CA150 is Dynapac’s light vibratory soil compactor. Available in STD, D (smooth

drum) and P, PD (padfoot) versions. The P, PD version has its widest range of

application on cohesive material and rockfill materials.

All types of supporting and reinforcement courses can be compacted, and the

interchangeable drums, ie, D to PD and vice versa, give enhanced versatility in

the choice of application.

The cab and safety-related accessories are described in this manual. Other accessories,

such as the compaction meter, etc. are described in separate instructions.

SAFETY INSTRUCTIONS (Read the Safety Manual also)

The operator must be familiar with the contents of the OPERATION

MANUAL before starting the roller.

Make sure that all instructions in the MAINTENANCE MANUAL are

followed.

Only trained and/or experienced operators may drive the roller. Passen-

gers are not allowed on the roller. Remain seated during all operation.

Never use the roller if it is in need of adjustment or repairs.

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.

The ROPS (Roll Over Protective Structure) should always be used when

the machine is operated on risky ground.

Drive slowly in sharp bends.

Avoid driving at an angle on slopes; drive straight up or down.

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 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

operating 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. Avoid using the roller before the hydraulic fluid has reached its normal

working temperature. Remember that the braking distance will be longer if

the fluid is cold. See starting instructions in the OPERATION MANUAL.

CA150 O150EN3

SAFETY WHEN DRIVING

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.

At least

2/3

Slopes

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

lever is moved toward neutral. In addition, multi-disc

brakes in the rear axle act as a parking brake and are

activated when the reserve brake knob (5) is pressed in.

To brake in an emergency, press the reser-

ve/parking brake knob (5), hold the stee-

ring wheel firmly and be prepared for a

sudden stop.

After braking, restore the forward/reverse lever to

neutral and pull up the reserve/parking brake knob.
