POTENTIAL HAZARD
Hydraulic fluid escaping under pressure
can penetrate skin and cause injury.
WHAT CAN HAPPEN
Fluid accidentally 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.
HOW TO AVOID THE HAZARD
Keep body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
Use cardboard or paper to find hydraulic
leaks.
Replacing the Hydraulic Filter

After the first 8 operating hours.
After every 200 operating hours.

prevent all hydro fluid from draining out.
A. Place drain pan under filter, remove the old
filter and wipe the filter adapter gasket
