Burr King Model 960-272 - Manual (Page 10)

Functional machine operating instructions
Perform the following steps before each use of your model 960-272 belt grinder:
1. Insure that the gap (nip point) between the face of the abrasive belt and the work rest is adjusted so
that your work piece will not pass through this gap. See Figure 2.1
2. Locate the two 9/16 inch hex nuts and studs that secure the motor adapter (P/N 908) to the electric
motor. The machine can be adjusted to positions between vertical to horizontal by loosening these
nuts, pivoting the machine and securing the nuts. See Figure 2.2
3. Check the nut that secures the contact wheel (P/N 902 or 1002) to its mount. Insure this nut is
tightened to 10 to 15 foot pounds of torque. (1.4 - 2 kg force metres) See Figure 2.3
4. Insure that the abrasive belt is tensioned properly. To do this raise the tensioning handle (P/N
937G). You will hear mechanical clicks as the tensioning ratchet pawl (737F) moves. Generally,
the belt will be adequately tensioned when you hear three to eight clicks. To reduce or release the
belt tension slightly raise the tensioning handle (P/N 737A) then press the button (P/N 737B) in the
center of the tensioning handle. Move the tensioning handle down slightly to reduce belt tension or
all the way down to release belt tension. See Figure 2.4
5. Insure that your hands and other body parts and electrical cords are completely clear of the grinding
belt, and pinch points.
6. Protect your face and eyes and other body tissue from grinding debris.
