4. LIFTING THE MASTS

1): Loosen the top locking knob (G) of the top telescopic mast

(smallest).

2): Tighten the other locking knobs to ensure a proper lifting order.

The top-mast (smallest) has to raise first, followed by the

bigger mast below in sequence.

3): Pull the ABS (AUTOPIN BLOCKING SYSTEM (I))’s ring to

unlock the top telescopic mast (smallest).

4): Turn the winch crank (H) clockwise to raise the top-mast. When

the desired position is reaching, release the ABS’ ring; make

sure that the ABS’ auto pins have gone into its desired hole. If

you are in its maximum height, it will block itself.

5): Tighten the top locking knob (G) to secure the mast and to

avoid any lateral movement.

6): Repeat steps with the other masts.

7): Turn the winch crank (H) anti-clockwise a little to avoid the

cable to support any load.

8): You can add the load as long as all the ABS (AUTOPIN

BLOCKING SYSTEM (I)) are in place and the locking knobs

(G) are tightened against its masts and the cable is avoided to

support the load.
