8. Check to see that coolant level is adequate
and turn on coolant pump if material to be cut
requires it. Machine should be filled with four
gallons of the proper coolant mixture. Follow
the directions on the product maker’s label and
fill the coolant tank through the chip tray area.
9. Do not start cut on a sharp edge.
10. Keep machine lubricated. See “Lubrication”
section.
12.0 Adjustments
12.1 Adjusting vise square to blade
1. Disconnect the machine from the power
source.
2. Place a machinist’s square on the table
against the blade and the vise. The square
should lie along the entire length of the vise
and blade without a gap.
3. If adjustment is necessary, loosen bolts
holding the vise and adjust vise so square
lines up properly. Tighten bolts.
4. Connect machine to the power source.
12.2 Changing blade speeds
Disconnect machine from the
power source before changing blade speeds.
Failure to comply may cause serious injury.
1. Disconnect machine from the power source.
2. Open pulley cover by supporting the belt cover
with one hand while removing the belt cover
lock knob with the other. Lower guard gently to
its full open position.
3. Support motor with one hand while loosening
lock handle (A, Figure 6). Lower motor gently.
Figure 6
4. Position belt in grooves according to the speed
selection chart.
5. Tension the v-belt by pushing down on the
motor and tightening the lock handle on the
motor tilt plate. Correct tension is achieved
when finger pressure on the belt between the
two pulleys causes approximately a 1/2"
deflection.
6. Close pulley cover and fasten.
7. Connect machine to the power source.
12.3 Adjusting feed rate
Rate of feed is adjusted by turning the cutting
pressure control knob on the control panel. Rate of
feed is important to band saw performance;
excessive pressure may break the blade or stall
the saw. Insufficient pressure rapidly dulls the
blade.
Material chips or shavings are the best indicator of
proper speed and pressure. The ideal chip is thin,
tightly curled, and warm to the touch. Chips that
range from golden brown to black indicate
excessive force. Blue chips indicate extreme heat
from too high a band speed which will shorten
blade life. Thin or powdered chips indicate
insufficient feed pressure.
Consult a Machinery’s Handbook or similar source
for speed and feed rate charts.
12.4 Changing blades
Disconnect machine from
power source before making any adjustments
or repairs. Failure to comply may result in
serious injury.
1. Disconnect machine from power source.
2. Raise saw arm approximately 6 inches. Hold
saw arm in place by closing cutting pressure
control valve. Remove screw (#145, sect.
14.1.2 and sect 14.1.3), washer (#146), and
brush (#147) from the wire brush post (#148).
3. Open both wheel covers and clean chips out of
both wheel housings. Loosen two lock knobs
and remove upper blade guard.
4. Release blade tension by turning blade
tensioning handwheel (A, Figure 7) counter-
clockwise until blade is free.
