OPERATION
Preparation before operation 1. Before operation, check that all bolts are fastened tightly, and the ball head rod is secured. 2. Be sure that the tires are free of defects such as cracks and bulges, and the tire pressure is
kept at 30±2psi (2.1±0.1kg/cm2). 3. Be sure the battery is charged in full, and check whether all switches are operated
effectively. 4. Perform no-load test run, to confirm that the Swivel wheel rotates flexibly and entire unit
moves forward and backward freely. 6

5. Be sure the towed trailer weighs less than1620kgs/3600Lb, and tongue weight is less than 270kgs/600Lb.
6. The towing road is required to be flat, with an uphill angle of less than 4°. This equipment is not equipped with a brake device, so it cannot be parked on a ramp.
Selection of ball head position

C A

B

1. In order to exert the maximum traction force of the dolly and ensure sufficient friction between the wheels and the ground, please select a reasonable hitch ball position according to the usage scenario. As shown in the figure, when driving in direction D, please toggle the ball head adjusting lever to position A, and when driving in direction R, please toggle the ball head adjusting lever to position B.
Traction procedure

2. The height of the dolly’s hitch ball can be adjusted (Figure A), or the hitch ball can be directly installed on the main bracket (Figure B). The range of the ball head height is 16.7-24.5. When installing the trailer, always ensure that the connecting rod is parallel to the ground. Any inclination will affect the traction efficiency and even pose safety hazards (Figure C).
1. First, approach the dolly near the trailer’s hitch ball cover, and adjust the height of the hitch ball according to the height of the cover, so that the height of the hitch ball is slightly lower than that of the cover. Move the dolly so that the hitch ball is concentric with the Z axis of the cover, and slowly lower the trailer through the elevator, so that the cover is fully engaged with the hitch ball. After confirming the reliable connection between the hitch ball and the cover, lock the safety hook.
