As far as i'm aware, you can just start working it as soon as its started. Personally i would take it easy for the first few minutes to give the oil a chance to warm up. You may notice slower hydraulic action until it has warmed up but this won't cause damage.

One way to speed up the heating of the oil is to hold your foot down on the lift arm peddle or pull back on the tilt ram peddle or put the aux hydraulics into detent. This will make the relief valve open and the oil will heat up much faster if you just leave the machine sitting there waiting for it to heat the oil up.

my manual stated to let it warm up for at least five minutes and that's when it's warm out. i live in Minnesota, hell's about to freeze over next week do to low temps. I let my 753 run for at least five, best yet to just let it run untill it's up to operating temp. then I'll usually 'strech it out' move all/use all the hydro circuits for full sweeps slowly to warm up the fulid. keep in mind cold metal doesn't flex or bend; it cracks so take it easy, utill the thing moves and sounds like it does in july.

I never even thought about the metal frame.... you make a good point there.
This is the time that i'm glad the temperature never gets below 0 degrees C here.
Mind you, i would love it to be cooler than the 34 odd degree days we are currently having, and they will soon reach high 30's to low 40's..... I hope poor santa doesn't melt before he finds my house.

Another note on Cold starts if you live in an area that get cold/below freezing consider using sythetic lubricants not only do they offer better protection against thermanl breakdown, but the actually flow/ pour when it very cold preventing dry starts. I run mobil1 5w-40 synthetic for my crankcase, and I use synthecic grease on all pivot points. One of the guys I do work for uses lithuium on his JD240. it was creaking and howling last night when ever you had a load in the bucke. The grease had frozen making it uselss as far as a lubricant. FYI Lithium Grease is water based, it is [email protected] Especially in cold weather. Note on Synthetic oil, Make sure the stuff you use is rated for use in diesel engines look for a CF/CG API rating, The C part of CF or CG means combustion ignition.

We put a loop hose in the aux. couplers and turn them on to warm the hyd. oil up. That way your not blowing the relief.
