OPERATING AND ASSEMBLY INSTRUCTIONS
Fig. 1:
To use the tfk trio, fold the pushbar(1) upwards. This will unfold the
trolley. Make sure that the pins (2) audibly engage in the lock. To fold
them together, pull the two locks (2) upwards, they will remain open
automatically. You can then fold the sliding rod (1) forwards. The
frame folds in automatically. To ensure that it remains folded during
transport, hook in the transport lock (3).
Fig. 2:
Push the front wheel into the opening provided (4) until it audibly
engages. By turning the adjustment knob (5) you can choose whether
the front wheel is locked in straight-ahead position or can turn freely.
If you press the grey button, you can remove the wheel downwards.
Fig. 3:
To mount the rear wheels, insert the axle into the frame so that the
brake is also in the holder (6). Attach the brake hook (7) in the M-
brake. If you wish to remove the wheels, release the brake hooks (7)
and press the kangaroo button (8) in the middle of the wheel. You can
now remove the wheels. You have the possibility to adjust the braking
force by turning the adjusting screw of the brake hooks (7) in or out
and secure them in the chosen position with the counter screw.
Fig. 4:
The hand brake (9) on the pushbar is both a running and parking
brake. To activate the parking brake, you must pull the brake lever
and turn the grey parking lever (10) so that the brake lever remains
fully applied and the brake is locked permanently. To release the
parking brake, pull the brake lever (9) and release the grey parking
lever (10). If the braking effect decreases, you can make a fine
adjustment. To do this, turn the adjusting screw on the brake lever
counterclockwise and check the braking effect again.
