<How To Assemble>
Required Tools
Open the Front Legs, install the Assist Legs to the Pillar with the supplied shorter
6mm bolts.
Firmly install the Rear Leg onto the Frame with the supplied longer 6mm bolt.
While you tilt up and hold the Arm, install the Gas Cylinder onto the bracket on the
Arm with supplied 6mm bolt and Nylon Nut.
Insert the Clamp Jaws from the front side of the Arm, then tighten it with the Flat
Washer, Lock Ring and Knob Nut (see Fig. A).
CAUTION
If you tighten the Clamp Jaws too firmly, it will be difficult
to rotate the jaws easily. Make sure you turn back the
Knob Nut 1/4 rotation after tightening.

<How To Use the Clamp>
You can both open/shut and adjust the clamp jaws with only one lever.
Pull down the lever, the jaws will open. Pull up the lever, the jaws will shut.
By tightening the small knob locating on the lever in the direction of clockwise,
you can slowly shut the jaws. Counter-clockwise will slowly open the jaws.
To clamp your bike, open the jaws fully and clamp the seatpost or the top tube,
then pull up the lever until it locks. Remember to adjust the width of the clamp
jaws before you clamp the bike.
When you pull up the lever, be sure you don’t pinch your finger in the jaws.
If you clamp a carbon or a light alloy thin tubing frame too hard, the frame may be damaged. Clamping
securely is important but you should not clamp so strongly on these kinds of frames.
When you clamp your bike, do NOT shut the jaws by rotating the knob bolt after pulling up the lever.
The bike may fall down from the jaws during the repair work due to insufficient clamp power.
W-400 can hold the bike at any angle you want.
While you push down the Clamp Lock Lever, rotate the bike then release the lever.
The inside gear will engage the lever and keep the desired angle.
When you clamp the seatpost with placing the bike on the floor, the gears may not be
able to engage the lever properly because of the defference of each position. At that
time you should free the clamp rotation by unhooking the Lock Ring (see Fig. B).
