WARNING
Risk of injury, electric shock

Always disconnect the battery pack before any
type of work on the machine!
7.1 Changing tools
CAUTION
Hot and sharp tools
Risk of injury

Wear protective gloves.
Selecting saw blade
Only use saw blades with a T-shank. The
saw blade should not be longer than that re-
quired for the intended cut. To ensure safe
guidance, during the cut the saw blade should
emerge at the bottom of the workpiece at every
point.
 Only use cross-set saw blades when using the
angle and adapter table. We recommend Fes-
tool saw blade S 105/4 FSG.
Inserting saw blade
Always disconnect the battery pack from the
machine before every tool change!

If necessary, lift up the chip guard [4-1].

Slide the saw blade [4-4] into the opening [4-2]
as far as the stop with its teeth in the cutting di-
rection.

Turn the saw blade [4-4] clockwise approx. 30°.
Check that the saw blade is secure. A loose
saw blade can fall out and cause an injury.
If the saw blade is very small, it is advis-
able to remove the saw base (see chapter 7.4)
before inserting the saw blade.
Adjust the saw blade guide after every saw blade
change:
The saw blade guide was designed to improve guid-
ance of the saw blade.

Remove the saw base (see chapter 7.4).

Tighten the screw [4-6] using the Allen key [4-
5] until the jaws are almost touching the saw
blade.
NOTE
Damage to the machine or saw blade

Do not tighten the screw [4-6] too firmly! It must
be possible to move the saw blade slightly.
Ejecting saw blade
 When ejecting the saw blade, hold the electric
power tool such that no persons or animals can
be injured.

Push the saw blade ejection [4-3] forwards as
far as the stop.
 A tool change is only possible when the tool
holder is located in the upper position!
If the saw blade is stuck and cannot be changed:
Operate the jigsaw at high speed for 3 - 10 seconds.
Actuate the saw blade ejection [4-3]again.
7.2 Using the chip guard
The chip guard [4-1] prevents chips flying away and
improves the efficiency of the chip extraction sys-
tem.

Using minimal pressure, push the chip guard
[4-1] downwards.
