So now you are aware of when to check a forklift’s fluid level based on its operation, unusual noise, and high fluid temperature. Here is a step-by-step tutorial on how to properly check the level of hydraulic fluid.
1. Get your dipstick ready.
For diverse forklift models, the majority of original equipment managers utilize the same dipstick. For instance, the same dipstick is frequently used by forklifts with pneumatic tires and cushions. With cushion forklifts, simply use the side of the dipstick designated C1, C2, C3. For pneumatic forklifts, utilize the side denoted with P1, P2, and P3. To choose which mark to use, we advise you to thoroughly review your operator manual or get advice from a forklift specialist.
2. Parking on the ground floor
Before monitoring the fluid level, it’s crucial to make sure the forklift is not parked on an incline or an uneven surface.
3. Maintain a regular fork position.
The forks are then lowered to the ground, being careful not to tilt them either forward or backward. Some of the fluid will remain in the lift cylinders when they are tilted or raised, giving an incorrect readout.
4. Pull the dipstick to quickly determine the fluid level.
5. Use the fluid that the manufacturer has advised.
All that’s left to do is use the specified fluid to guarantee a quick and effective performance.
To check the condition of your hydraulic fluid, we advised you to proactively monitor the forklift’s performance speed, operation noise, and fluid temperature. Your forklift must have routine fluid checks, forklift inspections, and filter replacements to operate at peak efficiency. If you have any inquiries about forklift service, please don’t hesitate to contact our helpful staff.

In a Toyota forklift, where do you put the hydraulic fluid?
The majority of manufacturers advise changing the hydraulic oil in forklifts every 1,000 hours of operation. You should check your fluid levels before to doing this.
Make sure your forklift is parked levelly first. Set the parking brake after lowering the forks to the ground.
Remove the reservoir cover from the forklift’s hydraulic fluid. Check the fluid level using a dipstick. You must change the forklift hydraulic oil if it is low.
You’ll need to be aware of the appropriate fluid type for this. There are various kinds of hydraulic oils for forklifts, including synthetic, petroleum-based, and water-based fluids. Consult your forklift handbook to decide the kind you require.
When the forklift is operating, do you check the hydraulic fluid?
Hydraulics are essential to the lifting and steering functions of forklifts. The lifting and steering capacities of a forklift are guaranteed by the reservoir’s adequate supply of hydraulic fluid. Leaks and spills result from the tank having too much fluid in it.
The pre-shift inspection procedure for the forklift operator includes checking the hydraulic fluid. The dipstick may have a variety of marks, thus it’s important to know which mark to use while measuring.
The same dipstick is frequently used across vehicles by OEMs. For instance, Toyota 7 Series trucks with masts varying from single to triple stages utilize the same dipstick for pneumatic tire and cushion trucks. P1, P2, and P3 are marked on one side, and C2 and C3 are marked on the other. Pneumatic tire forklifts are utilized on the P side, and trucks with cushion tires are used on the C side. The raise stages on the mast are indicated by the numbers 1, 2, and 3. To find out which mark to use, consult your owners manual or your neighborhood dealer.
- Park on a level surface.
- The prongs should be lowered to the ground level and not tipped backward or forward. You won’t get an accurate reading if they are tilted or raised since some hydraulic fluid will be in the lift cylinders.
- Consult your owner’s handbook to find the location of the hydraulic tank if you are unsure of where the dipstick is.
- Check the level by removing the dipstick.
- Take care when incorporating liquids.
- use the fluid that the manufacturer recommends, please. The improper ingredients will produce extremely subpar outcomes.
The majority of manufacturers advise changing the hydraulic oil in a forklift every 1,000 hours of use. Regular fluid checks, filter changes, and routine inspections will keep your machinery operating properly.

The engine architecture of your forklift will have a significant impact on the oil you choose when performing maintenance. While diesel engines require oil with additional additives, a typical sit-down counterbalance forklift can use 5W-30 or 10W-40.
Forklift Oil Viscosity
The viscosity of the forklift oil at lower temperatures is indicated by the first number in the description. The thickness at operating, or warmer, temperature is represented by the second number. In the cooler winter conditions, a substance with less viscosity will work better.
The use of lighter oil, like 5W-30 or 5W-40, has become popular among several forklift manufacturers recently due to its benefits to fuel efficiency. The lighter the engine, the less energy and oil it requires to turn.
Manufacturer Guidelines for Forklift Oil
Guidelines for oil are provided in the forklift operator manual, but you should consider what is ideal for your application. Forklifts are designed for heavy-duty, industrial tasks. Major forklift parts may start to break down early if the oil is of poor quality or does not include the proper additives.
Our training staff at ProLift discovered that forklift parts can benefit from oil and grease that are matched to the forklift’s application. For instance, the mast pivot experiences significant pressure. Water and dirt pushed up from the ground have an impact on it as well. Wear and tear diminished once the grease used to the bushings was changed.
If so, what kind of hydraulic fluid is it?
Hydraulic fluid replacement is generally advised every 1,000 hours of operation by forklift manufacturers. Operators should follow a checklist that involves checking the hydraulic fluid tank before each shift in order to appropriately monitor levels.
How is a forklift checked?
Verify the forklift for cracks, leaks, and other obvious flaws anywhere. Avoid using your hands when inspecting the mast chains. Test the tension of the mast chain by raising the load backrest to eye level. Any tilting of the mast chains may indicate stretched or damaged rollers. The chains should be level.
How do you check the forklift’s brake fluid?
Your forklift is a significant investment and one of your company’s most useful tools. Regular fluid checks assist prevent mechanical failure and breakdown. Learn to regularly check the fluid levels in your car on your own. It won’t take long once you get the hang of it.
Although your owner’s manual specifies when fluids need to be checked, this is the bare minimum required to maintain the validity of your warranty. Make a note of the date or simply keep an eye on the fluid levels.

3. Inspect the engine oil. To avoid getting a false reading, you should check the oil after the engine has cooled down for about 30 minutes so that the oil has been drained down from the return galleries, cylinder head valleys, etc. Use the owner’s manual to find the oil dipstick’s location. Pull the dipstick all the way out, putting a finger through the loop to release any clips keeping it in place. To get a clear reading from the dipstick, clean it with a paper towel or rag. Push the dipstick firmly all the way back, as far as it will go, into the aperture. This time, fully extend it and check the oil level. Replace the dipstick in its opening after you’re finished.
4. Verify your brake fluid. For the location, check your manual or look around for a plastic reservoir like this one that is marked “brake fluid.” If your reservoir resembles this one, you can see right through the plastic to the fluid level. If necessary, clean the exterior of the vehicle. Have off the cap and take a peek inside if you still can’t see it.
Brake fluid shouldn’t be consumed by forklift. Low brake fluid may be a sign of a brake line leak or of worn brake surfaces. Have the car inspected to determine the cause if your brake fluid is low. A forklift that has low brake fluid or brake fluid leaks may be unable to stop.
5. Verify the fluid in the power steering. This reservoir will often be made of plastic. By opening the lid and adding more of the proper power steering fluid, you can read it through the walls much like you could with the brake fluid. One pair of lines may be for a hot engine and the other may be for a cold engine. Read the one that applies to the state of your forklift at the time.
6. Verify your coolant. Make sure the engine is completely cold before opening the reservoir to avoid scalding water spraying out! Most likely, the coolant will be in a reservoir up front, close to the radiator.
How can I tell when my hydraulic fluid is running low?
Very little hydraulic fluid is used by the hydraulic power unit. A leak anywhere in the system is the most frequent cause of low hydraulic fluid levels. Slicks on the floor below the leak’s location can frequently be used to detect leaks. A low fluid condition might develop from any leak that is not fixed right away.
The power unit will make a gurgling sound as the first indication. The platen will gurgle as it transitions from being fully closed to open. Slow response from the cylinders when the platen starts to move from the fully open position is another indication. You need to check your fluid level if either of these symptoms is present.
- A zinc-coated breather cap has been fitted in the X-6 reservoir. The level of the fluid will be checked at this cap, which should only be hand tight.
- Important: Only the SX-280 in its fully retracted position should be used to verify fluid levels. Retract the cylinders and then turn off the power unit before removing the black cap. Check the fluid level using a dipstick to see if it is within 1 of the reservoir’s top (you can use a rolled up paper towel as a dip stick).
- If the level is low, add fluid until it is just one inch below the reservoir’s top. Use a hydraulic fluid that is ISO32 food grade only.
What occurs if the hydraulic fluid level is low?
When a hydraulic system malfunctions, it is frequently simple to identify the symptoms, which can include high temperatures, low pressure measurements, and sluggish or unpredictable functioning. What are the most frequent reasons for hydraulic system failures, though? Most hydraulic problems have one of the following common causes, which we can identify.
Air and Water Contamination
The main reasons for hydraulic failure, which account for 80 to 90% of hydraulic failures, are air and water contamination. Both types of contamination are frequently brought on by broken pumps, system breaches, or temperature problems.
Aeration and cavitation are the two ways that air enters a hydraulic system, causing air contamination. Over time, both can seriously harm the hydraulic system by degrading the pump and its surrounding components, polluting the hydraulic fluids, and even overheating it. Despite the fact that we do not make pumps, we are aware of how important it is to be knowledgeable about these kinds of contamination and how to recognize their signs.
- Cavitation: About 9% of the dissolved air in hydraulic oil can be pulled out by the pump and explode, resulting in pump issues as well as long-term damage to the pump and other parts of the hydraulic system. If your hydraulic pump is whining, you can tell this is a problem.
- Aeration: Aeration happens when air from outside the pump cavity enters the cavity. This problem is typically brought on by weak connections or leaks in the system. When the pump is running, aeration also produces a knocking-like sound.
Another typical issue with hydraulic systems is water pollution, which is frequently brought on by system leaks or condensation brought on by temperature variations. Hydraulic parts can eventually deteriorate due to oxidation and freezing damage caused by water. Hydraulic fluid’s milky tint can be used to detect water pollution.
Temperature Problems
Too-hot or too-cold hydraulic systems might develop serious issues over time. Some of these difficulties include the symptom list below.
- Hydraulic fluid thinning due to heat can prevent lubrication and increase the likelihood of leakage.
- Oxidation of the fluid: Hydraulic fluid can thicken and oxidize under extremely hot temperatures. In addition to reducing the system’s capacity to disperse heat, this fluid thickening can lead to accumulations in the system that limit flow.
- Fluid thickening: Hydraulic oil becomes more viscous at low temperatures, making it more difficult for the oil to reach the pump. Cavitation damage can occur in systems when loads are applied before the oil reaches 70 degrees or above.
Heat buildup is typically attributed to insufficient heat dissipation, whereas too-cool systems are typically brought on by external variables.
Fluid Levels and Quality
Performance of hydraulic systems can be impacted by fluid quality and quantity. Inadequate filtration and low fluid levels can lead to air pollution, whereas fluid contamination can result in temperature issues. Leaks can make both problems worse.
It’s also crucial to use the right fluid because different hydraulic oils are suitable for different uses. Even oil choices are available that provide greater resistance to issues caused by temperature. Even some lubricants come with anti-wear and anti-foam compounds to assist guard against wear and, correspondingly, air contamination.
Human Error
Many hydraulic system issues are mostly caused by human mistake. The following are some of the most typical mistakes that could prevent your hydraulic pump from developing pressure.
- Installation mistakes: Any component in a hydraulic system that is installed incorrectly might cause serious mistakes. For instance, a pump shaft moving the wrong way could negatively effect pressure accumulation, or pipes connected improperly could cause leaks.
- Parts that are incompatible: A novice installation may combine unrelated components, leading to operational issues. A motor for a pump, for instance, might be operating above its maximum drive speed.
- Improper operation or maintenance: Some of the most frequent causes of hydraulic system damage include operating systems beyond their operational limits and neglecting to complete routine maintenance. These issues, however, are simple to resolve with updated maintenance procedures and training.
