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 fishing 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 finished, 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.
