POWER AUGER MAINTENANCE
1. The gear case has 4 oz. of grease installed at the factory. It is
recommended that once a year the gear case be split and the 
grease level checked. Add grease only if level of grease is below 
top of the gears. 
dO NOT OVERFILL.
2. Keep all screws, nuts, and bolts tight.
3. For cold weather operation, store the unit in a cool environment. 
Transferring the unit from a warm to a cold place can cause the 
build up of harmful condensation.
4. If blade performance decreases, turn unit off and disconnect
spark plug wire. Carefully inspect cutting edge of blade for any 
signs of wear. If blades show any of these signs, they need to be 
sharpened or replaced.
ENGINE MAINTENANCE
Please read the maintenance schedule and observe these recom-
mendations to extend the life of your engine.
Good maintenance is essential for safe, economical, and trouble-
free operation. It will also help reduce air pollution. To help you 
properly care for your engine, the following pages include a 
maintenance schedule, routine inspection procedures, and simple 
maintenance procedures using basic hand tools. Other service 
tasks that are more difficult, or require special tools, are best 
handled by professionals and are normally performed by a techni-
cian or other qualified mechanic. 
Maintenance, replacement or repair of the emissions control devices 
and systems may be performed by any non-road engine repair 
establishment or individuals. However, items must be serviced by an 
authorized dealer to obtain "no charge" emissions control service. 
The maintenance schedule applies to normal operating condi-
tions. If you operate your engine under unusual conditions, such 
as sustained high-load or high-temperature operation, or use in 
unusually wet or dusty conditions, consult your servicing dealer for 
recommendations applicable to your individual needs and use.
