Powerful single-phase fixed speed sander suitable for performing heavy sanding and preparation treatments on certain types of civil and industrial floors. Dual functionality of sander and single disc machine easily interchangeable.

The LEADER MACHINE is the largest single-phase professional sander in our range and the first designed by LMA. It guarantees high performance and can withstand enormous stresses and consecutive hours of work, despite its mighty weight and single-phase power supply. It is suitable for sanding, even heavy, and for the preparation of civil and industrial floors in marble, concrete, granite, terrazzo and natural stone. Excessive vibrations during machining, differences in planarity on the work surface and voltage overloads are minimized.

With a few simple gestures it can be transformed from a sander to a single disc machine, making it the most powerful professional single disc machine in its category.

Model without speed variator (fixed speed) particularly suitable for those who do not need to use the machine on several fronts but only a specific type of flooring. In this way you have the opportunity to combine power and performance at a more limited cost.

Features:

• Strengths
  • Powerful single-phase 4HP
  • The crown and the reduction gear, firmly tightened to the frame, allow the motor flange and the gear plate to become a single body with the machine. This allows the maximum power transfer of the motor to the action of the treatment and a great reduction of the vibrations during the working
  • Exposed self-lubricating gears. Made of Teflon with straight teeth, they allow the operato to make cleaning, maintenance and replacement of the Gear Plate easier. It does not require greasing
  • Cushioned carcass: an innovative frame cushioning system, patented with international deposite, allows the operator not to tire during daily work
  • Gear handle
  • Aluminum tank holder
  • Practical reclining lever and support block allow you to place the machine damaging the electrical box 
  • Ergonomic operating levers on the handles allow the operator to orient the Leader Machine in height and depth. The result is greater comfort when machining even the most difficult surfaces.
  • Omnidirectional balls fixed on the suspension frame, and bearings, allow a quick change of direction and easier steering than traditional wheels
  • Cage with drainage channel to expel debris and fluids
  • Transport trolley with Ø150mm non-marking wheels fixed on the amortized frame. Allows for effortless transport on delicate floors with minimal damage
  • Only 15cm in height between the machine casing and the tool (half that of the competition) allows you to get into tight spaces.
  • Equipped with 10m of neoprene cable and practical cable reel
  • Convenient 220V outlet socket
  Usage
  • A quick gear plate removal mechanism allows the LEADER MACHINE to become a single brush in seconds. The methods of use are therefore as follows:
  • Single -phase sander for sanding and preparation of floors
  • Single-phase single - disk machine for washing, cleaning, polishing or treating floors
  • Type of surfaces: civil and industrial floors
  • Fixed motor speed therefore particularly sutiable if used regularly on the same type of floor
  • Surfaces: marble, concrete, granite, terrazzo and natural stone
  • Removal of existing resings, paints and adhesives
  • Possibility to carry out even heavy and heavy work
  • The reduced height of the casing allows an optimal approach even in small spaces such as under radiators and under stairs
  • Optimal flush-to-wall sanding
  • It adopts perfectly to surfaces with differences in planarity and reduces electrical voltage overloads
  • Easily maneuverable
  • Comfortable for the operator thanks to low vibrations
  • Quick and safe tool change without the use of wrench or hammer
  • Easily transportable
