Operating and maintenance manual

2.6.1 alkitronic® CLD/L, CLD, CLS, CLS2

During operation, always hold the alkitronic® CL

multiplier in the axial direction (6) towards the nut,

otherwise this increases the risk of deformation /

damage to the standard nut / connector (4) or the

screw / nut which is to be loosened. Furthermore,

a secure counter-support (5) is no longer guaran-

teed. (Fig. 4)

Safe support only in the area displayed

For the correct tightening and loosening of screw connec-

tions, the following steps are to be carried out (Fig. 4):

• alkitronic® CL with standard nut / connector (4), place

fully on screw / nut

• The outrigger (DMA) of the alkitronic® CL must absorb

the reaction moment at the height of the standard nut /

connector (4)

• A secure, stable counter support (5) must be ensured

• Always hold the alkitronic® CL in axis (6) to the bolt dur-

ing the process

• After pressing the rocker switch (3) for clockwise or anti-

clockwise rotation, the motor stops when the desired

torque is reached:

a) Counterforce = Motor power

b) Counter torque = Motor torque

c) Predetermined torque is reached

• Change the direction of rotation

• Switch on the machine briefly until the outrigger is free

• Switch off the motor

• Remove the machine, put on the next bolt / nut

• Repeat the tightening procedure

2.6.2 alkitronic® RCL

Insert the support pin (8) completely into the

intended fixture (s) of the alkitronic® RCL housing

to prevent damage to the housing.

Secure support only with supporting bolts

fully inserted in the housing shells

The tightening and loosening of screw connections must

be carried out in principle as with multipliers using an axial

downforce. Due to the radial downforce of the alkitronic® RCL

however, the multiplier is to be operated at a 90 degree angle

to the screw axis (6). The output occurs via a fixed wrench size

(4). In order to reduce to smaller wrench sizes, alkitronic® STA

(7) should be used. A support pin (8) is used as a torque trans-

ducer. A secure, stable counter support (5) must be ensured

(Fig. 5). (See also application drawing Fig. 6.)
