USE INSTRUCTIONS.

Before starting up the concrete wall planer, we 

recommend that you carefully read all of the 

instructions as indicated.

Please respect all 

regulations regarding the prevention of accidents, 

health and safety directives, laws and applicable 

restrictions for work places.

The concrete wall 

planer must only be used by persons who have 

been instructed in its use and only for the purposes 

for which it has been designed.

POWER SUPPLY.

Make sure the power supply is adapted to the 

requirements shown on the information panel of 

the concrete wall planer (1).

Using the motor at low 

voltage will make it operate slowly.

This will reduce 

performance and may cause the motor to overheat.

EXTENSION CORD.

If the working area is at some distance from the 

power supply, use an extension cord of enough 

diameter and quality.

ADVANTAGES.

The concrete wall planer includes soft start, 

constant power control and overload protection.

Soft start protects the motor from excessive current 

shock and enlarges motor lifetime.

Constant power 

control ensures stable power while the concrete 

wall  planer  works  with  different  loads.

With the 

overload protection, the concrete wall planer will 

automatically shut down if it is overloaded, which 

prevents the motor to be burned. 

CONNECTING TO AN EXTERNAL VACUUM SYSTEM.

The concrete wall planer can be connected to an 

external vacuum system to collect the dust produced 

during the planing process.

To  do  so,  first  make 

sure that a suitable bag is fitted inside the vacuum 

(not supplied) for collecting plaster and mortar.

Installing an unsuitable or defective dust collection 

bag will increase the amount of dust in the working 

area.

Prolonged exposure to high concentrations of 

dust may affect the respiratory system.

Connect a 

vacuum hose to the concrete wall planer .

It is not 

advisable to use the concrete wall planer without 

first  connecting  a  dust  collecting  system,  as  this 

may cause breathing problems.

CARBIDE BLADE REPLACEMENT.

Unscrew the 4 lateral screws with a screwdriver 

and  gently  take  off  the  aluminum  cover  (2).

Use 

a socket wrench to loosen and open the spiral 

blades, one by one (3).

Attention!.

To replace the 

most inner blade, don’t leave the pin (4).

Assemble 

the new blades (5) and close the aluminium cover 

again with the 4 lateral screws.

HEIGHT ADJUSTMENT.

When the height adjuster is at the same level of 

the steel plate, the concrete wall planer is at the 

maximum height of scouring, which is 3,5 mm.

The 

calibration can be done with the rotation button.

Each small cell is for 0,06 mm, each big cell is for 

0,33 mm and one loop is for 1 mm.

While scouring 

concrete, cement, granite or other hand materials, 

it is suggested to use the lowest depth.

LOCK-ON BUTTON.

The concrete wall planer is fitted with a blockade 

button system.

For it press the switch and then 

press the lock-on button (6).

Just by to return to 

press the switch you will disconnect the automatic 

blockade .

Attention!

.

In case of every stop or a 

power cut, the lock-on button has to be released 

immediately by pressing the on/off switch, in order 

to avoid an unintentional restart.

MAINTENANCE.

The concrete wall planer has been designed for 

a long working life with minimum maintenance.

Optimum use depends on correct care of the 

concrete wall planer and regular cleaning.

To prevent 

accidents, always unplug the concrete wall planer 

from the power source before cleaning or performing 

any maintenance.

The concrete wall planer may be 

cleaned effectively using compressed air after each
