Extracting Clips; Adjusting The Contrast Foot For Extraction - Cembre PCMD-FC Operation And Maintenance Manual

4.9.2) Extracting clips

Make sure the locking knob (39) of the rear wheel is released (see § 4.3).
An "Extraction operation" means (see § 4.5, § 4.6, and § 4.7):
1 - Moving from "installation position" to "parking position".
2 - Moving from "installation position" to "insulator change position".
3 - In exceptional cases, the complete extraction of the clip.
Push the machine to the clips on which operations are to be performed (see § 4.3).
IMPORTANT: when performing the fi rst extraction operation, the correct stroke of the rams will have to
be established so the clips are positioned precisely (see § 5.2).
Turn the teeth (40) to the extraction position (Ref. to Fig. 14).
Mount the track spacer (41), adjusting it based on the type of rail and insulator (see § 4.9.3).
Turn the clamp control selector (15) to the extraction position "OUT".
Turn the lower ring nuts on each side to adjust the extraction stroke.
Turn the upper ring nuts used for the insertion of the clips, to prevent the tooth from scraping the rail web.
Press the clamp operation button (13) to make the teeth advance (40), bringing the clips to the "parked
position".
Once the extraction is complete, the clamps are retracted automatically (while still holding down the clamp
operation button (13)).
Lift the machine, move on to the next clips and repeat the above extraction operations (avoid lifting over the
railhead with the extraction teeth).

4.9.3) Adjusting the contrast foot for extraction

There are two operations for adjusting the track spacers (Ref. to Fig. 15):
Attach the track spacers to the machine, keeping the reference number
corresponding to the width of the rail fl ange facing the rail.
Locate its fi xing screw so the track spacer is closest to the side post insulator.
With these adjustments it is possible to operate on many track layouts.
If not suitable for the particular application required, contact Cembre.
