Using this electric powered floor crane is easy. First, make sure the batteries are fully charged. You can check the battery level using the battery level gauge. When operating, hold the ergonomic handle. Use the throttle to control the forward and reverse speeds, and the lift/lower controls to move the load up and down. In case of an emergency, the emergency reverse function can be used. Remember, the electromagnetic disc brake will activate automatically when you release the handle. For safety, always use the rigid hook with the safety latch to secure the load. When it comes to maintenance, keep the poly - on - steel wheels clean and lubricated. Check the batteries regularly and recharge them as needed. Also, make sure to follow the weight capacity limits for each model to avoid overloading and potential damage to the crane.
