. Just because the acces-
sory can be attached to this power tool, it does
not assure safe operation. The rated speed of the
accessory must be at least equal to the maximum
speed marked on this power tool. Accessories run-
ning faster than their rated speed can break and
fly apart. The outside diameter and the thickness
of your accessory must be within the capacity rat-
ing of this power tool. Incorrectly sized accesso-
ries cannot be adequately guarded or controlled.
Threaded mounting of accessories must match
the spindle thread. For accessories mounted by
flanges, the arbour hole of the accessory must fit
the locating diameter of the flange. Accessories
that do not match the mounting hardware of this
power tool will run out of balance, vibrate exces-
sively and may cause loss of control. Do not use
a damaged accessory. Before each use, inspect
the accessory. If this power tool or its accessory is
dropped, inspect for damage or install an undam-
aged accessory. After inspecting and installing an
accessory, position yourself and bystanders away
from the plane of the rotating accessory and run
this power tool at maximum no-load speed for one
minute. Damaged accessories will normally break
apart during this test time. Position the cord clear
of the spinning accessory. If you lose control, the
cord may be cut or snagged and your hand or arm
may be pulled into the spinning accessory. Reg-
ularly clean this power tool’s air vents. The mo-
tor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may
cause electrical hazards.
