OII Recommendations
Only use high quality detergent oil rated with
API service classification SG. Select the oil's
SAE viscosity grade according to your ex-
pected operating temperature. Although mul-
ti-viscasity oils (5W30, 10W30, etc.) improve
starting in cold weather, these multi-viscosity
otis will result in increased oil coflsumption
when used above 32 degrees. Check the
engine oil level more frequently to avoid pos-
sible engine damage from running the en-
gine low on oil,

EDGING TIPS
• Edging is best performed when cor_liUo_s
are dry. If the soil is to wet, dirt becomes
packed around the blade causing prema-
ture belt wear and decreased partor-
mancs.
• If dirt does become packed around the
blade, stop the engine and remove the
wire from the spark plug. Remove the
packed dirt and debris from the blade.
•Fordeapedging, firstcutat shallow
depths.Then, cutat greaterdepthsuntil
the desireddepthisobtained.
•Foruniformedging, makesurethe blade
guideddesonthe surface.
•Edgingcanbe customizedby varyingthe
numberof passesandby thedistancethe
bladeisfromthe surtaca.
A ARNING: Read the Owner's
manuel. Know location and
functions of all controls. Keep
all safety devices end shleids in place,
Never allow children or unlnstruofed
adults to operate Edger. Shut off engine
before unclogging blade or making re-
palre. Keep bystanders away from me.
