4.1 Rope Installation

Follow these steps to correctly install the rope:

1. Connect the connector to the main hanging hole.
2. Turn on the side panel switch.
3. Open the side panel.
4. Load the rope into the device as shown in the diagram.
5. Close the cover.
6. Ensure the release handle is in the locked position.

4.2 Connecting the Electric Drill

Connect a suitable electric drill to the electric drill connection port (11) for powered operation. Ensure the drill meets the specified torque range of 50-150 N·m and is a brushless type without impact function.

4.3 Backup Safety System

A backup safety system is mandatory when using this equipment for lifting or lowering. It is recommended to use a fall arrester (self-locking device) or mechanical rope grab that complies with relevant standards.

WARNINGS:

• The slack in the backup safety system should be minimized to reduce fall impact force.
• The backup safety system should have some elasticity to cushion the fall impact force.
• The load being lifted or lowered must be within the allowed range of the backup safety system. Overloading poses a safety risk.
• There should be sufficient clear height below the backup safety system to prevent impact with obstacles or the ground during a fall.

5. Operating Instructions

5.1 Lifting (Ascending)

The device supports both manual and electric lifting.

• Manual Lifting: The product can be used as a one-way pulley to manually lift heavy objects.
• Electric Lifting: Connect an electric drill. The drill should rotate counter-clockwise to provide power for lifting heavy objects.

WARNINGS:

• When lifting, ensure the release handle is always in the locked position to prevent falls.
• After lifting to the desired position, immediately lock the rope before removing the electric drill to prevent internal ratchet lock failure and subsequent falls.

5.2 Descending

5.2.1 Descent Preparation

1. Ensure the rope is correctly installed.
2. Check that the release handle is in the locked position.
3. Wrap the rope control end around the friction hook with maximum friction and lock it.

5.2.2 Descent Steps

1. Quickly pull the release handle all the way down with your left hand, keeping it in the release position.
   Note: Pull the handle quickly; do not pull it slowly. When unlocking the handle, the internal ratchet disengages, and the rope wheel instantly becomes a two-way pulley. Therefore, before pulling the handle, ensure the rope is wrapped around the friction hook to achieve sufficient friction. The heavier the descent weight, the more turns of rope are required.
2. Slowly unwrap the rope from the friction hook with your right hand. During unwrapping, keep a firm grip on the rope control end. Do not let go.
3. Once sufficient friction is achieved, begin a slow descent. During descent, maintain control of the rope control end with your right hand. Do not let go.
4. To pause the descent, wrap the rope around the friction hook with maximum friction and lock it, then move the release handle to the locked position.
5. In an emergency, you can quickly release the handle completely, allowing it to spring back to the locked position, which will stop the descent quickly. However, frequent use of this method is not recommended as it can cause impact.

WARNINGS:

• If there are obstacles within the operating range of the release handle, it may prevent it from automatically springing back to the locked position, posing a fall risk.
• If there are obstacles within the operating range of the release handle, it may restrict its movement, preventing it from unlocking for descent.
• Ensure your hands are not in a position where they could be caught or injured during operation.

5.3 Rope Retrieval

The electric lifting method can be used for quick rope retrieval.

6. Maintenance

6.1 Pre-use Inspection

Before each use, inspect the product, accompanying ropes, other connecting components, and the backup safety system. Only proceed with use if all components are functioning normally.

• Check the product for deformation, corrosion, cracks, severe wear, sharp surfaces. Discontinue use if any are found.
• Check the cleanliness of the rope wheel, friction post, and friction hook. Grease will reduce friction, potentially causing falls. Sand will accelerate wear.
• Inspect the rope for broken strands, damaged sheath, localized thickening/thinning, bulges/depressions, severe fuzzing, excessive hardening/softening, tangles, knots, dirt, or contact with substances (oil, acid, alkali, unknown chemicals) that could weaken the rope. Replace the rope if any safety hazards are present.
• If the equipment exhibits significantly increased gear noise, abnormal shaking, inability to lift, unstable operation, or jamming, it may indicate excessive wear of bearings or gears. Discontinue use immediately.
• Before formal use, perform at least one test lift and descent with a loaded item. It is recommended that the lifting height does not exceed 30 cm. Listen carefully for a deep and even "click" sound from the ratchet. If the sound is abnormal, the equipment may be faulty, and use should be stopped immediately.

6.2 In-use Inspection

• During lifting, closely monitor the equipment for any abnormalities as described in the pre-use inspection.
• Observe if the rope is sliding in the rope wheel during lifting. Continuous sliding can generate high temperatures and damage the rope.
• During descent, closely monitor the temperature of the friction post and friction hook.

6.3 Periodic Inspection

A comprehensive inspection should be performed every 6 months. In addition to the pre-use inspection items, check the following:

• Inspect friction components. If wear is excessive, the product should be retired or sent to the manufacturer for replacement.
• The product's interior is lubricated and maintenance-free within its nominal lifespan. If necessary, add high-temperature resistant grease. (Note: Users can remove the square cover (at the electric drill connection port) to replace the input shaft, then add grease. Repairs or replacements of internal host parts require returning the product to the factory.)
• Inspect the moving parts and springs of the release handle. If stuck, clean thoroughly and apply lubricant.
• Check all fixing bolts. If they protrude from the mounting surface, they are loose. Tighten them. If bolts repeatedly loosen, apply a small amount of low-temperature anaerobic adhesive and tighten, then allow to cure before use.
• Inspect the input shaft gear. If wear is excessive, it should be replaced. Refer to the official website for details.

6.4 Storage and Maintenance

• Store the product in an environment between 10°C and 30°C (50°F and 90°F), avoiding water, humidity, corrosive liquids, and corrosive gases. Avoid heavy pressure and falls from height.
• During transportation, use a padded bag or case to protect the product from severe impacts, dirt, and dust.
• After each use, wipe the product clean with a damp cloth (using clean water), then air dry. Do not expose to direct sunlight. Avoid prolonged contact with corrosive liquids like sweat, which can cause corrosion.
• The gears, rope wheel, entry rope guide wheel, and exit rope guide wheel can be replaced if worn, provided the safety margin of the ratchet (internal locking component) is sufficient.
• Regularly inspect the moving parts of the handle, entry and exit rope guide wheels, etc. Clean dirt and add lubricating oil.
• Except for replacing the input shaft gear and rope wheel, any modification, part replacement, or repair of this product must only be performed by the manufacturer. Unauthorized disassembly, modification, or repair is strictly prohibited.

7. Troubleshooting

• Increased Gear Noise, Abnormal Shaking, Inability to Lift, Unstable Operation, or Jamming: These symptoms may indicate excessive wear of bearings or gears. Discontinue use immediately and contact support.
• Abnormal Ratchet Clicking Sound: If the clicking sound of the ratchet is not deep and even during operation, the equipment may be faulty. Stop use immediately.
• Rope Sliding in Rope Wheel: If the rope slowly slides in the rope wheel when a nominal minimum diameter rope and maximum working load are applied, with the release handle locked and no tension on the rope control end, the rope wheel should be replaced, the unit sent back to the factory for repair, or the entire machine retired.
• Handle Obstruction: If the release handle is obstructed and cannot move freely or return to the locked position, check for and remove any obstacles. This is a critical safety concern.

8. User Tips

• Always prioritize safety. Double-check all connections and ensure the backup safety system is correctly deployed before any operation.
• Regularly clean your equipment, especially the rope path, to prevent premature wear and maintain optimal friction.
• Familiarize yourself with both manual and electric operation modes in a safe, controlled environment before attempting real-world applications.
