GENERAL BTI compactors are designed to mount on mini-excavators, backhoes and excavators. BTI compactors combine impulse force, down pressure, and vibration to work as soil compactors or pile/sheet drivers. The compactor has 3 basic components: • Mounting Bracket: attaches the compactor to the carrier boom and is complete with adjustable mounting pins.
HAZARD ALERTS Danger, Warning, and Caution are hazard alerts used in this manual and on the compactor decals to identify hazards on or near the carrier and compactor. Danger - Immediate hazards, which WILL result in severe personal injury or death if the proper precautions are not taken. Warning - Hazards or unsafe practices, which COULD result in per- sonal injury or death if the proper precautions are not taken.

HAZARD ALERTS Do not operate the compactor with personnel in the immediate area of the carrier and compactor. Note and avoid all hazards and obstructions such as overhangs, ledges, slide areas, electrical lines, underground cables, water mains, gas lines, etc. When operating close to electrical lines, underground cables, water mains or gas lines, contact the responsible authority and request assis- tance.

HAZARD ALERTS Hydraulic fluids are under high pressure. Fluid escaping under pressure can penetrate the skin causing serious injury. Relieve all pressure before disconnecting hoses. Do not use your hand to check for hydraulic leaks. If any fluid is injected into the skin, a doctor must surgically remove it within a few hours or gangrene may set in.

HAZARD ALERTS Head Foot Protection Protection Do not operate or service the compactor unless you are qualified. Avoid loose fitting clothing, loose or uncovered long hair, jewelry and loose personal articles. These can get caught in moving parts. Jewelry may also ground a live circuit. Know and use the protective equipment that is to be worn when operat- ing or servicing the carrier.
The compactor must be sized properly for both the carrier on which it will be mounted and the work to be done. Sizing the Compactor based on the Type of Work Most applications require the soil under a road or load bearing surface to be compacted to 95% or greater than the density of the original material removed.
Page 16
SIZING THE COMPACTOR Always use a compactor sized to the carrier. A compactor that is too small for the carrier will damage the compactor, while a compactor too big will damage the carrier. Ensure you have the proper installation kit for attaching the compactor and that the carrier's hydraulic system meets the compactor flow and pressure requirements.
To run, a compactor needs hydraulic flow in one direction within a work- ing pressure range. When installing the compactor the carrier hydraulic circuit must have the following: • The carrier must have a hydraulic circuit which will provide the correct flow •...

TYPICAL HYDRAULIC CIRCUITS Carrier with Auxiliary Circuit Often a carrier is equipped with an auxiliary control valve (see Figure 1), this valve can be adjusted to provide the correct amount of oil flow to the compactor. A pressure relief cartridge can also be installed to protect the hydraulic components.
Page 19
Carrier without Auxiliary Circuit If the carrier does not have an auxiliary control valve (see Figure 2), a priority flow control valve must be installed to direct oil flow from the normal circuit to the compactor. The priority flow control valve is usual- ly equipped with a flow adjustment and pressure relief.
INSTALLATION There is no separate pressure adjustment on the compactor. The compactor's supply oil should be directed out the left side of the boom and the return line back on the boom's right side. A combination of hoses and steel tubing is recommended to keep the installation neat and cost effective.
START-UP Carrier oil should be clean and in accordance with the manufacturer's recommendations. After mounting the compactor on the boom and connecting the lines, bleed all air from the hydraulic system. Initially pump grease to the pins in the bracket until it oozes out around the pins.
OPERATION Compaction of Materials BTI compactors achieve material compaction by using impulse force and vibration to displace air and water pockets in the material. Compaction performance depends on 3 items: Use a short trial of the compactor to determine the optimum depth of lift and speed of boom travel to achieve the required density.
Page 25
Shut off the compactor and lift it into the air to a new position, or using minimum boom down-force slide the compactor along the ground. Avoid dragging the compactor's plate across the material surface ('ironing') while the motor is running. Forces exerted on the compactor by 'ironing' can cause premature failure.
Page 26
OPERATION When compaction is complete, shut off compactor before lifting it from Shut-off Compactor the ground. Before Lifting Do not pound the ground with the compactor. Do not start in the middle of an un-compacted area. Always start at the edge, near a solid wall, bank, or a previously compacted area.
Maintenance- Every 40 Hours of Operation Check hoses for wear and leaks, replace and tighten as required. The eccentric housing is filled with gear oil. This oil must be changed after the initial 50 hours. Then change oil every year. Use 80W90 gear oil.
