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.

manual for instructi
Figure 4. Honda GXH50 Engine Components  
1. Choke Lever – Used in the starting of a cold engine, or  
in cold weather conditions. The choke enriches the fuel  
mixture.  
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.  
2. Spark Plug – Provides spark to the ignition system.

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.  
CAUTION - READ MANUAL  
DO NOT attempt to operate the  
vibrator until the Safety, General  
Information and Inspection sections  
of this manual have been read  
thoroughly and understood.  
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.  
Sharp bends may cause overheating, requiring early  
replacement of the flexible shaft.  
Backpack Placement  
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  
on his back more easily.  
CAUTION - SHAFT OVERLOAD HAZARD  
If the shaft begins to helix (buckle) excessively during  
operation, stop and investigate.This is an indication of an  
overload condition.  
2. The backpack unit attaches very much like a hiker’s  
knapsack. Place your arms through the spaces between  
the shoulder straps and the frame.  
3. Next, bring the abdominal straps to the front and adjust  
the straps accordingly. There are two sets of velcro  
straps, one set for the chest an another for the waist  
area.  
CAUTION -VIBRATOR HEAD OVERHEATING  
The vibrator head is cooled by the concrete.  
Operation of the vibrator head in air longer than 2  
minutes will cause overheating of the bearings which  
result in premature head failure.  
Operation  
1. Insert the vibrator head into the concrete.  
2. Turn the throttle grip (Figure 16) CW to the “RABBIT”  
(fast) position for normal operation.
