LUBRICATION

The PowerFloat should be greased after each 5 dental procedures.

Clean the grease port with a brush to remove all debris in the port. Attach the needle point adapter on the grease gun to the grease port. Rotate the black steel shaft cover to expose the shaft openings and slowly pump until fresh grease begins to exit from the openings. The grease port contains a spring-loaded ball and is designed to accept grease slowly. If the grease gun is warm, the grease will flow more easily. Replace the black steel cover. Clean and lubricate the entire instrument before replacing it in its case. Keep a dry towel in the carrying case to absorb moisture.

The grinding wheel of the PowerFloat is driven by a gear and spline system made of a metal alloy. The gears should be protected with adequate lubrication. Water and saliva can have a negative effect when it gains entry into the gear mechanism. Lubricate the PowerFloat to protect your investment.

Please DO NOT dunk your PowerFloat in water.

General Troubleshooting

STAINLESS STEEL GUARD TURNING

The guard should fit tightly and not turn during grinding procedures. To tighten guard, place a nail in the shaft opening to lock the shaft and remove grinding wheel with pliers by turning wheel counter clockwise. Tighten the flat nut located on top of the stainless steel guard located under the grinding wheel with a Husky brand flare nut wrench - 17 mm metric, or with a suitable Vise-Grip. Turn the nut counter-clockwise to tighten.

GRINDING WHEEL IS NOT TURNING

Most likely, the mesh of the gears under the grinding wheel have jammed. The clutch prevents the shaft from turning the gears when you start the unit. Simply apply pliers to the top of the grinding wheel and forcibly turn the wheel clockwise or counter clockwise to unjam the gears. Then press the trigger on the motor to begin operation.

SEIZED COLLAR ROTATIONAL SYSTEM

If the instrument head cannot be rotated to an up or down position:

Over time, tooth debris can become cemented in the gap created when the shaft is extended (pull out position) to rotate the shaft. This gap should be oiled bi-monthly to prevent build-up of debris. To loosen, spray inside of the gap with WD40, then lubricate with 3 in 1 oil. Forceably loosen and resume using in both upper and lower position.

ANGLE HEAD HEATS UP EXCESSIVELY

The right angle housing contains gears and bearings that generate heat at high RPM's. Continuous use of the PowerFloat at maximum RPM's is NOT recommended. To prevent overheating and injury to the horses soft tissue, the operator can periodically cool the housing by inverting the grinding head and pouring cold water on it with an injection syringe or a dose syringe. Resume after cooling. Cool only by pouring or dripping water on inverted right angle. DO NOT IMMERSE RIGHT ANGLE INTO WATER.

UNABLE TO REMOVE GRINDING WHEEL

If left over an extended period of time, the threads on the grinding wheel shaft that screw into the right angle may become coated with debris causing seizing thus making removal difficult. Obtain graphite (Liquid Wrench) from local hardware store and lubricate under the wheel sufficiently so it will penetrate the threads. Let sit for 10 minutes and then re-attempt to loosen wheel by turning in a counter clockwise direction using a pair of pliers. Repeat procedure until successful. Apply grease to the threads on the new grinding wheel before replacement.

MOTOR LOSING POWER

The motor brushes may be worn. Please send PowerFloat to EVDS Dental Instruments with completed PowerFloat Repair Forms A and Service Form B and send registered mail to:

GRINDING WHEEL LOOSENS & UNWINDS DURING OPERATION

If this occurs, the forward/reverse button on the Porte Cable gun has disengaged and is in the reverse position. The button on the right hand of the gun should be pushed in flush to the housing and secured for normal operation.
