Prepare For Safe Operation
— Check the fuel and hydraulic systems. Have leaks
repaired and fill to proper level.
— Check all exposed hydraulic components for leaks,
routing problems or damage. Report worn or
damaged components.
WARNING!
Diesel fuel and hydraulic fluid under
pressure can penetrate the skin or eyes and cause
serious injury, blindness or death. Fluid leaks under
pressure may not be visible.
Use a piece of cardboard
or wood to find leaks, not your hand. Wear a face
shield or safety goggles for eye protection.
If fluid is
injected into the skin, it must be removed within a few
hours by medical personnel familiar with this type of
injury. (See page 46,
Hydraulic System Hazards
.)
— Check the cooling system.
WARNING!
Prevent possible injury from explosive release
of hot fluids.
Allow the radiator to cool before checking
the fluid level
. (See page 45,
Cooling System Hazards.
)
— Keep radiators and coolers clean and free of oil,
grease, dirt, debris and moisture.
— Make sure all doors, guards and covers are in place
and secured properly.

Prepare For Safe Operation
Check The Machine (continued)
— Check the tracks for broken or damaged pins,
bushings, and other parts.
— Check the tracks for proper tension adjustment
according to manufacturer’s instructions.
— Check the tracks for damage or wear. Replace badly
worn or damaged tracks.
— Check the slew/swing brake for proper operation.
— Inspect working and other lights for proper operation.
— Inspect boom, arm and attachment for wear and
damage.
— Make sure fire extinguishers are fully charged and in
good working order.
Check Attachment And Coupler Installation
When changing buckets or installing attachments, follow
the manufacturer’s instructions for proper maintenance
and coupling. Make sure all connectors are securely
fastened. Tighten all bolts, nuts and screws to torques
recommended.
Check the attachment coupler and the attachment for
wear and hydraulic leaks before coupling the
attachment.
Before operating, ensure that quick-coupler pins or
wedges are fully engaged and visibly locked to the
attachment.
WARNING!
Avoid possible crushing injury.
Failure to
properly secure the attachment to the machine
coupler can allow the attachment to come off and
could result in death or serious injury.
(See page 17,
Quick-coupling Device Safety
