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).

8.Fuel Tank/Fuel Filler Cap – Fuel tanks holds 0.32
gallons (1.2 liters) of unleaded gasoline. Remove fuel
filler cap to add unleaded gasoline to the fuel tank. Make
sure cap is tightened securely. DO NOT over fill.
Adding fuel to the tank should be done
only when the engine is stopped and has
had an opportunity to cool down. In the
event of a fuel spill DO NOT attempt to
start the engine until the fuel residue has
been completely wiped up, and the area
surrounding the engine is dry.

Before starting and operating the BP-25H CE Gasoline
Vibrator, perform the following:
■
Read safety instructions at the beginning of the manual.
■
Clean the engine, removing dirt and dust, particularly
the engine cooling air inlet, carburetor and air cleaner.
■
Check the air filter for dirt and dust. If air filter is dirty,
replace air filter with a new one as required.
■
Check carburetor for external dirt and dust. Clean with
dry compressed air.
■
Check fastening nuts and bolts for tightness.
■
Check the engine oil level.
■
Check the fuel level.
■
Check the tension and condition of the V-belt.
Fuel Check
1.Remove the gasoline cap located on top of fuel tank.
2.Visually inspect to see if fuel level is low. If fuel is low,
replenish with unleaded fuel.
3.When refueling, be sure to use a strainer for filtration. DO
NOT top-off fuel. Wipe up any spilled fuel.
Engine Oil Check
1.To check the engine oil level, place the backpack frame

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.
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).

DANGER - EXPLOSIVE FUEL HAZARD
DO NOT use gasoline as a cleaning solvent
to avoid creating the risk of fire or an
explosion.
V-Belt Tension
The V-belt (Figure 25) can be adjusted by loosening the
bearing block housing screws, and rotating the eccentric
end bell housing until the desired tension is achieved.
When the V-belt is properly tensioned, it should deflect
approximately 5 to 10 mm when 5-10 pounds of force is
applied centrally between the pulleys. Lock the
countershaft in place with the locking screw and wing
nut.
Quick Disconnect Lock
A small amount of any lightweight oil should be used on the
locking mechanism (Figure 26) to help keep concrete from
sticking and also to lubricate the locking pin and spring.

BP-25H CE GAS VIBRATOR — PREPARATION FOR LONG -TERM STORAGE
For storage of the vibrator for over 30 days, the following is
required:
■
Drain the fuel tank completely, or add STA-BIL to the fuel.
■
Run the engine until the gasoline in the carburetor is
completely consumed.
■
Completely drain the oil from the crankcase and refill with
fresh oil.
■
Remove the spark plug, pour 2 or 3 cc of SAE 30 oil into the
cylinder and crank slowly to distribute the oil.
■
Slowly rotate the engine a few times with the starter rope and
install a new plug.
■
Pull out the starter rope slowly and stop at the compression
point.
■
Clean all external parts of the engine and frame with a soft
cloth.
■
Cover the unit and store in a clean, dry place.
Decommissioning Vibrator/Components
Decommissioning is a controlled process used to safely retire
a piece of equipment that is no longer serviceable. If the
equipment poses an unacceptable and unrepairable safety
risk due to wear or damage or is no longer cost effective to
maintain (beyond life-cycle reliability), and is to be
decommissioned (demolition and dismantlement), the
following procedure must take place:
■
Drain all fluids completely. These may include oil, gasoline,
hydraulic oil and antifreeze. Dispose of properly in accordance
with local and governmental regulations. Never pour on ground
or dump down drains or sewers.
■
Drain excess gasoline from the fuel system into an approved
storage container.
■
Engine block is made of recyclable aluminum. Plastic engine
components should be removed and recycled separately.
■
The frame and control arm are manufactured of recyclable
steel. Bring to a salvage yard or metal reclamation facility for
further dismantling.
■
The harness assembly is made of non-recyclable fabric.
