•Before cleaning, inspecting, or repairing the unit, make sure that the engine has stopped and is cool.
•Use protective gloves whenever inspecting, removing, sharpening, and installing the blades.
BLADES
•When refilling the tank or resting, it is often a good idea to use the time to oil the cutting blades.
•If a gap exists between the upper and lower blades, follow the procedure below to adjust them so that they fit more closely together.
•Loosen lock nut (A) as shown in the diagram.
2.Tighten screw (B) fully, and then turn
3.While holding onto the screw to keep it in position, tighten the lock nut.
4.Check to make sure that the flat washer (C) is loose enough so that it may be turned by pressing on it with a finger.
(1)Upper blade
(2)Lower blade
NOTE
•Screwing in the screw too tightly may make it impos- sible for the blades to move. Conversely, not screw- ing in the screw tightly enough may make the blades of the trimmer feel dull and cause leaves and branches to become caught in the blades of the trimmer.
QUICK TIP
•If the blades become so worn down that it is no longer possible to eliminate the gap between them, you should contact the authorized ZENOAH servicing dealer from which you purchased your ZENOAH trim- mer to have the blades resharpened or replaced.
TRANSMISSION
•The inside of the transmission should be lubricant us- ing
•When adding lubricant, use a grease gun to insert lubricant into the three grease nipples located on the transmission.
TYPE OF LUBRICANT TO BE USED
Always be sure to use #2 lithium
(1) Grease fitting
