Printed in Sweden
The CA152 is one of Dynapac’s light vibratory rollers. It is available in STD, D (smooth
drum) and P, PD (padfoot) versions respectively. The P, PD version has its greatest
range of application on cohesive material and disintegrated rock.
All types of base courses and sub-bases can be compacted, and the interchangeable drums, from
D to PD and vice versa, provide even greater versatility in the choice of application.
This manual describes the cab and safety-related accessories.
Other accessories, such as the compaction meter, tachograph and field computer, are
described in separate instructions.

2CA152 M152EN3
Read through the entire manual before
starting any maintenance operations.
Ensure good ventilation (air extraction) if the
diesel engine is run indoors.
If the engine cover’s gas struts are
disengaged and the cover is raised to its
upper position, block the cover so that it
cannot fall down accidentally.
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.

raise the engine hood to its fully open position. Ensure
that the red safety catch on the left gas-spring is en-
gaged.
If the engine cover’s gas struts are disen-
gaged and the cover is raised to its upper
position, block the cover so that it cannot
fall down accidentally.
Check that level of the coolant is between the max. and
min. marks.
Danger of scalding. Take great caution if
the radiator cap must be opened while the
engine is hot. Wear protective gloves and
goggles.
Fill with a mixture of 50% water and 50% anti freeze.
See lubricant specification and in the engine manual.
Flush the system every other year and
change the coolant. Ensure also that air can
flow unrestricted through the radiator.

Replace or clean the air cleaner’s main filter if
the warning lamp on the instrument panel lights
up when the diesel engine is operating at full
speed.
Undo the three locking braces (1). Then pull off the
cover (2) and pull out the main filter (3).
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.

Check the tire pressures using a pressure gauge.
If the tires are filled with fluid, the air valve (1) must be
in the “12 o’clock” position during pumping.
The relevant tire pressures are given under the heading
“Specifications”.
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
Nm (350 lbf.ft). Check both wheels and all the nuts.
(Applies only to new machine or recently fitted wheels.)
Check the safety manual that accompanies
the roller before filling the tires with air.
Never work under the roller with the engi-
ne running. Park on a level surface, chock
the wheels and press the parking brake
control.
Open the engine hood while the unit is running and look
at the sight glass (1) to make sure that no bubbles are
visible on the dryer filter.
Always push the parking brake knob.
The filter is located on the left side in the front of the
engine compartment. If bubbles are visible through the
sight glass, it is a sign that the level of refrigerant is too
low. If so, stop the unit. There is a risk of damage to the
unit if it is run with insufficient refrigerant.

gears at 9 o’clock.
Wipe clean and remove the level plug (1) and check
that the oil level reaches the lower edge of the plug
hole. Top off with oil to the right level if the level is low.
Use transmission oil according to the lubricant
specification.
Clean and screw in the plug.
Check the oil level in the same way in the rear axle’s
other planetary gear.

Position the roller on a flat surface so that the filler plug
(1) and number plate (2) on the right side of the drum
are straight up.
Oil level should reach up to the sight glass (3).
Top off as required through the filler plug (1) halfway on
the sight glass.
Clean the magnetic filler plug (1) from any metal parti-
cles before refitting it.
See lubricant specification for the right grade of oil.
Do not overfill with oil, risk of overheating.

Place the roller on a level surface. Switch
the engine off and push in the reserve/
parking brake knob for all checking and
adjustments on the roller, unless otherwise
specified.
Check that air can flow freely through the radiators (1)
and (2).
A dirty radiator should be blown clean with compressed
air, or alternatively cleaned with a high-pressure washer.
Blow or wash the cooler in the opposite direction to that
of the cooling air.
Be careful when using a high-pressure washer
– do not place the nozzle too close to the
radiator.
Use protective goggles when working with
compressed air or a high-pressure washer.
