Commissioning And Operation; Motor Electronics - Narex EFH 36-E9 Original Operating Manual

English
Attention!
Prior to the first use of the machine, correct collet chuck seating
in the cap nut (20) has to be checked. After full screwing the cap
nut (20) out, the collet chuck must remain in the nut and not in the
spindle. When removing the collet chuck out of the nut, the collet
chuck must apply moderate resistance, because it is seated in nut
recess guaranteeing that when loosening the nut, the collet chuck
will be taken out of the spindle.
Fixing the cutter into the incorrectly seated collet chuck and tight-
ening the cap nut can result in irreversible damage of the spindle!
This way damaged machine is not subject to the warranty repair!
Insert a not yet seated or a new collet chuck into the cap nut (20) and
depress it moderately by the fingers as far as the stop (collet chuck
"clicking" in the recess). Then you can screw the cap nut (20) onto the
spindle.
Depress the spindle lock (19). Turn the cap nut (20) and/or the spindle by
hand until the lock is arrested.
Put on the cutter. The cutter shank must be inserted by min. 20 mm.
Tighten the cap nut (20) firmly, using the chuck wrench (21) (SW 17).
Release spindle lock (19).
DO NOT tighten the cap nut (20) until the cutter us seated!
Cutter removal (a)
Depress the spindle lock (19). Turn the cap nut (20) and/or the spindle by
hand until the lock is arrested.
Loosen the cap nut (20), using the chuck wrench (21) (SW 17), release
spindle lock (19) and take the cutter out of the collet chuck.
Dust and splinter exhaust
The dust originated during the work can be deleterious, flammable and
explosive. Therefore adequate protective measures must be taken:
- The beech and oak wooden dust is cancerogenic, therefore use the
dust exhaust and wear a respirator.
- The metal dust that originates e.g. during light metals working can
be explosive or flammable; therefore work only in well ventilated
places.
Assembly of suction adaptor (b)
Turn the safety lever (16) to enable fitting the suction adaptor (22).
Turn the safety lever again to the right, thus fixing the suction adaptor.
For suction, a vacuum hose ø 30 mm can be directly connected to the
suction adaptor.
In order to ensure ideal exhaustion of chip material, the suction adaptor
must be cleaner regularly.
Use a special vacuum cleaner, suitable for the given worked material for
the exhaustion of an especially deleterious carcinogenic dry dust.

Commissioning and operation

Check whether the data on the name plate correspond with the actual
power supply voltage. Check whether the type of the plug corresponds
with the type of the socket. The tools designed for 230 V may be con-
nected also to 220 / 240 V.
Switching on
Press down the switch (1) on the holder surface, the switch will snap
in itself.
Switching off
Press the switch (1) in the upper part in the direction of the machine
body, the switch will jump back to the initial position.

Motor electronics

Starting current limitation
Electronic controlled smooth starting provides the start of the tool with-
out kickback. Due to limited starting current of the machine, 16 A lock-
out is sufficient.
Rpm selection
You can preset rpm using the controller (2) as follows:
Speed level 1: 8 000 min . ... Speed level 7: 25 000 min
-1
The required rpm depends on the router used and material worked.

The values mentioned in the above table serve for orientation only. The
required speed depends on the type of the material and working condi-
tions, and a practical test is recommended to verify it.
Constant electronics
Constant electronics keeps rpm at run and at load at an approximately
same value; this ensures equal picture of milled surface and increases
the service life of the router.
Overload protection depends on temperature
For overheating protection, safety electronics switches to cooling mode
when critical temperature is reached. The motor then keeps running at
about 5000 min
Once cooled down, the machine is again ready to run and fully load-
able.
The heat protection of machines heated by run reacts adequately ear-
lier.
Dislocation of holders
According to use, both holders (10) can be adapted individually to per-
sonal needs.
The holder can be rebuilt in 15° steps.
To do this, hold the machine firmly and pull the holder a bit. Place the
holder to the required position and let it snap back again.
Milling depth adjustment (c)
According to the finish, the milling depth can be adjusted in different
ways, even in more levels, if required. A total of three different milling
depths can be preset using the stepped backstop (14).
You can only adjust the milling depth when the machine is off.
Put the machine on the workpiece that is being machined.
1 Release the wing screw (18) for the depth backstop to make it move
freely.
2 Set the stepped bacsktop (14) to the lowest level; it will snap in no-
ticeably.
3 By turning the milling depth selector knob (7) (outer ring) move the
depth backstop (4) down, until it seats on the stepped backstop.
4 By turning to the left release the clamping lever and press the
machine slowly down until the router touches the surface of the
workpiece.
Turn the clamping lever to the right again to fix the machine in this
position.
Notice: By releasing the self-locking bolt (9) the clamping lever (8)
can be rearranged to suitable position.
5 Set the milling depth adjustment scale (inner ring (6)) to "0" (indi-
cator (5)). Make sure the depth backstop does not move up, other-
wise setoff to zero cannot be ensured any longer.
6 Set the required milling depth x by turning the selector knob (7).
The set milling depth will be deducted on the scale (6) and indica-
tors (5) (1 revolution = 25 mm / 1 segment = 0.5 mm).
Re-tighten the wing screw (18).
Notice: After each router replacement or after overturning the
inner ring stabilization to zero must be reset!

The preset rough adjustment of milling depth should be tested by prac-
tical tests and adjusted, if necessary.
