Maintenance - Doosan DX140R Operation & Maintenance Manual

MAINTENANCE

Warning Tag
Alert others that service or maintenance is being performed and
tag operator's cabin controls – and other machine areas if
required – with a warning notice. OSHA mandated control lever
lockout can be made with any OSHA certified lockout device and
a length of chain or cable to keep the safety lever in the fully
lowered, nonnative position.
Warning tags, for controls are available from DOOSAN
distributors.
Clean Before Inspection or Maintenance
Clean the machine before carrying out inspection and
maintenance. This prevents dirt from getting into the machine
and ensures safety during maintenance.
If inspection and maintenance are carried out when the machine
is dirty, it will become more difficult to locate the problems, and
there is a danger that you may get dirt or mud in your eyes or
that you may slip and injure yourself.
When washing the machine, do the following:
• Wear shoes with nonslip soles to prevent yourself from
slipping and falling on wet places.
• Wear safety glasses and protective clothing when washing
the machine with high-pressure steam.
• Take action to prevent touching high-pressure water and
cutting your skin or having mud fly into your eyes.
• Do not spray water directly on electrical components
(sensors, connector). If water gets into the electrical
system, there is a danger that it will cause defective
operation and malfunction.
Pick up any tools or hammers that are laying in the workplace.
Wipe up any grease or oil or any other slippery substances, and
clean the area to make it possible to carry out the operation in
safety. If the workplace is left untidy, you may trip or slip and
suffer injury.
