Multiquip SFG10E manual Maintenance/Service, Installing a Replacement V-BELT or Pulley

FIGURE 41

5)Belt alignment is checked with the straightedge. Place the straightedge squarely against the transmission pulley. Properly aligned pulleys should also place the straightedge squarely against the motor pulley. Remove the straightedge and rotate the motor pulley 120 degrees. FIGURE 42. Recheck alignment with the straightedge. Repeat the process until the motor pulley is rotated a full 360 degrees. Maximum allowable misalignment is + - 1/32 inch. If pulley alignment is not within specifications, refer to INSTALLING A REPLACEMENT V-BELT for specific information.

6)Install the belt guard to the main frame. Determine that all safety related decals affixed to the belt guard are fully readable. If any decal is not fully readable, replace with a factory approved, replacement part only.

7)If the machine is to be used immediately, reconnect the extension cord or SURFACE GRINDER to the power source. Determine that the ON/OFF switch located on the operator handle is in the OFF position
