WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which can result in serious personal injury.
You can often make adjustments and repairs described
here. For other repairs, have the power head serviced by
an authorized service dealer.
IDLE SPEED ADJUSTMENT
See Figure 9.
WARNING:
The blade/cutting head will move when adjusting the
idle speed. Wear all protective clothing and keep all by-
standers, children, and pets at least 50 ft. away. Make
adjustments with the unit supported by hand so that the
blade/cutting head does not contact the ground or any
object. Keep all parts of your body away from the blade/
cutting head and muffler. Failure to follow these instruc-
tions could result in serious personal injury.
If the cutting attachment turns at idle, the idle speed screw
needs adjusting on the engine. Turn the idle speed screw
counterclockwise to reduce the idle RPM and stop the cut-
ting attachment movement. If the cutting attachment still
moves at idle speed, contact a service dealer for adjustment
and discontinue use until the repair is made.
WARNING:
The cutting attachment should never turn at idle. Turn
the idle speed screw counterclockwise to reduce the
idle RPM and stop the cutting attachment, or contact a
service dealer for adjustment and discontinue use until
the repair is made. Serious personal injury can result from
the cutting attachment turning at idle.
CLEANING AIR FILTER SCREEN
See Figures 10 - 11.
For proper performance and long life, keep air filter screen
clean.
 Remove the air filter cover by pushing down on the latch
with your thumb while gently pulling on the cover.
 Brush the air filter screen lightly to clean.
 Replace the air filter cover by inserting the tabs on the
bottom of the cover into the slots on the air filter base;
push the cover up until it latches securely in place.
MAINTENANCE
FUEL CAP, TANK, AND LINES
WARNING:
Check for fuel leaks. A leaking fuel cap, tank, or lines
are a fire hazard and must be replaced 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 serious personal injury.
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine perfor-
mance. If performance improves when the fuel cap is loos-
ened, check valve may be faulty or filter clogged. Replace
fuel cap if required.
SPARK PLUG REPLACEMENT
This engine uses a Champion RY4C or equivalent spark plug
with .025 in. electrode gap. Use an exact replacement and
replace annually.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
CHANGING ENGINE LUBRICANT
See Figure 12.
For best performance, engine lubricant should be changed
after every 25 hours of operation.
To change the engine lubricant:
 Stop the engine and disconnect the spark plug wire. Allow
the engine to cool completely before proceeding.
 Remove the screw from the top engine cover and set
aside.
 Remove the screws from the bottom of the engine cover.
Remove the bottom cover and set aside.
 Remove the oil fill cap/dipstick.
 Tip power head on its side and allow lubricant to drain
from the oil fill hole into an approved container.
NOTE: Drain the lubricant while the engine is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
 Return the power head to an upright position and refill
with lubricant following the instructions in the Adding/
Checking Engine Lubricant section previously in this
manual.
 Reinstall the bottom engine cover. Replace the screws
and tighten securely.
