3.1Shipping condition

(1)All SANDEX products are thoroughly inspected after the final assembly. Only those products that pass this inspection are shipped.

(2)Before shipped, each SANDEX unit is filled with lubrication oil in accordance to the customer’s operating speed and environment.

(3)A rust preventative solution is applied to the input /output shafts, key, and mounting surface. Vinyl tape is also used extensively to protect your SANDEX unit from scratches while transporting.

Remove the rust preventative solution with a light oil or thinner. Be careful not to let the light oil or thinner contact the oil seal. Never use thinner on or near the plastic sight gauge. This may cause severe clouding of the material.

3.2Temperatures

(1)For use between -20 to 0 degrees Celsius, (-4 to 32°F) use a lubricating oil with a lower viscosity than the recommended oil. This is because the dynamic viscosity of the lubricating oil rises in low temperatures and may not allow proper speed acceleration.

(2)For use between 40 to 70 degrees Celsius, (104 to 158°F) use lubricating oil with a higher viscosity than the recommended oil. This is because the dynamic viscosity of the lubricating oil lowers in higher temperatures and reduce the life of the equipment.

(3)For use between 70 to 100 degrees Celsius, (158 to 212°F) replace the oil seal and O-ring with a heat resistant synthetic rubber.

3.3Moisture

Rust may occur in storage or if the main machine is washed with water. Water does not have to come directly into contact with the unit to cause rust. Moisture, condensation, and other sources of humidity can also cause rust.

To use under these conditions, the mounting surfaces and shafts of the unit must be painted, or otherwise rust proofed. Applying mineral oil or grease to the mounting surfaces has a rust preventative effect and should always be practiced.

In addition, if the unit is directly subject to water, the sealing devices on the input and output must be changed to a waterproof construction.

3.4 Dust

SANDEX units are generally built resistant to dust. This is because the roller gear cam mechanism is enclosed within its own housing, and then sealed off at the input and output with an oil seal. However, depending on the amount of dust or other foreign particles, the
