To check or replace the buffers, spiders or “O” rings the SAM tool holder has to be dismounted.Loose the security bolts
in the security disc (Fig.8.1.2) Remove the countersunk screws to take the disc off (Fig.8.2.2). Take out the security
bolts (Fig.8.3.2). The spider and buffers can be removed or replaced (Fig.8.4.2). Turn the buffers to take the security
disc off (Fig.8.5.2). By removing the flange by loosing four Hex cap bolts (Fig.8.6.2), the sealer cap comes loose
(Fig.8.7.2) and the “O” ring can be checked or replaced (Fig.8.8.2). Attention, for mounting use always the “blue” thread
locking adhesive except of the bolt to lock the buffers, depending on the number of buffers, the holder can be more
flexible or rigid (Fig.8.9.2).
REPLACING BELT AND PULLEY UNITS WITH PINS
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.
Disconnect the extension cord from
the power line and pull out the hoses
(Fig. 8.7)
Pull the handle out and put the head of the
machine in an upright position. Take out the
tools (Fig. 8.8).
