Adjusting The Parallelism Of The Cutting Unit; Checking The Blades; Checking The Tyre Pressure - Jonsered FR13 Operator's Manual

Adjustment of the cutting unit's
parallelism
1. Dismantle the front hood and right-hand fender
as described on page 17.
2. Vertical adjustment of the cutting unit is made
with the adjusting nuts on the back edge of the
lift-strut.
3. Raise the cutting unit at the front edge by
shortening the lift-strut.
Lower the cutting unit at the front edge by
lengthening the lift-strut.
4. Tighten the nuts against each other after the
adjustment.
5. On completion of the adjustment the unit's
parallelism should be re-checked.
Fit the right-hand fender and the front hood.

Checking the blades

To achieve the best mowing results it is important
that the blades are undamaged and well-sharpened.
Check that the blades' attachment screws are tight.
IMPORTANT INFORMATION
Replacing or sharpening the blades
should be conducted by an authorised
service workshop.

Checking the tyre pressure

The tyre pressure should be 60 kPa (0.6 kp/cm
round.
To improve driving the pressure on the rear tyres
can be reduced to 40 kPa (0.4 kp/cm
The maximum tyre pressure is 100 kPa (1.0 kp/cm
IMPORTANT INFORMATION
Different tyre pressures on the front tyres
will result in the blades cutting the grass
at different heights.
