Locations of the fuses:
Depending on the model of Start Booster, the fuse can be located in various places:
- On the booster itself, either on the front or the back of the unit.
- Inside the handle of the positive clamp.
Our fuses come with a small window to see if the fuse is broken or not. Sometimes,
depending on the features, you might have an extra spare fuse directly built-in the
unit itself to be able to change it if the one connected has burst. Fuses are very easy
3. FEATURES
A. SAFETY FUSE
If your Start Booster is equipped with a Safety Fuse please read the following:
Fuses have been developed to protect your Start Booster and vehicle against reverse
polarities. If your jump starter is not already equipped with a safety, you still have the
possibility to add a new type of clamp with a built-in safety fuse. Please contact your
distributor directly to ask if your device is compatible.
Different Types of Fuses:
Fuses exist in various sizes: 300A – 500A – 1000A. Please check which fuse was in-
stalled in your device before ordering a new one. You can ask your distributor if you
need to change a fuse. Please make sure that you use a recommended fuse only.
Using a fuse that is not approved will void the warranty.

to change. First open the window with a screwdriver and then remove the two bolts
holding the fuse. Be careful not to remove the two bolts behind the fuse. Then replace
the fuse and tighten the two bolts to hold the fuse. Please also note that the physical
dimension of the fuse will vary, depending if it is a fuse for the Booster itself or a fuse
that is installed inside the clamp.

B. ON/OFF SWITCH
If your Start Booster is equipped with an ON/OFF Switch, please read the following.
Different types of switches:
- On the Booster itself.
- Inside the handle of the negative (black) clamp.
On the unit itself, please just turn it OFF or ON according to the labels on the switch.
Inside the clamp, push the clip upwards to turn it ON and downwards to turn it OFF.
There is a sign on the handle as well to remind you. See the image below. Always
have your device turned OFF when not in use or when connecting your clamps to your
vehicle or battery. Only turn it ON after you made sure the clamps are properly con-
nected to the vehicle. Once the vehicle has started please remove the Negative clamp
first, then turn your ON/OFF switch OFF and then the positive clamp.

- DOWN position is OFF
C. REVERSE POLARITY ALARM
The reverse polarity alarm, or Buzzer, will emit a sound and a light when it detects a
reverse polarity.It can only work with an ON/OFF switch located on the Booster or on
a 12/24V model. To make sure it is used properly, always have the booster turned OFF
or disconnected before use. Then connect the clamps to the vehicle’s terminals or
battery and at this moment the alarm will emit a noise and light if it detects a reverse
polarity connection. If the clamps are properly connected, nothing will happen. In this
case, you can then turn your unit ON, or select the proper voltage on a 12/24V model
before jump starting your vehicle.

D. 12/24V CONNECTOR / SWITCH
The 12/24V models are either equipped with a Switch or with a Red Connector. In both cases the
unit can be turned OFF, by either placing the switch in the center (position OFF), or by pulling the
red connector out (please make sure not to pull on the cables but only on the connector handle).
Then to select the proper voltage, please refer to the battery of the vehicle (by reading the user
manual of the vehicle itself). Once you have made sure of the voltage, either turn the switch on
12V or 24V, or plug the red connector on the side of the 12V or the side of the 24V. It is important to
select the correct voltage to avoid damaging the vehicle, or Booster and to void any explosion due
to over charge.
Before turning it ON, make sure that the clamps are properly connected and that there is no re-
verse polarity. Then turn the Booster ON to jump start the vehicle. Once the vehicle has started,
please remove first the negative clamp, then turn the Booster OFF and then remove the positive
clamp.
E. CHARGE STATUS
Different models will have different charge status. These voltmeters are here to let you know if
your Start Booster is charged or not. There are different types of voltage indicators:
- LED Voltmeter: composed of 5 LED lights going from Red to Orange to Green. This method is
easy to understand whether your unit is charged or not. When 4 LED lights are ON, it means that
your unit is ready for use. The 5th LED light will only turn ON when your device is connected to a
charger (and is fully charged), or when your device is connected to a working alternator. After you
started your vehicle, leave your Booster connected to the alternator for 10 seconds maximum. If
the 5th Green LED light does not turn ON, it means that your alternator is not working properly.
- Digital/Analog Voltmeter: These two voltmeters will only indicate the voltage of the Booster. If
your Booster is below 12.7V, you need to recharge it. When you leave your Booster connected on
the vehicle for 10 seconds maximum, the voltmeter should read the voltage output of the alterna-
tor, which will let you know if the alternator is working properly or not. (a working alternator has
an output of approximately 14V).
F. CHARGING METHODS
There are different types of chargers available for the Start Boosters:
Automatic Chargers:
This series is called the LESA series. It comes in 12V or 24V. This series is fully automatic, which
means that it will not overcharge your Booster.
LESA1 Car Charger:
This Charging cord is designed only for Start Boosters with batteries. It is meant to recharge your
Booster from the cigar socket of your vehicle whilst driving. Make sure to disconnect it when the
vehicle is not turned ON, to avoid discharging the battery.
Smart Chargers:
It is also a full series of chargers in 6V, 12V and 24V. When the charger is plugged inside the sock-
et or connected to the clamps directly, please press the ‘snow flake’ (AGM) mode on the charger
to start the charge. Make sure to select the correct voltage according to the vehicle or battery.
