AIR FILTER ENGINE/COMPRESSOR
CLEANING THE DUST TRAP
Remove dust daily.
To remove dust from the dust trap squeeze the
vacuator valve (6) several times.
RECOMMENDATIONS
New elements must also be inspected for tears or
punctures before installation.
Discard the element (4) when damaged.
In heavy duty applications it is recommended to
install a safety cartridge, which can be ordered with
part no.: 2914 9311 00
A dirty safety cartridge (3) is an indication of a mal-
functioning air filter element. In that case replace the
element and safety cartridge.
The safety cartridge cannot be cleaned.
REPLACING THE AIR FILTER ELEMENT
1. Release the snap clips (1) and remove the dust trap
(2). Clean the trap.
2. Remove the element (4) and the safety cartridge.
3. Reassemble in reverse order of dismantling. Make
sure the vacuator valve (6) points down.
4. Inspect and tighten all air intake connections.
5. Reset the vacuum indicator by pressing the reset
button (5).
AIR RECEIVER
The air receiver (1) is tested according to official
standards. Carry out regular inspections in conformity
with local regulations.
SAFETY VALVE
Following checks must be carried out on the safety
valve (2):
•
a check of the opening of the lifting gear, twice a
year. This can be done by screwing the cap of the
valve anti-clockwise.
•
an annual check of the set pressure according to
local regulations. This check cannot be done on
the machine and must be carried out on a proper
test bench.
