Changing The Hydraulic Fluid - Toro 22308 Operator's Manual

Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected
into the skin must be surgically removed within
a few hours by a doctor familiar with this form
of injury or gangrene may result.
• Keep your body and hands away from pin
hole leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks, never use your hands.
11. Check the fluid level in the hydraulic tank (refer to
Checking the Hydraulic Fluid) and add fluid to raise
the level to the mark on the dipstick. Do not over
fill the tank.
12. Close the rear access cover.
