Idle Speed Adjustment; Spark Plug Replacement - Ryobi RHT2660DAG Operator's Manual

FUEL CAP
WARnInG:
A leaking fuel cap is a fire hazard and must be replaced
immediately.
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.

IDLE SPEED ADJUSTMEnT

See Figure 11.
If the blades move 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 blade movement. If the
blades still move at idle speed, contact a service dealer for
adjustment and discontinue use until the repair is made.
WARnInG:
The blades should never move at idle. Turn the idle
speed screw counterclockwise to reduce the idle
RPM and stop the blades, or contact a service dealer
for adjustment and discontinue use until the repair is
made. Serious personal injury may result from the
blades turning at idle.

SPARK PLUG REPLACEMEnT

This engine uses a Champion RCJ6Y with .025 in. electrode
gap. Use an exact replacement and replace annually.

2. Loosen the spark plug by turning it counterclockwise with
a 16 mm socket.
3. Remove the spark plug.
4. Hand thread the new spark plug, turning it clockwise.
note: A small amount of anti seize compound on the
thread of the new plug will ensure easy removal on the
next service.
5. Tighten with a socket. Do not overtighten.
WARnInG:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product
CLEAnInG THE EXHAUST PORT AnD MUFFLER
Depending on the type of fuel used, the type and amount of
lubricant used, and/or your operating conditions, the exhaust
port and muffler may become blocked with carbon deposits.
If you notice a power loss with your petrol powered tool, you
may need to remove these deposits to restore performance.
We highly recommend that only qualified service technicians
perform this service.
