After using the hedge trimmer for 40 hours, you must check whether the screws are loose. If they are loose, be sure to tighten them, otherwise the blades will easily fall off, which will seriously threaten the user's personal safety.
Regularly check the gap between the upper and lower blades of the blade, and adjust them in time to keep the cutting edge sharp; clean the blade regularly (every 8 to 20 hours) to remove dust and dirt on the blade; add oil to the blade every hour of work , To ensure the life of the blade.
Check the spark plug regularly. This is because the spark plug is damaged, which will cause failures such as insufficient engine power, difficulty in starting or idling. In severe cases, it may cause sparks and fire. Therefore, the spark plug of the hedge trimmer must be checked regularly.
If it is a gasoline hedge trimmer, after 24 hours of use, the dust attached to the air filter should be removed. If the working environment is dusty, the interval should be shortened. When not in daily use, the damper of the air filter should be adjusted to the choke position to prevent dirt from entering the intake pipe and affecting subsequent use.
