What are the main aspects of adjustment of irrigation and cutting machine?(1)

The cutting and irrigation machine is a good assistant for garden finishing. It is small in size, light in weight, strong and powerful.
In order to keep a good working condition and give full play to its advantages, it is very important to adjust the machine well.


The adjustment of cutting irrigation machine mainly includes the following aspects:

I. adjustment of magnetic motor

1. Adjustment of ignition advance Angle

When the gasoline engine is working, the ignition advance Angle is the degree before the upper dead point.
Adjust, remove the starter, through magneto flywheel two peep hole, unscrew the two screws fixed soleplate, adjusted using the bottom two long waist hole, such as premature ignition, will base plate along the direction of rotation of the crankshaft when engine working direction to turn to the right position, then two screws tighten, if too late, ignition is along the direction of rotation reverse as the crankshaft backplane.

2. Check and adjust the platinum gap of the magnetic motor with contact points

The piston is at the upper dead point, when the flywheel "O" streamline is aligned to the crankcase streamline position, the platinum clearance should be 0.25-0.35 mm.

Methods for adjusting platinum gap:

(1) turn the crankshaft to open the platinum gap to the maximum position;

(2) loosen the semi-round head fastening screw slightly;

(3) rotate the platinum base plate, measure with thickness gauge, adjust the platinum gap to 0.25-0.35 mm, usually new machine platinum gap qualified, ignition advance Angle should also be in the specified range.

(4) tighten the semi-circle, tighten the screw with the head, and re-check the platinum clearance. If unqualified, repeat the adjustment according to the above method.

Ii. Adjustment of spark plug clearance

After the gasoline engine has been working for a certain period of time, if the gap exceeds the specified range due to the electrode burning loss, the side electrode of the carbon accumulation adjustment should be removed, and the gap should reach the specified value of 0.6-0.7 mm.

Adjustment of carburetor

When adjusting the carburetor, the flat spring can be placed at different positions of the oil needle ring groove to achieve the purpose of adjustment.
When the flat spring is lowered, the oil supply increases.
