If you wish to use the PLANEX for sanding walls in

cramped spaces, for example, reduce the length

of the machine by ﬁ tting the sanding head [1-1]

directly to the handle section [1-3].

When disassembling the machine, do not forget

to press the button [3-1] to release the contact

slide before opening clamping levers [2-1] and

[2-2].

7.2 Electronics

The machine features full-wave electronics with

the following properties:

Smooth start-up

The electronically controlled smooth start-up

function ensures that the machine starts up

smoothly.

Speed control

You can regulate the rotational speed steplessly

between 310 and 920 rpm using the adjusting

wheel [5-1]. This enables you to optimise the cut-

ting speed to suit the respective material.

Constant speed

The preselected motor speed remains constant

through electronic control. This ensures a uniform

cutting speed even when under strain.

7.3 Changing sanding pads

• Insert an Allen key (size 5) into the Allen screw

[6-1] on the sanding pad.

• Hold the sanding pad securely and turn the Allen

key to release.

In order to further ensure optimum axial run-out,

you must ﬁ rst clean the bearing surface for the

grinding disk on the driveshaft.

• Attach the new sanding pad.

• Tighten the screw [6-1].

Only attach speciﬁ ed sanding pads to the ma-

chine.

In order to guarantee optimum suction output,

the sealing face between the machine and the

grinding disk is ground in during the ﬁ rst few

minutes after the disk has been changed. Dur-

ing this time, the r.p.m. of the machine is slightly

lower and white foam particles form during the

grinding process. However, they do not damage

the machine.

7.4 Afﬁ xing abrasives

Compatible StickFix sanding discs are quick and

easy to attach to the StickFix sanding pad. Simply

press the self-adhesive sanding discs [1-4] onto the

sanding pad [6-2]. The adhesive coating holds the

StickFix sanding pad securely in position. Make sure

that the sanding disc holes line up with the suction

holes [7-3]. Tear off the sanding disc when worn.

7.5 Adjusting the internal/external extraction

You can switch between internal and external

extraction depending on the size of the particles

produced by the sanding process.

• Push the switch [7-1] to change between the two

dust extraction modes.

7.6 Adjusting the suction power

You can adjust the suction power to match the

surface type, but only when internal extraction is

active (see chapter 7.5).

• Use the adjusting wheel [5-3] to adjust the suc-

tion power.

1: Low suction power

6: High suction power

• Start with a low suction power (position 1) and

slowly increase until you can feel that the ap-

plication pressure has noticeably changed.

A high suction power makes sanding work on

ceilings and walls less tiring.

Excessive suction power can cause the machine

to vibrate and become more difﬁ cult to guide.

The machine may also be overloaded. This acti-

vates the protective circuit. The red diode ﬂ ashes

slowly. The electronic circuit switches to recovery

speed. If this happens, you must stop working

immediately until the machine has cooled down

again.

7.7 Sanding close to edges

The detachable brush segment allows you to re-

duce the distance between the wall/ceiling and the

side of the sanding pad.

• Press and hold the knob [9-1].

• Remove the brush segment [9-2].

There is a retainer in the lid of the SYSTAINER for

storing the brush segment.

• Hook in the brush segment at the opposite end to

the knob [9-1], swivel towards the sanding head

and engage into position.
