3.2 Correct shear blade adjustment

Adjust as follows when placing into operation:
Prior to clipping: With switched off machine (fig. 1). After mounting the shear blade, turn the tensioning nut until you feel a noticeable re-
sistance. Ensure that the tapers of the pressure fork mate with the holes in the upper blade (fig. 3, pos. 2). Ensure that the teeth tips of the
upper blades are located approximately 1,5 – 3,5 mm behind the polished area of the lower blades (fig. 8). Oil the shear blades before use.
You can now start to use the shears. Loosen the tensioning nut until the shear blade has hardly any contact pressure anymore. Important
note: The upper blade can fall out, if the tensioning nut is opened too far. Slowly tighten the tensioning nut (fig. 3, pos. 1, direction Z)
until you detect some resistance. Continue to turn the tensioning nut by max. 1/8 rotation. Start to clip. Reset the tensioning nut somewhat,
if the cut is not satisfactory (direction Z). The factory has fully adjusted shipped shears for clipping.
During clipping: Do not tension the shear blade too much. The tensioning nut must be slightly tightened during clipping from time to time
(max. 1/8 rotation).

3.3 Correct clipper head oiling

The most frequent error cause for a non-satisfactory clipping result as well heating up of the clipper is want of lubrication. A light oil film on
the shear blades is essential for an optimal clipping result as well as to increase the service life of the shear blades and machine. All other
moving parts of the clipper head must also be well lubricated. Drip oil on the shear blades and into the oil opening of the clipper
head every 5 – 10 minutes (fig. 2), so that these do not run dry. Only use our special clipper machine oil.

3.4 Turning on/off

The slide switch has two positions (fig. 1, pos. 1 shows position 0)
Position 1: Machine is turned on
Position 0: Machine is turned off
Check the switch position before plugging in. The switch must be in position 0. Only use the slide switch for turning the machine on and off.

3.5 Malfunction motor protection switch

The motor protection switch protects the clipper against too high mechanical and electrical loads. Turn the machine off with the slide switch
(fig. 1, position 0), if the motor protection switch button (fig. 1, pos. 2) jumps out (the machine stops). Immediately disconnect the
plug from the mains. The reasons for the motor protection switch button jumping out can be: the shear blades are tensioned too strongly,
defective motor, the clipper head is blocked etc. After a short cooling off period, the clipper can be re-started by lightly pressing the motor
protection button until it clicks back.
