Since hexagon screw h (Fig.
118)
is
loose, the motor shaft can
be
tilted
toward the
bedplate

the
lower end

the
cord
belt
can
be
slipped
onto
sprocket g.

Tilt
the sprocket-end
of
the motor
shaft
away
from the
bedplate
until
the
cord
belt
is
tensioned slightly.
Hold
the motor
shaft
in
this position
and
tighten hexagon screw
h.

sure the cord
belt
is
not tensioned

Turn the
balance
wheel
to
see
if all
parts work properly.
If
the machine
is
equipped with a
balance
wheel
with free-wheeling device, which
can
be
used
for
both foot
and
power drive, set the
balance
wheel
for foot drive,
and
check whether
the driving belt sprocket remains
stationary when you turn the
balance
wheel.
If
the free-wheeling device
should not hove
disengaged
the mo-
tor
belt sprocket, hold the cord belt
briefly when you start treadling.
