SAFETY INSTRUCTIONS
NOTICE
The manufacturer accepts no responsibility for damage resulting from non-
compliance with the documentation.
•LNS accepts no responsibility for accidents or material damage resulting from failure to observe the safety instructions.
•Never handle the equipment without taking into account the safety instructions and instructions for use. Safety
instructions for the bar feeder, as well as the CNC lathe, must be strictly observed.
•The equipment must not be used or handled by unskilled personnel, children or persons under the influence of alcohol or
medication.
•It is recommended not to wear jewelry and loose clothing, and to tie long hair.
•Always uncouple the bar feeder from the machine before removing the covers.
•It is strictly forbidden to remove safety equipment. If necessary, to ensure the smooth running of an adjustment or
maintenance procedure, it must be reinstalled immediately afterwards.
•Never walk on the belt.
•Never put your hands into the moving bar feeder.
•No servicing should be carried out on the interface or inside the electrical cabinet while the bar feeder or the lathe is
powered on.
•It is strictly forbidden to bridge or remove circuit breakers and main switches, especially safety switches.
•To ensure the safety of components and personnel, observe the points indicated for lifting and moving the bar feeder. It
is expressly forbidden to stay near the suspended load or in the operating area of the crane, the forklift truck or any other
lifting and transport equipment.
•Be careful not to hit the bar feeder when it is moving, as this may damage it.
•Never move the bar feeder while it is powered on.
•Always switch off the bar feeder prior to service, maintenance or repair.
•The work area around the bar feeder must be well lit and clear. It is important to clean the floor on a regular basis, as the
presence of oil can result in falls.
•Do not place the machine in a damp area, and make sure that the water or oil never comes into contact with the
electrical equipment.
•Never try to recharge the batteries of the PLC.
•Always use the parts supplied or recommended by LNS for use/intervention on the bar feeder for maintenance purposes.
•If it is necessary to move the bar feeder after commissioning, always contact LNS or a local representative before
restarting the system.

PROCEDURES
SERVICE MANUAL – QL Servo S3-T
2. PROCEDURES
SETUP, ALIGNMENT, AND ANCHOR PROCEDURE
INFORMATION
The following conditions must be met to complete this procedure:
•Bar feeder power off
•No pneumatic pressure
Reminders:
•To obtain a perfect alignment, it is advisable to install the largest feeding pusher.
•If a spindle liner is installed, make sure that its I.D. is larger than the O.D. of the feeding pusher.
•It is not mandatory that the lateral level of the bar feed system is perfect; just make sure that the latter is as straight as
possible.
•The longitudinal level of the bar feed system must be adjusted according to the level of the lathe, even if the lathe lies
only over three points and cannot be perfectly levelled.
Should the level of the bar feed system not correspond to that of the lathe, the feeding pusher might touch the inside
of the spindle.
Place the bar feeder as close as possible behind the headstock lathe. The distance between the front of bar feeder and the
back of headstock lathe should be as small as possible.
Before proceeding with the alignment of the bar feed system, ensure that the lathe is stable and levelled.
1. Position the bar feed as close as possible to the rear of the lathe. The distance between the front
of the bar feed and the back of the spindle should be as small as possible.
Note :
If obstacles prevent the bar feed from being positioned within 8 inches of the back of the spindle an
extension will be required.

PROCEDURES
SERVICE MANUAL – QL Servo S3-T
2. Level the bar feed in the x and y axis using a torpedo level. The level can be placed on the linear
belt rail to verify the y-axis and on the retract rails to verify the x-axis. Use the leveling screws
(shown with arrows) on the retract to adjust unit to level.
3. Carefully loosen the 16 screws located in the slots on the base of the unit. This will allow the unit
to be adjusted up and down.

PROCEDURES
SERVICE MANUAL – QL Servo S3-T
4. Using the central jackscrew (1) and the hexagonal tube (2) supplied with the bar feed; adjust the
unit so that the pusher is centered up and down at the back of the spindle. Make sure that the unit
raises or lowers uniformly.
5. Once the pusher is centered up and down, tighten the 16 screws to secure unit and recheck the
level of the unit.

PROCEDURES
SERVICE MANUAL – QL Servo S3-T
6. Align the unit side to side by centering the pusher in the back of the spindle and then extending the
pusher to the back of the collet and centering it there.
Adjust the rear of the bar feed when centering to the rear of the spindle and the front of the bar feed
when centering to the rear of the collet.
Once the pusher is centered at the back of the collet recheck the alignment at the back of the spindle
by pulling the pusher back.
Continue until the pusher is centered at the rear of the spindle and the rear of the collet..
7. Once the bar feed has been aligned anchor it using the ½ inch anchor bolts supplied with the unit.

PROCEDURES
SERVICE MANUAL – QL Servo S3-T
8. After anchoring the unit, recheck the level and the alignment of the unit.
9. After the alignment has been rechecked, power and air will need to be hooked up to the bar
feeder.
10. Once the power and air have been hooked up, the bar feed must be calibrated.
After calibrating the bar feed, return to this procedure and move on to Step 11 for the final
alignment.
11. For final alignment, load a bar into the v-channel and verify that it can be loaded into the spindle of
the lathe without hitting the sides of the spindle or spindle liner.
If the bar hits side to side the alignment will have to be adjusted.
