HM126 Operator’s Manual
TEST PROCEDURE
1. Always wear safety gloves and eyewear. Never attempt to adjust the blade tracking with
the engine running. Remove the spark plug cap as a safety precaution.
2. Loosen the blade guide assemblies, push them back as far as possible, and secure.
This will ensure the guide blocks and bearings will not touch the blade during the test.
3. Install a blade if one is not already installed.
4. Fully tension the blade to 25 ft•lb using a torque wrench—or—snug the tension handle to
the thrust bearing and then rotate it a further three (3) full turns.
5. Start rotating the band wheels by hand in the direction of cut observing how the blade
moves
forward
or
rearward
on the belts to find its “hold” position.
**If the blade looks as if it is going to come off during hand rotations—STOP—and
or
as required.**
Important Points Before Making Adjustments
:
‣
Start adjusting the side that is furthest out of spec first.
‣
Since adjustments made to one side can affect the other side, always adjust one side
first, rerun this test procedure, then adjust the other side if needed.
‣
Because
¼
turn adjustment increments are recommended, it is common to run this test a
few times between multiple adjustments before correct tracking is achieved.
