This section presents trouble-shooting guidelines for issues that may occasionally occur to a PowerFloat model. If you are experiencing issues with a PowerFloat that is not listed in the trouble-shooting guides below, then please contact the PowerFloat Office. Although most problems can be resolved personally by a PowerFloat owner, in some cases repair work will be required to return the PowerFloat to working order.
Select your problem
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 un-jam 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, then most likely tooth debris has become cemented in the gap created when the shaft is extended (pull out position) to rotate the shaft. To loosen, spray inside of the gap with WD-40, then lubricate with 3 in 1 oil. Forcibly loosen and resume using in both upper and lower position. This gap should be oiled bi-monthly to prevent build-up of debris.
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 unplugging the electrical cord and inverting the grinding head and pouring cold water on it with an injection syringe or a dose syringe. Resume use after cooling. Cool only by pouring or dripping water on inverted right angle. A wet towel application to the right angle may also be used.
DO NOT IMMERSE RIGHT ANGLE INTO WATER
ALWAYS UNPLUG POWERFLOAT BEFORE COOLING THE RIGHT ANGLE HOUSING
UNABLE TO GREASE ANGLE HEAD
Inability to grease probably means the grease fitting ball in the grease port has seized. Contact the PowerFloat Office to obtain a new fitting (grease port) with instructions for replacement.
DO NOT ATTEMPT TO DISLODGE GREASE NIPPLE
UNABLE TO REMOVE GRINDING WHEEL
If left over an extended period of time, the threads on the grinding wheel shaft that thread into the right angle may become cemented with tooth debris, thus making removal difficult. Obtain graphite (i.e. Liquid Wrench) from a local hardware store and lubricate underneath the wheel, enough to 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 vise-grip 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. Take the unit intact to an authorized drill motor repair shop for evaluation of the
motor brushes; or, contact PowerFloat Inc. or your regional distributor to arrange for repairs to the PowerFloat.
GRINDING WHEEL LOOSENS AND UNWINDS DURING OPERATION
If this occurs, the forward/reverse button on the DeWalt cordless has disengaged and is in the reverse position. The button on the right hand side of the gun should be pushed in flush to the housing and secured for normal operation. (The reverse switch on the plug-in model has been permanently removed).
