Vacuum Hoses & Tubes
The primary vacuum tube runs from the con-
nection on top of the debris tank to the cyclonic
separator, then to vacuum filter canister. Another
hose runs from the inlet elbow on the top of the
debris tank to the cutter shroud.
Consistent and proper air flow is important to the
proper operation of the recovery system. Debris
buildup, kinks, damage or leaks will cause a re-
duction in air flow at the cutter head.
Many problems with vacuum hoses are caused by
damage or kinks. You should avoid tight bends
and maximize the radius of all hose curves to
minimize the chance of a kink. It is very impor-
tant to protect the hoses from contact with sharp
objects or abrasive surfaces and to inspect the
hoses daily to ensure there is no damage, signs
of chaffing or kinks.
The inside walls of vacuum hoses develop wear
points caused from the high velocity of abrasive
debris. The wear points are most prevalent in the
outside radius of tight bends near the cutter where
the debris hose rises above the tank. The life of
the hoses can be extended by rotating the hoses

Vacuum Tube - Debris Tank to Cyclonic Separator
Vacuum Hose - Debris Tank to Cutter
Some types of debris will buildup on the inside
walls of the hoses to the point where it restricts
debris flow in the system and reduces vacuum at
the cutter. Debris buildup inside the hoses can
be removed by tapping the outside walls with a
dead blow hammer while the system is operating
at maximum vacuum. This will flex the hose walls
and cause the debris to break off and be sucked
into the tank.
Damaged vacuum hose can be repaired by cutting
out the damaged area and splicing in new hose.
Temporary repairs can be made using duct tape.
Cyclonic Separator
The cyclonic separator is mounted on the passen-
ger side of the chassis. Cyclonic action separates
debris and water vapor that may get past the de-
bris tank and drops it to the floor of the box at the
base of the separator. This reduces the amount
of debris and water reaching the filter canister,
increasing the time between filter cleaning inter -
vals and increasing the life of the filter element.
It is normal for some debris and water vapor to
travel from the debris tank to the cyclonic sepa-
rator box where it will accumulate. Excessive ac-
cumulation of water and debris in the cyclonic
separator will pass through the separator to the
