1. Introduction 

Before use, operators must be provided with information, instruction and training for the use of 

the machine and the substances for which it is to be used, including the safe method of removal 

and disposal of the material collected. All persons who are working with or maintaining this 

machine must read the manual carefully and understand it fully. In case you sell the unit, hand it 

on to the next owner. 

Keep this manual always with the machine, to enable it to be referred to at any time. 

Any other work not covered by this operating manual must not be carried out. Always use 

common sense when working with machines. 

 

This machine is designed for industrial use by professionals. Only authorized and trained personnel may 

operate this machine. This machine is not intended for use by persons (including children) with reduced 

physical, sensory or mental capabilities, or lack of experience and knowledge. 

Blastrac BV

 offers a course on 

the use of the machine in order to make the operating and maintenance personnel familiar with all elements of 

the machine. 

 

2. Machine description 

 

The Blastrac multisaw machine BMC-335 is supplied with a 400 Volt electric motor where you can mount 

different quantities of saw blades underneath. By changing the pulleys and the belt, the machine can also be 
used as a scarifier. The manufacturer will not be liable for damage resulting from incorrect usage, in these 

cases the user assumes all risks. 

The machine is available with optional remote control system.  

 

The machine is sealed around which makes the use almost dust free when connected to an appropriate 

Blastrac dust collector. Due to the fine adjustment and the possibility to lock the height adjustment, the depth 

of cutting can be set very precisely, and the same saw depth can be maintained. 

  

Intended use: 

  

 

The multisaw machine is extremely suitable for removing hard top layers from soft floors or to remove the top 

layer from “floating” floors and/or “computer” floors.

 

Sawing is ideal for removing several millimeters from a concrete floor preparing it to be polished up to the 

stones without using an extra scarifier. 

The BMC-335 can be used during sawing in the forward or backward driving direction. (Depending on the way 

the blades are mounted). 
 

NEVER use the BMC-335 as a scarifier without the proper modifications. 

The machine must first be converted into a BMP-335.  

 

This is possible by changing the belt and the pulleys. 

If the multisaw machine is converted to a scarifier, it can be used, with the appropriate cutters, for the 

following applications; 

To roughen concrete 

To clean most horizontal surfaces 

To remove coatings 

To corrugate concrete surfaces 

To remove road markings 

To make non-slip surfaces 

 

The force of impact of a cutter is controlled by the depth adjustment. With the right depth adjustment, the 

best performance is obtained to give a desired result. 
 

With a suitable Blastrac dust collector work can be carried out without causing excessive dust in the work area, 

this raises the life span of the machine and protects the health of the personnel.
