Operation - Greenlee 1399 Instruction Manual

Operation

1. Remove the safety hook from the shaft of the
handwheel. Raise the cutting head and lock it in
place.
2. Lift the vise ratchet dog and slide the movable vise
jaw so that the vise jaws will accommodate the item.
Place the material between the vise jaws and twist
the handwheel to clamp the material into place.
3. Loosen the wing screw and adjust the guide bracket
so that the adjustable roller support is as close as
possible to the item to be cut.
Important: The blade guide assembly must be at
least 5-3/4 inches from the tip-off block, or blade will
not be able to cut completely through the item.
4. Plug saw into an appropriate power supply.
5. Press start switch. Slowly lower the head until the
blade makes contact with the material. The saw will
shut off automatically.
6. When the cut is complete, raise the cutting head
and lock it in place. Open the vise and remove the
item.
Cutting Suggestions
• Select the proper blade and blade speed for the
material to be cut. See Blade Selection and Blade
Speed Chart.
• Set the blade at the proper tension.
• Reduce the feeding pressure for the first two or three
cuts with a new blade.
• Set the adjustable roller support so that it is as close
as possible to the item to be cut.
• Lower the cutting head slowly so that the blade will
begin cutting before the full amount of feed pressure
is applied to the blade.

Replacing the Saw Blade
1. Disconnect the saw from the power supply.
Note: If the band saw is equipped with a Wet Cutting
System, see the Exploded View—Switch and
Dash Pot Details (and optional Wet Cutting
System). Loosen two thumb screws (15) and
remove the chip pan and splash guard assembly
(1 & 2). Proceed to Step 2.
2. Remove the safety hook from the shaft of the
handwheel. Raise the cutting head to the vertical
position.
3. See the Exploded View—Blade Guides and Gear
Box Details. Loosen the wing nut (48). Remove the
blade guard (25).
4. See the Exploded View—Wheel and Frame Details.
Loosen the thumb screw (33) on the idler wheel
guard (31). Open the guard. Loosen wing nuts (27)
and remove the drive wheel guard (37).
5. Twist the wing screw (10) to release blade tension.
6. Uncoil a new 1/2" x 93" blade. Viewing the saw from
the operator's side, the teeth must point toward the
motor end. If the teeth do not point in this direction,
turn the blade inside out.
7. Install the blade:
a. Place the blade between the blade guide ball
bearings and brushes.
b. Slide the blade onto the drive and idler wheels.
c. Twist the take-up screw until the blade is taut.
When pressed, the blade should have approxi-
mately 1/4" of play.
8. Replace the blade guards and lower the cutting
head. Connect the saw to the power supply. Start
and stop the saw a few times.
9. Raise the cutting head to the vertical position and
check the blade to see that it is riding correctly
on the idler wheels. The blade should be within
approximately .032" from the flange of the idler
wheel. If it does not, see Wheel Pitch Adjustment in
the Maintenance section of this manual.
