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 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 buildup 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 truck engine and
activated whenever the truck is in WORK mode
and the PTO switch is on. It is driven by the OMSI
PTO and a poly chain carbon belt. To avoid damag-
ing the belt you must periodically check the belt
tension and adjust as necessary using the adjust -
ing 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 and can
cause severe damage to the PTO, pulleys and
blower. Refer to the Maintenance section of this
manual for belt tension specifications and instruc -
tions for adjusting the drive belt.
The blower bearing housing is equipped with two
grease fittings that must be lubricated daily to
achieve maximum life expectancy. Refer to the
Lubrication & General Maintenance section of
this manual and the Blower operation manual for
lubrication specifications.
CAUTION
THE BLOWER BEARINGS MUST BE LUBRICATED DAILY WITH
THE GREASE SPECIFIED IN THE MAINTENANCE MATRIX AND
THE BLOWER MANUFACTURER. FAILURE TO LUBRICATE
THE BEARINGS DAILY OR USING GREASE OTHER THAN
THE GREASE SPECIFIED BY HOG TECHNOLOGIES AND
THE BLOWER MANUFACTURER WILL VOID THE WARRANTY.
Blower airflow is expelled through a silencer con -
nected to the outlet side of the blower. A flapper
installed on the silencer keeps water and debris
from entering the system damaging the blower
when the unit is shutdown.
