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
