Do not use wrenches with longer handles,
since it may lead to over tightening of the blade
stud.
VARI-TORQUE CLUTCH
This clutching action is provided by the friction
of the OUTER WASHER against the BLADE
and permits the blade shaft to turn when the
blade encounters excessive resistance. When
the BLADE STUD is properly tightened (as
described in No. 5 of Attaching The Blade), the
blade will slip when it encounters excessive
resistance, thus reducing saw's tendency to
KICKBACK.
One setting may not be sufficient for cutting all
materials. If excessive blade slippage occurs,
tighten the blade stud a fraction of a turn more
(less than 1/8 turn). OVERTIGHTENING THE
BLADE STUD NULLIFIES THE EFFECTIVE-
NESS OF THE CLUTCH.
DUST EXTRACTION
Your tool is equipped is with a dust port for dust
and chip extraction. To use this feature, open
dust port cover and attach vacuum hose
(optional accessory) to the dust port, and
connect opposite end the hose to a shop
vacuum cleaner.
To prevent personal injury,
! WARNING
always position vacuum
hose so that it does not interfere with the
lower guard, or the cutting operation at all
settings.
