but the best one was a 3/4 inch high pressure hose on my pretince loader. absoutly covered my truck that was parked 30 feet away. :censored:[/QUOTE said:
Once while loading tree length with my 200 Serco, I forgot to uncouple my Espar engine coolant heater, when I lifted the main boom too high, I jambed a lift cylinder fitting again my coolant couplers and broke the fitting off. The boom dropped like a rock and twin 6 by 48" cylinders sprayed there contents everywhere while I frantically guided the boom and trees down between the haul truck and the wood loader.
Haul truck, loader truck and loader were all showered with hyd oil.
Another time, same loader at my mechanics shop, the young mechanic was removing a 8" outrigger cylinder. He was suppose to remove the hoses, then lossen the lockblock until it began to leak and catch the oil as gravity pulled the fold down stabilizer down.
Instead the orings held the lockblock to the cylinder and he completely removed the bolts and no seepage. So he tapped the lockblock with a hammer at which point it leaped off the cylinder and the 500lb outrigger fell, evacuating the 8" (by about 30") cylinder connected to it. Gallons of hyd oil sprayed 20 ft in the air until it hit the ceiling of the shop, then fell like rain all over the contents of the entire building.
Several hours of attempted clean up only collected the worst of it and the rest took months to wear off everything you touched.
A local slasher loader operator joked that new biodegradeable hydraulic oil was designed to be pumped from the power unit through the slasher saw motor (at about 75 gallons per minute) then "fly out in the bush" (return lines not required)
Anther wise man (Gib Erickson) at their local mill told me "never wear new cloths around hydraulic equipment, thats just begging for a oil bath":bang:
