SANDPAPER SELECTION

Selecting the correct size, grit and type of sand paper is an 

extremely important step in achieving a high quality sanded 

finish. Aluminum oxide, silicon carbide, and other synthetic 

abrasives are best for power sanding. Natural abrasives, 

such as flint and garnet are too soft for economical use in 

power sanding.
In general, coarse grit will remove the most material 

and  finer  grit  will  produce  the  best  finish  in  all  sanding 

operations. The condition of the surface to be sanded will 

determine which grit will do the job. If the surface is rough, 

start with a coarse grit and sand until the surface is uniform. 

Medium grit may then be used to remove scratches left 

by the coarser grit and finer grit used for finishing of the 

surface. Always continue sanding with each grit until 

surface is uniform.

 WARNING

Do not use sander without sandpaper; doing so will 

damage the cushion.

MAINTENANCE

 WARNING

The product should never be connected to a power 

supply  when  assembling  parts,  making  adjustments, 

cleaning, performing maintenance, or when the product 

is not in use. Disconnecting the product from the power 

supply will prevent accidental starting that could cause 

serious injury.

 WARNING

When servicing, use only original manufacturer’s 

replacement parts, accessories and attachments. Use of 

any other parts may create a hazard or cause product 

damage.

 WARNING

Do not at any time let brake fluids, gasoline, petroleum-

based products, penetrating oils, etc., come in contact 

with plastic parts. Chemicals can damage, weaken or 

destroy plastic which may result in serious personal 

injury.

■

Avoid using solvents when cleaning plastic parts. Most 

plastics are susceptible to various types of commercial 

solvents and may be damaged by their use. Use clean 

cloths to remove dirt, carbon dust, etc.

■

Always wear safety goggles or safety glasses with side 

shields during power tool operation or when blowing 

dust. If operation is dusty, also wear a dust mask.

■

If the supply cord is damaged, it must be replaced 

by a special cord or assembly available from the 

manufacturer or its service agent.

■

For greater safety and reliability, all repairs should be 

performed by an authorised service centre.

 WARNING

Electrical  tools  used  on  fiberglass  material,  wallboard, 

spackling  compounds,  or  plaster  are  subject  to 

accelerated wear and possible premature failure 

because  the  fiberglass  chips  and  grindings  are  highly 

abrasive to bearings, brushes, commutators, etc. We do 

not recommend using the product for extended work on 

these types of materials..

 WARNING

Do not use compressed air to blow dust from the product. 

This practice is dangerous and can cause dirt and grit to 

be blasted into someone’s eyes, causing injury.

LUBRICATION

All of the bearings in the product are lubricated with a 

sufficient amount of high grade lubricant for the life span of 

the product under normal operating conditions. Therefore, 

no further lubrication is required.

CLEANING THE SANDING SHEETS

The sanding sheets that come with the product are made to 

be re-used. Therefore, it is important that they be cleaned 

periodically to remove sanding residue and foreign material 

that can accumulate over time. 
To clean sanding sheets, rub the sheets with a hard rubber 

block. You can also use the clean rubber sole of a shoe.

ENVIRONMENTAL PROTECTION 

Recycle raw materials instead of disposing 

of as waste. The machine, accessories and 

packaging should be sorted for environment-

friendly recycling.
