Replace Rubber Hoses Periodically

Rubber hoses that contain flammable fluids under pressure
may break due to aging, fatigue, and abrasion. It is very
difficult to gauge the extent of deterioration due to aging,
fatigue, and abrasion of rubber hoses by inspection alone.

Periodically replace the rubber hoses. (See the page of
“Periodic replacement of parts” in the operator’s manual.)

Failure to periodically replace rubber hoses may cause a fire,
fluid injection into skin, or the front attachment to fall on a
person nearby, which may result in severe burns, gangrene,
or otherwise serious injury or death.
Avoid High-Pressure Fluids

Fluids such as diesel fuel or hydraulic oil under pressure can
penetrate the skin or eyes causing serious injury, blindness
or death.

Avoid this hazard by relieving pressure before
disconnecting hydraulic or other lines.

Tighten all connections before applying pressure.

Search for leaks with a piece of cardboard; take care to
protect hands and body from high-pressure fluids. Wear a
face shield or goggles for eye protection.

If an accident occurs, see a doctor familiar with this
type of injury immediately. Any fluid injected into the
skin must be surgically removed within a few hours or
gangrene may result.
