This document is an operator's manual for Craftsman Professional Hydraulic Bottle Jacks, specifically models 50284 (12 Ton Capacity) and 50285 (20 Ton Capacity). The manual provides essential information regarding safety, assembly, operation, maintenance, and parts for these devices.
Craftsman Professional Hydraulic Bottle Jacks are designed primarily for lifting loads, not for sustaining them. They are suitable for lifting loads ranging from 12 tons to 20 tons, depending on the specific model's rated capacity. These jacks are intended for vertical use and, after lifting, require immediate support of the load with appropriate means, such as jack stands. They are also suitable for use in appropriately rated and designed vertical or bench press structures. The manual explicitly states that these jacks are not appropriate for lifting or positioning construction trailers, houses, or other building structures.
The manual provides a table of specifications for both models:
