Maintenance
1. After the first 10 hours of working, empty the crank case
of oil and refill with clean oil by removing the crank case
oil plug (left hand side of the crank case at the bottom)
Note. Use good quality compressor lubricating oil.
• SAE30 or L-DAB 100 over 10°C
• SAE10 or L-DAB 68 under 10°C
2. After each subsequent 500 hours of operation, again
drain the oil and refill the crank case with clean oil.
3. After each day of operation, use the drain cock (11) under
the tank to drain off any condensate.
4. Regularly check the air filter insert cartridge inside the
air filter assembly (17) and clean or replace the insert
when necessary.
5. Check daily the operation of the safety valve. This check
should be performed when the tank contains close to
max pressure in the tank.
To check the valve, pressurise the tank, and pull the ring
OUTWARDS on the safety valve.
Air should discharge from the valve.
Release the ring of the safety valve. When the ring is
released the air discharge must stop.
WARNINGS.
Safety glasses must be worn when performing this test.
Do not have your face close to the safety valve when
performing this test as air will discharge from the valve at a
high force.
If the safety valve does not operate correctly in any way as
described above, turn off the compressor immediately and
have the compressor and safety valve checked and tested
at an authorised Service centre.
DO NOT CONTINUE TO USE THE COMPRESSOR
IN ANY WAY IF THE SAFETY VALVE DOES NOT
WORK AS ABOVE.
General inspection
1. Regularly check that all the fixing screws are tight.
2. The supply cord of the tool should be checked frequently
for damage. If damaged, have the cordset replaced by an
authorised service facility to avoid
a hazard.
Cleaning
1. Keep the tool’s air vents unclogged and clean at
all times.
2. Remove dust and dirt regularly. Cleaning is best done
with a soft brush or a rag.
3. Re-lubricate all moving parts at regular intervals.
4. If the body of the compressor needs cleaning, wipe it
with a soft damp cloth. A mild detergent can be used but
nothing like alcohol, petrol or other cleaning agent.
5. Never use caustic agents to clean plastic parts.
CAUTION. Water must never come into contact
with the tool.
Power cord maintenance
Only an authorised service centre should replace the
cordset or carry out other repairs. If the cordset is damaged
or worn, have it repaired or replaced by an authorised
service centre.
