It is important that you read the entire manual to become familiar with this product before you begin using it.This telescopic cylinder is designed for certain applications only. Northern Tool and Equipment is not responsible for issues arising from modification or improper use of this product such as an application for which it was not designed. We strongly recommend that this product not be modified and/or used for any application other than that for which it was designed.For technical questions, please call 1-800-222-5381.Intended Use (4)Packaging Contents (4)Technical Specifications (4)Important Safety Information (4)Specific Operation Warnings (6)Main Parts of Telescopic Cylinder (6)Assembly Instructions (6)Operating Instructions (14)After Each Use (17)Maintenance (17)Troubleshooting (18)Parts Diagram (18)Parts List (19)Replacement Parts (19)Limited Warranty (20)The NorTrac series telescopic cylinders are ideal for construction, mining, forestry, marine, demolition, military, material handling, agriculture, truck and trailer, loader, utility, and waste management.•Telescopic Cylinder •Owner’s ManualCylinder DisassemblyBefore Disassembling the Cylinder•Dismantle the cylinder in a clean location.•Each part should be thoroughly cleaned. If the cylinder is to be dismantled for any length of time, coat the metal parts, which are to be reused with a good rust inhibitor and store them in aprotected area.Disassembling the Cylinder1. Un-thread the top screw on the rear cap (#23).2. Remove the rear cap.3. Drain the oil inside.4. Knock the trunnion (#31) to force the inner piston rod (#32) out.5. Take out the piston rod (includes a larger and smaller one).6. Knock the inside edge of the piston rod to find the correct position of the inner support ring.7. Remove the support ring.8. Punch holes into the back of the inner groove.9. You may also drill holes with a power drill.10. Rotate the inner back-up ring hole at an angle (using the process above) to remove the innerback-up ring (#9).11. Take out the two piston rods inside.12. Repeat steps 8, 9, and 10. Remove the back-up ring (#9) from the larger piston rod.13. Take out the smaller piston rod.14. Remove the #8, the #16, and the #19 BS seals from the larger and smaller piston rod.15. The #18 back-up ring is at the other end of the piston rod. See the image below.Reassembly Procedures1. Place the 3rd stage tube (#2) back inside the outer tube assembly (#1) and install the collar (#6).2. Place the 2nd stage tube (#3) inside the 3rd stage tube (#2) and install the collar (#7).3. Re-thread the rod end (#13) onto the 1st stage tube (#4) and put the 1st stage tube (#4) into thecylinder. Be careful not to damage the seals while installing each tube.4. Thread the rear cap (#23) onto the cylinder and tighten the hex set screw (#26).Operating Conditions•The maximum operating pressure must not exceed 2500 PSI.•The contamination level of the oil must not exceed 16/13/10 from the ISO standard 4406. •The acceptable temperature range is -40° F to 200° F.Formula for Calculating the Initial Required Cylinder Force to Lift a Load:A = the distance from the center of the load to the center of the dump body hinge pin (inches)B = the length from the center of the cylinder base pin to the center of the dump body hinge pin (inches)Load (lb.) x A /B = Initial required cylinder force (lb.)Example:50,000 (lb.) x 85"/166” =25,602 lb. = Initial required force (lb.)B = The length of cylinder base pin to body hinge pin D = Dump Angle CoefficientB X D = Approximate Required StrokeExample:166(B) X 845(D)= 140 Approximate Required Stroke•When the cylinder is not in use it should be fully retracted to prevent the chromed cylinder shaft from becoming damaged.•Always store the cylinder inside to protect it against harsh weather conditions.•Fill the cylinder with oil to prevent internal corrosion caused by air condensation. Tilt the cylinder to make sure that all seals are completely in contact with the oil to avoid any prematuredeterioration of the seals.•Cover any unpainted part with a rust inhibitor to avoid corrosion.•Regularly grease the trunnion pins. The time between greasing will be dependent on the amount the cylinder is used. Improper lubrication will result in the pins wearing prematurely.•For replacement parts and technical questions, please call Customer Service at 1-800-222-5381. •Not all product components are available for replacement. The illustrations provided are a convenient reference to the location and position of parts in the assembly sequence.•When ordering parts, the following information will be required: item description, item model number, item serial number/item lot date code, and the replacement part reference number. •The distributor reserves the rights to make design changes and improvements to product lines and manuals without notice.Northern Tool and Equipment Company, Inc.

When the soldering temperature exceeds specifications, the switch may fall apart.5. Do not use switch in the environment of high humidity ，because such anenvironment may cause the leakage current between the terminals.6. More than the rated load may cause fire, so do not use more than the load7. In the circuit ，switch should not be near or directly connected with the magneticcomponent solder joints (for example: relays, transformers, etc.).8. To prevent damaging IR and PT, please make ESD protection, for example:wearing a conductive wrist strap or antistatic gloves during production process, or grounding machinery etc.。
