MAINTENANCE
BLADES
Check the Blade for cracks and wear and Blade Bolts for tightness, daily. Blades should be replaced when they
are worn excessively, bent, deformed, or out of balance.
Blades should always be replaced in pairs. Blades of different weights can cause serious
imbalance and damage to the machine and personnel. When replacing blades, take care to
replace the bolts, nuts and washers.
HARDWARE
Most nuts and bolts will stay tight and therefore need only periodic checking. However, the following nuts and
bolts are extremely important and should receive special attention:
Spindle Housing Bolts: Tighten to 240 ft./lbs. Torque
Blade Bolts: Tighten to 300 ft./lbs. Torque
Blade Carrier Hub Bolts: Tighten to 450 ft./lbs. Torque
BLADE SERVICING
Inspect blades before each use to determine that they are properly installed and in good condition. Replace
any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out
when sharpening.
When sharpening blades, grind each blade the same amount to maintain balance. The
difference in blade weights should not exceed 1 ounce. Unbalanced blades will cause
excessive vibration which can damage gear box bearings. Vibration may also cause
structural cracks in cutter housing.
Use only original equipment blades on this cutter. They are made of special heat-treated
alloy steel. Substitute blades may not meet specifications and may fail in a hazardous
manner that could cause injury.
When changing Blades always replace the Blade Bolt & Blade Nut at the same time.
Reused Blade Bolts or Nuts could fail in a hazardous manner that could cause injury.
Inspect Blades daily for normal wear. If Blades have a notch worn into the leading worn into
the leading edge at the lower bend more htan 1/2” DEEP (due to running in gravel and/or
the ground), REPLACE BOTH BLADES ON THAT CARRIER IMMEDIATELY. Failure to
replace such abnormally worn blades may lead to catastrophic failure of the blade and
ejection of the broken part with tremendous force which may cause bodily injury or death.
NOTE: Replace Blades in pairs after no more than 1/2” notch wear.
