The chip drawer catches swarf and metal
chips during operation. A screen in the bottom
prevents large chips from returning to the
reservoir with the run-off coolant, which could
cause damage to the pump.
The chip drawer slides open and is removable for
cleaning (see Figure 83).

The chip drawer is very heavy. Unless
removing the chip drawer for cleaning, do
not pull it out more than halfway; otherwise,
it could fall out and cause a crushing injury.
If removing the drawer for cleaning, get
assistance!
