The drive belt needs to be replaced as soon as it starts to
show signs of wear.
NeveR use a defective drive belt under
any circumstances. Indications of excessive belt wear are
fraying, squealing when in use, a belt that emit smoke or
a burning rubber smell when in use.
Under normal operating conditions, a drive belt may last
approximately 6 months. If your trowel is not reaching this
kind of life span for drive belt wear, check the drive belt for
proper pulley alignment and spacing.
