3.2 FILLING THE WATER TRAY

The DAKAR PLUS models are designed to work with diamond disks cooled by water. Therefore, an important
part of the frame is a tray intended to serve as the cooling water deposit pumped in a closed circuit to disk.
ATENCION: Before plugging the machine to the electricity to effectuate any cutting operation, the water tray
should be filled until the pump has been completely covered.
During cutting operations, a large amount of dirt is accumulated in the tray. Thus, you have to change the
water as often as necessary to ensure the smooth functioning of the pump and the perfect cooling of the disk. The tray
has a stopper to remove once you want to change the water.

4. ELECTRICAL PLUGGING AND ADJUSTING THE DISK ROTATION SENSE

Upon receipt of the machine, make sure the network electrical tension is adequate before plugging the
machine. The electrical tension is to be found on the voltage indication next to the switch of the machine.
ATTENTION: Never plug the machine to electricity, in case the network power tension is not the adequate
as the engine would undergo irreparable damages
Once you have realised the previous steps and before placing the disk and manipulate the motor, it is
necessary to check and adjust the rotation of the motor axis correctly, you have to plug the machine to
the electricity and start it up, watching the rotation direction that must be clockwise. If necessary and
with three-phase motors, you can change the rotation direction swapping the two phase wires in the
aerial or in the peg of the feeding extension cord.
If necessary, you will have to swap the conducting cables to change the rotation sense of the disk. Do this
only with the machine unplugged from electricity.
ATTENTION: Never manipulate power supply cables or any other electrical equipment on the machine
before you unplug the machine from electricity.
Once the disk rotation sense has been adjusted, you can mount the cutting disk.

5. MOUNTING AND DISMOUNTING THE CUTTING DISK

The DAKAR PLUS models are designed to use segmented diamond disks and continuous rim disks either 300
or 350 mm of diameter
The cutting disks have different properties depending on the material to cut. Hence, an adequate selection of
the disk increases the performance and guarantees a better result.
Make sure the maximal supported revolutions by the disk are equal or superior to those of the machine's
engine.

5.1 MOUNTING/REPLACING THE CUTTING DISK

The disk can be mounted or replaced as follows:
• Make sure the power supply cable of the machine is disconnected.
• Remove the disk safeguard (P, Fig. 3) of the cutting bridge of the machine loosening the screws that fix it. (A, Fig. 3)
• Introduce the hexagonal key (E Fig. 3) in the nut (D Fig. 3) Block the rotation of the axis inserting the pricker
key in the bore placed outside (C, Fig.3), untighten the axis nut and remove the outer bridle (F, Fig.3).
ATTENTION: The nut is left-threaded
• Place the disk on its axis ensuring it is well centralised and perfectly located.
• Place the exterior bridle back and tighten the axis nut using the set of keys used before.
• Check the coupling between the disk and the bridles before tightening the nut.
• Place the safeguard back in its position and tighten well the screws fixing the cutting head.
• To dismount the disk, proceed in the inverse sense
ATTENTION: Remove all the used tools, making sure that all the elements of the machines have been mounted in the
correct position.
• You can plug the machine to the electricity.
