6. Mounting the wheel guard
Be sure to mount the wheel guard at an angle that will protect the operator's body from
injury by a broken wheel piece.
[Installing and adjusting the wheel guard]
Open the lever and insert the locating pin
of wheel guard, bringing it into line with
the across flats of packing ground.
Then, turn the wheel guard to a desired
position (for use).
Close the lever and fix it. If and when
required, carry out adjustments by
tightening or loosening the screw.
If the lever does not move smoothly, apply
some lubricating oil to the sliding section
between the set piece and the lever.
Fasten the wheel guard at the position
where the across flats of the wheel guard
positioning pin and packing ground are
aligned (the position where the wheel
guard is inserted), but do not use it.
WARNING:
If the wheel guard is not
attached properly, a broken
wheel may result in and
cause death or serious
injury.
7. Thoroughly check that the depressed center wheel is free of cracks, splits and
other abnomalities before mounting. Make sure it is firmly clamped and has
been properly mounted. Refer to page 14 of this manual for Depressed Center
Wheel Assembly and Disassembly.
8. Test the grinder before using
Before actually beginning the grinding work, test the grinder by first clearing the area
of all other personnel. Make sure the wheel guard is in place and that you are wearing
eye protection. Turn the grinder "on", and make sure the grinder runs smoothly and
shows no abnormalities.
Duration of the trial run is as follows:
When depressed center wheel is replaced .................. 3 minutes or more
When starting daily work .............................................. 1 minute or more
9. Use only properly rated depressed center wheels
Use only depressed center wheels rated at 6600 RPM or more.
Using a depressed center wheel rated less can lead to wheel disintegration during
operation and cause serious bodily injury.
10. Check the push button
Make sure that the push button is disengaged by pushing push button two or three
times before turning on the grinder. (Fig. 5)
