4. Turn the indexable insert or, if all blades are
blunt, replace the indexable inserts.
5. Fix again the indexable inserts (22) with a
fastening screw (23). Torque: 5 Nm.
6. Turn the adjusting ring (15) in the opposite
direction, so that the holder for the indexable
inserts (24) is again in its normal work range. (So that the maximum permitted chamfer height is
not exceeded, see chapter Technical
Specifications).
9.2 Replace ball bearing stationary seal ring
(only if required):
Regularly check the ball bearing stationary seal ring
(21) for smooth running. Replace defective ball
bearing stationary seal ring. (order no.: 316093300)
1. Remove screw (20) and remove ball bearing
stationary seal ring.
2. Put new ball bearing stationary seal ring (21) in
place and add screw (20), tighten firmly.
9.3 Adjust scale (only if required):
The graduated ring (14) comes properly set from
the factory.
If indexable inserts are to be used for radii or if the
settings should have been misaligned, the scale
has to be adjusted as follows:
1. Lift the adjustment ring (15) and turn in such a
way that the indexable insert (22) does not
remove any material. (chamfer height = 0 mm)
2. Loosen the two clamping screws (14).
3. Turn the graduated ring (14) until the chamfer
height 0 mm is shown.
4. Tighten the two clamping screws (14).
5. Carry out trial cut.
10. Cleaning
Chips and particles can deposit at the cutter head.
This can lead to blockage of the cutter head.
Regularly clean the cutter head and its
surroundings and remove chips and particles.
It is possible that particles deposit inside the power
tool during operation. This impairs the cooling of the
power tool. Conductive build-up can impair the
protective insulation of the power tool and cause
electrical hazards.
The power tool should be cleaned regularly, often
and thoroughly through all front and rear air vents
using a vacuum cleaner or by blowing in dry air.
Prior to this operation, separate the power tool from
the power source and wear protective glasses and
dust mask.
11. Troubleshooting
11.1 Mains powered machines:
- Overload protection: There is a MAJOR
reduction in load speed. The motor temperature
is too high! Allow the machine to run at idle speed
until it has cooled down.
- Overload protection: There is a MINOR
reduction in load speed. The machine is
overloaded. Reduce the load before continuing to
work.
- Metabo S-automatic safety shut-down: The
machine has SHUT DOWN by itself. If the slew
rate of the current is too high (for example, if the
machine suddenly seizes or kickback occurs), the
machine switches off. Switch off the machine using the slide switch (5). Switch it on again and
continue to work as normal. Try to prevent the
machine from seizing. See chapter 4.1.
- Restart protection: The machine does not
start. The restart protection is active. If the mains
plug is inserted with the machine switched on, or if
the power supply is restored following an
interruption, the machine does not start up. Switch
the machine off and on again.
11.2 Cordless machines:
- The electronic signal display (9) lights up and
the load speed decreases. The temperature is
too high! Run the machine in idling until the
electronics signal indicator switches off.
- The electronic signal display (9) flashes and
the machine does not start. The restart
protection is active. The machine will not start if
the battery pack is inserted while the machine is
on. Switch the machine off and on again.
12. Accessories
Use only original Metabo or CAS (Cordless Alliance
System) battery packs and accessories.
Use only accessories which fulfil the requirements
and specifications listed in these operating
instructions.
Fit accessories securely. If the machine is operated
in a holder: Secure the machine well. Loss of control
can cause personal injury.
