Maintenance and care
Every unit is test run at the factory and the carburettor is fine
tuned for maximum performance.
Before adjusting carburettor, clean or replace air filter, start en-
gine and run several minutes to bring it to operating temperature.
The engine must return to idle speed whenever the throttle lever
is released. Idle speed is adjustable, and must be set low enough
to permit the engine clutch to disengage the cutting attachment.
To adjust the carburettor proceed as follow:
1. Place the unit on the ground, then start the engine, and then
allow it to idle 2-3 minutes until warm.
2. If the attachment moves when the engine is at idle, reduce
the idle speed by turning the idle adjustment screw(T) coun-
ter-clockwise.
3. If a tachometer is available, the engine idle speed should be
final adjusted to 3000 (±500) rpm (min
NOTE
When the carburettor cannot be adjusted properly with the idle
speed adjustment screw (T), you must contact an authorized
service dealer.
Prior to each work day, perform the following:
Remove all dirt and debris from the engine, check the cooling
fins and air cleaner for clogging, and clean as necessary.
Carefully remove any accumulations of dirt or debris from the
silencer and fuel tank. Check cooling air intake area at base of
crankcase. Remove all debris. Dirt build-up in these areas can
lead to engine overheating, fire, or premature wear.
Lubricate the blade before use and after refueling. Check the
cutter for damage or incorrect adjustment.
Always wear gloves when working around the cutter as-
sembly.
Failure to observe the precautions could cause an accident
or injury, or even lead to a fatality.
Clean any debris or dirt from the cutting attachment.
Check for loose or missing screws or components. Make sure
the cutter attachment is securely fastened.
Check the entire unit for leaking fuel or grease.
Make sure nuts, bolts, and screws (except carburetor idle
speed adjusting screws) are tight.
