brakes separately with adjusting nuts (1) until the wheels
cannot be turned by hand any further.
Slacken the adjusting nuts two turns and check that the
wheels can rotate freely.

Maintenance
Note! Grease brake lever nipples (see arrows) weekly (or
every 50 running hours). It is recommended, that the brake
fluid is changed every other year.

2. Pump several times with the pedal in order to built up the
pressure in the system.
3. Depress one of the brake pedals and at the same time open
the bleed nipple on the br ake which is being actuated by the
pedal. Close the nipple and slo wly let the brake pedal up
again.
4. Repeat the pumping action with the brake pedal until the
brake fluid which runs out at the bleeding nipple is completely
free of air.
5. The procedure for bleeding the brakes is the same on both
sides.
