Diesel engine:
Cummins QSB 5.9-C
These instructions apply from:
CC 722: PIN (S/N) *63920722*
CC 722C: PIN (S/N) *64020722*
The CC 722 is a roller of the heavier category in the CC family.
The CC 722 has articulated steering and drive on both drums.
The CC 722 features high power, high capacity and high quality in extremely demanding
applications, such as building highways and airfields, with strict requirements for results and
sealed surfaces in compacting various asphalt compounds.
Separate information about accessories is available on request.

CONTENTS
Safety instructions—Personal safety.
Special caution—Machine or component damage.
Read the entire manual before starting any
service work.
Ensure that ventilation (extraction) is adequate
if the engine is run indoors.
It is essential that the machine is properly cared for to
ensure satisfactory operation. Keep the machine clean to
facilitate quick and timely detection of any leakage, loose
bolts and loose connections.
TAKE CARE OF THE ENVIRONMENT
Do not leave behind any oil, fuel or other substances that
are detrimental to the environment.
This manual contains instructions for periodic activities
that should normally be performed by the operator.
For the diesel engine, the engine manufacturer’s
instructions—found in the engine manual—also
apply. This manual is included in the product
binder.

joints when the engine is running. Danger
of being crushed.
Wipe the nipples clean from grease and dirt.
Lubricate the steering cylinder mounts (1) with two
strokes of the grease gun and the horizontal and vertical
bearings of the steering joint (2) with five strokes each.
If grease does not penetrate the bearings, relieve load
on the articulation with a jack and repeat the greasing.
Ensure that grease penetrates the bearings and leave a
little grease on the nipples to prevent dirt from entering.
Ensure that the breather holes (1) in the hydraulic
reservoir cover are not clogged. Clean the cover with
diesel oil and blow dry with compressed air as required.
Wear protective goggles when working

Battery – check
Never use an open flame when checking
the electrolyte level. Explosive gas is
generated when the alternator is charging.
Wipe the top of the battery.
Wear safety goggles. The battery contains
acid. Rinse with water if electrolyte comes
into contact with the body.
Take off the cell caps and ensure that electrolyte is
about 10 mm (0.4 in) above the plates. Check the level
of all cells. Top off with distilled water to the right level if
the level is low. If the air temperature is below freezing,
the engine should be run for a while before topping up
with distilled water, there is otherwise a risk that the
battery fluid will freeze.
Ensure that the ventilation holes in the cell cover are
not clogged. Then put the cover back on.
The cable shoes should be clean and well tightened.
Clean corroded cable shoes and grease them with
acid-free Vaseline.
When disconnecting the battery, always
disconnect the negative cable first.
When connecting the battery, always connect
the positive cable first.
Discarded used batteries properly. Batteries
contain lead, which is detrimental to the envi-
ronment.
Before doing any electric welding on the
machine, disconnect the battery ground
cable and then all electrical connections to
the alternator.

Hydraulic system
– changing the filters
Remove the filters and empty the fluid into the spill-oil
container. Discard the filters; they are disposable and
cannot be cleaned.
Ensure that the old gaskets do not remain on
the filter holders. Leakage may otherwise
occur between the new and the old sealing
rings.
Thoroughly clean the sealing surfaces of the filter
holders.
Apply a thin coat of fresh hydraulic fluid to the new filter
gaskets.
Tighten the filters by hand. First, screw on until the filter
seal lies against the filter holder. Then screw a further
half-turn.
Do not tighten the filter too hard; this could
damage the seal.
Start the engine and ensure that no hydraulic fluid leaks
from the filters.
Ensure that ventilation (extraction) is
adequate if the engine is run indoors.
(Risk of carbon monoxide poisoning.)
Check the fluid level in the sight glass (2) and top off as
required.
When you read the filter indicator, the hydraulic fluid
should be warm and the engine running at full revs.
Ensure that the air flow through the radiator is unob-
structed. Clean a dirty radiator with water or com-
pressed air. Blow the radiator in the opposite direction
to that of the cooling air. Ensure that seals and noise
absorbers are not damaged by the cleaning operation.
Wear protective goggles when working
with compressed air.
