Checking the Hydraulic
Lines and Hoses
Service Interval: Before each use or daily
Check the hydraulic lines and hoses for leaks, kinked
lines, loose mounting supports, wear, loose fittings,
weather deterioration, and chemical deterioration.
Make all necessary repairs before operating.
Adjusting the Brush
The brush must make enough contact with conveyor
belt to disperse the topdressing material but not
restrict the rotation of the brush. You can insert a
piece of stiff paper between the conveyor belt and the
brush to check the adjustment. The brush must be
the same height from side to side. Check the brush
adjustment weekly for wear. The bristles of the brush
will wear under normal conditions and the distance
from the brush to conveyor belt should be maintained
to prevent uneven wear of the brush.
Note:
If using moist topdressing materials, you may
need to adjust the brush so that the bristles will whisk
material from between the conveyor belt lugs without
severely contacting the smooth portion of the belt.

If the adjustment is correct, tighten the nuts. If
not, repeat the procedure.
Adjusting the Drive Chain
Tension
Adjust the chain tension so that it deflects 3 mm (1/8
inch). Do not overtighten the chain; this will cause
chain wear. Do not operate with a loose chain, this
will cause sprocket wear.
Important:
The fasteners on the covers of this
machine are designed to remain on the cover
after removal. Loosen all of the fasteners on
each cover a few turns so that the cover is loose
but still attached, then go back and loosen them

until the cover comes free. This will prevent you
from accidentally stripping the bolts free of the
retainers.
