Safety Instructions for power tools with a burnishing attachment
WARNING!
Read all safety warnings and all instruc- tions. 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.
Safety Warnings Common for Sanding,
Wire Brushing or Polishing
-
This power tool is intended to function as a sander, wire brush or polisher. Read all safety warnings, in-structions, 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.
-
Operations such as grinding or abrasive cutting-off operations 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. -
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.
-
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.
-
The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool.
Incorrectly sized accessories cannot be adequately guarded or controlled. -
Threaded mounting of accessories must match the grinder 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.
-
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 power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an 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.
-
Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As 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.
-
Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
-
Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting 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 could give the operator an electric shock.
-
Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
-
Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.
-
Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
-
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.
-
Do not operate the power tool near flammable materials. Sparks could ignite these materials.
-
Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating 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 wheel may either jump toward or away from the operator, depending on
direction of the wheel’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 by taking proper precautions as given below.
- Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.
- Never place your hand near the rotating accessory. Accessory may kickback over your hand.
- Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
- 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.
- Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.
Safety Warnings Specific for Sanding Operations
- 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.
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 trim any loose attachment strings. Loose and spinning attachment strings can entangle your fingers or snag on the workpiece.
Safety Warnings Specific for Wire Brushing Operations
- Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin.
- If the use of a guard is recommended for wire brushing, do not allow any interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces.
Safety Instructions for power tools with a pipe belt sander
attachment
WARNING!
Read all safety warnings and all instruc- tions. 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.
-
Hold the device by the insulated grip surfaces, as the sanding belt may come into contact with the power cord itself. A damaged live cable may cause metal parts of the device to become live and result in an electric shock.
-
Do not use the electric power tool if it has a damaged power cord. Do not touch the damaged power cord and pull out the mains plug if the power cord is damaged during work. Damaged power cords increase the risk of an electric shock.
-
Use the electric power tool for dry sanding only. If water penetrates the electric power tool, there is an increased risk of electric shock.
-
When working, guide the electric power tool with both hands. The handle must be attached! Do not switch on the machine until both hands are in the grip position.
-
Keep hands away from the running sanding belt. There is a risk of injury caused by crushing in the area of the guide rollers. On account of the operating mode and the guaranteed flexibility of the power tool these danger areas cannot be completely shielded.
-
Dust released from materials, such as lead paints, some types of wood, minerals and metal, may be hazardous to the operator or people in the vicinity. Inhaling or touching these dusts may result in respiratory diseases and/or allergic reactions.
– Ensure the work place is well ventilated!
– If possible, use external dust extraction.
– It is recommended to wear a respirator mask belonging to filter class P2. -
Do not work on materials which release hazardous substances (e.g. asbestos).
-
Never grind or cut light metals which have a magnesium content greater than 80%. Risk of fire!
-
If power tools are used outdoors or are exposed to excessive amounts of metal dust, connect them via a residual-currentoperated circuit-breaker (tripping current maximum 30 mA). Do not use any worn, torn or severely clogged sanding belts. Damaged sanding belts may rip, fly off and cause an injury.
-
Before using the machine, check that the grinding tools have been installed and secured correctly. Switch on the machine at no load for 30 seconds!
-
Interrupt the test run immediately if violent vibrations occur or other damage is established. Check the machine to determine the cause.

Work instructions for the pipe belt sander attachment
NOTE
When the appliance is switched off, the grinding tool continues running
briefly.
A belt sander has the following advantages over a grinding disc:
– cool sanding,
– clean finish without grooves,
– high stock removal rate,
– high productivity on account of large angle of contact (depending on
diameter).
Sanding:
NOTE
After placing the machine on the workpiece and before switching it on, check
that the belt is situated fully on the rollers.
– Pipes are machined between the rollers 11 and 12.
– The angle of contact and the stock removal rate can be varied by the contact
pressure.
– The smaller the pipe diameter, the larger the possible angle of contact. Up
to 270° are possible.
Sealing the surface:
Many manufacturers recommend sealing finished surfaces with a protective spray
(see Flex stainless steel accessories).
