4.2.2 Changing suction filters
The suction filter (example Figure 5) needs to be changed
only once a year, if the surrounding conditions are clean.
If the atmosphere is excessively dusty the suction filter
must be changed more often.
Dirty filters decrease the delivery output
and the lifespan of your product!
Prior to changing filters, switch product
off and pull out the mains plug!
To change the air filter, proceed as follows:
1. Turn the filter housing (1) clockwise. The bayonet lock
opens and the filter can be pulled off.
2. Exchange the air filter insert.
3. Turn the filter housing counterclockwise until the bayonet
lock is closed again.
Attention! Never clean filter inserts with
petrol or oil!
4.2.3 Check safety valve function
The safety valve (see Figure 7) is set in the factory at the
tank pressure, tested and lead sealed according to the
current regulations. Under no circumstance should
the seal be removed or the safety valve be reset. Any
tampering of the seal will invalidate all liability.
The safety valve is to be function tested semi annually.
With working pressure in the tank, turn the valve lifter (1)
counterclockwise until blown off compressed air is heard.
Turn the valve filter again in a clockwise direction until it
is closed.
