Halfnut Adjustment; Feed Clutch Adjustment - Grizzly G0600 Manual Insert

Halfnut Adjustment

When adjusting the halfnut gibs remove the
thread dial to expose the two gib screws (Figure
104). Your goal is to remove sloppiness in the
ways without causing the half nut to bind. You will
loosen the jam nuts and turn the two set screws
clockwise until slight tension is felt in the set
screw. The gibs will then be slightly pre-loaded.
Tighten the jam nuts when finished.

Feed Clutch
Adjustment
This lathe is designed with a feed clutch. This
cone type clutch helps protect the apron feed
system from overload. The feed clutch comes set
from the factory. However, after the lathe becomes
broken in, you may have to readjust this setting.
To adjust the clutch release point:
1. Using a 5mm hex wrench, turn the center
cap screw clockwise to increase the clutch
holding power, and turn counterclockwise to
decrease the clutch holding power (Figure
105).
2.
Start the lathe.
3.
Engage the power feed and hold the lon-
gitudinal feed handwheel with one hand.
The clutch should release within a few sec-
onds without you fighting handwheel rotation.
When it does, the holding force is approxi-
mately 12 kg.
4.
Readjust the clutch screw as required to
achieve the 12 kg setting.
