STARTING THE ENGINE Z 8641 - Z 11441
The Z 8641 - Z 11441 tractors are currently
fitted with glow plugs.
1. Insert the key into the key switch.
Check turning off the PTO switches
on the right pillar of the tractor cab
2. Depress the clutch pedal.
3. Shift the main gearshift lever and the
reverse run shift lever to the neutral
positions.
4. Set an increased supply of fuel (ap-
prox. 3/4 maximum supply).
5. Turn the key to the “I“ position. A yel-
low light switches ON at the instru-
ment dashboard for signaling the
proper glowing operation
.
6.
Wait until the glowing signal light
switches off (the time depends upon
the temperature of cooling liquid).
In case the glowing signal light in-
stead of switching on just flashes,
there is a failure in the glowing
system. Despite of than the start
of the engine is possible but with-
out glowing plug operation. Have
the failure signaled repaired in the
professional service
center.
7. Turn the key to the position “II“
(start).
8. As soon as the engine starts, release
the key. Do not keep cranking for
more than 15 sec.
9. After the engine start, gradually re-
duce the fuel supply for avoiding the
unnecessary engine operation at
high speed.
INDICATING THE GLOW PLUG
SYSTEM FAILURE Z 8641 - Z 11441
The failure of glow plug system is indi-
cated by flashing the glow plug lamp.
- If the glow plug lamp flashes 1x within
a second with the stopped engine so
the engine glowing system works in an
emergency regime similarly like at low
temperatures, regardless the cooling
liquid temperature.
- If the glow plug lamp flashes 2x within
a second with the stoped engine so
glowing system does not work.
- If the glow plug lamp flashes perma-
nently with running engine the glow
plug regulator failed and glowing was
not finished. The failure must be im-
mediately repaired otherwise the bat-
tery will be discharged.
