• Move the carriage (E) to the right by turning the lead screw so that the ball bearing at the
back of the carriage gets free and the carriage later can be lifted right upwards without
any hindrance.
• Remove the code disk (B), the washer and the distance at the left end of the lead screw
by unscrewing the nut (C) on the lead screw. To do this the lead screw has to be held in-
place by inserting a socket head cap screwdriver into the screw (D) that holds the lead
screw to the motor shaft.
• Remove the two E-rings (M). Note that the right one is fixed with a screw.
• Slide the shaft (F) sidewise and remove the stopper (O) and the stroke compressor (P).
Pull the shaft out.
•
Now the carriage can be lifted straight upwards and put aside.
• Remove the lead screw (G) by first un-tighten the screw (D) that holds the lead screw to
the motor shaft and then loosen the two screws that hold the motor. Separate the motor
from the lead screw by pulling the motor to the right. The lead screw can now be remo-
ved. NOTE! The ball bearing has a given position and should not be moved unless it is
to be exchanged.
• The carriage itself should not be disassembled. The two plain bearings (K) are one-
time-only and can not be removed and inserted again.
4.1.2 Assembly
• Slide the lead screw (G) back in the ball bearing (H) and then but the motor back. Push
the lead screw (G) over the motor shaft while position the motor. Fix the motor.
• Position the lead screw sideways against the ball bearing and fix it with the socket head
cap screw (D). It is important that the ball bearing (H) is at its given position, if it has
been moved it has to be adjusted, see point 7 below.
• Put the carriage (E) back over the nut (L) on the lead screw.
• Put the shaft (F) that holds the carriage back. Make sure that thestroke compressor and
the stopper are mounted in right order.
• Put on the E-rings (M) and fix the right E-ring with the screw.
• Put the code disk (B) back. First the 5mm thick distance should be applied, then the
code disk and finally the nut. The nut must be secured with Loctite 243 or equivalent.
• The optical switch circuit board (A) is next. It should be fastened with two screws. It
need to be calibrated but a good start is if it is put close to it's original position. Most
often the position can be seen by the marks the screws make in the board. NOTE! It is
very important to verify that the sensors goes free from on one hand the ball bearing and
the other the code disk. If not, the lead screw must be adjusted. This is done by loosen
the socket head cap screw (D) and carefully press the lead screw, including the ball
bearing, sideways.
