1. Environmental Control
1. Dry and Ventilated Storage
For long-term storage, choose a dry, corrosive-free environment to avoid humidity and high temperatures that accelerate oxidation.
Raise the base by at least 10 cm to ensure air circulation and prevent erosion from ground moisture.
2. Covering and Protection
When used outdoors, cover the retracted mast with a dust-proof and waterproof cover (such as PVC) to prevent rainwater accumulation.
2. Surface Treatment
1. Cleaning and Rust-Proofing Coating
Regularly wipe the mast with a neutral detergent to remove corrosive residue such as salt and sand.
After cleaning, apply rust-proof oil or wax, focusing on protecting the metal joints and locking mechanism.
2. Special Process Protection
Stainless steel or galvanized masts are preferred, as their oxide layer naturally resists rust.
For carbon steel parts, consider electroplating or spraying with an epoxy zinc-rich primer.
3. Mechanical Maintenance
1. Lubrication and Sealing
Apply high-temperature resistant grease to moving parts, such as telescopic joints and bearings, quarterly to reduce friction and corrosion. Check the seals for signs of aging and replace them promptly to prevent moisture infiltration.
2. Regular Inspections
Monthly, inspect the locking mechanism, welds, and coating integrity. If rust is found, immediately sand it and reapply rust inhibitor.
IV. Operating Instructions
Avoid use in strong acidic or alkaline environments. After contact with seawater, rinse with fresh water and thoroughly dry.
Before retracting the electric mast, ensure the mast is completely dry to prevent moisture from shorting the internal circuitry.
V. Long-Term Storage Recommendations
Retract the mast to its shortest length and store it upright in the original packaging to avoid deformation.
In extreme climates, use with a dehumidifier or desiccant.
