Idle Speed Adjustment
POTENTIAL HAZARD
•
Engine must be running to make idle speed
carburetor adjustments.
•
When engine is running, the blades may
move.
WHAT CAN HAPPEN
•
Contact with blades or other moving parts
could cause serious personal injury or
death.
HOW TO AVOID THE HAZARD
•
Keep hands, feet and clothing away from
blades and other moving parts.
•
Keep all bystanders and pets away from
unit while making carburetor adjustments.
This Hedge Trimmer is equipped with a
non-adjustable fuel mixture carburetor. The engine
idle speed is the only adjustment for the operator.
The cutting blades may be moving during idle speed
adjustment. Wear the recommended personal
protective equipment and observe all safety
instructions. Keep hands and body away from the
blade area.
When the throttle trigger is released, the engine
should return to an idle speed between 2700 and 3300
RPM, or just below the clutch engagement speed.
The cutting blades must not move and the engine
should not stall (stop running) at engine idle speed.
To adjust the engine idle speed, rotate the idle speed
adjustment screw on the carburetor (Fig. 8).
•
Turn the idle speed screw in (clockwise) to
increase the engine idle speed.
•
Turn the screw out (counterclockwise) to
decrease the engine idle speed.
If idle speed adjustment is necessary, and if after
adjustment the cutting blades move or the engine
stalls, stop using the Hedge Trimmer immediately!
Contact your local authorized Toro Dealer for
assistance and servicing.
Operation
•
Read the Safety instructions on page 2
concerning proper use of the Hedge
Trimmer.
The Toro Hedge Trimmer is designed for cutting and
trimming foliage and small branches up to 1/4 inch
(6mm) in diameter. Although the Toro Hedge
Trimmer is capable of cutting larger diameter
branches, wear and tear on the machine would be
proportionally increased.
•
Always wear gloves and protective clothing
when operating the Hedge Trimmer.
•
If the cutting blades become jammed, stop the
engine immediately.
•
Make certain all moving parts have stopped and
disconnect the spark plug before inspecting the
equipment for damage.
•
Never use a Hedge Trimmer that has chipped,
cracked or broken cutting blades.
