MAINTENANCE
USE WARNING TAG DURING SERVICE
Alert others that service or maintenance is being
performed and tag operator’s cab controls - and
other machine areas if required - with a warning
notice.
Warning tags for controls are available from
DOOSAN
distributors; see Figure 25.
CLEAN BEFORE INSPECTION OR
MAINTENANCE
Clean the machine before carrying out
inspection and maintenance. This prevents dirt
from getting into the machine and also 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 also there is 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 non-slip 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) (1, Figure 26). If
water gets into the electrical system, there is danger that it will cause defective operation and
malfunction.
Pick up any tools or hammers that are laying in the work place, 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 work
place is left untidy, you may trip or slip and suffer injury.
