250 Hours Service - Inspect Parking Brake (optional)
Inspect the following:
Parking brake lever
If it can be pulled further backwards than 90° (midway), using a traction
of approximately 25 kg, the cable needs to be adjusted.
Parking brake cable
Inspect the parking brake cables for possible wear or damages. Replace
worn or damaged parts.
When the parking brake is relieved, the cable must be limp; otherwise it
needs to be adjusted.
Correct length:
•
When the brake is relieved, the cable must be tight and yet not
stretched.
•
Lengthening/shortening of the parking brake cable is carried out
by adjusting the turnbuckle located inside the frame.

ATTENTION! There are two versions of the hand brake system
available. One version is connected to the centre of the wheel
axle (see picture to the right), the other version is connected near
the wheel.

Once the brake lever (A) is adjusted, tighten the cable by moving the hand brake lever (B) back.
