emission requirements.
Category
CARB
The Emission Compliance Period used
on the CARB-Air Index Label indicates
the terms:
Engine
STIHL single cylinder two-stroke engine
Ignition system
Electronic magneto ignition
Fuel system
All position diaphragm carburetor with
integral fuel pump
Air filter
Main filter (paper filter) and flocked wire
mesh auxiliary filter
Weight
Abrasive cutting wheels
The quoted maximum permissible
operating speed of the abrasive cutting
wheel must be greater than or equal to
the maximum spindle speed of the cut-
off machine used.
STIHL has developed a composite
cutting wheel suitable for dry cutting
metals with the TS 440. STIHL has not
developed a composite cutting wheel for
cutting other materials with the TS 440,
or for wet cutting. Composite cutting
wheels rated for traditional, high-speed
cut-off machines should not be used
with the TS 440, which has a maximum
spindle speed of 2750 rpm. The TS 440
should not be used for wet cutting when
equipped with a composite cutting
wheel, as wet cutting increases the risk
of wheel failure and severe or fatal
personal injury and property damage.
