WSF 900

Application:

The VARILEX® WSF 900 Duo

...used as a high torque angle grinder for flap discs up to 115 mm in diameter, the FIX Hook & Loop system and
with the adapter for the MINI-FIX Hook & Loop system

...used as a linear grinder. The expansion roller simply screws to allow 50 mm grinding sleeves
to be used (Art.-No. 65210)

…with grinding belt roller for working on pipes (Art.-No. 65215)

…with holder for use as a stationary grinder (accessory) (Art.-No. 10009)

Putting too much weight on the machine will damage the angle grinder and increase the discs’ wear; grinding
performance will suffer.

Never use a cutting disc for grinding. The cutting disc must have a proper cutting edge. When separating stone, a
guide is advised!

For surface grinding use a plastic grinding disc with abrasive paper.
For removal of rust or old paint coats, we recommend to use a steel brush (saucepan brush).

This angle grinder can be used for separating and grinding many different materials, e.g. metal or stone.
In case of doubt please read the manufacturer’s instructions. Do not use this product in any other way as
stated for normal use.

Connect only to a single-phase AC current supply and only to the mains voltage specified on the rating
plate. Connection to sockets without earth protection is possible as the appliance features protective
regulation to DIN 57740/VDE 0740 and CEE 20. Radio suppression complies with the European standard
EN 55014. When fitting the plug, make sure that the brown (live) wire of this appliance is connected to
the plug terminal marked L or coloured red, and the blue (neutral) wire of this appliance is connected to
the plug terminal marked N or coloured black. Under no circumstances must the wires of this appliance
be connected to the earth terminal of the plug marked either E, with the earth symbol, or coloured green
or green/yellow.

The electronic smooth start will prolong the life of both the motor and the gears.

Switching on: Push the sliding switch forward. To lock, depress the front part of the switch. Switching off:
To unlock, depress the back part of the sliding switch. The switch will automatically move back to "0".

The number of revs is adjusted electronically when the load increases.
In case of a longer overload period the speed is decreased electronically. The machine continues to run
slowly to cool down the motor coil. After switching off and on the machine can be used at rated load. The
duration of cooling-down period depends on the grade of overload.

The new ‘Quick-Lock’ cable system allows a quick change of machines (e. g. PTX - 800).

Safety advice:

 Please pay attention to the safety instructions in the attached leaflet!
 Do not pierce the motor housing as this could damage the double insulation (use adhesives).
 Always pull the plug from the mains before making any settings or carrying out maintenance.
 Only plug-in when machine is switched off.
 Keep mains lead clear from working range of the machine. Always lead the cable away behind you.
 Before use, check the machine, cable, and plug for any damages or material fatigue. Repairs should only be carried out

by authorised service agents.

 After the machine is turned off the machine will not be idle immediately. (After-running of the work spindle.)

Allow the machine to come to a stop before putting down.

 Never reach into the danger area of the machine when it is running.
 Always wear safety goggles and ear protectors when working with this machine. It is further recommended to wear safety gloves, apron, as well as sturdy non-slip

shoes.

 Always use the additional handle.
 Always use the protecting guard when rough grinding and cutting.
 Only use tools whose permitted speed is at least as high as the highest no-load speed of the machine.
 Pay attention to the dimensions of the grinding disc. The mounting hole diameter must fit the mounting flange without play.

Do not use reducer pieces or adapters.

 Check grinding tools before use. The grinding tool must be properly mounted and turn freely.

Perform a test run for at least 30 seconds without load. Do not use damaged or vibrating grinding tools.

 Immediately switch off the machine in case of considerable vibrations or if other malfunctions occur.

Check the machine in order to find out the cause.

 Always use and store the grinding discs according to the manufacturer's instructions.
 When grinding metal, flying sparks are produced. Take care that no persons are endangered. Because of the danger of fire,

no combustible materials should be located in the vicinity (spark flight zone). Do not use dust extraction!

 Always hold the machine in a way that sparks or sanding dust fly in counter direction to your body.
 Dust that arises when working in stones with crystalline silicic acid can damage your health. Do not work on any material containing asbestos. Please note the

safety regulations, VBG, of the employer's liability insurance association.

 Never use a cutting disc for grinding. Do not subject cutting discs to side pressure.
 When separating stone the guide must be used!
 The adjusting nut must be tightened before starting to work with the machine.
 The work piece must be fixed if it is not heavy enough to be steady. Never lead the work piece to the grinding disk with your hand.
 In case of extreme operating conditions (e.g. when smoothing metals with the supporting disk and vulcanised fibre disks) strong contamination can build up inside

the angle grinder.
In such cases it is recommended to shorten the cleaning cycles and/or add a residual current operated device.
