HTN-SERIES — MAINTENANCE
Checking The Drive Belt
The drive belt needs to be replaced as soon as it starts to show
signs of wear. 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 (item 1 Figure 17), 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.
DO NOT
remove the drive belt guard cover
until the muffler has cooled. Allow the entire
trowel to cool down before performing this
procedure.
DO NOT
attempt to insert hands or tools
into the belt area while the engine is
running.
NEVER
run the engine with the
safety guards removed. Keep fingers,
hands, hair and clothing away from all
moving parts to prevent bodily injury.
