OPERATING INSTRUCTIONS
9/235HA, 10/215HA
STARTING THE MACHINE
All normal starting functions are incorporated in the key operated
switch.
1. Turn the key switch to position (1). The engine fault and compressor
fault lamps will flash.
2. Turn the key switch to crank position (3) (engine start position)
3. Release to position (1) when engine starts. The engine will now be
running at a reduced speed.
At temperatures below 32°F (0°C) or if there is difficulty starting first
time:
1. Open the manual blowdown valve fully.
2. Complete starting sequence above.
3. Close manual blowdown valve as soon as engine runs freely.
Do not allow machine to run for long periods with manual blowdown
valve open.
4. Allow the engine to reach operating temperature.
5. At this point in the operation of the machine it is safe to apply full
load to the engine.
PUSH AFTER WARM-UP
Allow the engine to reach its operating temperature and then press the
button.
At this point in the operation of the machine it is safe to apply full load
to the engine.
DUAL PRESSURE REGULATION (WHEN FITTED)
Machines which operate in excess of 7 bar (100 psi) can optionally be
fitted with a dual pressure switch inside the unit. This switch selects
between 7 bar (100 psi) and the machine rated pressure, cfm remains
nominally constant.
Starting and stopping are unaffected by the selection and during
normal running the selector switch may be safely operated.
Precautions must be taken to ensure that downstream equipment is
rated to suit the available pressure.
The pressure gauge indicates which setting has been selected.
STOPPING THE MACHINE
1. Close the service valve.
2. Allow the machine to run unloaded for a short period of time to
reduce the engine temperature.
3. Turn the start switch to the off position (0).
If the automatic blowdown valve fails to operate, then pressure must be
relieved from the system by means of the service valve(s).
EMERGENCY STOPPING
In the event that the unit has to be stopped in an emergency, TURN
THE KEY SWITCH LOCATED ON THE INSTRUMENT PANEL TO
THE
OFF POSITION (0), or push the EMERGENCY STOP SWITCH
(when fitted).
RE-STARTING AFTER AN EMERGENCY
If the machine has been switched off because of a machine
malfunction, then identify and correct the fault before attempting to re-
start.
If the machine has been switched off for reasons of safety, then ensure
that the machine can be operated safely before re-starting.
Refer to the PRIOR TO STARTING and STARTING THE UNIT
instructions earlier in this section before re-starting the machine.
MONITORING DURING OPERATION
Should any of the safety shut-down conditions occur, the unit will stop.
Refer to the diagnostic display page for a listing of shutdown
conditions.
DECOMMISSIONING
When the machine is to be permanently decommissioned or
dismantled, it is important to ensure that all hazard risks are either
eliminated or notified to the recipient of the machine. In particular:
•
Do not destroy batteries or components containing asbestos
without containing the materials safely.
•
Do not dispose of any pressure vessel that is not clearly marked
with its relevant data plate information or rendered unusable by
drilling, cutting etc.
•
Do not allow lubricants or coolants to be released into land surfaces
or drains.
•
Do not dispose of a complete machine without documentation
relating to instructions for its use.
NOTE: Position (2) not used on this model. Pre-heaters or glow
plugs are not fitted on this model.
NOTE: Wear hearing protection at all times when the engine is
started with the manual blowdown valve open and air is flowing
from the valve.
NOTE: In order to allow the machine to start at a reduced load, a
valve, which is operated by a button located on the instrument
panel, is incorporated in the regulation system. (The valve
automatically returns to the start position when the machine is
switched off and air pressure relieved from the system).
NOTE: As soon as the engine stops, the automatic blowdown
valve will relieve all pressure from the system.
CAUTION: Never allow the machine to stand idle with pressure
in the system.
CAUTION: To ensure an adequate flow of oil to the compressor
at low temperature, never allow the discharge pressure to fall
below 3,5 bar (50 psi).
