BP-25H CE GASOLINEVIBRATOR — GENERAL INFORMATION  
General Information  
Theory of BackpackVibrator  
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.  
The vibrator is designed for the consolidation of concrete  
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.  
In addition, the frame is mounted on rubber isolators (3) to  
help reduce engine vibration.  
When operating the BP-25H CEVibrator, always wear rubber  
insulated gloves and boots. Safety glasses and ear protection  
are also recommended.  
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  
resistance to weathering, and creating a better bond between  
concrete and reinforcement.  
Tips  
Keep the bending radius of the flexible hose to a minimum  
during use.  
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.  
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  
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).  
Before operating this gasoline  
powered vibrator, the operator  
must read and understand the  
contents of the operation manual.  
Failure to read this manual could  
result in severe bodily harm and  
damage to the equipment.  
WARNING  
To avoid injury,  
you MUST read  
and understand  
operator’s manual  
before using this  
machine.  
This machine to  
be operated by  
qualified  
personnel only.  
Ask for training  
as needed.
