    Foam filled tires going flat

    I have a recently purchased 2004 snorkel tb60 manlift 22000 lb 4 wheel Drive with 4000 hours on it. Two of the four originally Factory foam filled tires look like an air filled tire that is halfway inflated. So I'm wondering if the foam can deteriorate inside, and if so is there a way to add...

    Tricks 2 pull out of soft ground

    I can't even budge this 24000 pound man lift out of the wheel ruts with my 4 wheel drive 55 horsepower tractor. And the man lift brakes are disengaged with the torque hubs disengaged. So here was one of my ideas, chain the boom end to a stationary object, like a tree or the tractor, and...

    Hydraulic high pressure gauge

    Where and what kind of hydraulic high pressure gauge that will go up to 3000 pounds should I get? It would be just for my personal use on my marklift Model 62 manlift. And the service manual said to connect it to a high pressure port, but I don't know where I would find the high pressure port...

    Boom lift Drive Wheels torque fade

    The hydraulic wheel motors turn the wheels while unloaded, but slows down and stops when load is applied. The service manual says "check planetary wheel drive to be sure engaging disc is not positioned in freewheeling." So my question is what is the planetary wheel drive, and where is the...

    Man lift safety belt

    I'm looking for advice and recommendations on how to pick a man lift safety belt. I will be using the man lift to prune tall trees. Also wondering if there are any kind of special ropes or hardwear for rope that I could use to carabine down to the ground in case the emergency boom lowering and...

    ATF when to change

    When ATF automatic transmission fluid Dexron 3 is used in place of hydraulic oil, aside from the hour meter, how do you know when it's time to change that fluid? In my case, the machine is a 1980 marklift man lift that I purchased at an auction.

    Filter indicator piston stuck

    I took the piston and spring out of this Schroeder pilot filter dirt indicator and put it in upside down and now it is stuck. I'm trying to get it out using some long tweezers and even though the piston spins around freely, I can't get enough grip on it to pull it out. I tried slamming it...

    Air in hydraulic pump at lines

    I suspect that my marklift 62 foot boom hydraulic pump may be sucking air when it starts making a loud noise when I engage any of the boom functions such as lift or extension or rotation. This happens on every function and the function will operate normal for anywhere between 2 to 5 Seconds...

    Boom lift Hillside operation

    I would like general advice on operating a boom lift on uneven ground like slopes. I live on a hillside with about a 15-degree incline and the slope indicator on my 1980 Mark lift 62 foot boom activates when the ground is over 5 degrees incline. So for example when I am just driving the Boom up...

    Hydraulic lines in boom access

    I discovered blistering on the orange NC hydraulic lines inside the Boom about 20in back from the end of the Boom. Apparently the prior owner of this machine melted the lines during a welding repair. It's a marklift 62 ft straight 3 section boom man lift. I need to be able to pull the lines out...

    Hydraulic cylinder piston nut keeper

    Any suggestion on what to do with this little punched hole to stop the nut from coming loose? I was thinking of possibly trying to just pry the edge up out of the way from the nut and hoping it would not break when I press it back down after replacing the nut. I'm guessing that Loctite on the...

    Marklift 62 torque hub engage

    I recently purchased a 1980 Marklift 62 boom lift. It was delivered with the torque hubs disengaged for transport purposes. When I reversed the cover cap on the left side drive wheel, a pin sprung to the outer position and I put the cap back on with the cap button facing out. I assume that was...
