Introduction
Thank you for purchasing this quality product.
To minimize the risk of injury we urge that our cli-
ents take some basic safety precautions when using this device. Please read the operation in-
structions carefully and make sure you have understood its content.
Keep these operation instructions safe.
Notes
Switch the jump starter off before connecting the connection cables to the battery to avoid
dangerous sparking from developing.
Before removing the battery clamps from the battery, switch the device off.
As explosive gasses might be created during the charging process, fire and sparking, etc.
needs to be avoided.
The red battery clamp is connected to the positive terminal and the black clamp to the negat-
ive terminal –
NEVER
switch them around!
NEVER
use the jump starter if the charging cables or clamps are damaged. Do not shake or
push against the cables when charging.
NEVER
try to charge a frozen battery!
Only use the fuse delivered in this device –
NEVER
exchange it for a bigger one!
Before charging the battery, please clean it and check the battery voltage.
Please note that the attached battery needs at least 50 Ah and may not exceed 750 Ah
(Booster 430) or 800 Ah (Booster 630).
Safe Handling of Batteries
When handling the battery, it is important to wear protective glasses and gloves. Contact of
skin, eyes or clothing with the battery acid needs to be avoided at all times, as it is extremely
corrosive. If battery acid gets into the eyes, they need to be rinsed out immediately with a lot
of water. Consult a doctor immediately after rinsing your eyes out. Acid splashes on the skin
need to be immediately washed off with water and soap. On clothing, the acid can cause
holes.
Do not place the battery charger on flammable undergrounds whilst charging. The device
warms up during its use. Place the device in such way as to be able to cool down and to have
enough airflow. Never cover the airing holes.
The charger device is only allowed to be used indoors. The device needs to be kept away
from moisture and humidity. If the device should get wet, there is a danger of being electro-
cuted.
When the battery is charged, small amounts of gas are released from the battery acid, which
is normal. The gas leak is noticeable through the formation of bubbles.
Attention!
Bursting
gas bubbles cause acid splashes in the vicinity of the battery! It is essential that you follow the
instructions for connecting the device, otherwise sparks can arise that will cause the gases
(oxyhydrogen!) to explode. The device must also not be operated in the area of open flames.
Never smoke when handling the battery! It is essential to ensure that there is good ventilation
as the gas is explosive.
Please note:
Only charge common 12 or 24 volt lead-acid batteries. Do not charge batteries
which are not rechargeable. Only intact batteries can be charged. The charging duration de-
pends on the level of charge of the battery. The level can be determined by measuring the
density of acid with a common battery hydrometer. If you have a permanently sealed, main-
tenance-free battery, it may not be opened. With this type of battery, it is not required and pos-
sible to check the acid or correct it. To be able to charge the battery, all closure caps of the
battery cells which can be removed should be taken off (see fig.). The acid level should then –
if required – be checked. The acid level for an empty battery should be 0.5–1 cm above the
lead strip in the battery cells. If this is not the case, distilled water needs to be refilled. Under
no circumstances tap water can be used. As the state of charge increases, the level of acid
rises. To ensure that the battery will not overflow, the acid may not be filled up to the max-
imum marking. The lids are only allowed to be placed on the battery again after the charging
