DESIGNED FOR OFF-ROADThe engine manufacturerShibaura has specialized in designing compact dieselfuel engines since 1951.
TRIED AND TESTED S773L-CIt is a simple and reliable 3-cylinder direct injection dieselengine. It supplies 13.6 kW at2400 rpm and delivers a torqueof 62.4 Nm at 1900 rpm.
BETTER PERFORMANCE, SAME CONSUMPTIONPiston average speed is 6.48mps only. Consumption is thesame as the 25VXL model.
TWO DIESEL FUEL FILTERS Two filters are mounted
in series to keep diesel fuelclean. The second one also
features a separator with tapfor water drain (warning light
on dashboard). The re-activation
of the system is performed by means of an electric pump.
The engine is supplied by the Japanese ShibauraMachinery Corporation which produces morethan 100,000 engines per year in four plants. The S773L-C model is produced in Japan

Parallel radiators EASY CLEANING On the newcompact excavator 27V4, coolant and hydraulic oil radiators are easyto access and easy to clean as theyare not mounted in series. Cooler is secured to a perimetral structurethrough elastic supporting blocks.
ENVIRONMENT-FRIENDLYDISCHARGERadiators are located in a locked compartment. A tap connected to a discharge pipe allows
coolant to be discharged.Maintenance is carried out
without wasting a single drop.
PLASTIC FANThe cooling fan has been
studied to reduce noiseemissions. It only works
when engine is on and it isprotected by an apposite
grid on the side where dailychecks are carried out.
On the front side (whichcan be accessed removing
a guard), it is possible to access the tensioning
belt which can be adjustedthrough the alternator.

The 27V4 excavator is available in both versions. It is the smallest model of a modularproject which has resulted in six machines whose operating weight ranges from 2.7 t to 6 t. The cab is entirely manufactured in Italy and it is the same in all models
FOPS, TOPS, ROPS The model with canopy has thesame set-up as the version withcab. The latter includes howeverthe cab heating as standard. Thenew console has analog warninglights and digital operating hourscounter. Warning lights in theround pictures indicate the two-speed mode activation and the wrong machine starting(safety lever down). Moreover,the engine overheating andthe presence of waterinside the diesel fuel are also signalled.

SMART & SUSTAINABLE PLANT
NEW PRODUCTION LINE A revolution has occurred in the KATO IMER plant in San Gimignano (certified ISO 9001).Since July 2013, the new compactexcavators production line is inoperation. This has resulted in a revisedspaces allocation, thus optimizing the already existing minidumperproduction line and creating the newskid loader production line as well
as a storage area at service of all the three production lines. Quality control
is now completely computerized and it is carried outvia tablet devices.
