Make sure the fuel tank is filled up.
Before starting, first operate the circuit breaker button
(F1) at the right side of the control panel (open right-
hand service door first).
To start, the start/stop button (S) is switched to
position ”I”, the green fuel ON lamp (H1), the red
charge indication lamp (H3) and preheat lamp (H2)
go on (preheat lamp only, if ”cold start” option is
installed). After preheating, the preheat lamp goes
out. Push the start/stop button in position ”
”. 20
sec. (60 sec. for XAHS 186 Dd) cranking, 1 min. rest
(= a cycle). Max. 3 cycles are allowed. The starter
motor will set the engine in motion. Lamps H1 and
H3 will go out as soon as the engine has been started.
After the start/stop button is released, it automatically
springs back to position ”I”.
Run the engine a few minutes at no-load to warm up.
When the engine is running smoothly, press loading
valve (LV) and release as soon as pressure starts to
build up.
Shutting down is simply done by pushing the start
button in the ”0” position.
The control panel in addition indicates receiver
pressure (PG) and accumulated operating hours (P1).
Fault situations and protective devices (Also refer
to chapter Problem solving):
•
The starter motor is protected against prolonged
starting.
(max. cranking time: 20 sec. (60 sec. for XAHS
186 Dd)).
•
A fault which occurs with the engine, either
alternator voltage (too low), coolant temperature
too high, oil pressure too low or fuel level too low
will always and immediately cause the engine to
cut out and one of the control lamps H3, H5, H6,
H7 or H8 to light up.
•
When the outlet temperature of the element
becomes too high, a thermocontact will also
switch off the unit immediately.
Control lamp H4 will light up.
•
The control lamps will remain on untill the unit
has been reset (start button switched to position
”0”).
DURING OPERATION
Regularly carry out following checks:
1. That regulating valve (see section Main Parts,
RV) is correctly adjusted, i.e. starts decreasing the
engine speed when reaching the preset working
pressure in the receiver.
2. Check the air filter vacuum indicators (see section
Main Parts, VI). If the yellow piston reaches the
red marked service range, replace the filter
element. Reset the indicators by pushing the reset
button.
Never push the start button when the
engine is running.
When the engine is running, the air
outlet valves (ball valves) must always be
in a fully opened or fully closed position.
The doors must be closed during
operation and may be opened for short
periods only.
