•
Lock the brake. It should not be possible to move the unit with average manual force.
A slight skip is acceptable when using greater force, i.e. more than 350 N.
•
Measure the power required for lifting the brake handle to locked position with a
dynamometer. If the power is not between 100 and 120 N, an adjustment must be done.
•
Tighten the adjusting screw with the brake released (pos. 2 / Fig. 23) until required brake
force is obtained.
•
After adjustments, make sure the brake wire link is oriented according to pos. 2 / Fig. 22.
Lock its position using the nuts (pos. 3 / Fig. 22).
Replacing the supporting wheels
Equipment required: 1 piece of wood (50 x 70 x 500 mm)
•
Jack up the unit with a wood block measuring 5 x 5 cm.
•
Block the rear wheels so that they cannot turn.
•
Remove the locking rings (pos. 1 / Fig. 24).
•
Remove the wheel shaft so that the supporting wheels can be removed.
•
Install the new supporting wheels and secure the shaft with the locking rings.
•
Check that the wheels move easily.
