BP-25H GASOLINE VIBRATOR — SILICOSIS/RESPIRATORY WARNINGS

WARNING

SILICOSIS WARNING RESPIRATORY HAZARDS

Grinding/cutting/drilling of masonry, concrete, metaland other materials with silica in their composition may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis. In addition, California and some other authorities have listed respirable crystalline silica as a substance known to cause cancer. When cutting such materials, always follow the respiratory precautions mentioned above.

WARNING

Grinding/cutting/drilling of masonry, concrete, metaland other materials can generate dust, mists and fumes containing chemicals known to cause serious or fatal injury or illness, such as respiratory disease, cancer, birth defects or other reproductive harm. If you are unfamiliar with the risks associated with the particular process and/or material being cut or the composition of the tool being used, review the material safety data sheet and/or consult your employer, the material manufacturer/supplier, governmental agencies such as OSHA and NIOSH and other sources on hazardous materials. California and some other authorities, for instance, have published lists of substances known to cause cancer, reproductive toxicity, or other harmful effects.

Control dust, mist and fumes at the source where possible. In this regard use good work practices and follow the recommendations of the manufacturers or suppliers, OSHA/NIOSH, and occupational and trade associations. Water should be used for dust suppression when wet cutting is feasible. When the hazards from inhalation of dust, mists and fumes cannot be eliminated, the operator and any bystanders should always wear a respirator approved by NIOSH/MSHA for the materials beingused.

BP-25H GASOLINE VIBRATOR — GENERAL INFORMATION

General Information

The BP-25H 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 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).

Before operating this gasoline powered vibrator, the operator must

BP-25H GASOLINE VIBRATOR — HEAD AND SHAFT CONNECTIONS

Follow the instructions below when connecting the flexible shaft, vibrator head, and vibrator, before using the BP-25H.

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.

314V Series

Connecting the Flexible Shaft and Vibrating Head

Perform the following instructions to attach the flexible shaft to the vibrator, reference Figure 7:

Remove the female “Quick Disconnect” (Q.D.) coupler and

spindle shaft (female) from the parts bag. Note: The QD coupler and spindle shaft for the 314V Series are sold separately.

Screw the spindle shaft onto the male end of the flexible

shaft. Tighten securely. Screw the QD coupling onto the male end of the flexible

shaft. Tighten securely. Pull up on the Q.D. locking knob and insert the Q.D. coupler

into the eccentric end bell assembly.

382V Series

Connecting the Flexible Shaft and Vibrating Head

Perform the following instructions to attach the flexible shaft to the vibrator, reference Figure 7:

Remove the male “Quick Disconnect” (Q.D.) coupler and

spindle shaft (male) from the parts bag. Note: the QD coupler and spindle shaft for the 382V Series are included with the motor.

Screw the spindle shaft into the female end of the flexible

shaft. Tighten securely. Screw the QD coupling into the female end of the flexible

shaft. Tighten securely.

Pull up on the Q.D. locking knob and insert the Q.D. coupler into the eccentric end bell assembly.

Attach the vibrating head to the other end of the flexible

shaft. It is recommended the use of a small amount of pipe thread sealant (Loctite No.271) on the flexible shaft casing coupling threads to prevent water from entering the vibrator head.

Disassembly Instructions (use protective leather gloves)

When

rubber

vibrator heads are used, it is advised to place a protective sleeve over the flexible shaft casing coupler. This will protect epoxy coated rebar from being damaged. See proceeding pages in this manual for the

“Protective Sleeve”

installation instructions.

Attach the vibrating head to the other end of the flexible

shaft. It is recommended the use of a small amount of pipe thread sealant (Loctite No.271) on the flexible shaft casing coupling threads to prevent water from entering the vibrator head.

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.

PAGE 18 — BP-25H GASOLINE VIBRATOR — OPERATION MANUAL — REV. #7 (12/19/07)

1. Remove motor from shaft.

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).
