Frequently Asked Questions - 48112 Craftsman
What is the lifting capacity of the Craftsman 48112 jack?
The Craftsman 48112 jack has a maximum lifting capacity of 2.5 tons (5,000 lbs), suitable for most passenger cars and light trucks.
How do I properly use the jack to lift my car?
Position the jack under the vehicle’s designated lift point, ensure the jack is on a hard level surface, then pump the handle to raise. Use jack stands immediately after lifting.
What should I do if the jack doesn't lift smoothly?
Check the hydraulic fluid level. If low, refill with recommended AW-32 hydraulic oil. Also inspect for air in the system by opening the release valve and pumping the handle a few times.
How do I lower the jack safely?
Turn the release valve slowly counterclockwise. Lower the vehicle in a controlled manner, keeping hands clear of the jack and vehicle.
What maintenance does the jack require?
Regularly lubricate pivot points and wheels with light oil. Inspect for leaks and clean the ram. Store the jack in a dry environment.
Can I use this jack on a gravel or uneven surface?
It is not recommended. Always use on a hard, level surface to prevent tipping. If necessary, place a plywood board under the jack for stability.
What should I check before each use?
Verify the jack is fully intact, no visible leaks, handle is tight, and wheels roll freely. Test the jack by lifting slightly without load.
How do I replace the hydraulic fluid?
Remove the fill plug, tilt the jack to drain old fluid, then refill with new AW-32 hydraulic oil until just below the port. Purge air by opening the release valve and pumping.
Are replacement parts available for this model?
Yes, parts such as the hydraulic unit, handle, and saddle pad are available through Craftsman or aftermarket suppliers. Check the manual for part numbers.
What safety precautions must be taken when using the jack?
Never exceed the rated capacity, always use jack stands after lifting, keep body parts away from moving parts, and never work under a vehicle supported only by the jack.
