Handheld Sander Introduction
Let's begin! First off, make sure you have read the machine's manual (should be linked from its wiki page).
- lots of fine dust from wood or plastics - can irritate lungs and skin
- sparks from metal
- powerful movements can make the workpiece shift (or fly!) and let a handheld sander "run away"
- some of the sanders have no prevention of turning on after loss & restoration of power (keine Anlaufsicherung)
- wear a dust mask and long clothes if your material generates hazardous dust
- sand outside if you can't connect a shop vac or fine filter
- when sanding metal, do NOT connect dust collection - the sparks could cause a fire!
- wear goggles when working with metal or small workpieces
- ear defenders and gloves are also recommended when working with the sander (and shop vac) for an extended amount of time
- secure your workpiece and exert a firm grip on the tool
- check for a clean run and fit of the sanding medium before you start; check if hole alignment for the dust extraction is correct
- let the tool get to full speed before contacting your workpiece and start with light pressure
- make sure the tool is turned off before plugging it in
- do not blow the workpiece clean when you're done, best clean it with a moist towel
Protect the Velcro
Do NOT sand with parts of the velcro pad uncovered - this will wear it out and lead to much poorer bonding of the next piece of sandpaper!
Besides these safety notes, you should read the page about dust to get a better conception of the dangers associated with some materials! Remember, you are responsible for the material you choose and for protecting yourself.
