Thank you for purchasing an Outdoor Water Solutions Backyard Windmill. We designed this traditional style windmill with the same great engineering as our full size aeration windmills.
Please find the complete manual for the assembly of the OWS Backyard Windmill, company contact information and a copy of our 1 Year Workmanship and Parts Warranty.
1. DO NOT climb the tower. The head can turn without warning and is very dangerous. DO NOT use the tower cross members as steps as they cannot safely support your weight. The recommended method to service the windmill is to lay the tower on its side.
2. DO NOT attempt to repair or service the windmill on a very windy day. It is too unpredictable and dangerous, and you could be easily injured. Even in low winds, be very careful when servicing. Be certain that the blade is securely tied before beginning any work.
3. ALWAYS teach children about the dangers of the windmill and keep them away from it.
4. Keep your distance from the windmill in thunder, strong winds and lightning storms.

Ensure that all components are included prior to beginning assembly.

IMPORTANT NOTES: · Unless directed otherwise, do not completely tighten any bolts until your tower is fully assembled.

· When connecting leg sections always ensure that the lower leg section is behind the top leg section.

· There are two different styles of tower leg. The legs with the holes punched in one side are for the top sec-

tion; these holes are used to install the decorative maintenance platform.

1. Assemble each of the cross brace support "X" sections for the middle and bottom sections for all four sides as shown in Figure 1. This includes the cross brace tensioning systems. The cross brace tensioning system consists of two (2) 1/4" nuts, one (1) 5/16" x 1/2" bolt, one (1) eye bolt, one (1) 5/16" Flange nut and one (1) L-bracket. The cross brace tensioning systems are to be installed on the 24" and 25" cross braces only. When installing the cross brace tensioning "L" bracket, try to position all of them at the same height on each of the eye bolts; this will simplify the squaring process later. Refer to figure 3 for further detail on installing the cross brace tensioning systems on the 24" and 25" cross braces.

2. Begin the tower at the very top. Take the four tower top legs and fasten them to the tower cone with the eight 1/4" x 1/2" bolts, 1/4" washers & 1/4" nuts, ensuring that the holes in the tower top legs are toward the top of the tower and are across from each other (see figure 2). If this is not done, the entire top section will need to be taken apart and reassembled in order to install the decorative maintenance platform. Completely tighten all of these bolts.


TIP: From this point on, it will be simplest to assemble the tower while it is laying on its side. Assemble on a soft surface (e.g. lawn, cardboard, drop cloth, etc.) to prevent scratching.

3. Install the middle section of each side using two 1/4" x 3/4" bolts, two legs, one middle section cross brace "X" (assembled in step 1 above) and one 12" Cross Member. These parts should be attached to the top legs in the order just described from outside to inside. One nut can be then be placed onto each of the two bolts ­ do not completely tighten yet. Repeat this process for all four sides. Refer to figure 1 and figure 3 for assembly illustrations.


TIP: Start with the side that is on the ground then complete the vertical sides then the top side. When working on the sides that are not on the ground the 21 1/2" cross members can be installed temporarily using eight 1/4" x 3/4"

bolts and nuts to provide support and stability (see figure 1).

4. Repeat the process used in step 3 above to attach the bottom section. Make sure that the 27 1/4" cross braces and cross brace tensioner L-brackets are included when connecting the bottom section parts to the middle section. They should be installed between the 19 1/2" cross braces and the 21 1/2" cross member (see figure 1 and figure 3). Install the anchor brackets and 31" cross member as part of this step. The anchor brackets should be installed first (see figure 4), then the leg, then the 28 1/4" cross braces or L-bracket, then the 31" Cross Member. Insert the 1/4" x 1" bolt through the anchor bracket (see figure 4) but do not tighten until the tower is erected in its final position and the stakes are driven through the clamps.


TIP: You will need to remove any 21 1/2" cross members temporarily installed in step 3 above in order to install the bottom section.

TIP: You may need to loosen or tighten the L-brackets on the eye bolt in order to complete this step ­ try to loosen

or tighten all four L-brackets on each section equally.

5. Square up the middle section by adjusting the cross brace tensioners in the middle section. When all cross braces are tightened, turn the nut above the L-bracket so that it is tight to the L-bracket. Repeat this process for the bottom section.

6. Install the Decorative Maintenance platform using four 1/4" x 1/2" bolts and nuts.

You have now completed assembling the tower of your Backyard Ornamental Windmill.

IMPORTANT NOTES: · When installing the tail arm it is very important to ensure that one end butts up against the fan support

shaft welded inside the head connection bracket and the other end is flush with the back of the tail fin

bracket. If this is not done the windmill may not track the wind properly.

· Ensure that all bolts are completely tightened throughout the head assembly.

1. Install the tail fin onto the tail arm with the tail fin bracket and four 1/4" x 1/2" bolts and nuts and eight washers as shown in Figure 6.


IMPORTANT: Make sure that the end of the tail arm is flush with back of the bracket

2. Insert the other end of the tail arm into the head connection bracket until it butts up against the welded fan support shaft. Once the tail arm is inserted completely use one of the 1/4" x 1 1/2" bolts and nut to clamp the tail arm into place as shown in figure 1. Tighten the bolt fully to ensure that the tail arm cannot come out.


IMPORTANT: Make sure that the end of the tail arm Butts up against the fan support shaft.

3. Insert the pivot tube into the head connection bracket so that the pivot tube is between the three remaining holes in the head connection bracket as shown in figure 5. Insert three remaining 1/4" x 1 1/2" bolts through the holes and completely tighten the bolts.

4. Install the fan onto the Fan Support Shaft and tighten all of the set screws completely.

5. Insert the pivot tube through the pivot tube washer then into the plastic tower top as shown in Figure 7.

IMPORTANT NOTE: · Outdoor Water Solutions Windmills will not determine soil and wind condi-

tions for any windmill installation. Therefore, these conditions must be deter-

mined by the customer. Anchoring of the windmill tower is very important. It

is the customer's responsibility to adequately anchor the tower. Outdoor

Water Solutions, Inc. supplies a basic anchoring kit with each unit. However,

in certain circumstances, such as light soil conditions and high to extreme wind

areas, it may be necessary to utilize other anchoring techniques. Concrete pil-

ing, concrete pads, or screw in anchors are some examples. The customer is

responsible to anchor the windmill adequately or consult the appropriate peo-

ple to do so.

· Read through this entire procedure prior to beginning.

1. Choose an area in your yard (app. 3' x 3') that is level, or close to level. 2. Stand the assembled windmill up on the location you have selected for installation.

Figure 9

3. Drive the stakes into the ground through the anchor brackets. Make sure to leave the stake clamps at approximately the same height to simplify the levelling process.

4. Level the windmill as follows: a. Starting with the highest leg drive the stake until it is 1/4" above the stake clamp as shown in Figure 8. Tighten the 1/4" x 1" bolt in the stake clamp to secure the leg to the stake. b. Moving in a clockwise direction, move the stake clamp on the next leg to the top of the stake leaving 1/4" above the clamp. Tighten the 1/4" x 1" bolt in the stake clamp to secure the leg to the stake. Drive the stake into the ground until the leg is level with the last secured leg. c. Repeat "b." above until the tower base is level. d. In order to eliminate any sharp points, Move the Stake clamps up the stakes until they are even with the tops of the stakes as shown in Figure 9.
