Throttle lever
To prevent the throttle lever (1) from being accidentally pulled, a lock-off lever
(2) is provided. To increase the engine speed, grasp the rear handle (the lock-
off lever is released by the grasp) and then pull the throttle lever.
To decrease the engine speed, release the throttle lever.
Adjustment of low-speed rotation (idling)
When it is necessary to adjust the low-speed rotation (idling), perform it by the
carburetor adjusting screw.
Checkup of low-speed rotation
CAUTION:
The cutting attachment may be spinning during carburetor adjustments. Wear
your protective equipment and observe all safety instructions. Be sure the
cutting attachment stops turning when the engine idles.
CAUTION:
When the unit is turned off, make sure the cutting attachment has stopped
before the unit is set down.
– Set the low-speed rotation to 3,000 min
If it is necessary to change the rotation speed, regulate the adjusting screw
(1) with Phillips screwdriver.
– Turn the adjusting screw to the right, and the engine rotation will increase.
Turn the adjusting screw to the left, and the engine rotation will drop.
– The carburetor (2) is generally adjusted before shipment. If it is necessary to
readjust it, please contact Authorized Service Agent.
MAINTENANCE
CAUTION: Before doing any work on the Petrol Brushcutter, always stop the engine and pull the plug cap off the spark plug (see "checking the
spark plug").
Always wear protective gloves!
To ensure a long service life and to avoid any damage to the equipment, the following servicing operations should be performed at regular
intervals.
Daily checkup and maintenance
– Before operation, check the machine for loose screws or missing parts. Pay particular attention to the tightness of the cutter blade or nylon
cutting head.
– Before operation, always check for clogging of the cooling air passage and the cylinder fins.
Clean them if necessary.
– Perform the following work daily after use:
• Clean the Petrol Brushcutter externally and inspect for damage.
• Clean the air filter. When working under extremely dusty conditions, clean the filter the several times a day.
• Check the blade or the nylon cutting head for damage and make sure it is firmly mounted.
• Check that there is sufficient difference between idling and engagement speed to ensure that the cutting tool is at a standstill while the
engine is idling (if necessary reduce idling speed).
If under idling conditions the tool should still continue to run, consult your nearest Authorized Service Agent.
– Check the functioning of the I-O switch, the lock-off lever, the control lever, and the look button.
Metal blade resharpening
CAUTION:
The metal blades must only be resharpened by an authorized facility. Manual resharpening may result in imbalances of the cutting tool causing
vibrations and damage to the equipment.
NOTE: To increase the service life of the cutter blade it may be turned over once, until both cutting edges have become blunt.
