BELTS AND CHAINS
BRUSH DRIVE BELT
The two brush drive belts are located on the
cylindrical brush scrub head. The belts drive the
cylindrical brushes. Proper
new
belt tension is a 3
mm (0.1 in) deflection from a force of 1.37 to 1.48
kg (3.0 to 3.26 lb) at the belt midpoint.
When reusing an old belt, measure and record the
belt tension before removal, so that the belt can
be reinstalled at the same tension.
If the old belt tension was not recorded, the
recommended force per old belts is
1.03 to 1.14 kg (2.28 to 2.52 lb) with a deflection
of 3 mm (0.1 in).
Check the belt tension and wear every 100 hours
of operation.
STATIC DRAG CHAIN
A static drag chain prevents the buildup of static
electricity in the machine. The chain is attached to
the transaxle.
Make sure the chain is always touching the floor.
