BP-25H CE GASOLINE VIBRATOR — GENERAL INFORMATION
General Information
The BP-25H CE utilizes a 2.5 HP Honda GXH50 4-stroke,
overhead valve, single cylinder, gasoline engine. The vibrator
comes standard with a quick-disconnect coupling for easy
removal of the flexible shaft.
In addition, the frame is mounted on rubber isolators (3) to
help reduce engine vibration.
When operating the BP-25H CE Vibrator, always wear rubber
insulated gloves and boots. Safety glasses and ear protection
are also recommended.
Theory of Backpack Vibrator
The vibrator is designed for the
by removal of air pockets and voids.
The purpose of this vibrator is to set the particles in the
fresh concrete in motion, thereby reducing the friction and
giving the mixture a mobile quality so that gravity and the
displacement of entrapped air allows the concrete to settle
easily into place.
By consolidating the concrete quickly, "stiffer" or "drier" mixes
can be poured than would otherwise be possible.
Vibration also make the concrete more watertight, increasing
Tips
■
Keep the bending radius of the flexible hose to a minimum
during use.
■
Avoid starting the unit with the vibrator head immersed in
the concrete mix. After the engine has started, immerse
the vibrator head into concrete mix.
■
Excessive wear to the vibrating head can result from
resistance to weathering, and creating a better bond between
concrete and reinforcement.
Because vibration causes much of the entrapped air in the
concrete to rise to the surface, honeycombing is prevented.
Also, vibration eliminates most of the air pockets between
the concrete and the vertical forms.
misuse. DO NOT allow the head to vibrate against already
hardened concrete or steel used in reinforcement.

■
NEVER drop or knock the vibrator head against any
hard objects. This will prevent damage to the eccentric or
bearings contain within the head.
■
ALWAYS rinse or wipe off any wet concrete before it dries
or hardens on any part of the unit (engine, shaft, or head).

BP-25H CE GASOLINE VIBRATOR — HEAD AND SHAFT CONNECTIONS
Follow the instructions below when connecting the flexible shaft,
vibrator head, and vibrator, before using the BP-25H CE.
GREASING INSTRUCTIONS
1. Before installing a new flexshaft assembly, pull out the core
and lightly grease before first use. Place a handful of clean
grease (use Shell Durina EP2 high- temperature, highpressure grease or equivalent) in a shop cloth and slide the
clean core through grease as you feed it back into the shaft
housing.
2. After every job, or every 50 hours, the shaft should be
disassembled, cleaned, inspected, lubricated, and
reassembled.

Applying Loctite
When applying loctite to the flexible shaft casing threads, perform
the following:
1. Clean the mating connector or coupler threads with Loctite
Primer “T”.
2. Allow to dry several minutes before applying a ring of Loctite
No.271 to the middle of the flexible shaft casing threads.
3. Screw the head tightly to the flexible shaft casing and wait
for 1 hour before using. The threads are left hand, turn
counterclockwise to tighten. An equivalent brand of
anaerobic sealant may be used.
PAGE 16 — BP-25H CE GASOLINE VIBRATOR — OPERATION MANUAL — REV. #4 (12/19/07)
1. Remove motor from shaft.
2. Pull core from shaft housing. The head does not need to be
removed unless it also requires servicing.
3. As the core is removed, slide it through a clean shop cloth to
wipe off old grease. Keep it clean and off the ground or floor.
4. After inspecting the core for obvious damage, place a handful
of clean grease (use Shell Durina EP2 high- temperature,
high-pressure grease or equivalent) in a shop cloth and
slide the clean core through grease as you feed it back into
the shaft housing. This will lightly coat the core. Do not
overgrease. As the square end of the core approaches the
head, turn slightly to engage drive adapter inside the head
while continuing to push it towards the head.
5. Install motor to shaft assembly and securely tighten nut.
6. Test run the motor and check head vibration. Do not run
longer than one or two minutes when in the air (not in concrete
mix).

4. Immerse the head for 5 to 10 seconds, (until air stops
rising), and then withdraw it slowly to let the concrete fill
the void left by the vibrator head.
5. The vibrator head should be completely below the surface
when vibrating to keep the head cool.
6. Use the flexible shaft in as straight a position as possible
and DO NOT bend the flexible shaft sharply at any point.
Backpack Placement
Sharp bends may cause overheating, requiring early
replacement of the flexible shaft.
1. With the engine running at idle speed, place the backpack
on an elevated flat level surface (workbench or tailgate
of a truck). This will enable the operator to place the unit
