Grizzly G1021 - Manual (Page 31)

G1021 15" Planer -31-
Once the assembly is complete and the adjust-
ments are done to your satisfaction, you are
ready to test the machine.
Turn on the power supply at the main panel.
Press the START button. Make sure that your fin-
ger is poised on the STOP button, just in case
there is a problem. The planer should run
smoothly, with little or no vibration or rubbing
noises. Strange or unnatural noises should be
investigated and corrected before operating the
machine further.
Test Run
WARNING
DO NOT attempt to investigate or adjust the
machine while it is running. Wait until the
machine is turned off, unplugged and all
working parts have come to a rest before
you do anything!
WARNING
Always wear ANSI-approved safety glasses
or goggles when operating equipment —
particularly when testing new tools or
machinery. Do not allow visitors into your
workshop when testing or operating equip-
ment.
If noises occur that cannot be found by visual
inspection, feel free to contact our service depart-
ment for help.
The species of wood, as well as its condition,
have a dramatic effect on planing ability. The
harder the wood (as illustrated by its shear
strength), the more difficult it will be to plane. A
brief listing of common hard and soft woods in
relation to their shear strengths and planing diffi-
culty is listed below.
