(21) and secure in place by fastening buckle and
tightening the straps (22). Repeat procedure for
second cylinder. Remove end of cylinder tags to
show cylinders are now in use.
Note:
Cylinders must be at room temperature for
maximum pressure and optimum performance.
Nitrous Oxide at room temperature is
approximately 740 psi.
2.
Place cylinder yoke nipples (20) into cylinder
valves. Hand tighten yoke nut.
DO NOT OPEN CYLINDER AT THIS TIME.
3.
Two reserve cylinders are recommended. They
can be purchased from your local gas supplier.
