General power tool safety warnings
WARNING! Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. Follow the operating manual for the charger and the battery pack.

Machine-specific safety notices

Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by hand or against your body leaves it unstable and may lead to loss of control.
Festool electric power tools must only be installed on work tables provided by Festool for this purpose. If the tool is installed in another, or self-made, work table, it can become unstable and result in serious accidents.
Wait until the power tool has come to a complete halt before placing it down. The insertion tool can get caught and lead to a loss of control of the power tool.
Deformed or cracked saw blades and saw blades with blunt or broken cutting edges must not be used.
The saw blade on the jigsaw must always be running when it makes contact with the workpiece.
Wear suitable personal protective equipment: Ear protection, protective goggles, dust mask for work that generates dust, protective gloves for working with rough materials and for changing tools.
Harmful/poisonous dust may be produced when working (e.g. paint products containing lead and some types of wood). Contact with or inhalation of this dust may pose a risk for the operating personnel or persons in the vicinity. Comply with the safety regulations that apply in your country. Connect the power tool to a suitable dust extractor.
Always connect the machine to a dust extractor when performing work that generates dust.
Stroboscopic light can cause epileptic seizures. Do not use this machine if you are susceptible to epileptic seizures.
Do not look into the stroboscope light. Looking into the light source can damage your vision.
Do not use power supply units or third-party battery packs to operate cordless power tools. Do not use third-party chargers to charge the battery packs. The use of accessories not expressly authorised by the manufacturer can result in electric shocks and/or serious accidents.

WARNING Risk of injury, electric shock

Always disconnect the battery packs from the machine before performing any type of work on the machine!

Changing tools
CAUTION
Risk of injury from hot and sharp insertion\tool

Do not use any blunt or faulty insertion tools.
Wear protective gloves when handling an insertion tool.

Selecting the saw blade

Only use saw blades with a T-shank. The saw blade should not be longer than that required 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 angle tables and base adapters. We recommend the S 105/4 FSG Festool saw blade. Festool saw blades for jigsaws are colour-coded. The colour represents the material for which the saw blade is suited.

Colour Material
Yellow Wood
Red Plastics
Green Building materials
Blue Metal

More information can be found on the packaging, in your Festool catalogue or at www.festool.co.uk.

Inserting the saw blade

Always disconnect the power tool from the power supply before changing blades.

If necessary, lift up the chip guard [3-1].
Slide the saw blade [3-4] into the opening [3-2] as far as the stop with its teeth in the cutting direction.
Turn the saw blade [3-4] clockwise by approx. 30° until it engages. Check that the saw blade is secure. A loose saw blade can fall out and cause an injury.
If the saw blade is very short, it is advisable to remove the saw table (see section 8.4) before inserting the saw blade.

Adjust the saw blade guide after every saw blade change

The saw blade guide was designed to improve guidance of the saw blade.

Remove the saw table (see section 8.4).
Tighten the screw [3-6] using the hex key [3-5] until the jaws are almost touching the saw blade.

NOTICE

Damage to the machine or saw blade

Do not tighten the screw [3-6] too much. It must be possible to move the saw blade slightly.
Ejecting the saw blade
When ejecting the saw blade, hold the power tool such that no persons or animals can be injured.
Push the saw blade ejection [3-3] forwards as far as the stop. Saw blade ist thrust out mechanically.
A tool change is only possible when the tool holder is located in the upper position.
When changing the saw blade is not possible: Let the jigsaw run at a high speed for 3–10 seconds. Actuate the saw blade ejection [3-3] again.

Using the chip guard
The chip guard [3-1] prevents chips from flying away and improves the efficiency of the chip extraction system.

Apply slight pressure to push the chip guard [3-1] downwards.

Inserting the splinterguard

The splinterguard prevents the edges of the material from splintering during the cut, even at the end where the saw blade exits the material.

Switch off the machine and slide the splinterguard [4-1] onto the guide [4-2] and up to the saw blade.
Switch on the jigsaw.
On a level surface, slide in the splinterguard (not using your hand!) while the machine is operating until it is flush with the front edge of the saw table (speed setting 5). This cuts into the splinter guard.
When it is worn, push the splinterguard approx. 3 mm further to the rear and continue using it.
To guarantee reliable operation of the splinterguard, it must seal tightly on both sides of the saw blade. A new splinterguard should therefore be fitted after every saw blade change to guarantee splinter-free cuts.

Changing the saw table

Open the change lever [1-9].
Remove the saw table downwards.
Assembly is performed in reverse sequence to removal. Ensure that the saw table is firmly seated in the guide. Instead of the saw table, the WT-PS 400 angle table or ADT-PS 400 base adapter can be installed at the support. Never saw without the saw table, or one of the other tables or adapters offered in the Festool accessories range.

Extraction
WARNING
Health risk due to dust

Always work with an extractor.
Comply with national regulations. The extraction adapter [5-3] allows jigsaws to be connected to a dust extractor (hose diameter 27 mm).
Insert the extraction adapter in the rear opening of the saw table so that the hook [5-2] engages in the recess [5-1].
To remove the extraction adapter, press the hook [5-2]. Due to the low power consumption of the machine (low energy consumption), dust extractors with an automatic switch-on function will sometimes only start up when the actual cut is made.
Set the dust extractor to continuous operation for special applications (e.g. low stroke rate, soft wood).

Adjusting the pendulum stroke

In order to saw different materials with the proper rate of advance the pendulum stroke can be adjusted. Set the required stroke via the pendulum stroke switch [1-12]: Position 0 = pendulum stroke disabled Position 3 = maximum pendulum stroke

Recommended pendulum stroke setting

Softwood, chip board, wood fibreboard 1 – 3
Blockboard, plywood, plastic 1 – 2
Ceramics 0
Aluminium, non-ferrous metals 0 – 2
Steel, hardwood 0 – 1

Stroke rate control

Using the adjusting wheel [1-6], the stroke rate can be continuously adjusted between 1500 and 3800 rpm (PSBC 420 EB: 1000–3800 rpm). This enables you to optimise the cutting speed to suit the respective material. Automatic load detection is activated in position
A : The stroke rate drops when idling and is adjusted to the highest setting when the workpiece is introduced. Recommended stroke rate (position of the adjusting wheel)

Hard and soft wood, blockboard, plywood, chipboard A
Fibreboard 4–A
Plastic 3–A
Ceramic, aluminium, non-ferrous metals 3–5
Steel 2–4

Working with the electric power tool

CAUTION
Materials which produce a lot of dust Damage to the machine due to the ingress of dust, risk of injury

Do not work overhead. When working on small or thin workpieces, always use a stable base, or the CMS module (accessory).

When working, hold the electric power tool by the handle and guide it along the desired cutting line. For precise cuts and smooth running, use two hands to guide the electric power tool.

9.1 Free saw guidance along a scribe mark
The triangular pointer on the splinterguard
[4-1] indicates the cutting line of the saw blade. This facilitates sawing along a scribe mark.

Lighting
WARNING
Stroboscopic light could lead to misjudgement of the saw blade position
Risk of injury

Ensure the work area is well illuminated. A steady light or stroboscopic light is installed to illuminate the cutting line: Up to approx. 2100 rpm: Steady light From approx. 2100 rpm upwards: Stroboscopic light In the overhead position (+/- 45°), the lighting is switched off completely. If required, you can adjust the lighting:
