Lift maintenance for REDATS two-post lifts – what to check and when?
A two-post lift is one of those machines that operate almost daily. Without it, neither diagnostics nor basic repairs can really move forward. And if it jams or starts leaking? That’s downtime — along with delays and losses. Not to mention frustrated customers who don’t care that “something isn’t working.”
That’s why servicing your lift shouldn’t be treated as a chore, but as a regular part of taking care of your equipment. It helps you avoid unexpected failures and keep your workflow smooth.
Let’s start with the key question…
How often should you service your REDATS two-post lift?
There’s no one-size-fits-all answer — the frequency of service checks depends mostly on how intensively the lift is used. But if your REDATS two-post lift works daily, it’s worth following a routine based on the manufacturer’s recommendations.
Below is a checklist you can use as a practical service schedule:
| Interval | What to check |
| Daily | – Visual inspection of chains (check for any damage) – Check for possible leaks in hydraulic hoses and connections Listen for proper operation of safety locks |
| Weekly | – Make sure all moving parts operate smoothly – Inspect the overall condition of safety systems – Check the oil level in the reservoir – Test the tension of synchronization cables (when squeezed toether by hand, the cables shouldn’t come closer than 2–3 cm) – Check the tightness of anchor bolts |
| Monthly | Lubricate all moving parts Inspect and lubricate steel cables Lubricate the sliders inside the lift columns Visually inspect welds for any cracks Check if the lifting arms are bent or damaged |
| Yearly | Drain the oil reservoir and assess the oil condition Clean and flush the oil filter Perform a full inspection of the structural components and safety mechanisms Conduct a load test (to confirm safe lifting operation) |
Rule of thumb: It’s always better to check too often than too rarely — especially since many failures give early warning signs. Identifying issues at an early stage helps avoid serious damage and expensive downtime.
Most common maintenance mistakes – and how to avoid them
When servicing a lift, just like with any other workshop task, mistakes can happen. It’s normal – stress, routine, or fatigue can easily lead to oversights. But some mistakes show up more often than others, and they can cost you time, money, and nerves. Here are three of the most common ones – and how to steer clear of them:
- Using the wrong type of grease
Not every “workshop grease” is suitable for lifts.
Too thin? It’ll drip off in no time.
Too thick? It’ll collect dust and turn into sandpaper. And those sliders aren’t getting greased just for looks.
Remember!
Use grease recommended by the manufacturer – ideally water-resistant and high-adhesion.
- Ignoring early signs of wear
Is the lift making strange noises? One arm moving slower than the other? That’s not just “character” – that’s a warning sign.
Remember!
It could be a worn cylinder, loose pins, a hydraulic leak, or a problem with cable tension. Or maybe it’s just dry sliders rubbing against the column. The sooner you act, the lower the risk of serious failure.
- Skipping anchor bolt checks
It’s just a few bolts in the concrete – but they’re holding up the entire lift and the vehicle on it. If they come loose… you really don’t want to find out the hard way.
Remember!
Check the torque and condition of the anchor bolts regularly. It takes a minute and could save your equipment – or much more.
When to call a technician – and when you can handle it yourself
Not every issue requires a service call. Many things can be handled on your own — as long as you know what you’re doing and you’re not violating the warranty.
What can you do yourself?
- Lubricate pins, rollers, cables, and sliders
- Check the oil level in the reservoir
- Tighten any loose bolts, nuts, or anchor fixings
- Clean guide rails and moving components
- Replace worn-out rubber lifting pads
When not to DIY?
- Hydraulic cylinder leak or oil leaking near the pump
- The lift doesn’t respond to control buttons — could indicate an electrical issue
- Unusual sounds from the motor or hydraulic system
- Damaged piston rod or jammed lifting arms
- Safety locks not engaging or releasing properly
In these cases — don’t take the risk. An “eyeball fix” could end up making things worse (and more expensive).
What about the warranty?
If your lift is still under warranty, check the terms carefully. In most cases, tampering with the electrical or hydraulic systems without prior consultation voids the warranty. When in doubt — contact your supplier first.
FAQ – Frequently Asked Questions
- How often should I lubricate moving parts and sliders?
Usually every 2–3 months. If the lift is used intensively and on a daily basis — even more frequently.
Apply the grease evenly along the full length of the screws, and make sure to clean off any dirt or old grease beforehand.
- Can I use WD-40 instead of proper grease?
No. WD-40 is a penetrating fluid, not a lubricant. It can help with stuck components, but it’s not suitable for everyday maintenance.
- What if the lift lowers slower than it used to?
In cold weather, oil gets thicker — which can slow down the lowering process.
But if it’s warm? Check the lubrication between the sliders and the columns.
Remember: sliders are located at all four corners of the column, and each surface needs to be properly greased.
- How can I check if the cables are properly tensioned?
The easiest method is visual: both arms should rise evenly and stop at the same height.
If one side “lags” or stops higher — a cable may be loose.
Don’t adjust it blindly — consult a technician or refer to the technical documentation.
Summary
Regular lift maintenance isn’t just paperwork or a box to tick — it brings real benefits:
- lower risk of breakdowns and costly downtime,
- longer equipment lifespan — with no nasty surprises,
- safer working conditions — for you and your whole team.
We get it — maintenance often drops to the bottom of the to-do list in a busy workshop.
But ignore it too long, and it will come back to bite you.
Good luck — and stay safe out there!
