Snugger Clamp Setting (Height)
The procedure for setting up the snugger height is as follows:
1. Before setting snugger height, check the rail to table height (Rising Table
Chapter of the Technical Reference Manual refers).
2. Place a straight edge on the top surface of the rear rail guide (Position A1
on figure below refers). Using a depth gauge indicator measure the distance
from the top of the rising table to the top of the rear rail guide.
3. Carry out same operation at Position A2.
4. Check that the dimensions in Steps 2 and 3 are the same (to within 0.2mm).
If necessary adjust by slackening snugger support bracket securing screws.
Do not fully re-tighten screws at this point.
5. Carry out identical checks at other end of adjustable snugger plate (Position
B1 and B2). On completion of check/adjustments fully re-tighten bracket
securing screws.
NOTE
If adjustments are made ensure that a gap of 250mm is maintained as laid
out in Parallelism setting up.
6. On completion of setting up ensure that the board is free to move along the
transport rail without jamming.
7. Pneumatically operate the snugger clamp with a board fitted. Ensure that
the board is gripped evenly along its entire length.

Home Position Rail Width Check
1. In Diagnostics, select Rail System and Select Module.
2. Select Home Rail Width and Run Diagnost.
3. Select Adjust and set board width to 250mm.
4. Select Drive Rail to Board Width.
5. Select Run Diagnost.
6. Check that the board clamp width is between 250.35mm - 250.55mm.
NOTE
If the rail width is out of tolerance do not adjust the rails, adjust the position of
the rail home position sensor and recheck.
7. Using a suitable test board, with the rail width programmed to the board size,
adjust the downline and upline auxiliary rails to the same width.
8. Select Cycle Board on Belts.
9. Select Run and ensure the board runs through the entire length of the rail
system for 10 complete cycles, without jamming or excessive clicking of the
board edges.
NOTE
If any jamming occurs investigate the position of the board/snugger clamps at
the rail ends before repeating the check.

Rail Shock Absorber Setting
1. Ensure the machine is powered down.
2. Using feeler gauges, check that a gap of 2.5mm - 3.0mm exists between
the top of the plunger and the shock absorber body. Alternatively use a
2.5mm and 3.0mm Allen key as a Go, No Go Gauge.
3. Repeat Step 2 for the three other rail shock absorbers.
4. If adjustment is necessary, slacken the lock nut.
5. Rotate the shock absorber body as required, clockwise to reduce the gap,
anti-clockwise to increase the gap.
6. Check the gap is between 2.5mm - 3.0mm.
7. Repeat Steps 5 and 6 until the correct dimension is achieved
8. Tighten the lock nut.
9. Recheck the gap is still within limits.
Reversing Throughput Direction
To change the direction of throughput of the machine, carry out one of the
following two procedures:
Right to Left
Configuration
To change the configuration of the machine from Left to Right to Right to Left
throughput carry out the following:
1. If required, raise the head and insert the head prop.
2. Power down the machine and disconnect the quick release pneumatic
connection at the machine’s external services panel
3. Gain access to the left hand auxiliary conveyor sensor.
4. Remove the two sensor securing screws and remove the sensor from the
mounting bracket.
