The item numbers specified for the corresponding individual
components relate to chapter drawings.
Check whether the jaw guides and the piston of the ROTA TB2
power chuck are sufficiently lubricated at the lubrication nipples
countersunk into the base jaws; otherwise use LINO MAX special
grease to lubricate the base jaws in retracted position.
An insufficiently lubricated chuck loses significant clamping force.
On the front face side of the chuck there is a hexagon socket
locking screw, size 6.
Behind the locking screw (15) the pilot-controlled double check
valve controls the pressurization and ventilation of the two
pressure chambers and shuts off the pressure toward the outside.
It is very important to lightly lubricate the bore hole of the valve
system with Klüber special grease QNB 50/100, to ensure a
smoothly operating valve system. Excessive grease as well as
impurities in the valve bore significantly impair the function of the
chuck and should be avoided.
CAUTION
During actuation of the clamping device (clamping or releasing)
it must be ensured that a short ventilation time is maintained
between the switching processes. This ventilation time must last
at least 0.5 seconds, depending on the hose length. For this
purpose we recommend the use of a 4/3- or 5/3- way valve
(central position depressurized).
