■ BLADES (MA1) | QUICK TIP |
•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.
If the blades become so worn down that it is no longer possible to eliminate the gap between them, you should contact the authorized RedMax servicing dealer from which you purchased your RedMax trimmer to have the blades resharpened or replaced.
MA1
1.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

■GEAR CASE
The reduction gears are lubricated by multipurpose,
When adding lubricant, use a grease gun to insert lubricant into the three grease nipples located on the gear case. (MA2)
TYPE OF LUBRICANT TO BE USED
NOTE
Always be sure to use #2 lithium
• Screwing in the screw too tightly may | (1) Grease fitting |
make it impossible for the blades to |
|
move. Conversely, not screwing 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. |
