Blade Tracking Adjustment
Since tracking can only be adjusted while
machine is running, it is suggested that this
adjustment be accomplished by qualified
personnel that are familiar with this type of
adjustment and the dangers associated with it.
Blade tracking has been set at the factory and
should require no adjustment. If a tracking
problem occurs, adjust the machine as follows:

WARNING
Tracking adjustment is done with the wheel
covers open to observe the blade. Use
extreme caution so as not to come into
contact with the blade!
1. Raise saw arm to its highest position.
2. Locate tracking adjustment plate on the
backside of the idle wheel.
3. Loosen the three bolts (A, Fig. 12) located
on the top of the tracking nuts.
4. Tracking adjustment is accomplished by
either loosening or tightening three adjusting
nuts (B, Fig. 12).
5. Tracking is set properly when the back of
the blade lightly touches the wheel flange.
Note: over-tracking (allowing blade back to
rub hard against wheel flange) will damage
the blade wheels and blade.
6. Tighten locking bolts (A) once proper
tracking is completed.
Lubrication and Gearbox
All ball bearings are permanently lubricated and
sealed. They require no further lubrication.
The gearbox lubricant should be changed after
the first 3 months of operation. Use Mobil SHC
634, or equivalent. Change lubricant from then
on every year.
To check level of gear box lubricant, place arm
in down position and allow a few minutes to
pass so that oil drains down. Check level in
sight glass on side of gear casing. Correct level
is the dot in the middle of sight glass.
