OPERATION
BRUSH PATTERN ADJUSTMENT
A properly leveled brush offers the best
sweeper performance.
1.
Move the sweeper to a dusty, flat surface.
2.
Set the prime mover’s parking brake.
Leave the engine running.
3.
Start the sweeper at a slow speed; then,
lower it completely to the surface so the
bristle tips touch the ground. Run the
sweeper in a stationary position for
10 seconds.
4.
Raise the sweeper and back away; switch
off the engine and remove the key. The
brush pattern left in the dust should be
2”-4” wide, running the length of the brush.
See Figure #1.
5.
If necessary, adjust the brush pattern with
the spring-chain assembly. See Figure #2
a.
Raise the sweeper.
b.
Tighten the transport chain (See
Figure #2) or lift cable and lower the
sweeper so it supports weight.
c.
Move the spring-chain forward in
the swing assembly chain holder to
lower the brush head assembly or
backward in the holder to raise it.
6.
Repeat steps 1-5 until the brush pattern is
2” - 4” wide
TRANSPORT CHAIN
NOTICE!
Units with a lift cable do not have a transport chain.
The transport chain supports the weight of the brush head assembly during transport
between work sites and during adjustment of the spring-chain assemblies. It should remain
slack during sweeping.
To adjust the transport chain:
1.
Raise the sweeper.
2.
Tighten the transport chain.
3.
Lower the sweeper so the transport chain supports the weight of the sweeper.
