Identify Your Floor Jack Model
Identifying your Craftsman floor jack model is the first step before refilling it. Each model may have different requirements and specifications. Knowing the exact model helps you find the right type of hydraulic fluid and instructions.
This process is simple and quick. It ensures you maintain your floor jack properly and avoid damage. Start by locating the model number on the jack itself.
Locate The Model Number
Look for a metal plate or sticker on your floor jack. This plate usually shows the model number and serial number. It is often found on the side or bottom of the jack. The model number is a mix of letters and numbers.
Write down the model number exactly as it appears. This detail helps you search for the correct refill fluid and parts. Clean the area if the plate is dirty to read the numbers clearly.
Check The Owner’s Manual
Your owner’s manual contains specific information about your floor jack model. It tells you what type of oil to use and how to refill it safely. Manuals also have diagrams and safety tips.
If you lost the paper manual, check online. Many Craftsman manuals are available on the official website. Enter your model number to find the right manual. Reading it avoids mistakes and keeps your jack in good shape.
Gather Necessary Tools And Materials
Gathering the right tools and materials is the first step to refill your Craftsman floor jack safely and correctly. Having everything ready avoids delays and mistakes during the process. This section explains which items you need and why they matter.
Choose The Right Hydraulic Fluid
Use only the hydraulic fluid recommended by Craftsman. Check your floor jack’s manual for the exact type. Using the wrong fluid can damage the jack’s seals and reduce its performance. Most Craftsman jacks require a specific jack oil or hydraulic fluid. Avoid motor oil or brake fluid, as they do not work properly in hydraulic systems.
Purchase the fluid from a trusted store or online supplier. Ensure the container is sealed and not expired. Clean fluid helps keep the jack working smoothly and prevents corrosion inside the system.
Prepare Cleaning Supplies
Clean the jack before refilling to remove dirt and debris. Dirt can enter the hydraulic system and cause leaks or damage. Gather a clean cloth, paper towels, and a mild cleaning spray. Avoid harsh chemicals that might harm the jack’s surface or seals.
Use gloves to keep your hands clean and safe. Have a small funnel ready to pour the fluid without spilling. Proper preparation ensures a neat and efficient refill process.
Prepare The Jack For Refilling
Preparing your Craftsman floor jack for refilling is a crucial step. It ensures safety and proper maintenance. Follow the right steps before adding hydraulic fluid. This helps keep the jack working smoothly and extends its life.
Position The Jack Safely
Place the jack on a flat, hard surface. Avoid soft or uneven ground. This prevents the jack from tipping over. Make sure the jack is fully lowered. Lowering releases pressure on the hydraulic system. It also makes refilling easier and safer.
Release Hydraulic Pressure
Locate the release valve on the jack. Slowly turn it counterclockwise to release pressure. Do this gently to avoid sudden fluid spills. Wait until the jack lowers completely. Check that no pressure remains before opening the reservoir. This step avoids accidents and fluid leaks.

Drain Old Hydraulic Fluid
Draining the old hydraulic fluid from your Craftsman floor jack is a key step before refilling it. This process removes dirty or worn-out fluid. Clean fluid helps your jack work smoothly and last longer.
Follow simple steps to drain the old fluid safely. Keep your workspace clean and prepare to handle the fluid carefully.
Locate The Drain Plug
Find the drain plug on your Craftsman floor jack. It is usually at the base of the hydraulic cylinder. Use a wrench to loosen it slowly. Let the fluid flow out into a container. Be careful, as the fluid may be oily and slippery.
Collect And Dispose Fluid Properly
Place a drip pan or container under the drain plug. This will catch the used hydraulic fluid. Avoid spills on the floor or ground. After draining, seal the fluid in a container. Take it to a recycling center or hazardous waste site. Do not pour it down drains or on soil.
Refill With New Hydraulic Fluid
Refilling your Craftsman floor jack with new hydraulic fluid is key to keeping it working smoothly. Fresh fluid helps the jack lift heavy loads without strain. It also prevents damage inside the hydraulic system.
Follow these steps carefully to refill the fluid correctly. Proper filling ensures your jack stays safe and reliable for a long time.
Open The Fill Port
Find the fill port on your floor jack. It is usually near the hydraulic cylinder. Use a wrench to remove the fill plug. Keep the plug safe to avoid losing it.
Make sure the jack is on a flat surface. This helps the fluid settle evenly inside. Check for any dirt around the fill port. Clean it before opening to avoid contamination.
Pour Fluid To Recommended Level
Use the hydraulic fluid type recommended in your manual. Pour the fluid slowly into the fill port. Stop pouring when the fluid reaches the right level.
Do not overfill. Too much fluid can cause leaks or poor performance. After filling, replace the fill plug and tighten it securely. Test the jack to check for smooth operation.
Bleed Air From The Hydraulic System
Bleeding air from the hydraulic system is key for a smooth Craftsman floor jack refill. Air trapped inside stops the jack from lifting properly. Removing this air restores full hydraulic pressure. This process improves the jack’s performance and safety.
Follow these steps carefully to bleed air from your Craftsman floor jack. The goal is to get rid of all air bubbles inside the system. This will make the jack work like new again.
Pump The Jack Slowly
Start by pumping the jack handle slowly. This action helps push trapped air toward the release valve. Pumping too fast can cause more air to mix inside the fluid. Take your time and keep the movement steady.
Repeat slow pumps several times. Listen for any unusual noises. The sound of air moving out means progress. Stop when the pump feels smooth and consistent.
Check For Air Bubbles
Next, check the hydraulic fluid for air bubbles. Look inside the fluid reservoir carefully. Tiny bubbles indicate air still inside the system.
If you see bubbles, keep pumping slowly. Watch the fluid until no bubbles appear. Clear fluid means the air is fully removed. This ensures your jack works at full strength.
Test The Floor Jack
Testing your Craftsman floor jack after refilling it is important. It ensures the jack works safely and correctly. This step helps find any problems early. You can fix issues before using the jack for lifting heavy objects. Follow these simple checks to test your floor jack properly.
Check Lifting Performance
Start by placing the jack under a sturdy object. Pump the handle slowly to lift the object. Notice if the jack rises smoothly and steadily. The lifting should feel firm, not weak or shaky. If the jack struggles or does not lift high, the fluid level might be low. Or, there could be air trapped inside. Repeat the pumping a few times to see if the performance improves. This step confirms the jack is ready for use.
Inspect For Leaks
Look closely around the jack’s body and hydraulic parts. Check for any wet spots or fluid drips. Leaks mean the jack’s seals may be damaged or loose. This can cause the fluid to escape and reduce lifting power. Clean the jack first to see leaks clearly. Tighten any loose fittings if you find leaks. If leaks continue, replace the damaged parts to avoid accidents.
Maintenance Tips For Longevity
Keeping your Craftsman floor jack in top shape helps it last longer. Regular care avoids problems and keeps it working safely. Simple steps can protect your jack and save money on repairs. Follow these maintenance tips to extend your jack’s life.
Regular Fluid Checks
Check the fluid level often. Low fluid can cause the jack to work poorly. Use the right hydraulic fluid made for floor jacks. Open the fill plug and look inside. Add fluid if it is below the recommended level. Avoid overfilling to prevent leaks. Clean the area before opening to keep dirt out.
Store Jack Properly
Keep the floor jack in a dry, clean place. Avoid wet or dusty areas that can cause rust. Lower the jack completely before storing it. This reduces pressure on seals and parts. Cover the jack with a cloth or tarp to block dust. Proper storage stops damage and keeps the jack ready for use.
