of any other parts may create a hazard or cause product

damage.

WARNING:

Always wear eye protection with side shields marked to

comply with ANSI Z87.1, along with hearing protection.

Failure to do so could result in objects being thrown into

your eyes and other possible serious injuries.

WARNING:

Before inspecting, cleaning or servicing the machine, shut

off engine, wait for all moving parts to stop, and disconnect

spark plug wire and move it away from spark plug. Failure

to follow these instructions can result in serious personal

injury or property damage.

GENERAL MAINTENANCE

Before each use, inspect the entire product for damaged,

missing, or loose parts such as screws, nuts, bolts, caps, etc.

this product until all missing or damaged parts are replaced.

Please call 1-800-860-4050 or contact an authorized service

center for assistance.

Avoid using solvents when cleaning plastic parts. Most plastics

are susceptible to damage from various types of commercial

solvents and may be damaged by their use. Use clean cloths

to remove dirt, dust, lubricant, grease, etc.

based products, penetrating lubricants, etc., come in con-

tact with plastic parts. Chemicals can damage, weaken or

destroy plastic which may result in serious personal injury.

CLEANING THE AIR FILTER

See Figure 18.

Clean the air filter as indicated by the maintenance schedule.

To clean the air filter:

Depress the latch located below the air filter cover. Then,

lift the cover away from the locking tabs and remove it from

the unit.

Remove the air filter.

 Rinse filter with clean water.

 Gently squeeze filter until excess water is removed.

 Apply a light coat of engine lubricant to the filter, then squeeze

it out.

Reinstall the air filter.

NOTE: Make sure the filter is seated properly inside the

cover. Installing the filter incorrectly will allow dirt to enter

the engine, causing rapid engine wear.

Reinstall the air filter cover making sure that the locking tabs

on the unit and the holes in the air filter cover are aligned.

To secure, press against the air filter cover until the latch

below the cover snaps in place.

NOTE: For best performance, the air filter should be replaced

once each year.

FUEL CAP

WARNING:

Check for fuel leaks. A leaking fuel cap is a fire hazard

and must be replaced with an original manufacturer’s

replacement cap immediately. If you find any leaks, correct

the problem before using the product. Failure to do so could

result in a fire that could cause serous personal injury.

The fuel cap contains a non-serviceable filter and a check

valve. A clogged fuel filter will cause poor engine performance.

If performance improves when the fuel cap is loosened, check

valve may be faulty or filter clogged. Replace fuel cap if required.

REPLACING THE SPARK PLUG

See Figure 19.

This engine uses a Champion RY4C spark plug with .025 in. elec-

trode gap. Use an exact replacement and replace annually.

Remove the screw on top of the engine housing. This will

allow the engine housing to uncover as shown in figure 18.

Remove the spark plug wire.

Loosen the spark plug by turning it counterclockwise with

a socket.

Remove the spark plug.

Hand thread the new spark plug, turning it clockwise.

Tighten with a socket and torque to 170 in. lb. minimum,

190 in. lb. maximum. Do not overtighten.

Secure the engine housing back into place and return the

screw. Ensure that the housing is stable.

CAUTION:

Be careful not to cross thread the spark plug. Cross thread-

ing will seriously damage the product.

REPLACING THE SPARK ARRESTOR

hours or yearly to ensure proper performance of your product.

Spark arrestors may be in different locations depending on

the model purchased. Please contact your nearest service

dealer for the location of the spark arrestor for your model.
