Alright, imagine you have a big, strong toy that helps lift really heavy stuff like a super-powered robot arm. That toy is called a Hyster S30A Space saver, but in real life, it’s actually a forklift used in warehouses to move big boxes.
Now, for this forklift to move its arms up and down smoothly, it needs a special “magic juice” called hydraulic fluid. This juice helps the forklift’s muscles (which are like metal parts) work properly without getting stuck.
So in simple words, The Hyster S30A Space saver doesn’t just drink any juice. It needs the right kind to keep working like a champ. The best fluid for it is Dexron Transmission Fluid (it’s red in color!) On the other hand, Some people also use AW32 or AW46 hydraulic oil.
Why Is Hydraulic Fluid Important?
Hydraulic fluid acts like the “blood” of your forklift’s hydraulic system. It is responsible for transferring power from one part of the forklift to another. Without the right fluid, the forklift could experience issues like poor lifting performance, overheating, and even mechanical failures. That’s why choosing the correct type of fluid is crucial for keeping your machine running efficiently.

The Recommended Hydraulic Fluid for the Hyster S30A Spacesaver!
For the Hyster S30A Spacesaver, the recommended hydraulic fluid type is usually a premium quality hydraulic oil that meets certain specifications. Most experts suggest using AW32 hydraulic fluid, which stands for Anti-Wear 32. The “32” refers to the viscosity grade, meaning the thickness of the fluid at a specific temperature.

AW32 is commonly used in forklifts because it provides excellent lubrication, anti-wear protection, and operates well across a wide range of temperatures.
What Does AW32 Hydraulic Fluid Do?
AW32 hydraulic fluid plays an important role in your forklift’s hydraulic system. Here’s a breakdown of its key benefits:
- Anti-Wear Protection: AW32 helps protect the components inside the forklift from damage caused by friction.
- Temperature Control: It helps keep the hydraulic system at a proper temperature by reducing the chances of overheating.
- Smooth Operations: The fluid ensures that the lifting and tilting functions of the forklift run smoothly and efficiently.
Other Hydraulic Fluid Considerations
While AW32 is commonly used, it’s important to check your Hyster S30A Spacesaver manual for specific fluid requirements based on your climate and operating conditions. For example, if you’re working in extremely cold environments, you may need a different grade of fluid that can perform well in low temperatures.
Also, ensure that the hydraulic fluid is clean and free of contaminants. Dirty or old hydraulic fluid can cause blockages and damage to your forklift’s system. For the Hyster S30A Spacesaver forklift, the hydraulic fluid type specification typically requires the use of AW32 hydraulic oil, which is a common grade used in many forklifts for its performance and protection.

Hyster S30A Spacesaver Hydraulic Fluid Type Specifications
- Fluid Type: AW32 (Anti-Wear 32)
- Viscosity Grade: The “32” in AW32 refers to the viscosity of the fluid at 40°C (104°F), which is around 32 centistokes (cSt).
- Operating Temperature Range: AW32 hydraulic fluid works well in temperatures ranging from -20°F (-29°C) to 100°F (38°C). It offers effective performance in a wide range of temperatures, which is suitable for typical indoor and outdoor operations.
- Oil Standards: Meets the ISO 6743/4 classification for hydraulic fluids. Compatible with DIN 51524-2 standards for hydraulic oils.
- Fluid Change Interval: It’s a good practice to change the hydraulic fluid at recommended intervals, typically around 1,000 hours of operation or once a year, depending on the operating environment.
0336831 Aw32 2.5 Gallon Hydraulic Oil for Hyster!
The 0336831 AW32 2.5 Gallon Hydraulic Oil is a hydraulic fluid designed for Hyster forklifts like the S30A Spacesaver. It is AW32 grade, meaning it provides anti-wear protection and works well in temperatures from -20°F to 100°F.

Therefore, this fluid helps prevent rust, corrosion, and wear in the forklift’s hydraulic system, ensuring smooth operation and longer machine life. Simply check your forklift’s fluid levels and replace it with this oil according to the maintenance schedule.
Hyster Forklift Transmission/Hydraulic Oil – Comparison!
Hyster Forklift Transmission Oil:
- Recommended Oil: For the transmission, Hyster typically uses a multi-viscosity oil like 10W-30 or SAE 10W-30.
- Purpose: This oil helps with smooth shifting, lubrication of moving parts, and overall transmission performance.
- Frequency: Check the oil levels regularly and change it as per the manufacturer’s guidelines (usually every 1,000 operating hours or annually).

Hyster Forklift Hydraulic Oil:
- Recommended Oil: The recommended hydraulic oil for many Hyster models, including the S30A Spacesaver, is AW32 (Anti-Wear 32) hydraulic fluid.
- Purpose: Hydraulic fluid enables the forklift to perform tasks like lifting, tilting, and steering by transmitting power through the hydraulic system.
- Frequency: Change the hydraulic fluid regularly, typically every 1,000 operating hours or annually, to maintain system performance and prevent wear.
Is the Hyster S30A forklift manual????
You can find the Hyster S30A forklift manual by visiting the Hyster official website (hyster.com) or by contacting a Hyster dealer. They can provide you with the correct manual for your forklift model. You may also find it on third-party websites like ManualsLib.
What More People Want To Know?
What type of hydraulic fluid does a Hyster forklift take?
For Hyster forklifts under service contracts, you can use a universal fluid for both the hydraulic system and transmission. We recommend using Mobilfluid 424, which meets the JDM J20C specification for optimal performance and protection.
What kind of hydraulic fluid for a forklift?
For most forklifts, new models generally require hydraulic oil with a viscosity of 32 Cst or 46 Cst. However, for used forklifts, it’s better to use hydraulic oil with a higher viscosity, such as 68 Cst, to maintain smooth operation and performance.
Is universal tractor fluid hydraulic fluid?
Yes, universal tractor fluid is a type of hydraulic fluid. For example, Sinclair Universal Tractor Fluid is a high-quality hydraulic fluid made with premium base oils and anti-wear additives, offering excellent load-carrying capacity and protection in a wide range of temperatures and tough conditions.
Can you use tractor hydraulic fluid in a forklift?
Yes, you can use tractor hydraulic fluid in a forklift. Universal Tractor Transmission Oil (UTTO) is designed to lubricate components like transmissions, gears, hydraulic systems, and wet brake systems. It’s suitable for use in forklifts, as well as in earthmovers, combines, mowers, balers, and plows, but it’s not meant for engine use.
What kind of hydraulic fluid do I use?
For hydraulic equipment used indoors under normal conditions, a conventional anti-wear hydraulic oil with the right viscosity is recommended. The most common viscosities are ISO 32, 46, or 68, as they effectively lubricate and protect the system across typical operating temperatures.
What uses AW32 hydraulic oil?
AW32 hydraulic oil is commonly used in forklifts, construction equipment, and machinery requiring standard anti-wear protection.
What is the difference between AW32 and AW46 hydraulic fluid?
AW32 has a lower viscosity than AW46, making it suitable for cooler environments, while AW46 is thicker and works better in warmer temperatures.
