the
internal battery.
1. Make sure the device to be powered
is OFF before inserting the 12V DC
accessory plug into the 12V DC
accessory outlet.
2. Ensure the battery clamps are
secured on the storage holders.
3. Open the protective cover of the DC
power outlet on the jump starter.
4. Plug the 12V DC device into the DC
power outlet and turn on the 12V DC
device (if required).
5. When nished, turn off the DC device
(if required) and unplug from the DC
power outlet.
NOTE: Do not use the jump starter
to run appliances that draw more than
15A DC. If the 12V DC device draws
more than 15A or has a short circuit, the
internal circuit breaker of the jump starter
will trip and disconnect the power to the
device. Disconnect the 12V DC device.
The breaker will automatically reset after
an overload occurs.
NOTE: Extended operation of a 12V DC
device may result in excessive battery
drain. Recharge the jump starter
immediately after unplugging the 12V
DC device.
