Adjusting Table Supports
1. If the conveyor table does not rise and lower
easily, measure the distance between the top
of the base column support and the bottom of
the table support on both the inboard and the
outboard side of the machine. See Figures 29
and 30.
2. Compare these measurements; they should be
within 1/16”. If they are not, disengage the
miter gear on the inboard side of the transfer
rod (Figure 29) by prying off the protective cap
with a screwdriver and loosening the set-screw
in the gear’s collar.
3. Adjust the conveyor table height using the
height adjustment handle to get the same
measurement on both sides. Then re-engage
the miter gear on the transfer rod, tighten the
set-screw, and replace the protective cap.
If the conveyor table is still difficult to raise or lower,
the table supports may need to be re-centered on
the columns. To do this, loosen the four 3/8”x1” hex
head bolts in each table support that connects it to
the table mounting brackets, adjust and tighten the
set-screws (Figure 3) to hold the table support in
position. Then tighten the hex head bolts and re-
loosen the set-screws. Re-align drum (see
page 18).
Replacing V-Belt
1. Unplug machine from power source.
2. Remove the outer half of belt guard by
removing the six #10-32 screws with a 5/16”
wrench. Slide the belt guard away from the v-
belt. See Figure 31.
3. Use a flat blade screwdriver to pry off the
protective cap over the inboard miter gear, and
loosen the set-screw in the gear’s collar.
Remove the miter gear and loosen outboard
collar (Figure 32). Slide cross bar toward
outboard side as shown.
4. Loosen v-belt tension by loosening pinch bolt in
motor support (Figure 32) and raise motor.
Remove v-belt from pulleys.
5. Install new v-belt and tension the belt by using
the weight of the motor only. Make sure the
pulleys are aligned. Replace transfer rod and
miter gear; tighten set-screw on miter gear and
replace protective cap. Tighten collar on
transfer rod.
6. Install the outer half of the belt guard and
tighten the six screws.
