TRACTOR OPERATION
E224 E225 E226
SERVICE BRAKES
Foot brakes are of disc, wet, hydrauli-
cally actuated, double pedal type with
automatic pressure compensator.
Both brake pedals must be
latched together on the move.
Use unlatched pedals to brake
the right or left wheel separately
when working in terrain and field
at low travelling speed only.
Note: When driving downhill in sharp de-
scent with a trailer or semi-trailer being
equipped with air or hydraulic brakes, it is
necessary to apply the service brake al-
ready from the beginning of the downhill
drive!
When braking with one brake
pedal, the trailer brakes are not
actuated!
AIR BRAKES OF TRAILERS AND SE-
MI-TRAILERS
Control of air brakes of trailers (semi-
trailers) is performed in such manner that
the brake effect of both vehicles is syn-
chronized.
When driving with the hitched
trailer or semi-trailer, the service
brake pedals must be connected
together and secured with latch!
When braking with one brake
pedal, the trailer air brakes do
not operate.
Note: At pressure drop, the relief valve
puts secondary appliances (differential
lock, disengagement of front driving axle)
out of operation.
AIR PRESSURE DROP WARNING
LIGHT
The red indicator light located on the
dashboard indicates the air pressure
drop below the critical value of 450 kPa.
Tractor with a braked trailer or
semi-trailer must not continue to
drive when the air pressure drops
below the critical value of 450
kPa in the air system, until the air
pressure increases.
