FEATURES AND CONTROLS (FIG. 2)
SPEED AND FEED CHART: The speed and feed chart mounted on the upper door of the saw enables the operator
to quickly select the correct saw band, speed and feed rate on the chart for basic materials
TABLE: A heavy duty table and trunnion assembly will hold 200 lbs (91.72kg) at any point or 500 lbs (226.8kg) evenly
distributed. The table can be tilted 150 left or 450 right. Pointer and degree scale are attached directly to the trunnion and
cradle to indicate the angle at which the table is set.
SAW WHEELS: The wheels are cast iron, dynamically balanced, centered and aligned so that the band will run at all times
against backup bearings and centered on wheels. Tires are vulcanized to the wheels assuring no slippage and long wear.
Should the tires become worn, there is an exchange policy where the wheels are returned for credit after the replacement
wheels are received. To remove a wheel, loosen both setscrews and pull straight out. If the wheel has bee I in place for a
long time, a wheel puller may be necessary. On replacement be sure to oil the shaft and hole to avoid rusting.
SPEED CONTROL; Variable speeds are selected through a column-mounted control wheel. An easy to change, easy to
set shift lever is mounted on the cross member near the table. In low range, speeds are from 47 to 470 SFM (14.33 to
143.3 mpm) and in high range, from 520 to 5200 SFM (158.5 to 1585mpm). A speed dial is mounted on the column of the
machine for' direct reading of surface feet per minute (meters per minute). If the shift lever will not go into the detent
position when changing range, rotate the lower wheel manually until teeth engage.
WHEEL BRUSHES: Check the wheel brushes occasionally. If they are worn so that they no longer con-tact the wheel
face, loosen the adjusting screws and move the brush up to the wheel. Replace as required.
TRANSMISSION: Drain, flush, and refill after first month and thereafter at least every six months.' Capacity is 3 quarts. Fill
to the top of fill pipe, but do not over fill. Check for seal leaks around the shafts. Any rough operation, vibration, loud or
unusual noises should be investigated immediately. It is recommended that the transmission be returned to the factory.
for repairs, or that repairs be made by a factory serviceman.
CAUTION: Difficulties in shifting may be caused by wear or incorrect adjustment in the shifting linkage and this
should be considered before repairing the transmission. It may be necessary to jog the band drive motor until
the shift lever is fully engaged, Do not attempt to force the shift lever into position. VARIABLE SPEED PULLEY:
Every six months remove the pulley unit, and wash and clean with solvent. Re-oil and install. Check the variable
pulley faces for scoring which could damage the belts.
BLADE INSTALLATION
NOTE:
If the blade width to be installed is less than ", use the 3/16" thick shim back of the upper
guide and turn the step in the bar support for the lower guide towards the trunnion. Check the inserts for the
correct width. The insert width should be slightly less than the distance from the back of the band to the bottom
of the gullet. Change them if required and leave them pulled away from the band. Lower the upper wheel
housing. Loosen both the insert clamp screws and remove the insert. Open booth doors and post-mounted
band guard. Loop the band over the upper wheel, feed it into the blade guard on the column and under the lower
wheel. Using the band tension handwheel, put tension on the blade. Rotate the wheels by hand and watch how
the band tracks on the wheels. Tilt the wheel if necessary to cause the band to run centered on the wheel. Check
to see if the blade is against the upper and lower guide backup bearing. For proper operation the blade should be
in firm contact with lower backup bearing and be in light contact or slightly clearing the upper backup bearing. If
it is not, see section on band saw alignment and realign the machine.
