CHAINS
WHEEL DRIVE CHAIN
The wheel drive chain is located between the front
wheels. The chain tension should be checked
after every 100 hours of machine operation.
The correct chain tension is 3 mm (0.12 in)
deflection from a force of 3.5 to 4.5 kg (8 to10 lb)
at the midpoint of the span of chain.
STATIC DRAG CHAIN
The static drag chain prevents the buildup of
static electricity in the machine. The chain is
attached to the underside of the machine between
the rear casters. Make sure the chain is making
contact with the floor at all times.
