Machine Assembly

Place the base flange of machine in such a way to fit table connection holes.
Make sure you tighten bolts after you place them with suitable Allen wrench.
WARNING! Make sure the connection surface of table is clean.
The smallest defect here (burr, small metal pieces) will prevent your machine to work vertically to ground.
After you place the bolts, remove package bands and uncover the machine.
To make machine adjustment for 90 degrees (See Picture-1) loosen bolts with number 1 and number 2 as in the picture (2 bolts facing each other). So that front head group will become free.
Press the mouth to which safe tap holder is connected,firmly on the surface you want to carry out tapping. (PICTURE 4/ 90 degrees of leaning mouth) Tighten bolts with number 1 and number 2 again after surface leans. Make sure surface leaning does not change during the process of tightening bolts. In that way 90 degrees adjustment of your machine will be done.
YOUR MACHINE IS SENT AFTER THE ADJUSTMENT IS MADE FOR 90 DEGREES.

Hardness adjustment mechanism which allows lifting its weight is available on the acrobatic arm. [See Picture 1) Front parallel arm group hardness adjustment can be done via handle with number 3 as seen on the picture, and handle with number 4 is used for rear parallel arm group’s hardness adjustment.

Operation of Machine

Machine includes a 3 kw electric motor. Firstly measure the currents coming to plug you will use before connecting your machine to plug and operating it. It must be 380 V between the phases and 220 V between phase-neutral. If alternating current is reaching to system, it will damage electrical system of your machine. In this situation, use a regulator to balance phases before operating the machine.
WARNING! Otherwise electric faults which may occur will not be in scope of guarantee.
Electric installation has phase protection relay. So that when phase with reverse order reaches to electric motor, phase protection relay activates and prevents the reverse operation of electric motor and hydraulic pump which is connected to motor from working in reverse direction, and protects the system. (See Picture 2) In such a situation if the machine is not working, remove machine’s three-phase electric cable and connect to another suitable three- phase socket. When the phase coming to motor is correct, system will activate.

To start the machine open pacco switch on unit and press on motor start button (green button) after waiting for 5 seconds. (See Picture 3) And hydraulic system will become activated

Operation of Machine

Button on handle at the end of acrobatic arm (See Picture 4) adjusts machine’s spindle rotation direction. Button stays at middle position automatically when machine is not used and spindle does not rotate.
To be able to turn spindle clockwise, press and hold the button to left. In that way spindle will rotate clockwise.
When you press and hold the button to right, spindle will rotate counter- clockwise.
Attach the tap you want for tapping to tap holder with suitable metric according to your tap. If the tap you will use is attached to a tap holder of different metric, your tap may break because of torque disagreement.
Place the teeth near tap holder in such a way to fit teeth sockets at the end of module, by pushing the ring on module at the end of spindle upwards, and release the ring; locking mechanism will work automatically and fix the tap holder. ( See Picture 4)
To remove tap holder from its place, it will be enough to lift ring on module upwards.Bring the tap (which is suitable for the hole you drilled beforehand, or which you will tap) on the hole and press slightly and provide mouthing (diameters of holes to be drilled according to taps for tapping can be found at the end of guide).
Then by pressing button to left side, make spindle turn clockwise. This way tapping tool will begin process of tapping for hole. When the process is done, by holding button pressed to the right, make the spindle turn counter- clockwise. In that way tap tool will come back from tapped hole. If you lubricate the tap with suitable grease before contacting with the material it will increase cutting speed and extend the life of the tap.
Machine’s transmission assembly has two stages and it works at 600 rpm speed at 1. stage for tapping processes between M5 and M12 (by making slower as tooth gets bigger via precision speed adjustment reducer) and it works at 2. stage 150 rpm speed for your tapping processes between M14 and M24 (by making slower as tooth gets bigger via precision speed adjustment reducer).
WARNING!
You need to work at 2. stage after M14. Otherwise hydraulic system and transmission system may get damaged. If you use it otherwise your machine will be out of guarantee’s scope. Stage transitions are adjusted via stage transition pin located at the left side of two-stage transmission assembly at the front head. [See Picture 5] Transmission assembly’s work spindle becomes free after pin is pressed.
When pin is in pressed state, transmission work spindle is pushed upwards, turned around its own axis and placed into its place and the pin is left. In case transmission work spindle is in the housing, the pin will be pushed back and lock the work spindle. Therefore transmission assembly will work at

1. Stage at 600 rpm speed.

IT WILL BE ENOUGH TO PRESS THE PIN AND PULL THE WORK SPINDLE DOWNWARDS TO GO TO 2.STAGE FROM

1. STAGE.

Pin is pressed again to go to 2. stage and transmission work spindle becomes free. Work spindle is pulled downwards for transition to 2. stage, pin will be pushed back again and will lock the transmission work spindle. Therefore transmissionassembly will be working at 2. stage at 150 rpm speed.
Acrobat M24 hydraulic tapping machine works at 600 rpm speed for tapping processes between M5 and M24. It is possible to adjust spindle cycle at speed adjustment dimmer, according to size of teeth you will tap.
You can use it at any speed by reducing cycle by using accurate speed adjustment dimmer for bigger teeth; and increase cycles with accurate speed adjustment for smaller teeth. Acrobat M24 hydraulic tapping machine can carry out tapping horizontally.
When you want to carry out tapping (See Picture 6) slightly loosen bolts with number 1 and number 2 as seen on the picture (two bolts looking at each other). This way the front head will turn to horizon and tapping head will be able to rotate 360 degrees.
Then only tighten bolts with number 2 and leave bolt with number 1 loose. Because head group needs to be free during horizontal tapping process. It is to ensure that head and related tap move easily at the axis of hole you drilled during horizontal tapping, and being able to adjust itself according to angle.
Your machine is ready for horizontal tapping process.

If you put tap holders whose job finished to the tap holder sockets at sides you can prevent possible accidents.
When your job ends with the machine, press the motor stop (red button) button at the unit and close pacco switch.
Keep acrobatic arm at closed condition when you are not working with the machine.

Maintenance of Machine

Fill oil tank in the table with minimum 901t, maximum 100 It with hydraulic oil (grade 46).
Periodically change hydraulic oil after 2500 hours of usage to use hydraulic motor and machine at desired performance with long life.
Track oil level with indicator at certain periods. Clean the inside of safe tap holders with pressured air at certain periods. Otherwise there may be breakage possibility for the taps.
Thin machine oil and grease shall be applied to suitable grease fittings at transmission unit at certain periods depending on machine’s operation frequency.

Filling Hydraulic Oil

When you want to fill machine with hydraulic oil, you can fill hydraulic oil (grade 46) at minimum 90 It, maximum 100 It with the help of funnel by opening storage cover as in the picture (See Picture-7).

To change hydraulic oil, open blind plug at the bottom of machine and evacuate hydraulic oil. After hydraulic oil is completely emptied, tighten blind plug again at its place.You can fill hydraulic oil (grade 46) with funnel (minimum 90 It, maximum 100 It) by opening storage cover.

Safe Tap Holder System

Safe type tap holders are produced separately for each metric tooth and they have a torque -adjusted system inside of them. This system is adjusted by producing company according to torque values which prevent breakage of tap you use, and prevents bei ng exposed to too much force. It reduces tap breakage risk to minimum. If the hole you use for tapping is a blind hole and if tap reached to bottom or if tap cannot move because of the jamming of burr created during tapping process or similar reasons, this torque-adjusted safe tap holder will become activated and even if you continue working for tapping, the mach  spindle will turn but will not rotate the tap and tap will not move. So that tap breakage risk will be reduced to minimum. Also decay of tapped part and tap tool costs will be minimum. According to variety of the tap you use and the hardness of part for which you are carrying out tapping, torque values of tap holders can be adjusted manually. Torque hardness of safe tap ho l der can be
increased or reduced. If your tap breaks before tap holder is activated remove wire segment at the front side of tap holder (See Picture 8) as seen in the picture, rotate interior hub of holder one grade in counter-clockwise direction in such a way to fit wire segment entrance holes on the hub, and place wire segment again to its place. In that way torque value of your tap holder will be reduced and your tap will not break with the activation of safe torque system before your tap breaks. To operate safe torque
system at later and higher torque values, apply the above mentioned process by rotating clockwise. In that way torque value of tap will be increased and torque system will be activated later.
WARNING! Attention must be paid at this process because the breakage risk of tap will increase as it will be exposed to bigger force.
