MAINTENANCE INSTRUCTIONS
Inspect clean cutter saw before each use. Re-torque spindle bolts in an
alternating pattern to 204 ft-lbs. Check for loose, broken, chipped, dull or
missing teeth. Tighten all loose tooth assemblies by hammer and or replacing
rivets. If teeth tips are broken, chipped, or missing, replace tip or replace entire
tooth assembly. NEVER RUN SAW BLADE WITH MISSING TOOTH
ASSEMBLY. If saw blade is cracked, becomes bent or wobbles in excess of
two (2) inches while the tractor is idling, STOP, remove blade and have it
repaired at an approved service center. Call Tiger Service Department for
replacement parts and service.
These saw blades are pre-tensioned after the tooth assemblies are riveted
in place. This pre-tensioning ensures that the blade runs true and remains true
under normal cutting load. Removal of more than one or two complete tooth
assemblies at a time may effect the tensioning of the blade. Before cutting
always check for wobble while machine is running at idle. If blade wobbles in
excess of two (2) inches, STOP, remove blade and have it repaired at an
approved service center. The teeth tips can be replaced without removing the
tooth bodies from the saw blade (see TIP REPLACEMENT PROCEDURE).
This method is preferred over the entire removal of tooth assemblies.
Check adapter and collar every time saw is changed, maintain the .004 to
.006 inch taper (see figure below) on inside face (surface against saw blade) of
these two (2) items. Always clean inside face of adapter and collar before
mounting the blade. If adapter or collars are worn, chipped, or damaged, they
must be replaced.
Any saw blade (regardless of condition) that has seen regular use
should be serviced at least once a year at an approved service center.
Spare saw blades should be stored in a dry environment and transported
only on the wooden crates that are supplied with the saw blade.
