MAINTENANCE
The mains plug always needs to be taken out of the
socket (the mains socket) during maintenance,
inspection or cleaning activities.
PERIODIC MAINTENANCE OF THE COMPRES-
SOR WILL PREVENT UNNECESSARY PROBLEMS!
FAULTS
Should a fault occur, e.g. after wear of a part, please con-
tact your local Ferm dealer.
In the back of this manual you find an exploded view
showing the parts that can be ordered.
POSSIBLE PROBLEMS AND REMEDIES
Fig. F
Air leaks through the pressure switch (1) when
the compressor is stopped
• Non return valve worn or dirty not working properly
• Dismantle the non return valve head clean rubber
disc (R) and/or replace it
• Reassemble with care.
Reduction in performance, starting too often or
low pressure
If the demand on the air supply remains the same, check
for air leaks on pipe and hoses, the conditions of the
intake filter or belt-driven regulation.
• Replace the seals of the fittings-clean or change air
intake cartridge.
• Recheck the regulation of belts
The motor or the pump overheats
Not enough cooling air on the motor or the pump.
• Check ambient temperature, oil level and quality,
intake filter, proper voltage.
The compressor stops after trying to start or
stops and will not start again
• The air tank is full. Improper voltage or lubrication
• Bad connection
• Check all parameter as before.
• If the problem is not resolved contact the specialist
service organisation
Anomal presence of oil in the compressed air.
• Excessive oil level.
• Wear of piston rings
• Check oil level
• Ask for Assistance
CONDENSATION
Humidity of the air wich condenses in the tank must be
drained, at least weekly through tap (6). If there is no oil
in the condensed water than it may be drained without
fear and pollution.
DRIVE BELTS TENSION
Drive belts require a precise tensioning of the belt
because at low values there are slippings on the pulley
causing overheating, and rapid wear of the belt. High
values cause excessive load on the bearing causing fast
wear of the same and motor over heating. The correct
tension value is obtained pushing with a screwdriver on
the intermediate area and you obtain a deflection of 1 cm.
OILLEVEL
The compressor comes with a special test oil, that must
be Replaced after about 100 hours of use. Check the oil
level from time to time, using the oil gauge.
When the compressor is level and has not been used for
some time, the oil level should be within the area indica-
ted by both marks on the gauge. The oil must be replaced
after every 300 hours of use or at least once a year. Use
compressor oil API CC SAE 40 rather than motor oil. If
the compressor is used in temperatures below 0°C, use
API CC SAE 20 oil.
EVERY MONTH
Clean the air filter
Every 300 working hours:
• Refresh the oil
• Carefully clean the outside of both the compressor
and the engine, to ensure an efficient cooling.
Condensation
• Regularly, drain condensation from the air chamber,
using the drain cock situated on the underneath of
the air chamber.
