MAINTENANCE

7/73 - 10/53

 

Alternator/drive belt failure circuit.

At twelve month intervals test the alternator drive belt failure circuit as
follows:

Remove the drive belt from the machine.

Turn  the  key  switch  to  position  1,  the  alternator  charge  light  will
illuminate.

Turn the key switch to position 3 (engine start position).

The machine will start and alternator charge light / battery light will
illuminate.

Low engine fuel level switch.

At three month intervals, test the low engine fuel level switch circuit as
follows:

Start the machine.

Disconnect the switch, the machine should shutdown.

Re-connect the switch.

At  twelve  month  intervals,  test  the  low  engine  fuel  level  switch  by
removing and operating the float manually.

SCAVENGE LINE

The  scavenge  line  runs  from  the  spin-on  filter  housing  to  the  orifice
fitting located in the airend.

Examine the orifice, check valve and hoses at every service or in the
event of oil carryover into the discharge air.

It  is  good  preventative  maintenance  to  check  that  the  scavenge  line
and  tube  are  clear  of  any  obstruction  each  time  the  compressor
lubricant is changed as any blockage will result in oil carryover into the
discharge air.

COMPRESSOR OIL FILTER

Refer  to  the 

MAINTENANCE  CHART

  in  this  section  for  the

recommended servicing intervals.

Removal

Clean the exterior of the filter housing and remove the spin-on element
by turning it in a counter-clockwise direction.

Inspection

Examine the filter element.

Reassembly

Clean  the  filter  gasket  contact  area  and  install  the  new  element  by
screwing in a clockwise direction until the gasket makes contact with
the filter housing. Tighten a further

 of a revolution.

COMPRESSOR SPIN-ON OIL SEPARATOR FILTER ELEMENT

See Maintenance Schedule.

Removal

Remove the spin-on separator element by turning the element counter-
clockwise.

Reassembly

Check the spin-on filter base for contamination and clean as required.

Replace  the  compressor  oil  (refer  to 

LUBRICATION

  later  in  this

section).

COMPRESSOR OIL COOLER AND ENGINE RADIATOR

When grease, oil and dirt accumulate on the exterior surfaces of the oil
cooler and radiator, the efficiency is impaired. It is recommended that
each month the oil cooler and radiator be cleaned by directing a jet of
compressed  air,  (carrying  if  possible  a  non-flammable  cleaning
solvent)  over  the  exterior  core  of  the  cooler/radiator.  This  should
remove any accumulation of oil, grease and dirt from the exterior core
of the cooler so that the entire cooling area can radiate the heat of the
lubricating and cooling oil/water into the air stream.

AIR FILTER ELEMENTS

The  air  filter  should  be  inspected  regularly  (refer  to  the 

SERVICE/

MAINTENANCE  CHART

)  and  the  element  replaced  every  1  Year

(1000 hours). The dust collector box(es) should be cleaned daily (more
frequently  in  dusty  operating  conditions)  and  not  allowed  to  become
more than half full.

Removal

NOTE: 

Do not press the load button.

CAUTION:

 Never remove or replace switches when the machine is

running.

WARNING: Do not remove the filter(s) without first making sure
that  the  machine  is  stopped  and  the  system  has  been
completely relieved of all air pressure. (Refer to 

STOPPING THE

UNIT

  in  the 

OPERATING  INSTRUCTIONS

  section  of  this

manual).

CAUTION: 

If  there  is  any  indication  of  the  formation  of  varnishes,

shellacs  or  lacquers  on  the  filter  element,  it  is  a  warning  that  the
compressor  lubricating  and  cooling  oil  has  deteriorated  and  that  it
should be changed immediately. Refer to LUBRICATION later in this
section.

CAUTION: 

Start  the  machine  (refer  to  PRIOR  TO  STARTING  and

STARTING THE UNIT in the OPERATING INSTRUCTIONS section
of this manual) and check for leakage before the machine is put back
into service.

WARNING: Do not remove the filter(s) without first making sure
that  the  machine  is  stopped  and  the  system  has  been
completely relieved of all air pressure. (Refer to 

STOPPING THE

UNIT

  in  the 

OPERATING  INSTRUCTIONS

  section  of  this

manual).

CAUTION: 

Start  the  machine  (refer  to  PRIOR  TO  STARTING  and

STARTING THE UNIT in the OPERATING INSTRUCTIONS section
of this manual) and check for leakage before the machine is put back
into service.

WARNING:  Hot  engine  coolant  and  steam  can  cause  injury.
When  adding  coolant  or  antifreeze  solution  to  the  engine
radiator, stop the engine at least one minute prior to releasing
the radiator filler cap. Using a cloth to protect the hand, slowly
release the filler cap, absorbing any released fluid with the cloth.
Do not remove the filler cap until all excess fluid is released and
the engine cooling system fully depressurised.

WARNING:  Follow  the  instructions  provided  by  the  antifreeze
supplier  when  adding  or  draining  the  antifreeze  solution.  It  is
advisable to wear personal protective equipment to prevent skin
and eye contact with the antifreeze solution.

CAUTION: 

Never remove and replace element(s) when the machine

is running.
