CA 150 is Dynapac’s light vibratory soil compactor. Available in D (smooth drum) and
PD (padfoot) versions. The 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.
This manual describes the cab and safety-related accessories. Other accessories,
such as the compaction meter, etc. are described in separate instructions.

It is important that the roller is maintained correctly to
ensure proper function. It should be kept clean so that any
leakage, loose bolts and loose connections can be
discovered in time.
Make a habit of walking round the roller to check it every
day before starting the first shift – including under the
machine. This is often the easiest way of discovering any
leakage.
SPARE A THOUGHT FOR THE
ENVIRONMENT! Do not let oil, fuel and other
environmentally hazardous substances contami-
nate the environment.
This manual contains instructions for periodic attention
which should normally be carried out by the roller operator.
There are additional instructions relating to the
diesel engine, for which the manufacturer’s
instructions are detailed in the engine manual.
This is found under a separate flap in the roller’s
product binder.

promote overheating, resulting in premature wear.
When driving in extremely high or low ambient tempe-ratures, other lubricants are needed.

Never work under the roller with the engine
running. Park on a level surface. Block the
wheels securely.
It is important to consider movement of the
drum when the machine turns, ie, the scrapers
can be damaged or wear of the drum may
increase if adjustment is made closer than the
values stated.
If necessary, adjust distance to the drum as follows:
the scraper is integrated with the beam.
Loosen the four screws (2) on the frame side, then ad-
just the beam to about 20 mm (0.8 in) from the drum.
Tighten the screws.

Do not remove the safety filter (4).
If the main filter is to be cleaned, compressed air at
max. 5 bar (72 lbs/sq in) pressure should be used.
Blow up and down along the paper creases on the in-
side of the filter.
Hold the nozzle at least 2–3 cm (0.8-1.2 in) away from
the paper creases so that the paper does not tear un-
der the pressure of air.
Use protective goggles when working with
compressed air.
Dry the inside of the cover (2) and filter housing (5).
Check that the hose clamps between the filter
housing and inlet hose are tightened and that
they do not leak. Check the entire length of the
hose all the way to the engine.
Once the main filter has been cleaned a maxi-
mum of 5 times, it must be replaced.

Wipe all the nipples clean from dirt and grease.
Lubricate each nipple (1) with five strokes of the grease
gun. Make sure that grease penetrates the bearings.
If grease does not penetrate through the bearings, it
may be necessary to relieve the load on the articulated
joint with a hydraulic jack and then repeat the greasing
process.

Check both tires.
When changing the tires it is important that
both of them have the same rolling radius. This
is necessary to ensure proper functioning of
the anti-slip in the rear axle.
Check the tightening torque of the wheel nuts (2) at 470
