BELTS AND CHAINS
BRUSH DRIVE BELTS
The two brush drive belts are located on the
cylindrical brush scrub head. The belts drive the
cylindrical brushes. Proper belt tension is a 3 mm
(0.1 in) deflection from a force of 1.1 to 1.2 kg (2.5
to 2.7 lb) at the belt midpoint.
Check and adjust the belt tension every 100 hours
of operation.
STATIC DRAG CHAIN
The static drag chain prevents the buildup of
static electricity in the machine. The chain is
attached to the machine frame.
Make sure the chain is always touching the floor.
STEERING GEAR CHAIN
The steering gear chain is located directly above
the front tire.
The steering gear chain tension should be
checked after the first 50 hours of operation and
every 500 hours thereafter. The proper deflection
should be 3 to 6 mm (0.1 to 0.3 in) between the
steering sprocket and the idler sprocket when the
steering wheel is turned as far as it will go in
either direction.
