2 Safety instructions

2.1 General safety instructions

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.

2.2 Machine-related safety instructions

General safety instructions for sanding:

a. This power tool is designed to be sander with sandpaper. Read all safety instructions, information, illustrations and technical data enclosed with the machine. If the following instructions are not observed, this may lead to electrical shock, fire and/or serious injuries.
b. This power tool is not suitable for coarse sanding, sanding with a wire brush, abrasive cutting or polishing. Applications for which the power

tool is not intended can pose a serious risk and cause injuries.

c. Do not use any accessories that the manufacturer has not specially designed or recommended for this power tool. Just because you can attach accessories to your power tool does not guarantee that they can be used safely.
d. The permissible speed of the insertion tool must be at least the maximum speed specified on the tool itself. Accessories that rotate faster than the permitted speed can break and fly off.
e. The outer diameter and thickness of the insertion tool must correspond to the dimensions of your power tool. Insertion tools which are measured incorrectly cannot be sufficiently shielded or controlled.
f. Sanding discs, flanges, sanding pads and other accessories must be fully compatible with the rotary spindle on your power tool. Insertion tools which are not fully compatible with the rotary spindle on the power tool will rotate unevenly, vibrate strongly and may lead to a loss of control.
g. Do not use insertion tools that are damaged. Before each use, check insertion tools such as sanding discs for chipping and cracks and sanding pads for cracks, wear or heavy abrasive wear. If the power tool or insertion tool is dropped, check whether it is damaged. Damaged insertion tools will generally break after a short time.
h. Make sure that any other persons in the vicinity are at a safe distance from your work area. Anyone entering the work area must wear personal protective equipment. Fragments of the workpiece may fly off and even cause injuries outside the immediate work area.
i. Keep the mains cable away from rotating insertion tools. If you lose control of the machine, the mains cable may be severed or caught and your hand or arm could get caught in the rotating insertion tool.
j. Never place the power tool down before the insertion tool has come to a complete halt. The rotating insertion tool may make contact with the storage area, which could cause you to lose control of the power tool.
k. Do not leave the power tool running when you are carrying it. Your clothing may accidentally come into contact with and get caught in the rotating insertion tool.
l. Clean the vents in your power tool on a regular basis. The fan draws dust into the housing and a

large accumulation of metal dust may create electrical hazards.

Kickbacks and corresponding safety instructions: A kickback occurs as a result of using the power tool incorrectly or misguidedly. It can be prevented by taking appropriate precautions, as described below.

a. Hold the power tool firmly with both hands and move your body and arms into a position that allows you to intercept the kickback forces. Always use the additional handle, if there is one, so that you have the best possible control over the kickback forces or torque reactions during start-up. The operator can control the kickback and reaction forces by taking suitable precautionary measures.
b. Never place your hands near rotating tools. The power tool may move across your hand event of a kickback.
c. Take particular care when working on corners and sharp edges, for example. Prevent the insertion tool from rebounding away from the workpiece and jamming. The rotating insertion tool tends to get jammed when working on corners and sharp edges, or if it rebounds in the process. This results in loss of control or kickbacks.

Special safety instructions for sanding

a. Do not use oversized sanding discs. Follow Festool's specifications when selecting sanding discs. A sanding disc that is too large and protrudes over the sanding pad represents a cutting injury hazard and can cause catching, disc breakage or kickback.

Further safety instructions

- Harmful/toxic dust can be produced during your work (e.g. lead-containing paint, some types of wood and metal). Contact with this dust, especially inhaling it, can represent a hazard for operating personnel or persons in the vicinity. Comply with the safety regulations that apply in your country. Connect the electric power tool to a suitable extraction system.

To protect your health, wear a P2 protective mask.

Always wear protective goggles to protect against sanding hazards.

-If potentially explosive or self-igniting dust is produced during sanding, the machining instructions issued by the material manufacturer must always be followed.

• Attention: Risk of fire! Avoid overheating the grinding material and the sander. Always empty the dust container before taking a break. Swarf in the filter bag or filter of the mobile dust extractor may self-ignite in unfavourable conditions such as flying sparks when grinding metals. Particular danger exists if the swarf is mixed with paint, polyurethane residue or other chemical materials and the grinding material is hot after long periods of work.
• Hold the power tool firmly with both hands and assume a stable stance when performing work. Using both hands ensures that the power tool is guided safely.
• Always use an antistatic suction hose with the power tool. A slight electric shock may cause you to panic briefly and become distracted, which may result in an accident.
• Always use original Festool sanding pads. Foreign pads are not suitable for the speed of the sander and may break.
• Keep the carry bag out of reach of children. Children may suffocate or be strangled when playing with the carry bag.
• Only for AS/NZS: The tool shall always be supplied via residual current device with a rated residual current of 30 mA or less.

2.3 Emission levels

WARNING

Risk of injury, electric shock

▶ Always pull the mains plug out of the socket before performing any type of work on the machine!

7.1 Electronics

The power tool is equipped with a brushless EC-TEC motor for a long service life and power electronics with the following properties:

Smooth start-up

The electronically controlled smooth start-up ensures that the machine starts up jolt-free.

Constant speed

The preselected motor speed is kept constant through electronic control to ensure a uniform sanding speed up to a certain load.

Overload protection

If the pressure becomes too high while working, the power of the machine will be automatically reduced to prevent overheating.

Speed control

You can regulate the speed steplessly within the speed range using the adjusting wheel [1-7] (see Technical data).

This enables you to optimise the sanding speed to suit the material you are working on.

Overheating protection

Overheating protection is triggered when the pressure is too high or the cool air openings are dirty. The power tool beeps three times and switches off. Let the power tool cool down for approx. 15 minutes before using it again.

7.2 Replacing the sanding pad [5]

Observe the following instructions:

• An optimal work result can only be achieved using original accessories and consumables. The use of non-original accessories or consumables invalidates the right to claim under warranty.
• Only fit and remove the sanding pads using the tool supplied.
• Make sure that both flat edges engage in the opening on the sanding pad.

7.3 Changing the sanding discs [6]

Compatible StickFix sanding discs are quick and easy to attach to the StickFix sanding pad.

CAUTION! The holes in the sanding disc must be aligned with the holes in the sanding pad. Otherwise, the suction power is impaired and there is more exposure to dust.

Do not use interface pads.

7.4 Sanding close to edges [7]

The removable brush segment means that the distance at the side between the wall/ceiling and the sanding pad is reduced.

CAUTION! Without a brush segment, there is more exposure to dust: Only remove it for specific applications.

The brush segment is fitted in reverse order to the process for removing it.

7.5 Dust extraction

WARNING

Heath hazard posed by dust

▶ Always work with an extractor.
▶ Comply with national regulations.
▶ Wear a dust mask.

A Festool mobile dust extractor with an extractor hose diameter of 27 mm or 36 mm (36 mm recommended due to the reduced risk of clogging) can be connected to the extractor connector [1-4].

① Festool CTL/M 36 E ACP L A N E X mobile dust extractors are adapted to the quantity of dust generated and permanently ensure the necessary suction power.

Recommendation: Use an antistatic suction hose. This helps reduce the electric charge.

8 Working with the power tool

WARNING

Risk of injury

▶ Do not hold the power tool by the sanding head.
▶Hold the power tool with both hands using the gripping surfaces [1-10].

▶ To switch on the power tool, see Section 6.
▶ Carefully place the sanding head onto the sanding surface.
▶ Perform the sanding work.

Do not apply too much pressure on the power tool as this will cause overloading. The best sanding results are achieved with moderate application pressure. The sanding performance and quality depend mainly on selecting the correct abrasive.

After finishing work

▶ Once you have finished the sanding work, set the power tool down.

CAUTION! Do not set the power tool down with the sanding head facing downwards – always lay it on the floor so that it is on its side with the brush ring facing down. Otherwise the sanding pad could be deformed.

GB LHS-E 225

To protect the sanding pad and the sanding head, always transport and store the power tool in the accompanying carry bag without the sanding discs.
