The PESCO Smart Spider Powered Ascender PSJ120-20 is a high-performance industrial tool designed for efficient and safe vertical operations. To ensure optimal performance and user safety, follow the instructions and precautions outlined below.

1. Battery Installation/Replacement
   Installation/Removal:
   Press the power switch to activate the battery compartment.
   Remove the old battery and insert a new 36V lithium battery securely.
   Charging Procedure:
   Plug the 36V charger into the battery first, then connect it to a 220V power supply.
   A red charging indicator signifies active charging; a green light indicates full charge.
   Note: Limit charging time to 4–6 hours. Avoid overcharging to prolong battery life.
2. Power Management
   Switch & Display:
   Turn on the power switch to activate the voltage and battery percentage display.
   The screen cycles between real-time voltage and remaining power (e.g., 80%), providing clear visibility of energy status.
3. Rope Specifications
   Compatibility:
   Exclusive 14mm rope (supplied with the device) must be used.
   Rope features:
   High-quality, abrasion-resistant material.
   Thermal-cut ends to prevent fraying.
   Flexible yet durable thick-body design.
   Critical Requirements:
   Rope heads must be tapered using PESCO’s patented knot design for smooth entry/exit.
   Discard ropes with kinks, burns, corrosion, or looseness.
4. Operational Procedures
   Pre-Use Checks
   Inspect the machine’s casing and rope for damage.
   Verify sufficient battery voltage/power (≥20% recommended).
   Ensure the anchor point for the rope is secure.
   Setup & Usage
   Emergency Stop Release: Rotate the emergency switch clockwise (if triggered).
   Rope Loading:
   Insert the rope through the entry port only (never the exit).
   Press the ▲ UP button to auto-feed the rope.
   Attaching Loads:
   Use a D-ring carabiner to connect items to the lifting hook.
   Ascend/Descend Control:
   Use the handheld remote to adjust movement.
   Release the button to engage automatic braking.
   Performance Limits

   Max speed: ≤14 m/min
5. Safety Warnings
   Critical Prohibitions:
   Never overload beyond the specified limit.
