Cat Hawk Assembly Instructions

Ensure you have all the correct pieces:

1 x Vane Arm
1 x Fixed Reference Arm
2 x Adjustable Reference Arms
1 x Aluminium Support Rod
1 x Locking Block
1 x Bridle Clip 1
1 x Bridle Clip 2
1 x Large Self Tapping Screw

The Vane Arm should be perfectly balanced when it leaves the factory.

Test this by putting the Support Rod into the vane arm and just slowly lift it off the table. The Vane Arm should remain parallel to the table

 

If either end of the Vane arm drops quickly you will need to reposition the Counter Weight.

Gently bend the front of the Vane Arm until the counter weight lifts up. Slide it in the necessary direction and retest.

When the position of the Counter Weight is correct ensure it is securely pushed into the Vane Arm

Slot the Fixed Reference Arms over the Vane Arm spindle with the reference points facing down.

Push it up hard until it clicks into position.

The angled arms can face the front of the Vane Arm or the back of the Vane Arm depending on whether you prefer to use them up or down wind.

Fit the 2 adjustable Reference Arms into the top of the Locking Block. Place the lip of the Vane Arm shaft into the locking block recess.

Push the Support Rod up through the Locking Block and into the Vane Arm. Push the Support Rod in far enough to ensure the vane arm is lifted clear of the Locking Block Surface as in the photo.

The Vane arm should now turn perfectly with no friction. Tighten the bottom of the 2 screws to lock the Locking Block onto the Support Rod and the top screw to tighten the Reference Arms.
