(1). when several hydraulic jacks work at the same time, they should be directed by someone to make the lifting or falling simultaneously. Two adjacent hydraulic jacks shall be supported with wooden blocks to ensure that the gap is secured against sliding. (2). when using hydraulic jack, always pay attention to the sealing part and pipe joint part, and must ensure its safety and reliability. (3). hydraulic jacks are not suitable for sites where acids, alkalis, or corrosive gases are applied. Note: In order to operate correctly, all cylinders need to be connected to a solid lifting surface. The use of cylinders on sandy, clay or loose surfaces can lead to cylinder damage.

But no other holes. **Q: What type of hydraulic oil is used with the CP 700 pump?** A: #15 hydraulic oil is ok **Q: Does one hand pump work for all units? When you say, "only retracts with heavy gravity" , how much weight are you talking about?** A: Dear， we need to know what's your hand pump, for example if you want to buy the 50t jack, you need a hand pump like the product( amazon code: B06Y1HKMVC， search it on amzon , you will find it), but if you want more efficient， we advise you to choose electric hydraulic pump. About the "only retracts with heavy gravity", we are sorry, the jack doesn't need to retract with heavy gravity, it will retract by itself when the pump pressure relief, we will change our description. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/444948622-newtry-20-ton-hydraulic-cylinder-long-jack-4-stroke-porta](https://www.desertcart.vn/products/444948622-newtry-20-ton-hydraulic-cylinder-long-jack-4-stroke-porta) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
