WARNING!
Improper operation and maintenance of this machine can
be hazardous and could result in serious injury or death.
Operator and maintenance personnel should read this
manual thoroughly before beginning operation or
maintenance.
Keep this manual in the storage compartment to the rear of
the operator's seat, and have all personnel involved in
working on the machine read the manual periodically.
Some actions involved in operation and maintenance of the
machine can cause a serious accident, if they are not done
in a manner described in this manual.
The procedures and precautions given in this manual apply
only to intended uses of the machine.
If you use your machine for any unintended uses that are
not specifically prohibited, you must be sure that it is safe
for any others. In no event should you or others engage in
prohibited uses or actions as described in this manual.
DOOSAN delivers machines that comply with all applicable
regulations and standards of the country to which it has
been shipped. If this machine has been purchased in
another country or purchased from someone in another
country, it may lack certain safety devices and
specifications that are necessary for use in your country. If
there is any question about whether your product complies
with the applicable standards and regulations of your
country, consult DOOSAN or your DOOSAN distributor
before operating the machine.

Learn the Signal Words Used with the
Safety Alert Symbol
The words "CAUTION," "WARNING," and "DANGER" used
throughout this manual and on decals on the machine indicate
degree of risk of hazards or unsafe practices. All three degrees
of risk indicate that safety is involved. Observe precautions
indicated whenever you see the Safety Alert "Triangle," no
matter which signal word appears next to the "Exclamation
Point" symbol.
SAFETY ALERT SYMBOL
Be Prepared - Get to Know All Operating and Safety
Instructions.
This is the Safety Alert Symbol. Wherever it appears in this
manual or on safety signs on the machine you should be
alert to the potential for personal injury or accidents.
Always observe safety precautions and follow
recommended procedures.
CAUTION!
This word is used on safety messages and safety labels and
indicates potential of a hazardous situation that, if not
avoided, could result in minor or moderate injury. It may
also be used to alert against a generally unsafe practice.
WARNING!
This word is used on safety messages and safety labels and
indicates potential of a hazardous situation that, if not
avoided, could result in serious injury or death. It may also
be used to alert against a highly unsafe practice.
DANGER!
This word is used on safety messages and safety labels and
indicates an imminent hazard of a situation that, if not
avoided, is very likely to cause death or extremely serious
injury. It may also be used to alert against equipment that
may explode or detonate if handled or treated carelessly.

Safety precautions are described in SAFETY from page -11 on.
DOOSAN cannot predict every circumstance that might involve
a potential hazard in operation and maintenance. Therefore the
safety messages in this manual and on the machine may not
include all possible safety precautions. If any procedures or
actions not specifically recommended or allowed in this manual

SWING BEARING
MAINTENANCE
Operating Recommendation
The service life of the swing bearing may be extended if a
conscious, daily effort is made to equalize usage over both ends
of the excavator. If the excavator is used in the same operating
configuration day in and day out (for example, with the travel
motors always under the counterweight, or with the attachment
over one side of the machine more than the other), the bearing's
service life could be reduced. Taking a few minutes in the middle
of each work shift to reposition the excavator, to work the
opposite end of the bearing, will provide a payoff in terms of
more even, gradual rate of wear and extended service life.
Measuring Swing Bearing Axial Play
Periodic, regular checks of bearing displacement should be
made at least twice a year. Use a dial indicator. Push the
attachment against the ground to lift the excavator off the ground
and take measurements at 4 points, 90° apart, around the
circumference of the bearing (Figure 1).
Record and keep all measurements. Play in the bearing should
increase minimally from one inspection to the next. Eventually,
however, as the bearing begins to approach the limit of its
service life, clearance increases become much more
pronounced and the actual measured play in the bearing could
exceed twice the value that was measured when the machine
was new.
Measuring Bearing Lateral Play
When vertical checks are made, the side to side play in the
bearing can be checked by fully retracting the arm and bucket
cylinders and extending the tip of the bucket as far forward as it
will go. With the excavator parked on a flat, level surface and the
bucket tip just off the ground, push against the bucket sideways
to take up all of the lateral clearance in the bearing. (Less than
100 lb. of force should be required to move the bucket over all
the way.) Check lateral play in both directions and record the
values. When the bearing is beginning to approach the end of its
service life, measured lateral clearance should start to show
larger and larger increases.

Swing Bearing Basic Operation
The swing bearing, which connects the upper structure with the
lower structure, consists of a inner ring, outer ring and ball
bearings. During swing movement, power from the swing motor
is transferred to the pinion by planetary gears connected to
gears on the inner ring, which is fixed in the undercarriage. Ball
bearings turn the outer ring.
Rebuilding Swing Bearing
1. Remove tip of tapered pin (1, Figure 3) using grinder and
tap lightly to remove debris.

3. Lift outer ring and check that inner ring can move freely.
See Figure 5, if not, replace seal (3, Figure 4) and/or seal
(4, Figure 4).
4. Turn inner ring and use magnet bar (1, Figure 6) to remove
steel balls (2).
5. Turn inner ring and use wire (1, Figure 7) to remove
retainers (2).

6. Assemble in reverse order of disassembly and then adjust
the gap between the steel balls and retainers using the
following guidelines: Assemble steel ball, retainer (A) and
retainer (B) to bearing; if gap is too wide, adjust by moving
steel balls or by replacing one of the retainers.

relieve any pressure from accumulators.
7. Set safety lever on "LOCK" position.
8. Turn key to "O" (OFF) position and remove from starter
switch.
9. Hang a maintenance warning tag on controls.
10. Disconnect negative (-) battery cable leading to frame from
battery.
11. Tag and disconnect hoses from swing motor (1, Figure 3).
Plug and cap hoses and ports to prevent contamination
from entering hydraulic system or component.
12. Remove drain plug (3, Figure 3) from elbow (8) and drain
oil from reduction gearbox (5, Figure 3).
13. Reassemble drain plug (3) to elbow (8) and disconnect
hose (2, Figure 3) from reduction gearbox (5).
14. Disconnect grease lubrication line (7, Figure 3) from
reduction gearbox (5).
15. Remove twelve bolts and washers (4, Figure 3) holding
swing reduction gearbox (5) to frame.
16. Using a suitable lifting device, sling swing motor (1, Figure
3) and remove swing motor and reduction gearbox (5) as
an assembly from unit.
NOTE: There are two alignment pins (6, Figure 3), on
reduction gearbox flange.
