One of Dynapac's medium heavy vibratory soil compactors is the CA280.
It is available in a solely wheel-driven version and in a wheel-and-drum-driven version,
called CA280D.
All types of base courses and reinforcement courses can be compacted to considerable depth.
The cab and safety-related accessories are described in this manual.
Other optional items are described in separate instructions.

Safety instructions – Personal safety
Special caution – Machine or component damage
The safety manual, which accompanies each
machine, must be studied by each operator of
the roller. Always follow the safety rules and
do not remove the manual from the roller.
This manual contains instructions concerning operation
and use of the roller. For information regarding care and
maintenance, see the manual, “MAINTENANCE, CA280".
When starting up and driving a cold machine,
which implies cold hydraulic fluid, the braking
distance will be longer than normal until the
machine reaches normal working temperature.

SAFETY INSTRUCTIONS (Read the Safety Manual also)
1. The operator must be familiar with the contents of the OPERATION MAN-
UAL before starting the roller.
2. Make sure that all instructions in the MAINTENANCE MANUAL are fol-
lowed.
3. Only trained and/or experienced operators may drive the roller. Passen-
gers are not allowed on the roller. Remain seated during all operation.
4. Never use the roller if it is in need of adjustment or repairs.
5. Board and leave the roller only when it is stationary. Use the grips and
railings that are provided. Always use a ”three-point grip” - both feet and
one hand or one foot and both hands - when boarding or exiting the machine.
6. The ROPS (Roll Over Protective Structure) should always be used when
the machine is operated on risky ground.
7. Drive slowly in sharp bends.
8. Avoid driving at an angle on slopes; drive straight up or down.
9. When driving close to unsafe edges or holes, make sure that at least two
thirds of the drum width is firmly on material that has already been com-
pacted.
10. Make sure that there are no obstacles in the direction of travel, on the
ground or overhead.
11. Drive extra carefully on uneven ground.
12. Use the safety equipment provided. The seat belt must be worn on ma-
chines fitted with ROPS.
13. Keep the roller clean. Clean dirt and grease from the operator’s platform
without delay. Keep all signs and decals clean and clearly legible.
14. Safety measures before refueling:
– Stop the engine.
– Do not smoke.
– No naked flame in the vicinity.
– Ground the nozzle of the filling device against the tank to prevent sparks.
15. Before repairs or service:
– Place chocks against the drums/wheels and against the strike-off blade.
– Lock the articulation if required.
16. Hearing protectors are recommended if the noise level exceeds 85 dB(A).
The noise level may vary depending on what material the machine is oper-
ating on.
17. Make no changes or modifications on the roller that could affect safety.
Changes may only be made following written consent by Dynapac.
18. Do not use the roller until the hydraulic fluid has reached its normal work-
ing temperature. Braking distance can be longer than usual if the fluid is
cold. See starting instructions in the OPERATION MANUAL.

SAFETY WHEN DRIVING
Slopes
Fig.2 Tippingangleonside slopes
Max 20°
or 36%
Driving near an edge
At least
2/3
Fig.1 Position of drum when driving near
an edge
When you drive near an edge, at least two thirds of the
drum width must be on solid ground.
Remember that the machine’s center of
gravity is displaced outward when you
steer to one side. For example, it shifts to
the right when you steer to the left.
The ROPS (Roll Over Protective Structure)
is always recommended when driving on
slopes or insecure ground.
Where possible, avoid all driving
across a
slope. Instead, drive up and down on slop-
ing ground.
The tilting angle is measured on a hard, level surface
with the machine stationary, steering angle zero, vibra-
tion switched OFF and all tanks full. Remember that
loose ground, steering of the machine, vibration
switched ON, driving speed and raising the center of
gravity (for example, with accessories) may cause the
machine to topple even on a smaller slope than that
stated here.
To leave the cab in an emergency, release
the hammer located on the rear right post
and break the rear window.

Replace the seat belt (1) if it shows signs of
wear or has been subjected to severe force.
Check that the rubber elements (3) on the
platform are intact. Worn elements will impair
comfort.
Ensure that the anti-slip (4) on the platform is
in good condition; replace with new anti-slip if
friction is poor.
If the machine is fitted with a cab, make sure
that the door is closed when in motion.

CA280 O280EN1
STARTING
Starting the engine
Set the forward/reverse lever (20) in neutral. The
engine can only be started with the lever in neutral.
Set the amplitude selector (13) for Low/High vibration to
mode O.
Set the revs control (16) to the idling mode.
Turn the starter switch (2) to mode I. The preheating
lamp (2) lights if the engine needs preheating before
starting, ie, wait until the preheating lamp goes out
before turning the starter switch to start.
Do not run the starter motor too long. If the
engine does not start immediately, wait a
minute or so before making a new attempt.
Warm up the diesel engine with the engine speed
control at the idling setting for a few minutes, or for a
longer period if the ambient air temperature is below
+10°C (+50°F).
Check while warming up that the warning lamps for oil
pressure (9) and charging (7) are out. The warning
lamp (8) for the parking brake shall still light.
When starting up and driving a cold machi-
ne, ie, cold hydraulic fluid, the braking
distance will be longer than normal until
the fluid reaches normal working tempera-
ture.
Ensure that ventilation (evacuation) is
adequate if the engine is run indoors. ie,
danger of carbon monoxide poisoning.
Start gas may not be used because the
diesel engine is fitted with an electric
preheating device in the intake tube.

DRIVING
Under no circumstances may the machine
be operated from the outside. The operator
must remain seated inside the machine
during all operation.
Move the revs control lever (16) upwards and latch it at
its limit, engine speed should now be about 2300 rpm.
Ensure that the steering is working properly by turning
the steering wheel once to the right and once to the left
while the roller is stationary.
Ensure that the area in front of and behind
the roller is clear.
Pull up the reserve/parking brake knob (5)
and check that the warning lamp for the
parking brake is out. When starting the
roller on a slope, be prepared that it may
begin to roll.

Check occasionally while driving that no lamps light. If
the oil pressure lamp lights, stop the roller and the
engine immediately. Check and remedy any fault; see
also the maintenance manual and the engine manual.
If the warning lamp (11) for the air cleaner
lights during operation (at full engine revs), the
main filter must be cleaned or replaced; see
Maintenance Manual.
Set the High/Low speed selectors (14) and (15) to the
desired mode, see decal on the control panel.
Max. speeds
Low drum/Low rear axle = 5 km/h (3 mph)
High drum/Low rear axle = 6 km/h (3.7 mph)*
Low drum/High rear axle = 9 km/h (5.5 mph)*
High drum/High rear axle = 16 km/h (10 mph)*
* (with optional accessory only)
The High/High mode may only be used for
transport runs on an even surface.
Carefully move the forward/reverse lever (20) in the
desired direction of travel. Speed increases as the
lever is moved farther from the neutral position.
Speed must always be regulated with the
forward/reverse lever and never by changing
speed of the engine.
Test the reserve brake by pressing the
reserve/parking brake knob (5) while the
roller is running slowly forward. Stop the
roller and identify the fault if the brake
does not work.
