How many cubic feet is 312 sq. ft.


There is no relation between square anything to cubic anything.
If you want to calculate how many cubic feet 312 sq tiles are, you need to tell how this the tiles are.
Cubic is length x width x hight.
square is length x width.
All in the same dimension so even 1/4 of an inch, should be added in feet. with 0,00xx I don't want to calculate in these old measures anymore.

What is the slope buttons used for


If you have the standard RL-H3C then there are 3 buttons. Starting from the left there is the "height alert" then "manual" then "Power".

Height alert is a function that after the laser levels and spins monitors the position of the laser. If the laser moves more then a tiny amount then the height alert function is tripped, and the laser flashes it's lights and stops spinning (or spins slowly) to let you know the base line position of the laser has changed. Pressing the height alert button twice shuts this mode off.
Manual mode means after the laser is leveled, it completely ignores the level vials. You can turn the laser any way you want to and it will always spin and not cause any errors.
Power is self explanatory.
If it's a RL-H3CS then it has two arrow buttons, that when in manual mode, allot one axis of the laser to be manually adjusted up and down to do a manual slope.

What is tourine


Taurine, or 2-aminoethanesulfonic acid, is an organic acid widely distributed in animal tissues. It is a major constituent of bile and can be found in the large intestine and accounts for up to 0.1% of total human body weight.[1] Taurine has many fundamental biological roles such as conjugation of bile acids, antioxidation, osmoregulation, membrane stabilization and modulation of calcium signaling. It is essential for cardiovascular function, and development and function of skeletal muscle, the retina and the central nervous system. Taurine is unusual among biological molecules in being a sulfonic acid, while the vast majority of biologically occurring acids contain the more weakly acidic carboxyl group. While taurine is sometimes called an amino acid, and indeed is an acid containing an amino group, it is not an amino acid in the usual biochemical meaning of the term, which refers to compounds containing both an amino and a carboxyl group.

Everything works fine with the cover off, but the flame is snuffed out when you put the cover back on.


Straigt up this is not getting the right air to fuel ratio. Check for a filter that is plugged/dirty. Also check where the air intake is in relation to everthing and make sure that none of the parts are bent or distorted in a way that would prevent the air flow from flowing properly.

Craftsman 19.5 briggs & stratton mower new battery, new solenoid new brushes on starter. fuse & wiring good shape. when i attemp to start ignition all it does is click.


Check the voltage on the battery to see if it is 12 volts or higher. If not, charge battery.

Then check all starting-related electrical connections-- sounds like there is a dirty connection somewhere if the battery is charged.
