BP-25H CE GASOLINE VIBRATOR — OPERATION MANUAL— REV. #4 (12/19/07) — PAGE 11
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.
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
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 — GENERAL INFORMATION
Theory of Backpack Vibrator
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.
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.
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.
