Blade Instructions (cont.)
Replacing Bandsaw Blade
Ensure the proper protective gear is being worn (gloves, safety glasses, etc.)
when changing the blade.
1. Open the bandwheel covers and open the rear blade cover.
2. Cut old blade and remove from SpeedCut.
3. Carefully unwind the new blade with the assistance of a second person.
4. Insert new blade by lowering over the Clamping System (optional) and setting in place.
Ensure the new blade is properly aligned inside the blade guides with the blade teeth pointing
down and toward the driving bandwheel.
5. Push the blade snugly up against the flange of each bandwheel using spring clamps to
temporarily hold blade in place.
6. Slowly tighten the blade tension nut using the torque wrench provided. Continue to monitor
the blade position so that the blade remains snug against the flange of each bandwheel.
7. Continue to tighten the nut and watch the dial on the torque wrench. The blade is properly
tensioned when the torque on the nut reaches 484 kg/cm (35 lb/ft).
NOTE:
Do NOT over tension. Use of a “click type” torque wrench is not recommended.
8. Remove the spring clamps, close the bandwheel covers and the rear blade cover.
Blade Guides
The blade guides are arranged to hold the blade in alignment both vertically
and horizontally. Before making adjustments, always try a new blade to be
sure that the old blade was not causing the difficulty.
Blade Brushes
Brushes should be cleaned frequently in kerosene and reversed to take
advantage of both rows of bristles. For best results, replace worn, filled
or sticky brushes with new ones. In bolting brushes to angles, be sure
wire bristles are bent in the same direction as the blade travels.
Blade Break/Stall Proximity Switch
This saw is equipped with a Blade Break/Stall Proximity Switch. Should the
blade break or stall in the work, the blade motor will stop if the saw ceases
operation. This allows the operator to leave the machine unattended with
greater confidence. The operation of this feature is fully automatic and
requires no attention. The sensor is located under the Idle Bandwheel
and monitors the spokes as they pass over the sensor.
Saw Frame Rests/Stops
At the bottom of the stroke the saw frame rests on two removable stops.
Should the saw frame need to be lowered below the base position, these
stops can be temporarily removed.
Belt
Proper adjustment of the ‘V’ belt is important to prevent overheating
of the motor. Be sure the belt guard is closed after changing blade speeds.
