* Note:
Gearbox and lead screw lubrication
Lubricate the vise lead screw and gearbox with
Shell Valvata Oil No. J-78 or Macoma 72 or its
equivalent.
The gearbox gears run in an oil bath and will not
require lubricant change more than once a year
unless the lubricant is accidentally contaminated
or leakage occurs due to improper replacement
of the gearbox cover or gasket. During the first
few days of operation the drive gears will run
hot. Unless the temperature exceeds 200
degrees F., there is no cause for concern.
Blade tracking
1. If the blade is fully tensioned, release tension
slightly while performing the tracking operation.
2. If the blade is not on slow speed, change to
the slowest speed according to instructions in
Changing blade speeds .
3. Lift the saw arm to its full up position and
lock it using the hydraulic feed control knob.
Note: Use the handle on the arm to lift the
arm. Never use any other part of the arm as
a lifting method.
4. Remove the thumb screw and open the blade
guard cover. Prop it open so you can have
access to the idler wheel.
5. Refer to
Figure 11 . Use a wrench to loosen
bolt A , a small amount.
6. Turn the saw motor ON.
7. Insert a hex wrench into the set screw,
B ,
and turn it slightly while observing the tracking
action of the blade on the idler wheel. Turning
the hex wrench clockwise will make the blade
track toward the wheel flange. Turning the
wrench counterclockwise will make the blade track
away from the flange.
8. Adjust the set screw in
very small amounts until the
blade just starts to track toward the flange.
9. As you adjust the blade toward the flange, insert a
strip of paper between the blade and wheel as shown in
Figure 12 at the top of the next page.
CAUTION: Use a strip of paper six inches
long or longer so your hands stay clear of
the moving parts of the saw.
10. Keep using small amounts of adjustment to move
the blade toward the flange... testing with the paper
strips... until the paper is cut between the blade and
flange.
11. When the paper is cut, turn the hex wrench
slightly
in the opposite direction so the blade does not track
while touching the flange.
12. Tighten bolt
A .
13. Check with a paper strip to be certain the blade
has not moved back into contact with the flange.
Readjust, if necessary.
14. Using the blade tension knob, reapply tension to
the blade so it does not slip on the wheels.
15. Turn the saw OFF.
16. Close the blade guard cover and install and tighten
the thumb screw.
