Vacuum Blower System: 8-2
To protect the vacuum blower from overloading and damaging itself, there is
a vacuum relief system installed on the vacuum recovery tank. When the
recovery tank inlet is completely sealed o, a maximum of 14” Hg will be
attained. At the end of each day, spray the HydraMaster-recommended lubricant
(P/N 000-087-006) into the blower lubrication port before shutting down the
machine. If you fail to lubricate the vacuum blower on a daily basis, rust deposits
and moisture can form and decrease the life of the vacuum blower.
Foam passing through the blower could lead to serious problems. Therefore, it
is important to keep the recovery tank foam free. When cleaning surfaces with
excessive foaming residue, use HydraMaster’s Defoamer as directed.
The recovery tank is protected from excessive water level overowing by a
recovery tank oat kill switch. The switch is not activated by foam, only by liquid.
RECOVERY TANK INLET FILTER
HydraMaster inlet lter screens are designed to trap lint, hair and large objects that would
normally collect at the bottom of your recovery tank. Clean the screen at the end of each
job to eliminate build-up of debris in the tank.
VACUUM BLOWER LUBRICATION
Read the vacuum blower Owner’s Manual for proper oil changing instructions. (A digital
copy of the vacuum blower Owner’s Manual can be found on the CD which is shipped
with each CDS 4.8 Owner’s Guide.) Because the CDS is very demanding of the vacuum
blower, the vacuum blower should be maintained as recommended in the vacuum blower
Owner’s Manual.
The vacuum blower manufacturer recommends the use of PneuLube™ (ISO
100) as a lubricant at temperatures ranging from 0 degrees to 120 degrees F.
