Drive Belt Replacement

Normal wear will require periodic belt tensioning and
replacement. Time of replacement will vary according to
usage and belt load factors.
Tools needed:
• 9/16" socket or wrench
• 1-1/8" open box wrench
• Straight edge or ruler
1. Wait until the FS351 cools off if it has been running.
2. Make sure the Removable Side Plate is installed.
This ensures the drive ends are in proper position for
servicing.

3. Clean the exterior of the machine so you can locate
all of the appropriate parts.
4. Using a 9/16" socket or wrench, remove the four hex
bolts attaching the belt cover to the side of the
machine. Remove the cover and set aside.
5. Turn the lower base plate pivot nuts clockwise with
the 1-1/8" wrench to lower the engine/motor base
plate. Use 9/16" wrench to lower the two bolts on
either side and loosen the drive belt. Remove or
replace the belt as needed.
6. To tension the belt, turn the base plate pivot nut with
the 1-1/8" wrench. This will raise the engine/motor base
plate. Use a 9/16" wrench to raise bolts into place,
locking jam nut when complete.
Ensure belts are aligned using straight edge or ruler
prior to operation. Do not over-tighten the belt as this
will cause premature wear to the belt.
