The emission values specified (vibration, noise) were measured in ac-

cordance with the test conditions stipulated in EN 62481 and are intend-

ed for machine comparisons. They are also used for making preliminary 

estimates regarding vibration and noise loads during operation.
The emission values specified refer to the main applications for which 

the power tool is used. If the electric power tool is used for other ap-

plications, with other tools or is not maintained sufficiently prior to 

operation, however, the vibration and noise load may be higher when 

the tool is used.
Take into account any machine idling times and downtimes to estimate 

these values more accurately for a specified time period. This may signif-

icantly reduce the load during the machine operating period.

Use

The machine is designed for cutting and making cut-outs in wood, plas-

tic, steel, non-ferrous metals, aluminium and ceramics. It is suited for 

straight and curved cuts with a bevel angle of ±45°. To carry out the 

operations described below, use saw blades recommended by the man-

ufacturer.
 The user bears full responsibility for the consequences of using the ma-

chine for purposes not specified here.

Accumulator Charging Instructions

1.  Please make sure the mains voltage is the same as the voltage list-

ed on the charger’s machine plate. Connect the charger (N1) to a 

power source. A red LED indicator (N2) will light up. This means the 

charger is ready to charge. If the red LED indicator does not light up, 

check the connection to power supply. If the power supply func-

tioning correctly, bring the charger in for repair to an authorised 

service centre!

2.  Slide the accumulator (B1) all the way into the charger.
3.  The red LED will light up and the green LED (N2) will start flashing 

to indicate that the accumulator is charging.

4.  After approximately 60 minutes, the accumulator should be fully 

charged, indicated by the green and red LED staying lit without 

flashing.

5.  Remove the accumulator from the charger. If you do not wish to 

charge another accumulator, disconnect the charger from the pow-

er source.

New batteries:

Battery capacity may be slightly smaller than the listed value during the 

first few initial charge cycles. The reason is that the chemical composi-

tion of the batteries has not been activated yet. This is a temporary issue 

and will resolve on its own after a few charge cycles.

Note:

•  A blinking green indicator means that the battery is fully charged or 

that it is in slow charge mode, which maintains a low charge level of 

the battery.

•  The initial battery charge may take longer then 60 minutes (accord-

ing to battery capacity) depending on the environment tempera-

ture, the power supply and the current charge level.

•  If you are not using the charger, please unplug it from the power 

source.

Important information about the charging 

process:

1.  To get the best out of the batteries in terms of longevity and per-

formance is to charge them at an ambient temperature of 18  °C 

to  24  °C. 

DO  NOT CHARGE

 the batteries at temperatures below 

0 °C and above 45 °C. This is very important. You will prevent serious 

battery damage.

•  Do not charge the batteries in direct sunlight, especially in the sum-

mer! You will prevent extreme overheating, which could damage 

them!

2.  If a battery that is too cold (below 0 °C) is inserted into the charg-

er, the charger will not begin charging it right away; instead, the 

green and the red indicator light will begin blinking. Once the bat-

tery reaches the right temperature naturally (within the standard 

range), the fast charge process will begin automatically.

•  If a battery that is too hot (more than 45 °C), is inserted into the 

charger, the charger will not begin charging it right away; instead, 

the green and the red indicator light will begin blinking. Once the 

battery reaches the right temperature (within the standard range), 

the fast charge process will begin automatically.

3.  If it is not possible to charge the batteries properly (the red indica-

tor is blinking):

•  Check that the battery contact surfaces are not dirty. Clean them 

with a cotton wad and alcohol as needed.

•  If the battery is still not charging properly, send or bring the charger 

(including the batteries) to your nearest authorised service centre.

4.  Under certain conditions and if the charger is connected to power, 

foreign material may short circuit the charge contacts inside the 

charger. Foreign conducting substances, such as steel fibres, alumini-

um foils or metal deposits must be removed from the charger contin-

uously. Always unplug the charger from power prior to cleaning.

5.  If you are carrying out several different charge operations one after 

the other, the charger may become hot. This is normal and is not 

a sign of a technical problem.

6.  Prevent liquid from getting inside the charger as it could cause an 

electrical injury. Do not place the battery in a hot environment if 

you wish to facilitate the battery cool down process.

7.  Accumulator batteries can remain plugged into the charger with-

out a  risk of damage to them or the charger itself. The batteries 

will remain fully charged in the charger. 

DO NOT LEAVE

 charged 

batteries in the charger if the charger is not plugged into the power 

outlet.

8. 

DO NOT USE ACCUMULATOR BATTERIES

 if they are damaged or if 

liquid leaks out of the cells. If the battery liquid comes into contact 

with your skin, immediately flush the area with water and monitor 

the skin’s reaction. Seek medical attention if needed. If it comes into 

contact with your eyes, flush them with lots of water and immedi-

ately seek medical attention.

9.  If you are charging a fully discharged battery or if you stop charging 

the battery before it is fully charged, you must count each of these 

cycles as an entire charging cycle.

Note on Lithium-ion (Li-Ion) batteries

•  These types of batteries do  not have a  memory effect, in other 

words, the batteries can be charged at any state of discharge. If you 

take the batteries out of the charger prior to fully charging them, it 

will not damage them.

•  Each Li-Ion battery is equipped with deep discharge protection. If 

the voltage falls (due to overloading or discharge) below the mon-

itored range, the electronic circuit will disconnect the cells. The 

machine will then either work intermittently or not at all. You must 

reduce machine load or recharge the battery.

Storing lithium-ion batteries

•  Store fully charge batteries in a dry and dust-free environment at an 

ambient temperature between 5 °C and 40 °C. If you are not using 

the batteries for a longer period of time, we recommend you charge 

them fully once every three months.

•  Keep the battery contacts clean. Do not store the replacement bat-

tery together with metal items as it may cause a short circuit.

•  It is always necessary to charge batteries that were not used for 

a long time prior to use.
