The proper and safe lubrication and maintenance
for this machine, recommended by DOOSAN, are
outlined in the OPERATION & MAINTENANCE
GUIDE for this machine.
Improper performance of lubrication or
maintenance procedures is dangerous and could
result in injury or death. Read and understand the

5. Use steps and grab handles (if applicable) when
mounting or dismounting a machine. Clean any mud or
debris from steps, walkways or work platforms before
using. Always face machine when using steps, ladders
and walkways. When it is not possible to use the
designed access system, provide ladders, scaffolds, or
work platforms to perform safe repair operations.
6. To avoid back injury, use a hoist when lifting
components which weigh 23 kg (50 lb.) or more. Make
sure all chains, hooks, slings, etc., are in good
condition and are of the correct capacity. Be sure
hooks are positioned correctly. Lifting eyes are not to
be side loaded during a lifting operation.
7. To avoid burns, be alert for hot parts on machines
which have just been stopped and hot fluids in lines,
tubes and compartments.
8. Be careful when removing cover plates. Gradually
back off the last two bolts or nuts located at opposite
ends of the cover or device and pry cover loose to
relieve any spring or other pressure, before removing
the last two bolts or nuts completely.
9. Be careful when removing filler caps, breathers and
plugs on the machine. Hold a rag over the cap or plug
to prevent being sprayed or splashed by liquids under
pressure. The danger is even greater if the machine
has just been stopped because fluids can be hot.
10. Always use tools that are in good condition and be
sure you understand how to use them before
performing any service work.
11. Reinstall all fasteners with same part number. Do not
use a lesser quality fastener if replacements are
necessary. Do not mix metric fasteners with
standard nuts and bolts.
12. If possible, make all repairs with the machine parked
on a level, hard surface. Block machine so it does
not roll while working on or under machine.
