15. Adjusting the snow
plough
15.1 Adjusting the gauge wheels
Note
The two gauge wheels must always
be adjusted to be the same (discs
in same arrangement) to guarantee
safe and functional performance.
The higher the gauge wheels are
adjusted, the greater the wear on
the slide bar.
The slide bar must be checked and
reversed or replaced if necessary before
adjusting the gauge wheels. (
The height of the gauge wheels on delivery
(gap between slide bar and ground) is the
optimum setting to achieve the best
possible performance.
Adjustment procedure:
● Place the snow plough in the transport
position. ( 13.2)
● Insert a parallel support (1) (e.g.
wooden strip) along the entire width of
the snow plough.
Lower snow plough (2) and ensure that
the snow plough rests on the support
with the slide bar.
● Pull off lock washer (3) at gauge
wheel (4). Remove gauge wheel and
washers (5) downwards.
The gauge wheel height is determined
by the arrangement of the washers (5).
● Repeat this procedure on the second
gauge wheel.
● Place the snow plough in the transport
position. ( 13.2)

● Remove the support and lower the
snow plough into the working position.

15.2 Adjusting the coil springs
19
The coil springs act as a safety
device.
If you hit an obstacle (e.g. pavement), the
snow plough will swing forwards. This
dampens the impact.
Risk of injury!
If the coil spring setting
recommended by STIHL is
changed so that the tension is
increased, any impact will be
14.4)
harder.
Note
The setting must be the same for
both coil springs. Do not use
differing coil spring settings.
Recommended setting:
The optimum setting for both coil springs is
slightly preloaded.
Adjustment procedure:
● Place the snow plough in the transport
position. (
● Loosen lock nut (2) while holding
adjustment nut (1).
● Slightly preload the spring by turning
adjustment nut (1).
● Tighten lock nut (2).
● Repeat this procedure on the other
side.

15.3 Adjusting the lift rod
Danger of crushing!
Lower the snow plough into the
working position before performing
any adjustments. ( 13.3)
The lift rod can be used to adjust the effort
required to press the lift pedal.
Settings:
● Maximum lift position:
The lift rod (1) is attached to the top
bore in the lift arm.
● Middle lift position:
The lift rod (1) is attached to the centre
bore in the lift arm.
● Minimum lift position:
The lift rod (1) is attached to the bottom
bore in the lift arm.
Adjustment procedure:
● Detach cotter pin (2) from lift rod (1).
● Position lift rod (1) as required in one of
the three bores in lift arm (3) and fasten
using cotter pin (2).
Note
The higher the lift rod setting, the
more effort is required to press the
lift pedal.
A lower lift rod setting reduces the
lifting height of the snow plough.
