6. Retighten the cap screw on the slider block nut plate.
7. Slowly operate the back gauge the full length of travel. Verify that the back gauge does not bind or stall. Repeat the
slider block adjustment if necessary.
8. Reinstall the lower rear cover.
9. Reapply power to the cutter.
7.8 Back Gauge Calibration
The location of the back gauge is referenced from the “Home” position. “Home” position is determined during the homing
cycle when the homing flag (located on the back
gauge slider block, pg.28) enters and activates the homing sensor (mounted at the rear of the chassis). When this happens,
the read-out is reset to 26.000” on the Model 2650 and 21.000” on the Model 2150. If the back gauge is not at this distance
from the cut point (blade), all cuts made will be off the same amount. To calibrate the back gauge, proceed as follows:
1. Determine if the stock is being cut too short or too long. If the cut is too short, the
“Home” flag must be moved toward the cutting blade. If the cut is too long, the
“Home” flag must be moved away from the cutting blade. Determine the exact distance the cut is off. This is the dis-
tance the home flag will need to move.
2. Position the back gauge to approximately 20”.
3. Switch the ON/OFF toggle switch, located in the left switch panel, to the OFF position. Turn the key lock switch,
located in the right switch panel, to the OFF (Vertical) position.
4. Remove the lower rear cover. First remove the screws and nuts joining the lower
covers. Next remove the six screws that secure the cover to the chassis. Lower the rear cover and set it aside.
5. Mark the initial position of the “Home” flag on the side of the slider block for reference. Slightly loosen the two
screws that hold the “Home” flag to the slider block. Slide the “Home” flag the direction and distance determined in
step 1. Retighten the “Home” flag screws.
6. Switch the ON/OFF toggle switch to the ON position. Answer the prompts so that
the back gauge will go to the “Home” position.
7. Check the accuracy of the adjustment by cutting a sheet of paper and precisely
measuring the cut sheet. The cut length should be within .01” of the back gauge position (reading). If not repeat this
procedure starting with step 1.
NOTE: The back gauge must be “Homed” each time the “Home” flag is moved by turning the power
OFF and ON.
8. When the correct calibration is achieved, re-install the lower rear cover and return
the machine to operation.
7.9 Lubrication
The mechanical components of the cutter require periodic lubrication depending upon cutter use. A 30W oil, lithium-based
grease, and 90W gear oil are the recommended lubricants. Grease points should be cleaned and lightly recoated. Screws,
pivot points, and Oilite® bearings should be cleaned and lightly oiled. The gear box should be drained and refilled.
Heavy use is 8,000 or more cutting cycles per week. Moderate use is 4,000 - 8,000 cutting cycles per week.This schedule
is based on heavy use.
