6. Maintenance
For normal operation, annually re-lubricate both motor bearings with approximately ten (10) drops of
5W-30 oil. The gears of the gearbox assembly are lubricated with a special high temperature, food grade
lubricant (SPD-2109) at the time of manufacturing. The level of grease in the gearbox should be checked
annually and will not normally require further lubrication unless seal breakage occurs. After the grease has
settled to the bottom of the gearbox, the grease level can be checked. The grease level should not be more
than 1/4" below the vent plug.
(See Figure 6A.)
It may be necessary to insert a wire through vent plug hole
to determine the grease level. The grease level also can be checked by removing motor and viewing
grease level through the hole for the motor pinion gear.
Inspect seals annually for signs of leakage (check bearings annually for tightness).
In the event the motor fails to start, check power supply to the motor. If power supply exists and motor still
fails to start, disconnect power and check blade for freedom of rotation. If power does not exist, check for
blown fuse or flipped circuit breaker.
If motor stops operating for no apparent reason, wait approximately 5 minutes for the automatic overload
protection device to reset and reattempt operation. If problem continues, check power supply for voltage
and check blade of unit for freedom of rotation.
If motor pinion requires removal for any reason, it must be properly installed and located, as shown in the
parts assembly
on Page 18

WARNING
Disconnect power supply before attempting any type of service. The motor is
protected with a self-resetting overload protection.
DANGER
Failure to disconnect power can result in serious injury or death.
