Cutting wheel

Do not grind on the side of an abrasive engine cut-off saw wheel, or put any side pressure on the wheel during cut-
ting. Avoid letting the saw tilt or wobble off line.
Use new, properly qualified wheels of correct diameter, thickness and mounting hole size. The wheel blotters and
the mounting flanges should be in good condition, and the mounting bolt should be tightened to the proper torque.
Select and use the appropriate wheel for your work.
Inspect the wheel carefully for cracks, edge damage and warping before use. Do not use any wheel that has been
dropped. A wheel once dropped cannot be trusted.
Do not mount wheel if blotters are damaged. Do not destroy cushioning effect by making mounting bolts too tight.
Never fasten while applying your weight. Otherwise the thread could be broken. Proper torque is 25 N•m (250 kgf•cm)
- 30 N•m (300 kgf•cm).
Examine wheel carefully before use. Do not use if wheel is warped, damp, cracked, chipped or cutting area shows
heat discolouration.
Use the only wheel that conforms to national and local laws and regulations such as EN13236, EN12413 and ANSI
B7.1.
Comply with safe handling instructed by wheel manufacturers.
Do not use water while cutting with a abrasive wheel unless the wheel manufacturer specifies.

Wheel Speed Rating
This is the minimum acceptable wheel speed rating for this
unit. Wheels rated less than 3820 r/min must not be used on
this engine cut-off saw.
Maximum Allowable Wheel Speed
The wheel rotates at the same speed as the spindle (arbour)
on which it is mounted. The wheel must never be allowed to
rotate faster than 3820 r/min if the wheel speed is rated at
3820 r/min.
Wheel blotters attached to both sides of reinforced wheels are
cushions needed to equalize the pressure of the mounting
flanges from wear if slippage between the wheel and the flang-
es occurs. The blotters are 108 mm diameter. Take care that
the blotters do not become gouged or deeply scratched and
that there is no foreign material on them when mounting the
wheel.
1. The wheels are made by laying a strong fibre mesh material
into a form, pouring a mixture of resin and the abrasive grit
particles over the mesh, and adding a second layer of mesh
over the mixture. Then the resin and reinforcing mesh are
bonded together and cured.
2. The wheel's ability to cut certain materials are due to the
type abrasive, size of the grit and it's spacing. The reinforce-
ment on both sides adds strength and rigidity.
3. Always read the label on the wheel. If the wheel does not cut
well, it may be the wrong type for the material. Forcing it to
cut may result in shattering of the wheel and serious injury to
the operator.
