3.4. Cutting Nipples and Double Nipples
REMS Nippelfix (automatic inside clamping) or REMS Nippelspanner (inside
clamping) are used for cutting nipples. Make sure that the pipe ends are deburred
on the inside. Always push on the pipe sections as far as they will go.
To clamp the pipe section (with or without thread) with the REMS Nippelspanner,
the head of the nipple tightener is splayed by turning the spindle with a tool.
This may only be done with the pipe section fitted.
Makes sure that no shorter nipples than the standard allows are cut with the
REMS Nippelfix and the REMS Nippelspanner.
3.5. Cutting Left-handed Threads
Only REMS Magnum 2010, 2020, 4010 and 4020 are suitable for left-handed
threads. The die head in the tool carrier must be pinned with an M 10 × 40 screw
for cutting left-handed threads, otherwise this can lift and damage the start of
the thread. Set switch to position "R". Switch over the hose connections on the
coolant-lubricant pump or short circuit the coolant-lubricant pump. Alternatively,
use the changeover valve (Art. No. 342080) (accessory) which is fixed to the
machine. The flow direction of the coolant-lubricant pump is reversed with the
lever on the changeover valve (Fig. 9).

The gear of the REMS thread cutting machine is maintenance-free. The gear
runs in a closed oil bath and therefore needs no lubrication. Keep the clamping
and guide chucks, guide arms, tool carrier, die head, dies, pipe cutter and pipe
inside deburrer clean. Replace blunt REMS dies, cutting wheel, deburrer blade.
Empty and clean the oil tray from time to time (at least once a year).
Clean plastic parts (e.g. housing) only with the REMS CleanM machine cleaner
(Art. No. 140119) or a mild soap and a damp cloth. Do not use household
cleaners. These often contain chemicals which can damage the plastic parts.
Never use petrol, turpentine, thinner or similar products for cleaning.
Make sure that liquids never get inside the REMS thread cutting machine.
