GENERAL OPERATION
Operating a Square 1 Design Roof Truss Finish Roller is a relatively simple job. The Square 1 Design Roof
Truss Finish Rollers are designed to be continuous running machines. There are several adjustments that
will be a part of daily operation. This section lists these adjustments as well as instructs the user on how
to perform them. One thing that must ALWAYS be remembered is to:
DRIVE CHAIN ADJUSTMENT
All models of the Square 1 Design Roof Truss Finish Rollers have a drive train on both ends. All rollers are
pre-set at Square 1 Design for a standard 2 x 4, and chain tension is pre-set. You may want to feel the
tension in the chain when it arrives, so you know the correct tension of the chain.
RIGHT DRIVE TRAIN ADJUSTMENT
•Adjustment is begun by removing the nut and lock washer holding the right end chain guard
closed. Prop open the chain guard to allow enough space to work free of any obstructions.
Loosen the locknut holding the idler sprocket adjustment screw in place.
•The idler sprocket may then be adjusted by turning the bolt clockwise to increase tension. Turn
the bolt counter clockwise to decrease tension. A little slack is desirable as it allows the chain
links seat themselves on the sprocket teeth. This will reduce wear on the on the sprocket and
bearings.
•After adjustment is complete, the locknut must be tightened to maintain proper tension. Close
the chain guard and replace the lock washer and nut.
LEFT DRIVE TRAIN ADJUSTMENT
•Adjustment is begun by removing the nut and lock washer holding the left end chain guard
closed. Prop open the chain guard to allow enough space to work free of any obstructions.
•Loosen the 4 mounting bolts holding the left gear reducer to the base. Chain tension is increased
by turning the adjustment bolts clockwise and reduced by turning the adjustment bolts
counterclockwise. A little slack is desirable as it will allow the chain links to seat themselves. You
must be sure the drive sprocket is still in line with the roll sprocket.
•After adjustment is complete the 4 mounting bolts must be tightened to maintain proper
tension. Close the chain guard and replace the lock washer and nut.

ALWAYS DISCONNECT AND LOCK OUT ANY POWER SOURCES WHEN ADUSTING OR REPAIRING ANY EQUIPMENT.
10
ROLLER ADJUSTMENT
The Square 1 Design Roof Truss Finish Rollers have up to 4 1/2” of total roller adjustment. The top roller
is the only adjustable roller. The bottom roller remains stationary and is set at 32” high from the floor,
unless ordered otherwise.
•To adjust the top roller height both end guards must be opened. The drive chain idler sprocket
adjustment must be loosened to allow plenty of slack in the drive chain. Care must be taken
during upper roller adjustment to assure there is enough slack in the chain to allow full roller
adjustment. Depending on the amount of movement, you may want to move each end up a
little at a time. The bearings are self-aligning, but to avoid going too far, it is best to move each
end a little at a time.
•To lower the top roller, loosen the bottom roller adjustment nuts on both ends of the roller
assembly. Begin by turning the top roller adjustment nuts counter clockwise to lower each end
of the roll. When the roll is at the correct height, tighten the adjustment nuts to lock the roll in
place.
•To raise the top roller, loosen the bottom roller adjustment nuts on both ends of the roller
assembly. Begin by turning the top roller adjustment nuts clockwise to raise each end of the roll.
When the roll is at the correct height, tighten the adjustment nuts to lock the roll in place.
•Readjust the chain drive to the proper tension, close the guards, unlock the machine and test
run the Square 1 Design Finish Roller.
Note: When adjusting the roller height, raise the roll so that a piece of the lumber you are going to use
can be inserted between the rolls. Insert two pieces of the lumber in at each end of the roll. Now, lower
the roll onto the lumber. When the lumber can be wiggled from side to side, but cannot be pulled out,
the roll is at the correct height.
