Cutoff discs
- The protection hood must always be on! Change discs only
with the engine off!
- There are two basic types of cutoff discs:
- For metal (hot cutting)
- For masonry (cold cutting)
NOTE:
When using diamond cutoff discs, always make sure to observe
the "direction of rotation" markings. Diamond discs should only be
used for cutting masonry/brick/ concrete etc.
- Cutoff discs are intended only for radial loading, i.e. for cutting.
Do not grind with the sides of the cutting disc! This will break
the disc (10)!
Caution!
Never change direction (turning radius less than 5 meters /
5 1/2 yards), exert lateral (sideways) pressure, or tip the Power
Cut during cutting (11)!
- Use a cutting disc only for cutting the materials it is intended
for. The proper type of disc must be used, for either metals or
masonry.
- The arbor hole of the cutting disc must be an exact Þ t with the
arbor or shaft. If the arbor hole is larger, it must be Þ tted with an
adapter ring (available as an accessory).
- The cutting disc must be rated for freehand cutting at up to 4370
rpm or 80 m/sec for 350 mm discs, or up to 5100 rpm or 80 m/s
for 300 mm discs. Use only cutting discs that comply with EN
12413, EN 13236.
- The disc must be free of defects (12). Do not use defective cut-
ting discs.
Always tighten the cutting disc mounting bolt to a torque of 30
Nm. Otherwise, the cutting disc can twist.
- Before starting the cutting disc, make sure you have a steady
footing.
- Put the Power Cut into operation only as described in this instruc-
tion manual (13). Always place your left foot in the rear handle
and grasp the other handle Þ rmly (with thumb and Þ ngers). Other
starting methods are not allowed.
- When starting the Power Cut it must be well supported and
securely held. The cutting disc must not be touching anything.
- If the cutting disc is new, test it by running it at least 60 seconds
at top speed. When doing this, make sure that no persons or
body parts are in the extended swing range of the disc, in case
it is defective and ß ies apart.
- When working with the Power Cut always hold it with both
hands. Take the back handle with the right hand and the tubu-
lar handle with the left hand. Hold the handles tightly with your
thumbs facing your Þ ngers.
- CAUTION: When you release the throttle lever the disc will
keep spinning for a short period of time (free-wheeling effect).
- Continuously ensure that you have a safe footing.
- Hold the Power Cut such that you will not breathe in the exhaust
gas. Do not work in closed rooms or in deep holes or ditches
(danger of poisoning by fumes).
- Switch off the Power Cut immediately if you observe any
changes in its operating behavior.
- Switch off engine before refuelling, changing the cutoff disc, work
breaks, transporting or moving the Power Cut, taking it out of
operation, or dealing with malfunctions. Before any maintenance
work, move the combination switch to the lock symbol (14).
- Turn off the engine immediately and check the disc if you hear
or feel any change in cutting behaviour.
- Turn off the Power Cut when taking a break or stopping work
(14). Place the unit in such a way that the disc is not touching
anything and cannot endanger anyone.
- Do not put the overheated Power Cut in dry grass or on any
inß ammable objects. The mufß er is very hot (danger of Þ re).
- IMPORTANT: After wet cutting, Þ rst turn off the water feed and
then let the disc run at least 30 seconds, to ß ing off the remaining
water and prevent corrosion.
