OPERATIONAL TIPS

OPERATIONAL TIPS

After reading the previous chapters carefully, 

apply these tips scrupulously to obtain maximum 

performance.

Proceed calmly so as to become familiar with 

all the controls; after having gained sufficient 

experience you will be able to make full use of 

its potential.

ABRASIVE SUPPORT

Use the suitable abrasive support for the sanding 

operation to be carried out. The choice depends 

on the material to be processed and the required 

finishing degree; there are different types on 

the market marked with a number defining the 

surface “grain”, printed on the back. Ask your 

retailer to give you the best advice on this.  Our 

company produces a wide range of abrasive 

supports suitable for the various uses.

SANDING OPERATION  

- Before working on important objects (e.g. furni-

ture, vehicles, etc.) do a sanding test to ensure 

you have installed the right abrasive support.

- If the item is small and light always fasten it 

with a vice while working; if it is not fastened 

well, the action of the machine could throw it 

against you. 

- Do not work on damp or wet items or with wet 

abrasive supports.

- Initially use an abrasive support with a coarse 

grain (e.g. 40), then finish processed surfaces 

with a finer grain abrasive support (e.g. 120 

or higher).

- Make sure the abrasive support is correctly 

assembled and perfectly flat against the orbital 

plate.

- Always use the sander connected to a vacu-

um system with a filter for dust or to the bag 

provided.

- Only start the sander once you have a firm 

grip on the handle(s). Rest it on the item and 

operate it with circular movements exerting 

light pressure. Do not insist on sanding one 

point keeping the machine still. 

- Excessive pressure with the hand(s) on the 

sander does not improve its performance and 

causes a risk of the motor overheating with 

subsequent breakdowns not covered by the 

warranty, or can cause fire due to the high 

temperatures produced on the item.

- Do not cover the sander’s ventilation slots with 

your hand(s). 

- Replace the abrasive support as soon as it 

is worn or deteriorated; do not let the sander 

work under excessive loads, avoid damaging 

the backing plate and you will obtain a better 

result with less effort and time.

MAINTENANCE

!

IMPORTANT! Before any inspection, 

adjustment or maintenance, always discon-

nect the battery from its housing.

!

IMPORTANT! Do not tamper or attempt to 

repair the electrical tool.

The working life and costs also depend on con-

stant and meticulous maintenance. 

Take good care of your electrical tool and clean it 

regularly. In this way its efficiency will be ensured 

and its lifespan extended.

- Remove dust and machining residuals with a 

brush with soft bristles.

- Do not wet or spray water over the electrical 

tool - risk of internal infiltrations.

- Do not use any inflammables, detergents or 

solvents.

- The plastic parts can easily be damaged by 

chemical agents.

- Do not use compressed air for cleaning: Risk 

of material ejection!

- Pay particular attention to cleaning the switch, 

the motor ventilation slots, the holes on the 

backing plate and the abrasive support driving 

rollers. 

- Open the dust box cover (fig. G) to empty the 

contents. Clean the inside with a small brush 

and reassemble.

- Remove any traces of wood resin.
