2. Installation
2.1. Installation of complete machine
2.1.1. Loading and unloading
Use a forklift (the arm length of the forklift shall not be less than 2.3m) to operate from the side of
the machine, and pay attention to the center of gravity of the machine. Since the center of gravity

of the equipment is biased towards the front end, the cross beam is usually moved to the rear end
for fixation.
Use lifting device: four lifting ring mounting holes are provided on both sides of the equipment table to
facilitate lifting with lifting rings.
Two sleepers are installed at the bottom of the factory equipment, which can be directly placed on the
flat ground。
2.1.2. Disassembly and assembly of the cover
Before installation, remove 4 middle side covers on both sides. The middle side cover is fixed on
the machine with two 3M Velcro stickers on the left and right. Pull up the left and right sides of the
upper part of the middle side cover to separate the bonding surface, and then remove the middle side
cover。
2.1.3. Remove the packing batten
Remove the fixing bolts of the packing wooden strip with an 8mm wrench, lift the equipment and take

out the packing wooden strip. (forklift or "lengthening" foot can be used to lift the machine)
2.1.4. Move the machine
The equipment is equipped with casters, which can be used to move the machine on a flat site.
Before pushing the equipment, be sure to "shorten" the anchor to make the casters fall to the
ground.
2.1.5. Initial leveling of the base frame
After the equipment is moved to the installation site, adjust the base frame height to make the
casters of the equipment completely suspended, and then start to adjust the table level. Note:
the weight of BK4 2516 equipment is 880Kg, and the ground flatness of the equipment
installation position shall not be greater than 2cm.
Leveling methods：
(1) Turn on the power and air supply, and open the air pump and air valve.
(2) Place the level on the felt at position 1 (Y direction) as shown in the figure, and adjust anchor a

and anchor B to center the bubble of the level. Note that the felt at the place where the level ruler
is placed shall be clean and avoid the felt joint.
(3) Place the level on the felt at position 2 (x direction) as shown in the figure, and adjust the anchor
C to center the bubble of the level. Note that the felt at the place where the level ruler is placed
shall be clean and avoid the felt joint.
(4) Tighten the lock nut on the base frame
2.2. Power supply
Users need to provide 3-phase 5-wire power supply (3 phase lines / 1 zero line / 1 ground wire),
and connect the power supply to the main input terminal of the power supply with 5-core cable.
The power access terminal of the equipment electrical box is shown in the figure.
The power output terminal of the equipment electrical box is shown in the figure. The electrical
box is provided with a 380V three-phase power socket and several 220V power sockets, which can

后前腰型槽 圆柱销
provide power for computer console, vacuum cleaner, milling cutter, feeding rack, etc.
2.3. Air supply
An air source interface is set at the back of the equipment electrical box, and a 12mm diameter air
pipe needs to be used to connect the "main air source inlet". Note: if the equipment is equipped with
additional functions such as milling cutter and pneumatic vibrating cutter, the corresponding air source
interface of the electrical box can be used; If there is no additional configuration, be sure to keep the
interface closed to avoid air leakage affecting the normal use of the equipment.
2.4. Cutting head installation
Tilt the machine head to the support plate on the beam, and the bottom of the machine head is close
to the mounting surface of the support plate. Make sure that the waist groove on the back of the head

slides into the cylindrical pin on the support plate. 
Rotate the nose forward with the bottom of the nose as the rotating shaft. Make sure that the stepped
cylindrical pin on the support plate slides into the hoist block on the back of the head.
Push the head down to the bottom (about 15mm), and insert the female flat plug on the head into the
male flat plug on the support plate.


Note: the limit slot on the back of the head must fit the clamping step on the support plate.
After installation in place, tighten two M5 fixing screws with 4mm Allen wrench.

2.5. Cutting tools installation
2.5.1. UCT installation
Put the sharp knife tool into the machine head, and the red dot in the UCT corresponds to the red dot
on the machine head.
After the UCT is completely put into the machine head, tighten it clockwise to complete the installation.

2.5.2. EOT installation
Put the EOT into the machine head, and the red dot in the EOT corresponds to the red dot on the
machine head
After the EOT is completely put into the machine head, tighten it clockwise, lock the fixing block, and
the installation is completed.
