4. Special Safety Instructions

4.1 General Safety Recommendations for grinding, sanding, wire

brushing, polishing and cutting-off operations:

Use

a) This power tool is intended to function as a sander (not PE 15-20 RT) or polisher. 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.
b) Operations such as grinding, sanding, wire brushing or cutting-off are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
c) Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.

d) The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart.

e) The external diameter and thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.

f) Threaded mounting of accessories must match the sanding spindle thread. For accessories mounted by flanges, the arbour hole of the accessory must fit the locating diameter of the flange. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.

g) Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If a power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing the accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.
h) Wear personal protective equipment. Use a face shield, safety goggles or safety goggles depending on the application. As appropriate, wear a dust mask, hearing protectors, gloves and a 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 filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

i) Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of a workpiece or broken accessory may fly away and cause injury beyond the immediate area of operation.

j) Hold the power tool by the insulated gripping surfaces only when performing an operation where the accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and shock the operator.

k) Position the cord clear of the rotating accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the rotating accessory.

I) Never lay the power tool down until the accessory has come to a complete stop. The rotating accessory may grab the surface and pull the power tool out of your control.

m) Do not run the power tool while carrying it at your side. Accidental contact with the rotating accessory could snag your clothing, pulling the accessory into your body.

n) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.

o) Do not operate the power tool near flammable materials. Sparks could ignite these materials.

p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

4.2 Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged sanding wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding.

For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The abrasive wheel may either jump toward or away from the operator, depending on direction of the disc’s movement at the point of pinching. Abrasive wheels may also break under these conditions.

Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided if suitable precautionary measures are taken as described below.

a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use the additional handle, if provided, for maximum control over kickback or a torque reaction during start- up. The operator can control torque reactions or kickback forces if proper precautions are taken.

b) Never place your hand near the rotating accessory. Accessory may kickback over your hand.

c) Do not position your body in the area where the power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the grinding wheel’s movement at the point of snagging.

d) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.

e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.

4.3 Safety Warnings Specific for Sanding Operations (not PE 15-20 RT):

a) Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback.

4.4 Safety Warnings Specific for Polishing Operations:

Do not allow any loose portion of the polishing bonnet or its attachment strings to spin freely. Tuck away or shorten the loose attachment strings. Loose and spinning attachment strings can entangle your fingers or snag on the workpiece.

Caution: The workpiece can heat up during the polishing process!

4.5 Additional safety instructions:

WARNING ­- Always wear protective goggles.
WARNING ­- Always operate with two hands.

Use elastic cushioning layers if they have been supplied with the grinding media and if required.

Observe the specifications of the tool or accessory manufacturer!

Accessories must be stored and handled with care in accordance with the manufacturer’s instructions.

Ensure that accessories are installed in accordance with the manufacturer’s instructions.

The tool continues running after the machine has been switched off.

Do not use separate reducing bushings or adapters to adapt tools with a large hole.

The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be sufficiently supported.

If accessories with threaded inserts are used, the end of the spindle may not touch the base of the hole on the sanding tool. Make sure that the thread in the accessory is long enough to accommodate the full length of the spindle. The thread in the accessory must match the thread on the spindle. See page 3 and chapter 14. Technical Specifications for more information on the spindle length and thread.

Use of a fixed extractor system is recommended. Always install an RCD with a maximum trip current of 30 mA upstream. When the machine is shut down via the GFCI, it must be checked and cleaned. See chapter 9. Cleaning.

When working in dusty conditions, ensure that ventilation openings are not blocked. If it becomes necessary to remove dust, first disconnect the power tool from the mains supply (use non-metallic objects) and avoid damaging internal components.

Damaged, eccentric or vibrating tools must not be used.

Pull the plug out of the socket before making any adjustments, converting or servicing the machine.

A damaged or cracked additional handle must be replaced. Never operate a machine with a defective additional handle.

A damaged or cracked hand guard must be replaced. Never operate a machine with a defective hand guard.

Reducing dust exposure:

****Some of the dust created using this power tool may contain chemicals known to cause cancer, allergic reaction, respiratory disease, birth defects or other reproductive harm. Some of these substances include: lead (in paint containing lead), mineral dust (from bricks, concrete etc.), additives used for wood treatment (chromate, wood preservatives), some wood types (such as oak or beech dust), metals, asbestos.
The risk from exposure to such substances will depend on how long you or people nearby are exposed to them.
Do not let particles enter the body.
Do the following to reduce exposure to these substances: ensure good ventilation of the workplace and wear appropriate protective equipment, such as respirators able to filter microscopically small particles.

Observe the relevant guidelines for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal).
Collect the particles generated at the source, avoid deposits in the surrounding area.
Use suitable accessories for special work. In this way, fewer particles enter the environment in an uncontrolled manner.
Use a suitable extraction unit.
Reduce dust exposure with the following measures:
– do not direct the escaping particles and the exhaust air stream at yourself or nearby persons or on dust deposits.
– use an extraction unit and/or air purifiers.
– ensure good ventilation of the workplace and keep clean using a vacuum cleaner. Sweeping or blowing stirs up dust.
– Vacuum or wash the protective clothing. Do not blow, beat or brush.

8.3 Working directions

Polishing:
At the start of the polishing process, start with the lowest speed, coarse polish and a lambskin or a coarse pad.

Then the speed is increased, a medium polish and a medium pad are used.

A high speed is used for the finish (high gloss polishing), as well as the finest polish and the finest pad.

Polishing is done with crossover polishing, i.e. from left to right and then again from top to bottom. Here make sure not to stay too long in one spot, since the surface can heat up a lot and the surface could get damaged.

Sanding (not PE 15-20 RT):
Press down the machine evenly on the surface and move back and forth so that the surface of the workpiece does not become too hot.

9. Cleaning

It is possible that particles deposit inside the power tool during operation. This impairs the cooling of the power tool. Conductive build-up can impair the protective insulation of the power tool and cause electrical hazards.

The power tool should be cleaned regularly, often and thoroughly through all front and rear air vents using a vacuum cleaner. Prior to this operation, separate the power tool from the power source and wear protective goggles and a dust mask.

Cleaning the dust filter:

If too much dust is deposited on the dust protection filter, the cooling to the motor is reduced and the motor may overheat and become damaged. Clean the dust protection filter regularly, frequently and thoroughly by vacuuming or wiping. Prior to this operation, separate the power tool from the power source or remove the dust protection filter. When working, wear goggles and a dust mask.

10. Troubleshooting

PE 15-25:

The electronic signal indicator (5) lights up and the load speed decreases. There is too much load on the machine! Run the machine in idling until the electronic signal indicator switches off.

PE 15-20 RT, PE 15-25:

The machine does not start. The electronic signal indicator (5) flashes. The restart protection is active. If the mains plug is inserted with the machine switched on or if the power supply is restored following an interruption, the machine does not start up. Switch the machine off and back on again.
