Erasers, Continued
Electric erasers
Electric erasers are hand held units with power cords or rechargeable bases.
They provide rapid and thorough erasures.
The eraser nib is
interchangeable depending on the degree of hardness you require to erase the
medium.
To use an electric eraser, follow this table:
Step
Action
1
Select the appropriate eraser nib for the media you are using.
2
Secure the nib into the shank of the electric eraser.
3
Isolate the unwanted area or protect surrounding areas with an
erasing shield.
4
Turn on the eraser and lower over the error.
5
Move the eraser in a circular motion over the erasure taking care
not to hesitate in one spot for long. Allowing the eraser to sit in
one spot too long will bore a hole through the paper and bum the
vinyl table covering.
6
Remove the eraser from the drawing surface.
7
Brush away the residue with a draftsman’s brush.
