- Working temperature range: -15℃ to 40℃
- Lifting load limit: 250kg
- Applicable rope diameter: 9 - 12mm
- Electric drill torque range: 50 - 200N.m and above non-impact electric drill
- Dustproof/waterproof: not dustproof, not waterproof

Warning:
- If there are obstacles within the range of motion of the release handle, it may prevent it from automatically rebounding to the locked position, posing a risk of falling. It is necessary to use double rope operation and use a fall arrest system or mechanical rope gripper that meets relevant standards or is certified.
- The slack in the backup safety system should be minimized as much as possible to reduce the impact of falling; The backup safety system should have a certain degree of elasticity to cushion the impact of falling.
- The ascending or descending load should be within the allowable range of the backup safety system. Overloading may pose safety risks.
- Adequate clearance height should be left below the backup safety system to prevent collision with obstacles or the ground in the event of a fall.

Using Instructions:
- Manual lifting: Connect this product to the hanging point above, correctly install the rope, and it can be used as a one-way pulley to manually lift heavy objects.
- Electric lifting: This product only supports counterclockwise rotation of the hand drill to input power for lifting heavy objects. When the connecting hole is connected to the user's seat belt, this product can move and lift itself with the user's movement.
- When the connecting hole is connected to the hanging point, this product does not move with the user and can be used in conjunction with other pulleys (groups) to lift distant goods or personnel.

Descending:
- When the connecting hole is connected to the user's safety belt, this product can be used as a personal descent device to lower the user themselves.
- When the connection hole is connected to the hanging point, this product is used to lower goods or as a rescue and escape device to lower personnel.
- Warning: When using the electric lifting function, please ensure that the release handle is always in the locked position to prevent the lifted object or personnel from falling.

Safety Check Before Use:
(1) Check if this product has any deformation, corrosion, cracks, severe wear, sharp surfaces, etc. If so, stop using it immediately and contact the manufacturer for technical support.
(2) Check the cleanliness of components such as pulleys, friction blocks, etc. If there is grease in the friction components mentioned above, it will reduce the friction force, leading to accidental falling of goods or personnel; If there are sand particles in the friction components mentioned above, it will cause rapid wear and tear.
(3) Check whether the rope is broken, the rope skin is damaged, partially thickened, partially raised, partially depressed, severely fuzzy, excessively hard, excessively soft, tangled, knotted in the middle, or dirty with mud and sand; The usage history of the rope is clear, and it has not been exposed to substances that may weaken the performance of the rope (such as oil, acid, alkali, unknown chemicals, etc.). If any of the above situations occur, the rope should be replaced with a non safety hazard rope and the above inspection should be carried out before it can be used.
(4) If the rope is damp, the load should be reduced during lifting to prevent slipping, and the rope should be slowly loosened during descent to prevent the descent speed from losing control.
(5) If the equipment experiences significant increase in gear operation noise, abnormal shaking, inability to input power, unstable or stuck lifting work, it may indicate excessive wear of the equipment's bearings and gears. It should be stopped immediately.
(6) If the power input shaft with improved function is found to be toothed or slipping, it indicates that the power input shaft is worn out. The lifting function should be stopped immediately and the manufacturer should be contacted for technical support. The malfunction of the power input shaft does not affect the use of the descent function. Tip: Other connecting components are also necessary components of system security. Please refer to the information provided by the relevant manufacturer and conduct inspections as required.
(7) Before formal use, at least one lifting and lowering test should be conducted for the lifted goods. It is recommended that the lifting height should not exceed 30cm. Pay attention to the "click" sound emitted by the ratchet during operation to see if it is clear and loud. If the sound is abnormal, the equipment may have a malfunction and should be stopped immediately.
