Carburetor Adjustment

Before adjusting the carburetor, clean the cover vents and air
filter as shown in Illustration (Fig.73-74), refer to Operation-
Starting Unit and Maintenance-Air Filter Sections for details.
Allow the engine to warm up prior to carburetor adjustment.
This engine is designed and manufactured in order to comply
with EPA (Environmental Protection Agency) Phase 3 regulations.
WARNING: Don't try to force the screws outside the
range!
WARNING: Don't modify the carburetor in any way in
such case the engine will not run in compliance with
emissions regulations.
Idle Speed Adjustment
• If the engine starts, runs, and accelerates but will not idle; turn
the idle speed screw "T" clockwise to increase idle speed
(Fig. 75).
• If the cutting attachment turns at idle, turn the idle speed
screw "T" counter-clockwise to reduce the idle RPM and stop
the cutting attachment movement.
WARNING: If the cutting attachment still moves at idle
speed, contact a Servicing Dealer for adjustment and
discontinue use until the repair is made.

affect carburation.

Fuel Filter

Check the fuel filter (Fig. 76) periodically. Replace it if contaminated
or damaged.

Air Filter

WARNING: Do not clean filter in gasoline or other
flammable solvent to avoid creating a fire hazard or
producing harmful evaporative emissions.
If a power drop is noticed, check the air filter. Open the air filter
cover (A) and check the air filter (B, Fig.74) each day, change the
filter if heavily clogged or damaged.
Blow with compressed air, at a distance. Reinstall the air filter into
cover. Place the air filter cover onto the pole pruner. Tighten the
air filter cover screw securely.
A used air filter can never be completely cleaned. It is advisable
to replace your air filter with a new one after six month of
operation.
Make sure the cover and the support are clean before fitting the
new filter.
