Cutting Discs - Makita DPC 6400 DPC 6401 Manuel D'instructions Et De Sécurité

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 disk! This will break the
disk! (10)!
Caution!
Never change direction (turning radius less than 5 meters /
16 feet), 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 arbour hole (bore) of the cutting disc must fit the shaft
exactly. If the arbour hole is larger than the shaft diameter, a
spacer ring must be used.
- Use only cutting wheels approved by the DSA (German Abra-
sive Disc Committee) or equivalent organisation for freehand
cutting at up to 4370 RPM (= 80 m/sec. at circumference) for
14"/350 mm discs, or up to 5100 RPM (= 80 m/sec. at circum-
ference) for 12"/300 mm discs.
- The disc must be free of defects (12). Do not use defective

cutting 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
instruction manual (13). Always place your left foot in the rear
handle and grasp the other handle firmly (with thumb and
fingers). 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 flies apart.
- When working with the Power Cut always hold it with both
hands. Take the back handle with the right hand and the tubular
handle with the left hand. Hold the handles tightly with your
thumbs facing your fingers.
- 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 the engine before inspecting the V-belt tension
or tightening it, replacing the cutting wheel, repositioning
the cutter attachment (side or middle position) or eliminating
faults (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
inflammable objects. The muffler is very hot (danger of fire).
- IMPORTANT: After wet cutting, first turn off the water feed and
then let the disc run at least 30 seconds, to fling off the remaining
water and prevent corrosion.
