After removing the packing case, locate the RTP33 pellet press in a dry, well ventilated and well lit
location. Ensure that it is on a stable, level surface, then secure it with the foundation bolt.
To ensure safe operation, this machine must be earthed.
Unless you have requested a different voltage, your new machine will operate on a 380V supply.
When connecting the power, check that the direction the motor turns in is the same as the direc-
tion of the arrowhead. Be sure not to run it in reverse.
The electric current meter, button and indicative lamps are located on the front door of machine
base. A red lamp lights to confirm that the power is connected. When the motor is started the red
lamp is replaced by a green lamp.
When installing the powder hoppers, attention must be paid to the gap between the feeder
and the turret bench. This gap should be 0.05 – 0.1 mm – so that they are almost, but not quite
touching.
INSTALLATION THE PUNCH DIES
The turret contains 33 sets of punches arranged evenly around its edge. Each consists of an up-
per punch, a lower punch, and a die.
Before installing the dies, remove the dustproofing plate, hoppers, feeder and semicircular cover
at the front of the machine, and ensure all surfaces are clean.
i.
Loosen the dies’ locking screws on the turret, to avoid contact between the dies and heads
of the screws when installing.
ii.
There is a copper bar set through the upper punch hole; strike it lightly with a hammer to
loosen. Install the dies, ensuring that they are flat and tightly seated. The upper surface of each
die should be level with the upper working surface of the turret. Then tighten the screw.
iii.
To install the upper punches, loosen the cog of the upper orbit and oil the tails of the
punches. Then insert the punches into the turret holes. As you insert each one, turn it with your
thumb and forefinger to check that it can move up and down and rotate freely without friction. Af-
ter fitting, tighten the cog.
iv.
To install the lower punches, open the small access port on the main body of the machine.
The lower punches are installed following the same procedure as the upper punches.
v.
After the punches and dies have been installed, replace all the parts that you removed at
the outset. Rotate the turret by hand for a couple of revolutions using the hand wheel to ensure
everything is running smoothly. Check the upper and lower punches are moving cleanly, with-
out friction. Turn on the motor and let the machine idle for two or three minutes. If it is running
smoothly, begin production.
