STARTING POSITION

WARNING: When starting engine, hold the unit as illustrated. Do not set unit on any surface except a clean, hard area when starting engine or while engine is running. Debris such as gravel, sand, dust, grass, etc. could be picked up by the air intake and thrown out through the discharge opening, damaging the unit or property, or causing serious injury to by- standers or the operator.

BLOWER OPERATION

When the engine has warmed up, the blower can be positioned on the back of the operator. Once the blower is positioned and ready for operation, adjust the throttle to a speed re- quired to accomplish the task.

NOTE: Always run the engine at idle speed for a few minutes to allow cooling before stop- ping the engine.

We recommend all service and adjustments not listed in this manual be performed by an Authorized Service Dealer.

CARBURETOR ADJUSTMENTS

Your carburetor is equipped with limiter caps. Carburetor adjustment is a complicated task. We recommend that you take your unit to an Authorized Service Dealer. Damage may occur if you turn the needles beyond the limiter stops.

IGNITION TIMING

Ignition timing is fixed, non-adjustable.

SPARK PLUG

Replace the spark plug yearly using a Cham- pion RCJ--7Y plug. Spark plug gap is .025”.

AIR FILTER

CAUTION: Do not clean filter in gasoline or other flammable solvent to avoid creating a fire hazard or producing harmful evaporative emissions

A dirty air filter decreases engine perfor- mance and increases fuel consumption and harmful emissions. Always inspect the air fil- ter each time you use the blower (more often in extreme conditions) by removing the air fil- ter cover.
