  1.  Installation and Connection
    1. Tablet Press Machine should be installed on the wood workable (as well on
the cement table). Use three units of M12 bolts for fixing it. The height between the workable surface and ground is around 600mm (consider easily to the operation). To be convenient to disassembled and repair, there should be a hole on the wood workable that its diameter around 35mm counter to the position of lower punch.
3.2. To insure the safety connecting ground wire before connecting the power, and then remove the triangle belt, connect the power of the machine and switch it on to observe the roiling direction of the operation. (The rotary direction of motor shaft should be on the same direction of the arrow of large pulley wheel). If the rotary direction is incorrect, you should connect another line, and then install the triangle belt.
 
  1. Uses of Dies
    1. Assemble the Die
4.1.1. Assemble the lower punch
Unscrew the fixed screw of lower punch, rotate the hand wheel to make the lower punch raise to the top location and insert the lower punch to the hole (Attention the gap aim at the lower punch tighten bolt). At last screw the fixed bolt of lower punch.
4.1.2.Assemble upper punch
Unscrew the upper punch tighten nut, insert the upper punch to the hole, and then screw the tighten nut.
4.1.3. Assemble the middle mould
Unscrew the fixed screw of middle mould, and put the mould into the hole of mould plate, in the meantime insert the lower punch into the hole. Push it to the bottom of the hole and then tighten the fixed screw of middle mould.
 
4.1.4.Turn the hand wheel by hand, let upper punch slowly drop to the hole of middle mould, and observe whether there is collision or friction, if it happens, you can unscrew the fixed nuts (two pieces) of mould plate, adjust the fixed location of the middle mould plate, make the upper punch put into the hole of middle mould, and then screw the fixer nuts, adjust it till no collision or no collision or no friction it can be called qualified installment.
4.2. Adjustment of the Tablet Out
Turn the hand wheel to raise the lower punch to the top location, observe whether the surface of lower punch and middle mould are on the same level, if not, it will influence the tablet out. When this situation happens, unscrew the butterfly screw and loose gear plate, rotate the upper adjusting gear, make the surface of lower punch and middle mould on the same level, then press the plate, tighten the butterfly screw.
Next step, turn hand wheel and make the empty machine run for ten circle. If it goes well, and then you can put some material into the machine, and try to press the material into tablet, then do next adjustment.
4.3. Adjustment the filing depth (the adjustment for the weight of tablet)
Loose the butterfly screw and loose the gear press plate, turn left the down adjustable gear to raise the lower punch, and the filling depth will be reduce (the weight of tablet also will be reduce). On the contrary, increase the filling depth, the weight of tablet will also be increased. After adjustment, you should to install the gear plate and tight the butterfly screw.
4.4. Pressure Adjustment (adjustment of the hardness of tablet)
Loosen the knurled screw, downward adjusting the eccentric cooper sleeve, and the pressure increased; hardness of the tablet would be increased. On the contrary, turning it to move up would decrease the pressure and lower the hardness of the tablet. After adjustment, tighten the knurled screw and lock the eccentric copper sleeves.
Till now, the adjustment of the die is basically completed; restart the machine for
trial press several times to check the weight of the tablet, hardness and surface etc. If it’s qualified, you can put into production. During the operation, you can check the quality of the tablet anytime and adjust it immediately.
4.5. Disassembly of the Die
4.5.1. Disassembly of the upper punch
Loose the fixed nut of upper punch and pull out the upper punch. If it’s combined very tight, you can use clamp to pull the upper punch out, but attention to protect the shuttle edge punch.
4.5.2.Disassembly of the middle mould
Loose the fixed screw of the middle mould and Loose the fixed nut of lower punch. Loose the butterfly screw and loosen the gear press plate. Turning and adjusting the gear to raise the lower punch around 10mm. Turning the pulley, make the mould expose some parts by the lower punch; carry out the middle mould by hand. If the mold is close with the hole, you can not force to rotate the hand wheel, in order to avoid damage the parts. At this time, you should disassemble the mould plate, and then carry out the middle mould.
4.5.3. Disassembly of lower punch
Loose the fixed screw of the lower punch and the turning hand wheel to raise the lower punch to the top point, then you can pull the lower punch out. If it’s combined very tight, you can use clamp to pull it out.
(Attention to protect the shuttle edge punch).
4.5.4.After disassembly of the die, it’s still necessary to adjust the gears. Lower the lower punch around 10mm, turn the hand wheel to raise the lower punch to the highest location, no higher than the bottom of the middle mould (This step cannot be ignored, avoiding collision between lower punch and middle mould next time). At last tight the fixed screw of lower punch.

Assembly: Refer to above instruction in counter sequence.
5.5. Main shaft
Disassembly: Disassembly the main shaft should be done by two persons. Disassembly the protection casing first, then disassembly the big gear, unscrew the fixed nuts of the lift cam and eccentric. Disassembly the feeder cam, then tap the shaft end with wooden hammer  and copper rod (Attention not to damage the screw hole of shaft end). At the same time, hold other end of shaft and nip the eccentric boss and lift cam, slowly disassembly the main shaft. (Do not lost the lift roller and feeder roller.)
Assembly: Refer to above instruction in counter sequence.
  1. The Lubrication and Maintenance of the Machine
6.1. The lubrication on the friction of each movement part is key point of maintaining the normal operation and prolongs the lifetime, especially when the main movement parts are running under the situation of lacking oil, it will quickly damage the main movement parts, even the movement parts can not be used again. So, before you use the machine, please add lubrication on the oil cup, oil hole and friction surface. And running the empty machine to make the friction surface full of oil film. At this time, you can use this machine now. And you should add oil each shift, but do not need add too much oil, or the oil will overflow, which will pollute tablets. The injection place and times refer to following chart.
