The base of the jack measures approximately 4 x 4 inches. If this answer does not resolve your issue, please contact us again for assistance.

Product information does not mention if a manual is included. It describes the jack as having a slow release function for safety and states it is made of durable steel with a paint finish that resists oil and dirt.

According to the product description, it is made of high-grade steel with a lead-free paint finish that resists oil, grease, and dirt for easy cleaning.

Product information does not explicitly mention if the piston ram can be replaced. However, it states the piston-ram is treated and polished to resist skiving.

While the product information doesn't explicitly mention compatibility with other brands, its universal fit type suggests it can work with most engine hoists. However, I would recommend consulting experts or the manufacturer to ensure compatibility and proper usage.
