Multiplier gearbox
The multiplier gearbox is used for the transmission of torque from the pump to the fan via the
flange. It provides two-speed transmission which can be disengaged to stop the rotation (fan
switch-off). The multiplier gearbox and the pump are connected by means of a flange. The
multiplier gearbox is lubricated with the SAE 90 oil. It can be checked thought the window (6 −
Figure 7.7) and added through the filler plug (3 − Figure 7.7).

SWITCH-OFF AND GEAR
CHANGING
The multiplier gearbox with a shaft that
propels the fan has a switch-off lever
mounted at the side that switches off the
rotation or speed level of the fan. This way
the mist blower can be used for other
purposes (preparing the spraying mixture,
mixing, spraying with a manual spraying
lance etc.).
