Maintenance (OlD Style clutch)
CHeCkINg THe DRIVe BeLT
The drive belt needs to be changed as soon as it begins
to show signs of wear. DO NOT reuse a belt under any
circumstances. Indications of excessive belt wear are
fraying, squealing when in use, belts that emit smoke or a
burning rubber smell when in use.
Under normal operating conditions, a drive belt may last
approximately 150 hours. 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 .
To gain access to the drive belt, remove the drive belt guard
cover, then visually inspect the drive belt for signs of
damage or excessive wear. If the drive belt is worn or
damaged, replace the drive belt.
RemOVINg THe DRIVe BeLT
„ Leave the existing drive belt intact until instructed to cut it.
„ Leave the engine in place for this procedure. It is not
necessary to slide the engine to replace the drive belt.
„ Have a 3/4 x 1 x 3-1/4 inch wooden block available.
