Troubleshooting

ELECTRIC MOTOR.

Application: 8FP/E Series Floor Planer.

MOTOR FAILS TO START

ON/OFF switch in the OFF position. Turn the switch to the ON position.

Improper voltage selection. Determine the available voltage value from the power source. Move the voltage selection switch located on the motor to the proper selection.

Floor Planer and/or extension cord is not plugged into the power source. Determine that all electrical connections have been properly made. The NEMA 6-

20Series cap and receptacle set is of a twist lock configuration and requires a twist motion to ensure a proper connection.

Improper extension cord size and capacity. Operate the Floor Planer with copper stranded, 8 AWG or larger extension cords. Improper extension cord size and capacity will result in significant heat rise and corresponding voltage and amperage drop.

Thermal protection device activated. To protect the motor against heat related damage, an automatic thermal protection switch is provided near the voltage selection switch. High operating temperatures will activate the switch and shut the motor off. After the motor has cooled to an acceptable temperature level, depress the switch to restart.

MOTOR LOSES POWER

Improper extension cord size and capacity. Replace with cords meeting the required specifications.

Excessive extension cord length. Even with proper extension cord size and capacity, excessive cord length can reduce the available voltage and amperage to the motor. Measure the Available voltage to the motor where the extension cord connects to the Floor Planer with a voltmeter. Reduce the extension cord length as required to achieve the minimum voltage operating specification as required by the motor manufacturer.

Insufficient available voltage and amperage at the power source. Measure the available voltage at the power source (usually a receptacle) with a voltmeter. If the available voltage is below the minimum operating specification as required by the motor manufacturer, utilize an alternative power source.

Improper motor cooling. See ELECTRIC MOTOR SERVICE.

Excessive load to the motor. See OPERATING THE FLOOR PLANER ON THE JOBSITE.

ENGINE.

Application: 8FP/G Series Floor Planer.

ENGINE FAILS TO START

Ignition switch in OFF or cut off position. Place switch in the ON position or move throttle control lever to the ignition operational position.

Incorrect carburetor/fuel injection system adjustment. See SERVICE section.

Air filter blocked. See SERVICE section.

Ignition wire to spark plug loose or disconnected. Re- connect.

Fuel supply exhausted. Refill the fuel tank.

ENGINE LOSES POWER

Incorrect carburetor/fuel injection adjustment. See SERVICE section.

Water in fuel supply. Drain and replace fuel.

Excessive carbon accumulation in combustion chamber. See SERVICE section.

Fuel tank breather vent closed (if so equipped). Open vent.

Air filter blocked. See SERVICE section.

OPERATIONAL PROBLEMS.

Application: All Models.

UNEVEN FLAIL WEAR

Excessive cutting depth for the feed/travel rate. Raise the flail drum and make multiple, shallow passes instead. Reduce the feed/travel rate. See

OPERATING THE FLOOR PLANER ON THE JOB SITE.

Improper flail and spacer washer setup. See FLAIL DESIGN AND APPLICATION.

Accumulation of foreign material. Clean and/or replace the flails and spacer washers as necessary.

Flails and/or spacer washers are too tight on the drum. Remove and/or replace flails and spacer washers. See FLAIL DRUM RODS.
