Kickback and lock-in
- When working with the Power Cut there is a danger of kickback
and lock-in.
- Kickback occurs when the top of the cutting disc is used for
cutting (15).
- This causes the Power Cut to be thrown back toward the user
with great force and out of control. Risk of injury!
To prevent kickback, observe the following:
- Nevercutwiththesectionofthecuttingdiscshowningure15.
Be especially careful when reinserting the disc into cuts
that have already been started!
- Lock-in occurs when the cut narrows (crack, or workpiece under
stress).
- This causes the Power Cut to suddenly jump forward, out of
control and with great force. Risk of injury!
To prevent lock-in, observe the following:
- When reinserting the disc into previous cuts, have the Power
Cut running at top speed. Always cut at top speed.
- Always support the workpiece so that the cut is under tension
(16), so that the cut does not press together and jam the cutting
disc as it proceeds through the material.
- When starting a cut, apply the disc to the workpiece with care.
Do not just shove it into the material.
- Never cut more than one piece at a time! When cutting, make
sure that no other workpiece comes into contact.
Working behavior / Method of working
- Before starting work, check the work area for any hazards
(electrical wires, inammable substances). Clearly mark the
work area (for example with warning signs or by cordoning off
the area).
- WhenworkingwiththePowerCutholditrmlybythefrontand
rear handles. Never leave the Power Cut unattended!
- Use the Power Cut at high speed as far as possible (see “Tech-
nical Data”).
- Only use the Power Cut during good light and visibility periods.
Be aware of slippery or wet areas, and of ice and snow (risk of
slipping).
- Never work on unstable surfaces. Make sure that there are no
obstacles in the working area, risk of stumbling. Always ensure
that you have a safe footing.
- Never cut above your shoulder height (17).
- Never stand on a ladder to cut (17).
- Never use the Power Cut while standing on scaffolding.
- Do not lean over too far when working. When putting down and
picking up the Power Cut, do not bend over from the waist, but
instead bend in the knees. Save your back!
- Guide the Power Cut in such a way that no part of your body
is within the extended swing range of the disc (18).
- Use cutting discs only for the materials for which they are de-
signed!
- Use cutting discs only for the materials for which they are de-
signed. Do not use the Power Cut to lift up and shovel
away pieces of material and other objects.
Important! Before cutting, remove all foreign objects, such as
rocks, gravel, nails etc. from the cutting area. Otherwise, such
objectscanbeungawaybythediscwithgreatspeed.Injury

- Whencuttingworkpiecesdowntolengthusearmsupport.
If necessary, secure the workpiece from slipping, but do not
steady it with your foot or allow another person to hold it.
- When cutting round items, always secure them against rota-
tion.
- When guiding the Power Cut by hand, use the side mounting
position of the cutter attachment only when actually necessary.
Otherwise, always use the central position. This gives the unit
a better balance, for reduced operator fatigue.
