The PowerFloat® has two grease fill ports. One located on the end of the grinding head (Fig.1 A); and the other located further along the shaft, situated beside the collar (Fig.2 D). USDA approved synthetic grease is required for smooth operation.

Grease should be applied after every 2 hours of operation.

1. To grease, rotate the shaft locking cover (Fig.2 C), until the shaft hole is uncovered (Fig.1 B).

2. The grease gun performs similar to a plunger. Insert the tip into the grease port and push down on the grease gun to force grease into the grease port (Fig.3).

3. Apply grease until a small amount of new grease (i.e. clean) is seen coming out of the shaft locking hole (Fig.3 E).

4. Two to four full pumps of grease into Grease Port (A) should be sufficient. The rule is to pump grease into Grease Port (A) until clean grease circulates through and exits from the shaft opening. The Grease Port usually requires two pumps from the grease plunger. Synthetic grease (USDA approved) can usually be purchased at local automotive retail stores.

CAUTION:
Do not apply grease into grease port unless the port opening is clean enough to see the silver check valve ball. Before applying the grease to the grease port, clean any debris from the opening. Do not insert a hypodermic needle or sharp object into the opening to clean debris. Only clean opening with with a wet, stiff bristled, nylon brush. Beneath the opening lies a small spring-loaded ball. Excessive pressure with any instrument may damage the mechanism. After physical removal of tooth debris from the port area, more cleaning may be done by spraying the area with WD-40™. Always lubricate grinding head before storing. Greasing before storage will aid in the prevention of corrosion of the internal gears and bearings.

Replacement tubes of grease are available through the PowerFloat Office. Please call toll-free within North American to place an order.

Available tube sizes are 12.5oz and 14.1oz.

All replacement grease tubes are Mobil brand synthetic grease.

To fill the grease gun with replacement grease:

1. Obtain an approved replacement canister of synthetic grease and insert the new canister into a lever-pump grease gun (example in Fig. 3).
2. Remove cap (A) (Fig. 1) from the PowerFloat grease gun.
3. Remove plastic piston (B) (Fig. 2) from inside the grease gun by pulling on the chain attached to the plastic piston.
4. Pump grease into the grease gun chamber until it is 85% full (Fig. 3).
5. Replace the plastic piston (B) (Fig. 2) and push inward to expel trapped air between the piston and grease.
6. Replace cap (A) (Fig. 1).
7. The grease gun is now (re)filled and ready for use.

In order to keep all PowerFloat models in good working condition, owners are advised to perform regular maintenance operations at specified intervals of operation. By performing regular maintenance operations, PowerFloat models can be kept clean, free of obstructing debris, and reduce the likelihood of repair work becoming necessary.

The following chart illustrates which maintenance to perform and at what intervals in the PowerFloat's operating life-cycle.

Clean and towel dry hands when doing dental procedures to keep motor housing clean. Periodically blow out all air passages with dry, compressed air. All plastic parts should be cleaned with a soft damp cloth.

DO NOT use solvents, soaps or other chemicals to clean plastic parts of the PowerFloat as they may damage such parts. The PowerFloat can be kept dry during storage by towel drying and wrapping it in a towel during storage.

CAUTION: Wear safety glasses while performing this operation.

Dry brushing of the grinding wheel can be accomplished by placing a soft steel or nylon brush on the wheel and spinning the wheel at 500 to 1000 rpms. After cleaning the grinding head and right angle, remove excess tooth material from the area with a dry towel. Do not immerse the grinding wheel and right angle into water. The grinding wheel can be cleaned with a wet brush by wetting and cleaning the brush in chlorhexidene and water. If using the electric plug in model adhere to electrical safety standards and clean the grinding wheel and right angle end with the Powerfloat unplugged from the electrical outlet.After cleaning always lubricate the right angle gear system before storing the PowerFloat. It is important to prevent corrosion of the gear system by keeping the gears well lubricated with a food grade anticorrosive lubricant.

CAUTION: Wear safety glasses while performing this operation.

(DO NOT IMMERSE THE RIGHT ANGLE GRINDING HEAD IN WATER)
