Checking And Adjusting The Ground Pressure; Replacing The Break-Pin (Bioclip) - Husqvarna Rider ProFlex 18 Operator's Manual

Checking and adjustment of the cutting
unit's ground pressure
To achieve the best cutting results the cutting unit
should follow the underlying surface without pres-
sing too hard against it.
The pressure is adjusted with a screw on each side
of the machine.
Adjusting of the cutting unit's ground pressure is
conducted as follows:
1. Place a set of bathroom scales under the cutting
unit's frame (front edge) so that it rests on the
scales. If necessary a block can be placed
between the frame and scales so that the sup-
port wheels do not bear any weight.
2. Adjust the unit's ground pressure by screwing in
or out the adjusting screws located behind the
front wheels on both sides.
The ground pressure should be between 12 and
15 kg.
Replacing the break-pin (BioClip 103)
The blades are fitted with a break-pin to protect the
BioClip unit and its drive when colliding with
obstacles. A domed, spring friction washer is fitted
to each blade bolt. The washer must always be
replaced with a new washer if the blade bolt is
loosened. Otherwise the break-pin can break
causing the blades to collide.
Only use original spare parts. A set containing a
blade, break-pin and friction washer can be
purchased from your dealer.
1. Put the unit in the service position, see "Placing
in the service position".
2. Remove the blade (2A) by removing the blade
bolt with washer and friction washer (2B).
3. Remove the remains of the broken break-pin
(3).
4. Make sure the contact surfaces (4) on the blade
and the blade mounting are free from metal.
Clean if necessary.
5. Fit one new break-pin (5) in the blade
mounting.
6. Fit the blade (6), make sure it is fitted as
illustrated.
7. Fit a new friction washer (7) with the concave
face turned towards the blade.
8. Fit the blade bolt with washer (8). Tightening
torque 45-50 Nm (4,5-5 kpm)
