SERVICE & MAINTENANCE
Check the condition of the drive belts annually or after
every 25 hours of operation, whichever comes first. also,
make sure the belt is tightened to the proper tension (1/4"
deflection). To adjust the belt:
Take off the belt guard by removing the 11/32” screws 1.
(figure 5.1).
loosen the three 1/4” carriage bolts attaching the
2.
transmission mount weldment (figure 5.2).
loosen the two 1/4" bolts that attach the 1/2”

transmission flange bearing.
with the five bolts loosened, slide the transmission
4.
mount weldment in the slotted holes to achieve proper
belt deflection. Belt deflection should be 1/4" when
pressure is applied to the belt half-way between the
two pulleys.
when proper belt tension is attained, retighten all 1/4"
5.
bolts to 9 ft-lbs.
Check for proper drive chain tension (1/4"

The vacuum debris bag requires an initial break-in period.
when using the bag for the first time, empty and wash
it frequently. The goal is to prevent dust from becoming
embedded in the bag. embedded dust will cause vacuum
performance to suffer. To remove the dust, empty the
debris and shake the bag vigorously. if needed, rinse the
bag with a hose. Thoroughly dry the bag before use.
