The JLG 600S telescopic boom lift is a widely used piece of equipment known for its reach and versatility in construction and maintenance projects. One critical maintenance task on this machine involves the removal and replacement of the telescopic cylinder, which controls the extension and retraction of the boom. This article outlines key steps, challenges, and helpful tips for successfully removing the telescopic cylinder, ensuring safety and efficiency.
Understanding the Telescopic Cylinder's Role
The telescopic cylinder is a hydraulic component essential for boom movement, allowing the operator to extend or retract the boom smoothly. Over time, seals may wear, or the cylinder may develop leaks or internal damage, requiring removal for repair or replacement.
Preparation Before Removal
Before beginning the removal, it is crucial to ensure the boom lift is securely supported and that all hydraulic pressure is safely relieved. Disconnecting the battery and following lockout/tagout procedures prevents accidental activation.
Operators have emphasized the importance of using proper lifting equipment and stabilizing the boom to avoid sudden movements that could cause injury or damage.
Step-by-Step Removal Process
Some technicians report difficulty in removing the cylinder due to corrosion or tight fittings. Applying penetrating oil and gentle tapping with a soft mallet can help loosen stubborn parts. Patience and care prevent damage to the boom or hydraulic components.
A mechanic shared a story where improper support during removal caused the boom to shift suddenly, underscoring the need for safety measures.
Post-Removal Considerations
Once the cylinder is removed, thorough cleaning of mounting areas and inspection of hydraulic hoses is recommended. Replacement cylinders should match OEM specifications to maintain system integrity.
Reinstallation follows the reverse process, with attention to torque specifications and proper hose connections to avoid leaks.
Additional Tips
Removing the telescopic cylinder on a JLG 600S boom lift is a task that requires preparation, proper tools, and safety awareness. Sharing experiences and best practices among operators and technicians helps improve procedures and reduce downtime. With careful attention, this maintenance can extend the service life of the boom lift and ensure reliable performance on the job.

Step-by-Step Removal Process
- Lower the boom to a safe, accessible position, resting it securely.
- Drain hydraulic fluid from the cylinder lines to prevent spills.
- Disconnect hydraulic hoses carefully, labeling them for correct reinstallation.
- Remove the retaining pins or bolts securing the cylinder to the boom sections.
- Use a crane, hoist, or mechanical assistance to support and slide the cylinder out of its mount, as it can be heavy and cumbersome.
- Inspect mounting points for wear or damage during removal.
