Multicyl User Manual
**BE SURE TO READ THIS ENTIRE MANUAL PRIOR TO USING ANY MULTICYL PRODUCTS**
Section 13: Oil
Occasionally the Multicyl oil level may have to be topped up; but generally the sealed Multicyl oil system should only be replaced when doing a seal change, or after service of one year as part of a preventative maintenance initiative.
- Multicyl uses Shell Tellus 32 hydraulic oil, or an equivalent 150 SSU high grade hydraulic oil can be substituted.
Section 14: Safety
As the simplicity of Multicyl permits non-technical personnel to be involved in machine installations, accident prevention cannot be over-emphasized. Multicyl applications should be properly guarded to comply with all applicable standards for operator safety. Do not let the small size of a Multicyl mislead you - high forces are produced and severe injury may result if proper safety procedures are not adhered to.
- OSHA Regulations Section 1910.217 (c) states that: “It shall be the responsibility of the employer to provide and insure the usage of point of operation guards or properly applied and adjusted point of operation devices on every operation performed on mechanical power press; unless the point of operation opening is 3/16" or less.”
- In many applications the patented self adjusting stroke of Multicyl allows the pinch points to be eliminated by adjusting the position of the cylinder to eliminate openings greater than 3/16". In applications where this is not possible, such as tube piercing, common methods of compliance are to use guards at the point of operation or to use two hand anti-tie down operating controls.
- In addition to pinch points, compressed air poses another potential safety hazard. All fittings and air hoses must be properly connected. Due to the high forces produced by the compressed air, these pieces, when not properly installed, can become safety hazards to the operator.
The patented self adjusting stroke of Multicyl allows the point of operation opening to be adjusted to 1/4" on many applications. On applications where this is impossible or impractical, Multicyl can provide a two hand anti-tie down safety air control package.
Section 15: Warranty
Multicyl guarantees its products to be free from defect in workmanship for 1 year from date of purchase or 10,000,000 hits. Our warranty is limited to replacement or repair of defective parts at the discretion of Multicyl. This warranty is void if the cylinder is not used in conjunction with a properly maintained filter, regulator, lubricator mounted on the inlet port within 10' of the cylinder. Multicyl can not be held responsible for damage or injury caused by unsafe use or improper application of its products. All guidelines in this manual must be adhered to.
