Dismount completely the tensioning device (Fig. 9.5.1). Make 2
signs on the dismounted belt exactly 10 cm out of each other (belt
without tension) (Fig. 9.5.2). The purpose is to measure 10.2 cm on
the belt in tension what is a tension of 2%., a maximum of 2.5% is
allowed.
ATTENTION: NEVER “OVER” TENSION THE BELT, THE BELT
WILL BE DAMAGED AND IT WILL NEVER RECOVER ITS
ORIGINAL TENSION
Mount the belt back around the planetary pulley; see that the belt is
behind the driving pulley (Fig. 9.5.3). Put the belt around the left
roller of the tensioning device (Fig. 9.5.4). Put the tensioning device
back in place and pull the belt from the roller on the right side (Fig.
9.5.5). Put the belt around the driving pulley (Fig. 9.5.6). Begin to
tension until the measure of 10 cm between the marks becomes
10.2 cm (Fig. 9.5.7) (Fig. 9.5.8). Tighten the tensioning device while turning the bolt move the planetary head so
the belt can slide. (Fig. 9.5.8). Do not forget to lock the tensioning device (Fig.9.5.9).
9.6 REPLACING BELT AND PULLEY UNITS
In this section, we explain how to replace the belt and the pulley units. In some instances, the belt can be
replaced without replacing the pulley units, although it is always necessary to ensure that the pulley units are
working properly.

Pull out the socket from the motor cable to the carriage(Fig. 9.6.1).
Pull the water hose from the tank (Fig. 9.6.2)
Pull the handle out and put the head of the machine in an upright position. Take out the tools (Fig. 9.6.3).
Dismount the tool holders as described in the earlier paragraph “mounting and dismounting (Fig. 9.6.4).
Remove the two pins from the brackets (Fig.9.6.5)
Separate the carriage from the main head. Dismount the machine support Dismount the guard assembly. (Fig.
9.6.6)
Unscrew the top cover and remove the top cover by pulling it over the motor. (Fig. 9.6.7)
Mount back the machine support as this will make it easier to turn over the main head. (Fig. 9.6.8)
