Practice Safe Maintenance
Inspection/maintenance work may produce hazardous
situations by contacting and/or accessing a part of body
to a moving, high pressure, and/or high temperature part
of the machine. To avoid serious personal injury or death,
follow the instructions described below.
Thoroughly coordinate the working procedures to be
taken hereafter with the co-workers before beginning
work such as inspecting/servicing the machine, or
replacing the attachment.
Safely park the machine in accordance with the
instructions for "Park Machine Safely. "
Keep the work area clean and orderly.
Attach a "DO NOT OPERATE" tag in an easy-to-see location
such as on a door or a control lever.
If moisture permeates into the electrical system,
malfunction and/or erroneous movement of the machine
may result. Do not clean sensors, cable connectors, and
the cab inside using water and/or steam.
Wait to begin to work until the engine and hydraulic oil
temperatures have cooled down to the safety range.
In case inspection/maintenance must be performed with
the engine running, be sure to appoint an overseer.
Never lubricate or service the machine while moving it.
Repair the cracked windowpane before servicing the
machine. Failure to do so may cause personal injury.
When raising the machine above the ground using the
front attachment function, maintain the angle between
the boom and the arm in the range of 90 to 110°. Never
allow anyone to enter under the machine raised with the
front attachment function.
In case working under the machine raised above the
ground is unavoidably required, securely hold the
machine with stays or blocks strong enough to support
the machine weight.
Never work under the raised bucket.
Keep all parts in good condition and properly installed.
Always use the specified tools correctly.
Always use a clean tool.
Fix any damage found immediately. Replace worn or
broken parts.
Remove any buildup of grease, oil, or debris.
When cleaning parts, use a non-combustible cleaning
solvent. Never use an inflammable fluid such as diesel
fuel, or gasoline.
