WARNING
Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference. Do not use this power tool before you have thoroughly read and completely understood this Instruction Manual and the enclosed “General Safety Instructions” (document number 3 41 30 465 06 0). The documents mentioned should be kept for later use and enclosed with the power tool, should it be passed on or sold. Please also observe the relevant national industrial safety regulations.
Intended use of the power tool:
Hand-guided oscillator for sanding small surfaces, corners and edges, for sawing thin parts of steel sheet, wood and plastic, for scraping, polishing, rasping, cutting and separating without water in weather-protected environments, using the application tools and accessories recommended by FEIN.
Special safety instructions.
Hold power tool by insulated gripping surfaces only, because the cutting tool could cut into the machine’s power cord. Contact with a “live” wire make exposed metal parts of tool “live” and shock the operator.
Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
Do not use accessories which are not specifically designed and recommended by the power tool manufacturer. Safe operation is not ensured merely because an accessory fits
your power tool.
Grasp the power tool in such a safe manner that your body never comes into contact with the application tool, especially while working with application tools such as saw blades or other blades pointed toward the grasping range. Touching sharp tips or cutting edges can lead to injuries.
Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. Where appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss. Do not direct the power tool against yourself, other persons or animals. Danger of injury from sharp or hot application tools.
Do not rivet or screw any name-plates or signs onto the power tool. If the insulation is damaged, protection against an electric shock will be ineffective. Adhesive labels are recommended.
Clean the ventilation openings on the power tool at regular intervals using non-metal tools. The blower of the motor draws dust into the housing. An excessive accumulation of metallic dust can cause an electrical hazard.
After working gypsum-containing materials: Blow out the ventilation openings of the power tool and the switch element with dry and oil-free compressed air. Otherwise, gypsum-containing dust can settle in the power tool housing and switch element, which can harden in connection with humidity. This can impair the switching mechanism. Use and handling of the battery (battery pack).
To avoid hazardous situations such as burns, fire, explosion, skin injuries, and other injuries when handling the battery, observe the following instructions : Batteries must not be disassembled, opened or reduced in size. Do not subject batteries to mechanical impact or shock. Hazardous vapours and fluid can escape in case of damage and improper use of the battery. The vapours can irritate the respiratory system. Liquid ejected from the battery may cause skin irritations or burns.
When battery fluid from a damaged battery has come into contact with objects close by, check the respective components, clean them or replace them as required. Keep the battery away from heat and fire. Do not store the battery in direct sunlight. Do not remove the battery from its original packaging until it is going to be used.
Before any work on the machine itself, remove the battery from the power tool. If the power tool accidentally starts, there is danger of injury.
Remove the battery only when the power tool is switched off.
Keep the battery away from children.
Keep the battery clean and protect it against moisture and water. Clean contaminated battery terminals and power tool connections with a dry, clean cloth.
Use only intact original FEIN batteries that are intended for your power tool. When working with and charging incorrect, damaged, repaired or reconditioned batteries, imitations or other brands, there is danger of fire and/or explosion.
Follow the safety warnings in the operating instructions of the battery charger.
Handling hazardous dusts
For work procedures with this power tool where material is removed, dusts develop that can be hazardous to one’s health.
Contact with or inhaling some dust types, e. g. asbestos and asbestos- containing materials, lead-containing coatings, metal, some wood types, minerals, silicate particles from materials containing stone, paint solvents, wood preservatives, antifouling paints for vessels, can trigger allergic reactions to the operator or bystanders and/or lead to respiratory infections, cancer, birth defects or other reproductive harm. The risk from inhaling dusts depends on the exposition. Use dust extraction matched appropriately for the developing dust, as well as personal protective equipment and provide for good ventilation of the workplace. Leave the processing of asbestos-containing materials to specialists.
Wood and light-metal dust, hot mixtures of grinding dust and chemical materials can self-ignite under unfavourable conditions or cause an explosion. Avoid sparking in the direction of the dust collector as well as overheating of the power tool and the materials being sanded, empty the dust collector/container in time, observe the material manufacturer’s working instructions, as well as the relevant regulations in your country for the materials being worked.
Hand/arm vibrations
The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool. However, if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Operating Instructions.

Do not use accessories not specifically intended and recommended for this power tool by FEIN. The use of non-original FEIN accessories can lead to overheating of the power tool and destroy it.
Possible overloading of the vibration damping with especially heavy accessories!
When using the large round sanding plate
(No. 63806195210, Ø115 mm) or the cleaning kit for tilejoints (No. 63719011220), the damping system can be subject to overload due to the heavy weight of the accessories. This becomes apparent through unpleasant and very intense vibration of the machine. Corrective action: Reduce the speed of the machine to electronic level 2.
Due to the then possibly reduced working progress, the machine is only suitable to a limited extent for above mentioned accessories.
  Guide the power tool toward the work piece only when switched on.
The application tool can be offset in 30° steps and fastened in the most favourable working position.
Changing the tool (see pages 5/6).
Do not switch the power tool on while the clamping lever is open. Otherwise there is danger of crushes or contusions to the hand and fingers.
Do not actuate the clamping lever while the power tool is running. Otherwise there is danger of injury.
Do not reach into the area of the clamping jaws. Otherwise there is danger of crushes or contusions to the fingers.
Do not operate the power tool with with open clamping jaws and without an application tool! This could damage the power tool.
When the clamping jaws are open before the application tool is inserted, pivot the clamping lever toward the front and then back again. The clamping jaws are closed now. The application tool can be inserted.

Handling the battery.

Store, operate and charge the battery only using FEIN battery chargers within the battery operating-temperature range between 5 °C – 45 °C (41 °F – 113 °F). At the beginning of the charging procedure, the battery temperature must be within the battery operating-temperature range.

the battery operating temperature range, then charge

The real percentage of the battery charge condition is only indicated when the power tool motor is stopped. The electronics automatically switch off the motor prior to the battery being deep discharged.
Notes on sanding.
Press the power tool with the sanding sheet briefly and firmly against a flat surface and briefly switch the power tool on. This provides for good adhesion and prevents premature wear.
When only one tip or corner of the sanding sheet is worn, it can be removed again and reattached turned by 120°.
Work with the entire surface of the sanding plate, not only with the edge or tip.
When sanding with small triangle sanding plates, select a high oscillating frequency (electronics level 4 – 6); when sanding with the round sanding plate and the large triangle sanding plate, select a moderate oscillating frequency (max. electronics level 4).
Sand with continuous motion applying moderate pressure. Applying excessive pressure does not increase the rate of removal, it only wears off the sanding sheet faster.
Notes on sawing.
Select a high oscillating frequency. Round saw blades can be released and clamped offset again, to allow for uniform wearing off. Notes on scraping. Select a moderate to high oscillating frequency.
Repair and customer service.
When working metal under extreme operating conditions, it is possible for conductive dust to settle in the interior of the power tool. Blow out the interior of the power tool via the ventilation slots frequently with dry and oil-free compressed air.
When working gypsum-containing materials, dust can settle within the power tool and switch element, which can harden in connection with humidity. This can impair the switching mechanism. Blow out the interior of the power tool via the ventilation slots and the switch element frequently with dry and oil- free compressed air.
For storage of the power tool, remove the application tool, shut the clamping lever, and then press in the fastening element.
