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.

Prevent Fires

Check for Oil Leaks:
 Fuel, hydraulic oil and lubricant leaks can lead to fires.
 Check for oil leaks due to missing or loose clamps, kinked
hoses, lines or hoses that rub against each other, damage
to the oil-cooler, and loose oil-cooler flange bolts.
 Tighten, repair or replace any missing, loose or damaged
clamps, lines, hoses, oil-cooler and oil-cooler flange bolts.
 Do not bend or strike high-pressure lines.
 Never install bent or damaged lines, pipes, or hoses.
 Replace fuel hoses and hydraulic hoses periodically even
if there is no abnormality in their external appearance.
Check for Shorts:
 Short circuits can cause fires.
 Clean and tighten all electrical connections.
 Check before each shift or after eight (8) to ten (10) hours
operation for loose, kinked, hardened or frayed electrical
cables and wires.
 Check before each shift or after eight (8) to ten (10) hours
operation for missing or damaged terminal caps.
 DO NOT OPERATE MACHINE if cable or wires are loose,
kinked, etc.
 Never attempt to modify electric wirings.
