Power Feed Test Run - Grizzly G0808 Owner's Manual

Power Feed Test Run

Model G0808 comes with power feed units for
X- and Z-axis table travel. Proper operation of the
limit switches (attached to the front middle of the
table and at the base of the Z-axis power feed
unit) is important to the operation of the power
feed units. Refer to Controls & Components,
beginning on Page 4, to understand the names
and locations of components referenced in this
section.
Both X- and Z-axis power feed units operate in a
similar way. Therefore, use the following instruc-
tions to test run both units. If either power feed
does not operate as expected during the following
steps, disconnect it from power and contact our
Tech Support at (570) 546-9663 for assistance.
During power feed operation, handwheels/
cranks will spin rapidly if engaged. To
reduce risk of entanglement or impact injury,
always disengage X-axis handwheel/Z-axis
elevation crank when using power feed.
Failure to do so could lead to entanglement
or impact injuries.
To test run power feed units:
1.
Make sure all tools, cables, and other items
are well clear of table movement and potential
direction of travel.
2. Refer to Operating Power Feed section,
beginning on Page 28, to understand how
power feeds, table locks, and limit switches
function.
3. Adjust limit stops to allow for maximum table
movement in following steps.
4. Loosen all applicable table locks.
5. Plug X-axis power feed power cord into a
matching power supply receptacle.
6. Make sure power feed direction lever is in
neutral (middle) position, turn speed dial
counterclockwise to lowest setting, then
move ON/OFF switch to ON position.

7. Move direction lever to left, slowly turn speed
dial clockwise to increase speed, then con-
firm that table is moving to the left.
8. Press and hold Rapid Traverse button for
a few moments to confirm rapid traverse is
operating correctly. Table should move rap-
idly to the left.
9.
Release Rapid Traverse Button. Table should
resume normal speed.
10. Allow table limit stop to hit limit switch. Table
movement should stop.
— If table movement does not stop, Turn OFF
power feed and DISCONNECT POWER
IMMEDIATELY. Contact Tech Support.
11. Move direction lever through neutral (middle)
position and all the way to the right. Table
should begin moving in opposite direction.
12. Allow table limit stop to hit limit switch. Table
movement should stop.
— If table movement does not stop, Turn OFF
power feed and DISCONNECT POWER
IMMEDIATELY. Contact Tech Support.
13. Repeat Steps 11–12 with table moving in
opposite direction.
14. Move direction knob to neutral (middle) posi-
tion, turn speed dial to lowest setting, and
press OFF button.
15. Retighten table locks.
16. Loosen Z-axis table lock, then repeat this
same Test Run process with Z-axis power
feed unit.
Congratulations! The Test Run is complete.
