2. Installing a wheel
WARNING
USING A WRONG SIZED WHEEL OR A WRONG RATED ROTATION SPEED WHEEL
CAN CAUSE WHEEL BREAKAGE AND RESULTING SERIOUS INJURY.
In order to avoid this hazard, refer to the following rated rotation speed wheel and
the following illustration to determine the proper dimensions(s) of your wheel.
Some guidelines:
(a) Use only wheels rated at 29000 /min or more. Using wheel rated less can lead to wheel
disintegration during operation and cause serious bodily injury.
(b) Dimension
ℓ
should always be less than 13 mm. Longer lengths can result in excess
vibration, wheel breakage, and the chance for serious injury.
(c) When dimension d is 6.35 mm, the
diameter of the wheel (dimension D)
should be less than 50 mm. NEVER use
a longer diameter wheel.
(d) When dimension d is 3.175 mm, the
diameter of the wheel (dimension D)
should be less than 10 mm.
(e) Dimension L varies according to the
dimension D. Dimension L can be longer
as dimension D increase. (
