FUTURE REFERENCE

The CA121 is a 4-ton and the CA141 is a 5-ton vibratory roller designed for compaction operations in
pipe trenches, on road shoulders and in cramped spaces in connection with refilling work. The rollers

are also suitable for repair work on dams, power stations, parking lots and airfields.

The CA121 and CA141 are each available in two versions, D and PD. The smooth drum version with

drum drive (D) gives good maneuverability even on very steep slopes. The PD version, equipped

with pads and drum drive, is especially suitable for the compaction of silt and clayey soils.

We reserve the right to change specifications without notice.

SAFETY MANUAL

Each operator of the roller must study the
safety manual, which accompanies each
machine. Always follow the safety rules
and do not remove the manual from the
roller.

GENERAL

This manual contains instructions for the operation and
use of the roller. For care and maintenance, see the
”MAINTENANCE, CA121/141” manual.

CALIFORNIA

Proposition 65 Warning

Remember that when you start and drive a
cold machine, the hydraulic fluid is cold
and the braking distance will be longer
than normal until the machine reaches
normal working temperature.

Diesel engine exhaust and some of its
constituents are known to the State of
California to cause cancer, birth defects,
and other reproductive harm.

SAFETY INSTRUCTIONS (Also read the safety manual)

1. The operator must be familiar with the contents of the OPERATION
MANUAL before starting the roller.

2. Make sure that all instructions in the MAINTENANCE MANUAL are
followed.

3. Only trained and/or experienced operators may drive the roller.
No passengers are 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. A ”three-point grip” is always recommended when boarding or
leaving the machine—either both feet and one hand, or one foot and both
hands in contact with the machine.

6. Always use the Roll Over Protective Structure (ROPS) when the machine
is used 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
compacted.

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
machines 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.
– Don’t 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 drum/wheels and against the strike-off blade.
– Lock the articulation if necessary.

16. Hearing protectors are recommended if the noise level is higher than 85
db(A).
The noise level will vary depending on the surface you are working on.

17. Do not make any changes or modifications on the roller that could affect
safety. Changes may only be made with Dynapac’s written consent.

18. Do not use the roller until the hydraulic fluid has reached its normal
working temperature. Braking distance will be longer than usual when the
fluid is cold. See the starting instructions in the OPERATION MANUAL.

SAFETY WHEN DRIVING

Driving near an edge

At least

2/3

Fig. 1 Drum position 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 moves to
the right when you steer to the left.

Slopes

Max 20°
or 36%

Fig. 2 Tipping angle on side slopes

ROPS is always recommended when dri­ving on slopes or insecure ground.

Wherever possible, avoid driving across a
slope. Instead, drive up and down on slo­ping ground.

The tipping angle is measured on level, hard ground
and a stationary machine. Steering angle zero, vibra­tion 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 (as with accessories) may cause the machine
to topple even on a smaller slope than specified here.

SAFETY (OPTIONAL)

Strike-off blade

Fig. 3 Strike-off blade

The operator must make sure that nobody
is in the working area during operation.

Retract the strike-off blade to transportation
mode at the end of each working period.

Always lower the blade to the ground
before leaving/parking the roller.
