NOTE! Loose tightening causes the outer frame deformed into an ellipsoidal shape under
the influence of the external pressure. All the Screws ○

NOTE! As loosening of the link between two bars during usage makes the parabola
unstable, tighten the extension firmly.
At this assembly stage, please choose one of the three
different positions depending on the solar altitude.
Position A Position B Position C
90 ° 82° 72°
45 ° 31° 24°
Fig. 13 Fig. 14 Fig.15
For high solar altitudes For medium solar altitudes For low solar altitudes
1. Check the latitude of the area where you plan to use the solar cooker.
2. Check the Diagrams for the Timing of the Solar Cooker Rearrangements at the end of the
- 7 -
User Manual. Select the set of circle charts applicable to the latitude of your area, and then
select “a.” or “b.” shown below.
a. I will rearrange the solar cooker to the appropriate position for each season, because I
want to be able to use the solar cooker all the time, all year round.
b. I will choose the position that enables me to use the solar cooker for the longest period of
time in the year without rearranging it because it’s a lot of work. (In this case, please note
that there will be some minutes of the day when you cannot align the solar cooker with the
sun at certain periods of the year.)
If you chose “a.” above, use the position applicable to each season
shown in the large circle chart.
Fig. 16 shows example of areas with latitudes between 25°and
27.5° N (in decimal degrees).
■The period of use: May 1 to Aug. 10 à Position A
■Aug. 11 to Sep. 10 and Apr. 1 to Apr. 30 à Position B
■Sep. 11 to Mar. 31 à Position C
Fig. 16 If you chose “b.” above, use the position shown in
the small circle chart at the top right of the large circle chart.
In this example, ■the suitable position is Position B.

4. Assembling the Mirror
1. Bent two ears on each of the KARU Mirrors ⑥,⑦and ⑧on the right lines
marked with notches at a 45-degree angle. See Fig. 27
It is highly recommended to bend them against a hard edge of a table or anything else to
achieve sharp lines. A round edge is NOT desired. Get straight sharp bent-lines.
NOTE! Incorrect bent-lines result in undesired finish.
NOTE! Be aware of a slight difference between locations of notches on both sides.

IMPORTANT NOTE! Please do not pull out black screws on four hookups of the
metal band as shown with ＊marks on Fig. 29, or the Center Mirror Assy. loses
its shape, and it is difficult to regain it.

3. Lay down the Center Mirror Assy. ○
3on soft cloth (the Parabola Cover may be used),
and loosen the screw as shown on Fig. 30.
If the Center Mirror Assy. is set on a cloth-covered bucket, rather than a cloth-covered
flat surface, you can make the assy. more stable during your works.
NOTE! Be careful not to spoil screw heads with the driver tip, or the scratches on the
heads cause poor results of mopping the mirror surface, with fine and nasty fibers
pulled out of a rag and left on screw heads.
NOTE! Excessive pressure on the nut on metal band makes it drop off to the under
side. Be careful not to press the screw head too strongly with the driver tip.
Loosen this screw at first.
