MAINTENANCE PROCEDURES
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 thedrive belt is worn or damaged, replace the
drive belt.
