20
WARRANTY
Each
GraverMach AT,
including handpieces and foot
control, carries a full 2-year warranty covering parts and
labor. Call for a Return Goods Authorization (RGA) number
before returning any equipment.
These products are designed for reliable operation using
most sources of compressed air. However, some air supplies
contain excessive water, oil, dirt, rust, or other contaminants.
The unit’s built-in filter is a final filter to protect against
normal dirt and water. If your compressed air has excessive
contaminants, you should install the necessary filter(s) and
water trap(s) ahead of your unit.
Oil contamination can be gradual and subtle. If you notice
an oil residue (usually a yellow to brown colored sticky or
liquid residue) in the unit’s filter bowl or handpiece / throttle
hose, you probably have an oil problem in your compressed
air. Older oil lubricated and “silent” compressors that use
internal oil are more likely to cause oil contamination.
If this occurs, install a Coalescing Oil Filter (GRS #004-579
or equivalent).
NOTE: Damage caused by contaminated compressed
air is not covered by the warranty.
