General Information
The
In addition, the frame is mounted on rubber isolators (3) to help reduce engine vibration.
When operating the
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).
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.
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.
