7.2 Machine Operation
Prior to machine set-up or performing any adjustments, repair work,
or trouble shooting, it is very important to check the applicable
safety functions to ensure they are all in proper working condition.
To operate and adjust the machine, follow these steps.
WaRninG
Disconnect the machine from its power source.
Step 1:
Adjust V-Belt Tension
Re-check the v-belt tension weekly for the first 3 months of
operation. There should be a small amount of deflection in the belt
when pressing it midway between the pulleys. Adjust if necessary.
Check tension periodically as belts may gradually stretch over time.
1. Detach the belt cover by removing the 3 cap nuts with an Allen
wrench.
NOTE: Leave the hex nuts and flat washers on the threaded rods in
place. They keep the belt cover from bending during tightening.
2. Loosen the lower hex nut on the motor base with an Allen
wrench.
3. Turn the top hex nut clockwise until proper belt tension is
achieved.
4. Retighten the lower hex nut.
5. Replace the belt cover.
The motor and belt
drive are located behind
the cover on the right
side of the machine.
Step 2:
Check the Cutterhead
WaRninG
The knives in the cutterhead are very sharp. Handle with extreme
care when cleaning, sharpening, or replacing.
The spiral cutterhead
is equipped with a set
of 60 carbide inserts
that house the jointing
knives.
The cutterhead should be inspected before each operation. Be sure
the carbide inserts are secure and not chipped in any place. Loose
or damaged inserts may be thrown from the machine and pose
extreme danger. Chipped or missing inserts can cause imbalance in
the cutterhead and lead to bearing failure.
Also check the knives for sharpness. The knives are two sided
and can be rotated when dull. Once both sides of a knife are dull,
the carbide inserts should be replaced. To obtain replacements,
call Stiles Parts Dept. at 1.800.727.8780. Reference part
# 56-010-12005.
