2.1 Gearbox unit
The drive-shaft (A) from the electric motor drives the
two pinions B and C.
Pinion B runs on the inner shaft,
while pinion C runs on a hollow outer shaft that
encloses the inner shaft. The gearbox is greased for
life and requires no further lubrication.
Do not attempt to dismantle the gearbox and do not
expose the gear shafts to sudden shock loads, as
this can cause imbalance that will eventually destroy
the gearbox. If the inner shaft has to be struck for
any reason, ensure that a block of wood is placed
beneath it (refer to "Blade changing – 235 mm
blades",
Section
7.1).

2.2 Handle and electronic
The black control unit contains the electronics pack, the main switch and the mechanical lock-
switch. The latter must be depressed before the main switch can be operated. The
electronics pack is contained in the front section of the control unit.
The motor has an electronic control system. The electronics not only protect the motor from
overload but also provide smooth start-up and braking of the machine. When the main switch
is released the electronic system quickly brings the motor to a standstill. Abrupt braking is
technically impossible, as this causes sudden loading that would eventually result in damage
to the gearbox. The single-speed electronic control is set at 1900 min-1/ rpm for both saws.
The waveform run-up to full speed is quite normal. In this way the electronic system
eliminates the current peaks that usually occur when starting-up an electric motor. Electronic
control reduces the start-up current to about 12 A (without electronic control the start-up
current level would be around 18 A).
