MAINTENANCE
SERVICE AND ADJUSTMENTS
CHECK FOR LOOSE FASTENERS
• Before each use make a thorough visual check of
the spreader for any bolts and nuts which may have
loosened. Retighten any loose bolts and nuts.
CHECK FOR WORN OF DAMAGED PARTS
• Check for worn or damaged parts before each use.
Repair or replace parts if necessary.
CHECK TIRE INFLATION
• Checkiftiresareadequatelyinatedbeforeeachuse.
Donotinatetiresbeyondmaximumrecommended
pressure.
CAUTION: DO NOT inatetiresbeyondthe
maximum recommended pressure printed on
side of tire.
LUBRICATE (Seegure15)
• Lightly apply automotive grease as needed to the
sprocket and gear.
• Oil nylon bushings on vertical sprocket shaft and on
axle at least once a year, or more often as needed.
• Oil right hand (idler) wheel bearing at least once a
year or more often as needed.

CLEANING
• Rinse inside of hopper and exterior of spreader and
dry off before storing.
REPLACING SLOTTED GEAR
• If the axle, slotted gear and sprocket assembly is
disassembled, mark down the positions of the parts
as they are removed. The drive wheel and sprocket
positions in relation to the slotted gear determine
which direction the spreader plate will spin. Be sure
to reassemble them in their original positions. (Refer
togure3onpage4.)Useshimwashers(Ref.no.
21 on pages 10 and 11) as needed for minimum
backlash. Add grease to gear and sprocket.
LOCKED UP SPREADER
• Turn spreader over so that wheels are off the ground.
• Loosen all three nuts on the shaft support plate just
enough so that the bolts can be turned easily with a
wrench but cannot be turned by hand.
• Spin the drive wheel and note how freely it spins and
how much noise the slotted gear makes.
• To free up the wheel and gear, tap gently on the front
or rear edge of the shaft support plate to move it
slightly forward or backward. You can also tap at the
corners of the plate to angle it slightly.
• Spin the drive wheel after each adjustment to see if it
spins more freely and if the gear noise is reduced.
