WARNING! BEFORE PERFORMING MAINTENANCE OR SERVICE LOWER THE ATTACHMENT
TO THE GROUND, DISENGAGE AUXILIARY HYDRAULICS, TURN OFF THE
ENGINE, REMOVE THE KEY AND APPLY THE BRAKES.
WARNING! NEVER PERFORM ANY WORK ON THIS ATTACHMENT UNLESS YOU ARE
AUTHORIZED AND QUALIFIED TO DO SO. ALWAYS READY THE OPERATOR’S
MANUALS BEFORE ANY REPAIR IS MADE. AFTER COMPLETING
MAINTENANCE OR SERVICE, CHECK FOR CORRECT FUNCTIONING OF THE
ATTACHMENT. IF NOT FUNCTIONING PROPERLY, ALWAYS TAG “DO NOT
OPERATE” UNTIL ALL PROBLEMS ARE CORRECTED.
REPLACING TEETH
Worn, broken or missing teeth will cause excessive machine vibration and reduce productivity. It is
important that all teeth are attached properly. Double sided, reversible teeth can be rotated when
worn or if carbide points are broken or missing.
1. Remove existing tooth.
2. Check to make sure the mounting surface and bolt holes are clean and free of debris. Any
accumulation of debris can cause the tooth not to seat properly in the slot resulting in unsafe
operation.
3. Position the new tooth onto the holder and after both bolts have been started, push the tooth up
into the mounting slot and tighten with an impact wrench. Torque to 150 ft.lbs.
NOTE: Replace any damaged bolts. Always replace lock washers when installing a new tooth. Install
washers with the side that is higher in the center towards the bolt head.
NOTICE: Failure to start both bolts into the tooth first before tightening a bolt, can bind the other bolt,
and damage the bolt and possibly the cutting tooth, rendering the tooth and bolt unusable.
WARNING! IMPROPER MOUNTING CAN VOID WARRANTY AND CAUSE SERIOUS
INJURY AND/OR DEATH. USE ONLY MANUFACTURER REPLACEMENT
PARTS.
DRIVE BELT TENSIONING AND/OR REMOVAL
Due to thermal expansion of the sprockets during operation the belt tension will vary between a cold
unit and one that has just been in operation. We recommend checking tension after operation when
the belt and sprockets are still warm. Although there are various ways of checking belt tension we
recommend using a single barrel (pencil type) belt tension tester which can be purchased locally.
CAUTION! DUE TO THE HOT TEMPERATURES OF THE COMPONENTS WHEN CHECKING
THE BELT TENSION ON A MULCHER THAT HAS BEEN IN OPERATION, GLOVES
ARE REQUIRED TO PREVENT PERSONAL INJURY.
CHECKING BELT TENSION
1. Remove the belt tension access cover from the top of the drive housing or the drive belt cover
from the side of the drive housing to check belt tension. Depending on the type of tension tester
being used. See tension chart.
2. If using a pencil type tension tester, insert through hole in top of drive housing compartment and
check belt tension. Check belt tension half way between the two sprockets and in the center of
the belt. See tension chart.
