CAUTION:1. When preparing fuel mixture, mix only the amount needed for the
job you are to do.
Do not use fuel mixture that has been stored longer than two
months.
Fuel mixture stored longer than two months will cause hard
starting and poor performance.
If fuel mixture has been stored longer than this time, it should be
removed and filled with a fresh mixture.

RESHARPENING THE CUTTING TOOL
Dam
CAUTION: The cutting tools mentioned below must only be resharpened by an
authorized facility. Manual resharpening will result in imbalances
of the cutting tool causing vibrations and damage to the equipment.
- cutter blade (star blade (4 teeth), eddy'blade (8 teeth), saw blade) Ч
An expert resharpening and balancing service is provided by Authorized
Service Agents. ‚
NOTE: To increase the service fife of the cutter blade (star blade, eddy blade,
saw blade) it may be turned over once, until both cutting edges have
become blunt.
NYLON CUTTING HEAD
The nylon cutting head is a dual string frimmer head capable of both automatic and bump & feed mechanisms.
The nylon cutting head will automatically feed out the proper length of nylon cord by the changes in centrifugal force caused by | increasing or
decreasing min". However, to cut soft grass more efficiently, pump the nylon cutting head against the ground to feed out extra cord’as -
indicated under operation section. |

SERVICING INSTRUCTIONS
CAUTION: Before doing any work on the brush cutter, always switch off the
motor 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. A | a
— 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 brush cutter 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
