Installing Handwheels; Assembling Knife-Setting Gauge (Jj-8Cs Only); Installing V-Belts - Jet JJ-8CS Operating Instructions And Parts Manual

Installing Handwheels

1. Remove protective tape from shaft, and
remove screw and washer.
2. Press handwheel (A, Fig. 4) onto shaft,
aligning the keyway with the key.
necessary, use a hammer with a block of
wood to tap the handwheel completely onto
the shaft.
3. Re-install screw and washer (B, Fig. 4).
4. Mount handle (C, Fig. 4) onto handwheel.
Assembling Knife-Setting Gauge (JJ-
8CS only)
Place the two bases (A, Fig. 5) onto each end of
the bar (B, Fig. 5). Snap the four E-rings (C,
Fig. 4) into the grooves on the bar as shown,
one E-ring on each side of a base.

Installing V-Belts

1. Disconnect the machine from the power
source, unplug.
2. Remove the lock knob (A, Fig. 6) and belt
guard (B, Fig. 6).
3. Place v-belts onto cutterhead pulley grooves
and through opening in stand.
4. Pull v-belts down and place onto motor
pulley (Fig. 7). If necessary, loosen the
mounting screws (A, Fig. 7) and slightly lift
motor. Re-tighten the screws when belt is
placed.
5. Check to make sure that motor pulley and
cutterhead pulley are vertically aligned and
the v-belt does not contact the sides of the
opening in the base. If the pulleys are not
aligned, loosen the screws (A, Fig. 7) on the
motor base and slide the motor until the belt
is aligned. Re-tighten screws.
6. The v-belt is properly tensioned when finger
pressure on the belt half way between the
two pulleys causes 1/2" deflection. If the belt
is too loose, loosen the lower screws (B,
Fig. 7) on the mounting plate and push
down on the plate. When belt tension is
correct, re-tighten screws.
7. After two hours of operation, check belt
tension again. Re-tension if necessary.
8. Re-install belt guard and lock knob.
