Consider the following figures. The figure A shows a front view of a motorcycle parked on an inclined floor using its side stand while the figure B shows a side view of it but using its center stand.

I can make an instruction banner accompanied with those figures as follows.

When you park a motorcycle on an inclined floor as shown in figure A, please use the side stand. But if you park the motor cycle on an inclined as shown in the figure B, please use the center stand.

Question

If I don't want to attach the figures to the instruction banner, how do I have to rewrite the instruction in clear and understandable sentences? (As printing figures on the banner take more space and make the cost higher)
