Working Behaviour And Working Technique; Cutting Metal - Solo 879-12 Manual De Instrucciones

7.3

Working behaviour and working technique

x For complex cutting processes, cutting direction and order of the cuts to be performed must be specified
in advance to prevent pinching of the cut-off wheel by the removed part and injury from dropping parts.
x Always hold the power tool with both hands. Have the right hand on the rear handle, the left hand on the
top handle. Firmly grasp the handles with your thumb.
x Operate the power tool at high speed when possible.
x Direction change (cutting radius below 5 m [approx. 15 ft]), side pressure, twisting or tilting of the power
tool during cutting is forbidden.
x When shortening work pieces use a secure support and secure the work piece against slipping and
twisting. The work piece must not be held with your foot or by another person.
x Always be ready for sudden kickback of the work piece and warrant the possibility of securely backing
away.
x Make sure that cut-off sections cannot fall resulting in injury or property damage.

Cutting metal

Always wear breathing protection equipment at dry cutting.
Metals are heated and melted at the point of contact by the fast rotation of the cut-off wheel.
x Rotate the wheel guard down as far as possible for sparks to fly forward where possible, i.e. away from
the user.
x Before cutting, specify and mark the cutting joint, and approach the material with the cut-off wheel at
medium speed. Only when the guide groove is cut, continue cutting at full throttle and increased
pressure.
x Only cut straight and vertically. Do not tilt or twist.
x For a secure and smooth cut, it is best to pull or to move the power tool in a controlled fashion. When
moving the power tool, do not push the cut-off wheel into the material in addition to the thrust caused by
the wheel's rotation.
x Large diameter round rods are best cut in steps.
x Thin tubes can be cut with a single sinking cut.
x Tubes with large diameters should be treated like large diameter rods. To avoid tilting and for better
control of the cutting process, do not let the cut-off wheel sink into the material too far. Do not allow the
mounting flanges of the cut-off wheel fastening to come into contact with the work piece. Always cut flat
around.
x Double-T carriers or angled steel should be cut in steps.
x Steel bands or steel plates are cut like tubes; pulling flat with long cutting area.
x Material under stress (supported or material in a wall) always has to be grooved slightly on the
compression side and then cut from the tension side so that the cut-off wheel is not pinched.
