Ether Starting Fluid
Ether is flammable and poisonous.
Use ether in well ventilated areas. Do not smoke while you
are replacing an ether cylinder or while you are using an
ether spray.
Do not store ether cylinders in living areas or in the operator
compartment of a machine. Do not store ether cylinders in
direct sunlight or in temperatures above 49 °C (120 °F). Keep
ether cylinders away from open flames or sparks.
Dispose of used ether cylinders properly. Do not puncture an
ether cylinder. Keep ether cylinders away from unauthorized
personnel.
Do not spray ether into an engine if the machine is equipped
with a thermal starting aid for cold weather starting
Lines, Tubes and Hoses
Do not bend high pressure lines. Do not strike high pressure
lines. Do not install any lines that are bent or damaged.
Repair any lines that are loose or damaged. Leaks can
cause fires. Consult your Rayco dealer for repair or for
replacement parts.
Check lines, tubes and hoses carefully. Do not use your bare
hand to check for leaks. Use a board or cardboard to check
for leaks. Tighten all connections to the recommended torque.
Replace the parts if any of the following conditions are present:
• End fittings are damaged or leaking
• Outer coverings are chafed or cut.
• Wires are exposed.
• Outer coverings are ballooning.
• Flexible part of the hoses are kinked.
• Outer covers have embedded armoring.
• End fittings are displaced. Make sure that all clamps,
guards, and heat shields are installed correctly. During
machine operation, this will help to prevent vibration,
rubbing against other parts, and excessive hear.
