Gardner Bender BV208DA Blo-Vac - Manual (Page 10)

8.0 Maintenance
The Blowers and Blo-Vac™ systems should require very little
maintenance. If the unit should require service, see
instructions below.
Blower overheating occurs when attempting to blow line in
blocked conduit or a duct filled with water having a head
greater than the water lift capability of the blower. See 5.0
Technical Specifications, GB/JetLine
® Blowers Table.
The 1261 and B3000 Blowers have an automatic thermal
overload switch built into the motor. If overheating occurs, the
switch will turn the motor off. After a cool-down period of 15 to
30 minutes, the motor will automatically re-set. The motor can
be restarted.
Blo-Vac™ power units are equipped with a perforated filter
screen, located on the under side of the motor compartment.
Occasionally the screen becomes clogged with lint and dust
and it should be cleaned to maintain maximum air flow.
Vacuuming Dirt and Water — Each Blo-Vac™ comes with a
cloth filter bag that must be used when vacuuming dirt and
water. Use as follows:
1. Release the latches securing the top and center together.
2. Remove the filter bag from the bottom tool storage
section. Slide the filter bag onto the intake canister
located on the bottom of the motor. The filter bag
prevents dust from entering the motor. Dust and dirt will
damage the motor and cause premature failure.
3. After use, clean the filter bag by shaking off the excess
dirt and store the clean bag in the lower compartment.
4. The Blo-Vac™ is equipped with a ball float to prevent
water from entering the motor. If the ball float seals the
motor inlet, the motor will sound different from usual.
Immediately turn the unit off. Empty the recovery section
and check the inlet screen for lint and dirt. Clean and
reassemble the Blo-Vac™ sections.
