DEFINITION OF TERMS
ANSI – American National Standards Institute.
ARBOR – A spindle or axle.
ARBOR HOLE – The mounting hole in the
abrasive wheel.
AUTOMATIC BELT TENSIONER – This feature, a
spring-loaded device in the wheel arm,
maintains belt tension.
BLOTTERS – Discs of soft material placed
between wheel and mounting flanges to
equalize pressure against the wheel, and to
avoid wear on the flanges if slipping occurs.
CHAPS – Protective covers for the legs.
CHOKE CONTROL – The device used to enrich
the fuel/air mixture when starting the engine.
COLD START – Starting sequence required
whenever engine is not warm enough from
previous operation to be started without
choking.
DROP-START – An improper variation of starting
while holding saw in the air. Do not start saw in
the air.
DUST MASK – A device worn to prevent breathing
in dust.
ENGINE SPEED – The speed of the engine output
shaft.
FACE SHIELD – A device worn in front of the
eyes, and all or part of the face, to supplement
the protection afforded by a primary protective
device.
GASOHOL – Gasoline containing methyl alcohol
(methanol) or more than 10 % of ethyl alcohol
(ethanol) that is harmful to internal engine
parts.
GOGGLES – A device, with impact-resistant
lenses, intended to protect the eyes from the
front, top and sides. The goggles are stamped
Z 87 for qualification.
GOVERNOR – A device which limits the speed of
the engine.
IDLE SPEED – An engine speed which is slow
enough that the clutch does not engage.
IGNITION SWITCH – The device which allows the
operator to run or stop the engine.
KICKBACK – A dangerous reaction and
movement off the saw, in an upward arc
towards the operator, caused by contact with
an object at the front segment of the wheel.
NO LOAD SPEED – The speed of the engine
when no load is applied.
REDUCTION RATIO – The ratio between the
engine speed and the spindle speed.
REINFORCED WHEEL – Abrasive wheels bonded
on both sides with layers of a fiber mesh
material.
SPINDLE – An axle or arbor.
SPINDLE SPEED – The speed at which the
spindle or wheel axle rotates.
THROTTLE LATCH – A device used to latch the
throttle trigger in a position for starting the
engine.
THROTTLE TRIGGER LOCKOUT LEVER – A
lever on the rear handle grip which the operator
must hold depressed for control of the throttle
trigger, and when released will lock the throttle
control in the idle position.
THROTTLE TRIGGER – The device in the rear
handle used to control the speed of the engine.
TWO-STROKE FUEL – Fuel containing the
lubricant for two-stroke engines. It is made by
mixing 2-stroke engine oil with gasoline.
WATER-FLUSH – Constantly spraying the stone
or masonry surface during cutting, in order to
reduce exposure to dust, and also cool the
wheel.
WHEEL GUARD – A wheel shield which is
intended to protect the operator from wheel
contact, and also direct debris away from the
operator.
WHEEL SPEED – The speed (r/min) of the shaft
(spindle, arbor) on which the cutting wheel is
mounted.
WHEEL SPEED RATING – The speed printed on
the label of the wheel by the manufacturer is
the maximum allowable wheel speed.
WHEEL THRUST – The force of the wheel against
the work, felt by the operator as a pull of the
saw.
