Note:
Make sure the drain valve is closed, the
canister door seal is clean and the door is
properly latched before operating the vacu-
um system. The system will not be able to
develop enough vacuum if the canister door
is not sealed and latched or the drain valve
is open.
It is normal for some water to travel to the vacuum
filter canister, therefore, it should be drained each
time the debris tank is drained or at least once
every 2 hours of operation. Remember that ex-
cessive water in the canister can pass through the
filter and cause severe damage to the blower. Al
-
ways make sure the PTO is disengaged to stop the
vacuum blower before draining the filter canister
and always close the drain valve when draining
is complete.
Vacuum Hoses
The primary vacuum hose runs from the cutoff
ball valve connection on top of the debris tank to
the vacuum hose connection on the vacuum filter
canister. Another debris suction vacuum hose runs
from the debris inlet elbow on the top of the debris
tank to the Hog Head. The hoses are equipped
with quick connectors at the Hog Head end that
allow additional vacuum hoses to be added or for
servicing Hog Head vacuum hoses and compo-
nents. Other quick connectors provide access to
service components of the vacuum system.
Consistent and proper vacuum is important to the
proper operation of the vacuum system. Debris
buildup, kinks, damage or leaks will cause a reduc-
tion in vacuum at the blasting head, reducing the
efficiency of operation or cause operations to stop
completely. 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
important to protect the hoses from contact with
sharp objects, abrasive surfaces, foot or wheel
traffic 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 by the high velocity of abrasive de-
bris traveling inside the hoses. The wear points
are most prevalent in the outside radius of tight
bends near the blast head and where the debris
hose rises above the truck cab. The life of the
hoses in these areas can be extended by rotating
the hoses 120
0
once each week.
Some types of debris will accumulate on the inside
walls of the hoses to the point where it restricts
debris flow in the system and reduces vacuum at
the blast head. 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 debris 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.
Blower And Silencer
The blower is powered by the auxiliary engine and
activated whenever the engine is running and the
PTO switch is on. It is driven by the PTO clutch
and a poly chain carbon belt. A overheat sensor
on the blower will disengage the drive pulley and
activate the fault light in the panel if the blower
overheats.
To avoid damaging the belt you must periodically
check the belt tension and adjust as necessary
using the adjusting bolts on the mounting base
of the blower. The tension specification for a new
belt is different than the tension specification of a
used belt with 20 hours or more of usage. Proper
belt tension is extremely important. Never over
tighten the belt. Drive belts are extremely strong
