Hey guys, it\u2019s Jake here from your go-to towable scissor lift supplier. I get it\u2014when you\u2019re running a job site, the last thing you want is a mid-shift breakdown because your lift\u2019s hydraulic oil ran low. I\u2019ve seen too many guys skip checking the oil level and end up stuck hauling a broken machine back to the yard instead of finishing that warehouse ceiling job or tree trimming route. Today, I\u2019m walking you through exactly how to check the oil level in your towable scissor lift\u2014no fancy tools, no confusing jargon, just the stuff I\u2019ve taught my own techs and our customers over the last 8 years. Towable Scissor Lifts<\/a><\/p>\n

<\/p>\n

First off, let\u2019s get one thing straight: this isn\u2019t a car. A towable scissor lift\u2019s oil is hydraulic, not engine oil, and if you mix those up, you\u2019re in for a way bigger headache. Most of our models use a hydraulic reservoir that keeps the scissor arms lifting smoothly, and low oil here is the #1 reason for slow lifts or total shut-downs. Before you even touch the cap, you gotta prep the lift right\u2014skip this step and your reading\u2019s gonna be garbage. Here\u2019s what I always tell folks: shut the lift off, lower the scissor arms all the way down until they\u2019re fully collapsed, set the parking brake, and chock the wheels if you\u2019re on uneven ground (even a tiny tilt throws off the oil level). I once had a guy test it on a sloped driveway and come back saying the \u201clevel was fine\u201d before his lift died 2 hours later\u2014don\u2019t be that guy. Also, wait 5 minutes after shutting it off; the oil needs to drain back into the reservoir, not be sitting in the lines.<\/p>\n

Okay, now let\u2019s find the reservoir. This is the part where people get lost, so let\u2019s make it easy: on most of our towable scissor lifts, the reservoir is right near the engine (or the power unit, for electric models) on the side of the machine, usually marked with a bright yellow or blue cap\u2014we even add a little \u201cHYD OIL\u201d sticker to it so you don\u2019t guess wrong. No sticker? Just follow the big rubber hoses that run to the scissor arms\u2014they connect straight to the reservoir, so that\u2019s your spot.<\/p>\n

Time to actually check the level. Most reservoirs have two marks on the dipstick (attached to the cap) or a sight glass on the side\u2014we use both on our newer models to cover everyone\u2019s preference. If it\u2019s a dipstick type: twist the cap off, pull the dipstick out, wipe it clean with a rag (no, wiping it on your jeans doesn\u2019t count\u2014you\u2019ll get dirt in there), stick it all the way back in until it\u2019s seated, then pull it out again. You\u2019re looking for oil that covers both the \u201cMIN\u201d and \u201cMAX\u201d lines\u2014if it\u2019s below MIN, that\u2019s your problem. If it\u2019s a sight glass, just peer through the plastic window; the oil should sit right between the two small notches or lines printed on the glass. Pro tip: on some older models, the sight glass can get gunked up, so wipe it off first so you don\u2019t misread it.<\/p>\n

Now, what if it\u2019s low? Don\u2019t just pour any old hydraulic oil in there. We specify 10W-30 hydraulic fluid for all our towable scissor lifts\u2014you can\u2019t use regular motor oil or gear oil. Gear oil\u2019s too thick, motor oil breaks down fast in hydraulic systems, and using the wrong stuff will wreck the pump and cost you thousands in repairs. To add oil, first wipe the reservoir cap area with a clean rag to keep dirt out (contamination\u2019s the #2 killer of hydraulic lifts after low oil), then pour the oil slow\u2014don\u2019t overfill it, that\u2019s just as bad as underfilling. Overfilled oil can foam up, which cuts down on pressure and makes the lifts slow or jerky. Add a little, check the level, repeat until you\u2019re right between MIN and MAX.<\/p>\n

Wait, hold up\u2014are there different checks for gas vs. electric models? Yep, and I wanna clarify that because a lot of people mix them up. Gas-powered towable lifts have an engine too, so you might see two separate caps: one for hydraulic oil, one for engine oil. Electric models don\u2019t have an engine, so their reservoir is just the one we mentioned earlier, no second dipstick to mess with. Also, electric lifts don\u2019t get as hot as gas ones, so their oil level might hold a little longer, but still check it every 50 hours of use\u2014same as gas models.<\/p>\n

How often should you check it, anyway? This is a question we get all the time. If you\u2019re using your lift every single day on a job site, check the oil level at the start of every week. If it\u2019s sitting in your yard for a week between jobs, check it before you tow it out\u2014you don\u2019t wanna get to the job, unhitch the lift, and realize you\u2019re low. Also, do a quick check if you notice anything off: lifts going slow, making a grunting noise when you raise them, or the scissor arms only going up halfway. 9 times out of 10, that\u2019s low hydraulic oil.<\/p>\n

Now, let\u2019s talk about common mistakes I see: first, checking the level with the scissor arms partially up. That\u2019s like checking your car\u2019s oil while it\u2019s running\u2014you\u2019re not getting the right reading. Second, overfilling. I\u2019ve had guys add 2 quarts because they thought \u201cmore is better\u201d and end up with foamy oil, which burnt out their pump in 3 months. Third, not using the right fluid. A customer of mine last year used transmission fluid because he \u201chad a jug laying around\u201d and had to replace the whole hydraulic system\u2014cost him $1,800. Don\u2019t do that.<\/p>\n

What about if you keep needing to add oil? That\u2019s a red flag, not a normal thing. If the level keeps dropping, you\u2019ve got a leak somewhere\u2014check the hoses, the connections, the reservoir seal, or the pump. A tiny, slow leak might not be noticeable until the oil\u2019s almost gone, so if you have to top it off every week, hit up our tech team, and we\u2019ll help you track it down.<\/p>\n

Quick recap to make sure you don\u2019t forget: 1. Prep: lower scissor arms fully, shut off, wait 5 mins, chock wheels if uneven. 2. Locate the hydraulic reservoir (bright cap, near lift hoses). 3. Check level: dipstick between MIN\/MAX, sight glass between notches. 4. Top off with 10W-30 hydraulic fluid, don\u2019t overfill. 5. Check every week, or before each tow if you use it sporadically.<\/p>\n
