Concrete Polishing Solutions- G-290 Operator’s Manual
Improperly aligned retainer and
inner polycord holder.
Note: The 3 holes of the
inner polycord holder do not
align with holes of the retainer. Flex
heads could not be mounted
to the machine in this position!
Step 3
Tighten the 8 flat head socket head screws to a snug-fit using a criss-
cross method.
It is recommended to do one full turn of the Allen wrench only before
moving to the next screw until snug.
After all screws are snug, use the criss-cross method and tighten all
screws to 6 foot pounds of torque pressure (72 inch pounds).
The screws should protrude the retainer slightly when proper torque
pressure has been reached.
***See picture below for example.
Note: The screw in the forefront is properly torqued
while the screw to the left and right are over and under tightened
respectively.
