Operation
PERFORM THE FOLLOWING STEPS
BEFORE EACH USE OF YOUR
MODEL X400 BELT GRINDER:
1. Ensure that the gap (nip point) between the face of
the abrasive belt and work rest is adjusted so that your
work piece will not pass through this gap. (Figure 1)
2. Locate the 5/16" Allen screw that secures the table
support arm to the frame and loosen it. (Figure 2)
3. Adjust the mower blade table rest by loosening the
Attachment Locking Lever (Item 11, page 5) and
raise or lower the table to reduce the gap between
the belt and the table so the belt is NOT in contact
with the table. Tighten lever to secure table in place.
ADJUSTING VERTICAL/
HORIZONTAL POSITION
4. Next, loosen the contact wheel guard bolt with a 3/16"
Allen wrench. The machine can then be adjusted to
positions between vertical to horizontal, (Figure 5)
pivoting the machine and tightening. Take precautions
to not over tightening the Allen screws. As a rule of
thumb, a 1/4 turn past snug will suffice. (Figure 2)
5. Check the nut that secures the contact wheel to its
mount. Ensure this nut is tightened to 10 to 15 foot
pounds of torque. (1.4 – 2 kg meters) (Figure 3)
6. To install or remove abrasive belt, push the Tension
Handle toward the rear of the machine. (Figure 4)
When the spring tension is released, open the door
of the guard and install or remove the abrasive
belt. Return the tension handle to its position at
the front of the machine to tighten the belt.
7. Hand turn the contact wheel in the direction of the
belt travel to align the belt. Close guard door. See the
tracking section (next) to learn how to track the belt.
8. When selecting where to grind on your machine,
remember that the X400 has three designated
grinding areas. The contact wheel, slack belt area,
and the platen area. You may wish to create a
larger slack belt area by removing the backup
platen. Remove the two Allen screws that secure
the platen to the contact wheel guard. Rotate the
guard forward to cover the pinch point between.
9. Ensure that your hands and other body parts
and electrical cords are completely clear of
the grinding belt, and pinch points.
10. Protect your face, eyes, and other body
tissue from the grinding debris.
WARNING:
FAILURE TO PROPERLY ADJUST THE NIP POINT
MAY CAUSE YOUR PART TO BECOME LODGED
OR EJECTED, AND MAY LEAD TO BODILY HARM.
WEAR PROPER CLOTHING AND PERSONAL PROTECTION
EQUIPMENT WHEN OPERATING.
