3. Operation Instruction
3.1 Electric Voltage Detection
Danger
Check the Voltage whether the same with the nameplate!
3.2 Cutter Detection
Blunt cutter will damage and overload the machine!
Check the cutter regularly to avoid excessive wearing!
Make sure the cutter sharp!
Notice Change the direction of cutter or replace indexable tool before blunt!
3.3 Bevel Height Adjustment
1) Rotate the check ring (2) Until the slide caliper(4) And the main scale (3)To the bevel height
you wanted.
2) Use the check ring locking at the position.
3) Use the crescent wrench tightening the guide board device (1), not too tight.

2. Check Ring
3. Main Scale
4. Slide Caliper
Note: For not all milling cutter heads are the same length, so the data on the main scale not
exactly accurate, and usually adjust the bevel height accurate to the millimeter!!!
3.4 Instruction
Fix the machine and use it in a flat ground before using.
Do not touch the milling cutter head while it is working.
Keep a certain distance form the machine.
Not allowed to use the machine lifting over the head.

Can reuse the machine after the electromagnetic interference
disappeared.
The electric generator shut down automatically when the temperature is
too high.
When the above happens, let the machine cool down and use it.

Under the normal temperature, the machine will operate.
Notice: Advice bevel height better not beyond 2mm at the beginning, and operates the machine
slowly in order to know the performance clearly!

GMM-Series Milling Machine Welding & Cutting accessories
4.1 Conventional protective measures.
Make sure the power turn off.
Pull out the plugs form the socket.
Can not operate the machine in those cases: Turn on the machine accidentally and unknown
the machine’s performance.
4.2 Dismantle Milling Cutter Head
1) Keep a certain distance when rotates the
guide board components (guide board +
guide board rack)
2) Twist the drive shaft by the 44-52mm
wrench.
3) Then detach the guided shift head by the
hexagonal wrench.
4) Detach the milling cutter head from the
guided shift and the guided shift head by
the hook-type wrench (include the bolts,
directional bearing, guide bush, spacer
and spacer ring).
5) Put the cutting head and guided shift head
together.
Notice
Avoid damaging the screw hole, so just tight the screw by the
hand, not too tight!
4.3 Milling Cutter Head Replacement
Keep far away from the machine when rotates the guide board components (2) (guide board
+ guide board rack)
As picture shows, assembly including bolts, directional bearing, guide bush, spacer, spacer
ring and milling cutter head.
Put the lock shaft(3015R / 3018R) or the 44-52 mm wrench on the drive shaft, and then
tighten the cutting head on the drive shaft by the hook-type wrench.
As the picture shows, fix the guided shift head on the drive shaft by the hexagonal wrench.
If the guide shift head position is not yet fully aligned with the bevel cutter, adjust the spacer
numbers or the adjustment guide bush to keep them in the best position.

5.2 Steps:
Turn off the power supply;
Press the safe button;
Loosen the screw and detach the cutter;
Clean the cutter head (guide board rack and the back) and check whether exists damage;
Rotate all the cutter head and replace them at the same time;
Make sure all the replacement cutter heads are the same model;
Put the replacement cutter heads on the dent of the guide board rack surface(5);
Put the milling cutter heads on the homologous position and tight them by the hexagonal
wrench;
Check the cutter heads and make sure they are all tight.
Check the cutter heads are the same model and fix them on the surface of guide board rack,
and all the screws are very tight.
Operate the machine slowly at the beginning, once it backward suddenly, please turn off the
machine, check the model of the cutter heads and follows what we said above. If the
phenomenon still exists, please change all the cutter heads.
Note: 1) Please turn off the power supply when replace the cutter blades!
2) Replace the cutter heads not timely will damage the machine!
3) The installed blades should be close to the directional bearing tightly, that is, the cutter
head should be installed in the top slot of the directional bearing and the long blade should
be in the middle of the slot.

6. Speed Governing Instruction
6.1 Speed Setting Table
Processing object Speed setting Arcing time factor
Aluminum，Copper，
Plastics approximately 5500–7500 rpm 60 %
Material intensity≤400
N/mm² Speed 3–5 approximately 4500–6500 rpm 40 %
Material intensity > 400
N/mm² Speed 2–3 approximately 2500–4500 rpm 30 %
Chrome steel，Stainless
steel，Fine-grained steel Speed 2–3 approximately 2500–4500 rpm 20 %
Notice
Arcing time factor means the working time of the machine under
full load, this percentage was calculated on 100 minutes, such
as: 60% represents the machine can only work 60 minutes every
100 minutes.
Please pay attention to the arcing time factor!
6.2 Speed Adjustment Notes:
First adjust the speed to the mid-range(‘4’);
The bevel height should not too high at the beginning;
Reduce the rotation speed if much sparkle appears.
If there is no obvious sparkle appears, you can increase appropriate speed;
The faster the rotation, the faster processing;
More sparkle, the cutter damage more quickly;
Professional indexable cutter blade can take higher temperature and more sparkle, can adapt
to higher speeds as well;
For fixed operation object, the speed can be set in the “1”in order to avoid overload operating;
do not keep the machine at the same speed all the time.
7. Maintenance and Repair
