Removing the workpiece
The workpiece is damp and slippery from the
thread oil. Carefully ensure that it does not
slip out of your hands and drop onto your
feet when you remove it from the machine!
Turn the feeder hand wheel clockwise and move
back the tool carriage. Release the clamping
chuck.
Release the centering chuck and pull out the
workpiece.
Cleaning after use
Do not remove metal and plastic chips using
compressed air!
There is a risk of eye injuries and loss of
eyesight!
Do not pick up sharp-edged metal chips
with your bare hands! Risk of injury! Wear
protective gloves!
Remove chips from on and around the machine.
Use a wire brush to remove chips from and clean the
clamping chuck, the thread jaws of the thread head
and the internal deburrer.
Use a cloth to wipe thread oil splashes from the
machine and the workplace.
Maintenance and
inspection
All machines are subject to natural wear during use.
They must be maintained from time to time and
wear parts must be replaced.
This work may only be carried out by an authorized
ROTHENBERGER service center. This gives you a full
warranty on the material and workmanship!
If the machine is being cleaned, maintained,
inspected or repaired, it is essential to switch it off
and to unplug!
Always avoid uncontrolled starting-up of the
machine. Risk of injury and accidents!
Threading oil maintenance:
Change threading oil every 40 hours of use or
when threading oil has become contaminated or
dirty.
To drain oil, position a container under drain plug
and remove plug.
When oil has drained out use a rag to clean oil
sump of chips and sediment. Remove all debris
around oil filter.
Replace drain plug and pour (3-4l / 1 gallon) of
ROTHENBERGER-oil into oil sump.
Carriage rails and gear:
Keep clean and oil frequently with machine oil.
Ring gear:
Remove spindle cover and check ring gear every
six months to see if additional high temperature
graphite gear lubricant needs to be applied.
Motor:
Check motor for brush wear every six months. If
motor lacks power due to a dirty commutator, use
a commutator cleaner stick or fine emery cloth.
Lubrication is not required as all motors have sealed
ball bearings.
Gear case:
It is permanently lubricated and requires no
maintenance
Brake band:
If slippage of stock should occur after wire brushing
jaws, then:
Stop the machine.
Remove spindle cover.
Tighten brake adjustment bolt. Start machine.
