Belts
Inspect belts frequently for wear and serviceability. Replace a
belt that shows signs of severe cuts, tears, separation, weather
checking and cracking, or burns caused by slipping. Slight rav-
eling of belt covering does not indicate failure, trim ravelings
with a sharp knife.
Inspect the belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against the bot-
tom of the groove. Replace the pulley when this is the case, oth-
erwise belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or damage
the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt dress-
ings. Any of these will destroy the belt composition in a very
short time.
Deck Belt Adjustment
The spindle belt tension remains constant by means of a ten-
sion idler and spring. There is no tension adjustment of this belt.
