MAINTENANCE
SPRAY APPLICATOR
● Keep the internal workings of the spray applicator clean. The spray applicator should be thoroughly cleaned
after each use. Follow the cleaning instructions on page 6 with reference to the drawings on page 8
● Check the needle and fluid tip on a regular basis for excessive wear, and replace as necessary. See the
cleaning instructions for the correct procedure for removing these parts. Replacement needle sets are
available from Earlex Inc.
● Keep all moving parts lubricated with a light smear of ‘silicone free’ grease.
● Lubricate the gland washer, after each time you clean it, with a light smear of ‘silicone free’ grease.
● Check there is no leakage from the gland washer. If there is, tighten the gland nut a little to ensure a seal
with the needle. Do not over-tighten this nut, also ensure the gland washer has not dried out. If it has,
lubricate it as above.
TURBINE UNIT
● Check the condition of the cartridge filter that is housed in the front cover. This is easily removed by sliding
it upwards. If it is clogged, remove it and blow out using an airline or washed out using a mild detergent if
necessary.
● Keep the outer surface of the air hose free from harmful substances such as petrol, cellulose thinners, paint
strippers & oil. Prolonged exposure to such substances may cause irreparable damage. Always check and
clean off any excess immediately.
● Check the condition of the power cord regularly. If there are any cuts or serious abrasions to the outer
sheath, replace it immediately. When the unit is not in use, keep the power cord coiled around the brackets
at the back of the turbine case. When the unit is being used, protect the power cord and any extension cord
from damage that could be caused, for example, by traffic or hazardous substances.
The turbine unit can only be fully serviced by authorised service agents.
