BLADE INSTALLATION
NOTES ABOUT NEW BLADES:
•
It is helpful to have two people to install a new blade.
•
A new blade will come folded into a compact coil. Follow the blade manufacturer’s instructions for safely unfolding
blade.
•
The blade must be installed with the teeth facing out towards the front of the saw where it passes around the
wheels, and with the teeth in the cutting area pointing towards the drive wheel. This may require that the blade be
turned inside out before installation.
1. With the Blade Change Mode key switch remaining in the ‘ON’ position, turn the Blade Tension Switch to the
LOOSEN position for several seconds until the idler wheel has fully retracted.
2. Insert new blade into the blade guides and briefly onto the wheel.
3. Turn the Blade Tension Switch briefly to TIGHTEN “+/RUN” and then leave it in HOLD, to retain the blade lightly
on the wheels.
4. Adjust blade position on the wheels so that the blade is not crooked on them and the teeth overhang the front
edge of the wheels.
5. Turn the Blade Tension Switch to TIGHTEN “+/RUN”.
6. Close both blade wheel doors.
7. Turn the Blade Change Mode key switch to the ‘OFF’ position. Hydraulics will shut down.
8. Switch the hydraulics ON, start the blade and run for 20 seconds.
9. STOP the blade.
10. Turn the blade change key switch to the ‘ON’ position.
11. Open the blade wheel doors and inspect the blade tracking, plus the position of the blade brush. Refer to
following pages for tracking adjustments, if necessary.
12. Close the carbide locks, blade guard, and the blade wheel doors. Turn the Blade Change Mode key switch to the
‘OFF ‘ position.
13. Blade change procedure is complete.
BLADE TRACKING
First, inspect the blade wheels for wear or damage and repair as required. Blade tracking adjustment should always begin
at the wheel where the tracking is farthest out of specification. Using the instructions below, adjust the worst wheel, jog
the blade and check both wheels. Repeat this process until both wheels are within specification (.200-220” of tooth over
hang from the front of the wheel). Both the drive and idler wheels are factory set a certain distance from the wall behind
the wheel. Adjustment should not be required unless the wheel is being replaced. On the drive wheel there is a large hex
head bolt and four set screws in a “push/pull” arrangement. For the idler wheel there is single adjuster assembly in the
centre of the idler shaft under the cover on the front of the head. Hyd·Mech Service should be contacted before making
any adjustment to the wheel position.
DRIVE WHEEL ADJUSTMENT
Adjustments should be made with the blade tension released slightly.
The drive wheel has two mounting bolts and two adjusting bolt as-
semblies. The mounting bolts (A) should be loosened but remain
snug before making any adjustment to the bolt assemblies (B & C).
Both of the bolt assemblies should be adjusted by equal amounts.
To adjust the bolt assemblies, release blade tension slightly, loosen
bolts “B” and turn bolts “C” in or out by equal amounts and tighten
bolts “B”. Turning bolts “C” out will pull the blade onto the wheel and
turning them in will push the blade off the wheel. Check the track
-
ing movement after each one quarter turn of bolts “C” by running the
blade at minimum speed. When the tracking is within specification,
tighten bolts “A”.
