Cleaning the air filter
A contaminated air filter can contribute to problems starting the machine,
loss of performance during operation and shorten engine life. Zipper
Machines does not accept any liability for engine damage caused by failure to
clean the air filter regularly.
1.
To clean the air filter, first loosen the wing nut on the air filter
housing, remove the cover (foam filter element) and remove the air
filter cartridge (paper filter element). Clean both elements
mechanically with a soft brush.
2.
If only the air filter cartridge is to be cleaned, blow it from the inside
by moving a dry jet of compressed air up and down until all the dust
has been removed.
An air filter change is pending when:
the engine power drops and fuel consumption increases at the same time
the oil consumption increases
the starting of the engine becomes more difficult

Checking and replacing V-belt and coupling
W A R N I N G
Warning of danger of detection/trapping in! Never attempt to check the V-belt
while the engine is running. Your hands could get caught between the V-belt and
the clutch. Serious hand injuries may result.
N O T I C E
If the vibratory power of the machine - regardless of the number of operating hours
- suddenly decreases or stops completely during normal operation, first of all check
the V-belt and coupling.
Loose or worn V-belts reduce power transmission efficiency, result in poor compaction
performance and shorten the service life of the belt itself. Therefore, check the V-belt tension at
the specified intervals.
17.5.1
Checking the V-belt tension
1.
Loosen the screws (S) of the V-belt cover
and remove them.
2.
Check tension
3.
The V-belt tension is OK if the belt yields
approx. 10 to 15 mm under pressure with
thumb and index finger (see illustration
on the left). If the V-belt is too loose or
too tight, adjust the tension!
4.
Reinstall the V-belt cover after a positive
check.
