Operating Instructions
WARNING
The wheel guard on the TS 440 is
adjustable. It is extremely important that
the wheel guard is in place and adjusted
properly for the type of work you are
doing, your stance and your work
position. The guard should always be
adjusted so that the user is not
endangered by particles of the material
being cut, sparks or pieces of damaged
wheels, either directly or by ricochet.
Failure to follow this instruction could
result in serious or fatal injury.
Particular care must be taken when the
guard is adjusted to expose the top of
the wheel. The guard should only be
adjusted to this position when necessary
to access the underside of a pipe or
other structure, or to finish cuts requiring
use of the top portion of the wheel.
When cutting the underside of a pipe or
other structure, the pipe or other
structure itself should provide protection
against debris, but if the operator is
endangered by debris, the guard must
be adjusted to protect the operator. That
may mean, in some circumstances, the
TS 440 cannot be used to complete a
cut. The guard always should be
adjusted forward to cover the top of the
wheel immediately upon completion of
TS 440
any cut requiring the top of the wheel to
be exposed. STIHL recommends
always guarding as much of the top of
the wheel as possible and not opening
the guard any further than necessary to
make or complete a cut.
The recommended guard position for
use of the TS 440, whenever possible, is
fully forward to the forward stop position,
which will then cover the top of the
abrasive cutting wheel down to the point
roughly midway between 9:00 and 12:00
(when viewing the wheel from the fan
wheel housing side of the machine). See
illustration, above.
WARNING
To reduce the risk of severe injury or
death, always shut off the machine and
allow the wheel to stop before
attempting to adjust the guard. After
shutting off the machine, the wheel will
continue to rotate for a few seconds
before the brake engages. Never
attempt to adjust the guard while the
engine is running or the wheel is still
rotating.
WARNING
Always check the wheel before use and
after unintentionally striking any object;
check it frequently during use when the
engine is turned off. Look for cracks and
other damage, such as cracked, missing
or broken segments on a diamond
cutting wheel. Make sure that the wheel
is undamaged and in good condition,
that it is not cracked, that no pieces have
broken off and that no segments are
loose, missing or damaged. See the
sections "Abrasive Cutting Wheels" and
"Reactive Forces" in this manual. Check
the wheel guard for cracks or other
damage. If you discover any breaks,
cracks or other damage, mount a new
guard before further use.
WARNING
It is essential to determine the exact
direction of the cut before applying the
abrasive cutting wheel to the workpiece.
Wheels are constructed for radial
pressure only. To reduce the risk of
wheel breakage and severe personal
injury or death, avoid putting lateral
pressure (side loading) on the wheel.
Hold the cut-off machine steady. Work
along a straight cutting line. To reduce
the risk of serious or fatal injury, do not
attempt to correct the position or
direction of a cut by tilting or twisting the
machine or cutting wheel, as this may
produce a high torsional load on the
abrasive cutting wheel and may cause it
to bind, break or shatter. If corrections
are necessary, always lift the machine
and reposition the cutting wheel, taking
care to ensure that it is not wedged,
tilted, twisted or side loaded. Attempting
to change the position or direction of a
cut while the wheel is in the cut can bind
the wheel. This can lead to kickback,
other reactive forces or a shattered
composite cutting wheel, which could
result in severe or fatal personal injury.
See the section "Reactive Forces" in this
manual.
WARNING
Use your cut-off machine for cutting
only. It is not designed for prying,
shoveling or moving any objects.
