z Checking the air cleaner cartridge
- Before reinstalling the cartridge, it
must be checked for damage e.g. to
the paper pleats and rubber gaskets,
or for bulges and dents etc. in the
metal jacket.
- Damaged cartridges should not be
reused under any circumstances. In
cases of doubt, discard the cartridge
and install a new one.
5.5. Belt
The tension of the belts should be checked after every 2,000 hours of operation.
(1) Change the belts if necessary
If in the case of a multiple belt drive, wear or differing tensions are found, always
replace the complete set of belts.
(2) Testing by hand
z Poly belt
Poly belt will be properly tensioned
if the deflection force “F” is applied
mid-way between the belt’s
tangent points with the pulley.
(T) = 0.015 x S (about 1.5mm per
100mm).
T = 0.015 x *S (mm)
(T : Deflection, S : Span)

C : Distance of pulleys (mm)
D : Large pulley diameter (mm)
d : Small pulley diameter (mm)
