Perform Maintenance Safely
Prepare The Work Area
— Position the compact excavator in a level area out of
the way of other working equipment.
— Make sure there is adequate light, ventilation and
clearance.
— Remove oil, grease, ice and snow or water to
eliminate any slippery surfaces.
— Clean around the machine and work area to minimize
contamination. Clean up oil or fuel spills promptly
and dispose of the material properly.
Prepare The Machine
— Attach a “DO NOT OPERATE” warning tag to the
control levers and remove the ignition key if the
machine should not be started.
— Block the tracks.
— Release all hydraulic, water and air pressure. Lower,
lock or block all hydraulically supported components.
WARNING!
Disconnecting or loosening any hydraulic
component or a part failure can cause unsupported
equipment to drop.
Do not go under or near raised
equipment unless supported by a manufacturer-
approved support device(s).
Death or serious injury
could result from falling equipment.
— Remove only guards or covers that provide access to
the area being serviced. Replace all guards and
covers when work is complete.

Use Approved Ventilation
If it is necessary to run an engine in an enclosed area,
remove the exhaust fumes from the area with an
exhaust pipe extension.
WARNING!
Prevent possible injury.
Never work on
machinery with the engine running unless instructed
by the manufacturer’s manuals for specific service.
WARNING! Never operate any type of engine without
approved ventilation
—EXHAUST FUMES CAN KILL.
Use Jacks And Hoists Carefully
If you must work beneath raised equipment, use solid
wood blocks, jack-stands or other rigid and stable
supports. Never use concrete blocks. When using jacks
or hoists, always be sure they are adequately supported
and of adequate capacity.
Make sure the hoists or jacks you use are in good repair.
Never use jacks with cracked, bent or twisted parts.
Never use frayed, twisted or pinched cables. Never use
bent, worn or distorted hooks.
Protective Structure Safety
Do not remove or modify a protective structure
(TOPS/ROPS, FOGS/FOPS OPS) except for service.
Reinstall with manufacturer-approved fasteners before
further machine operation.
Replace a damaged protective structure. Refer to the
manufacturer’s manual for specific instructions and
inspection requirements.
