 Repeated skin contact with used hydraulic oil can cause skin
damage and other bodily harm!

off hydraulic oil that has come into contact with the skin.
 Danger of scalding! The hydraulic reservoir is pressurised.
Hot hydraulic oil may spurt out and cause scalding.
Wear rubber gloves and hold the oil drain tray underneath the

your body.
