Maintenance Guide for Green Hedge Cutting Platform

The hedge cutter is the core component of garden machinery such as hedge trimmers and brush cutters, used for trimming shrubs, hedgerows, and other plants. The maintenance quality directly affects the pruning effect, equipment lifespan, and operational safety. The following provides a detailed explanation of maintenance points, including daily inspections, regular maintenance, and troubleshooting.

1、 Daily inspection and post use maintenance

1. Pre use inspection

• Blade status：
  • Check if the blade is sharp, without any notches or curled edges. Blunt knives can increase the load on the motor, resulting in uneven trimming.
  • exampleIf there is abnormal pulling of plants or splashing of debris during blade cutting, the machine should be stopped immediately for inspection.
• fastener：
  • Check if the blade fixing bolts and protective cover screws are loose to prevent the blade from falling off or flying out and injuring people.
• lubrication system：
  • Check the lubricating oil level of the gearbox or transmission shaft, and supplement it if it is insufficient (according to the required model in the manual).
• Electrical system (electric cutting platform)：
  • Check if the power cord is damaged and if the plug is loose to avoid the risk of electrical leakage.

2. Clean up after use

• Remove debris：
  • Use a brush to clean the blades, gearbox, and heat dissipation holes of grass and dirt to prevent corrosion or blockage.
• rust prevention treatment：
  • Apply rust proof oil (such as WD-40) on the surface of the blade, especially in humid environments where special protection is required.
• storage environment：
  • Store in a dry and ventilated place, away from direct sunlight or rain, to prevent plastic parts from aging or metal rusting.

2、 Regular maintenance (based on usage duration or frequency)

1. Blade maintenance

• sharpen a knife：
  • Polish the blade with a specialized sharpener or grinding wheel every 50 hours of use or when the blade becomes noticeably dull.
  • skillKeep the blade angle consistent (usually 30 ° -45 °) to avoid excessive wear on one side.
• Replace the blade：
  • If the blade has cracks, notches, or thickness wear exceeding one-third of the original size, it needs to be replaced immediately.

2. Maintenance of transmission system

• Gearbox maintenance：
  • Replace the gear oil (such as GL-4 80W-90) every 200 hours and clean the impurities in the oil pan.
• Belt/chain inspection：
  • Check if the drive belt is loose or cracked, and if the chain is well lubricated.
  • adjustment methodIf the belt is loose, the tensioner needs to be adjusted; The chain needs to be regularly coated with specialized lubricating grease.

3. Engine/motor maintenance (fuel powered models)

• air filter：
  • Clean or replace the filter element every 50 hours to prevent dust from entering the engine and causing wear.
• 火花塞：
  • Check the spark plug gap every 100 hours (usually 0.6-0.7mm) and replace it if necessary.
• fuel system：
  • Use clean fuel and regularly clean the sediment in the fuel tank to avoid clogging the carburetor.

3、 Common faults and solutions

Fault phenomenon	Possible reasons	Solution
The blade does not rotate	Drive belt breakage, gear jamming, motor malfunction	Replace the belt, clean the gearbox and add oil, check the motor winding or carbon brush.
Trimming unevenness	Blade passivation, unbalanced blade installation	Sharpen or replace the blade, recalibrate the blade balance.
engine stall	Fuel depletion, carbon buildup on spark plugs, clogged air filter	Add fuel, clean spark plugs, and replace air filters.
Abnormal vibration	Loose blade, bent drive shaft, loose fasteners	Tighten the blade bolts, replace the drive shaft, and check and tighten all screws.

4、 Long term storage and maintenance

1. clean：
   • Dismantle the blade and protective cover, clean up residual plant debris and oil stains.
2. rust prevention treatment：
   • Apply rust proof oil on the surface of metal parts and fill the gearbox with lubricating oil to isolate air.
3. Battery maintenance (electric cutting table)：
   • If it is a lithium battery device, it is recommended to charge it once a month to prevent deep discharge damage to the battery.
4. packaging protection：
   • Cover the equipment with a dust cover to prevent dust or moisture from entering.

5、 Safety precautions

1. Safety before operation：
   • Wear protective equipment (such as goggles, gloves, and cut pants) to ensure that there are no people or obstacles around.
2. Power off during maintenance：
   • Turn off the power or unplug the spark plug before maintenance to prevent accidental start-up.
3. Prohibit overload use：
   • Avoid cutting too thick branches (usually with a diameter of ≤ 2cm) to prevent blade breakage or motor burnout.
4. Keep children away：
   • When storing, keep the device out of reach of children and install protective covers on the blades.

6、 Suggestions for maintenance tools and spare parts

1. tool：
   • Wrenches, screwdrivers, grinders, torque wrenches (used to tighten blade bolts).
2. Spare parts：
   • Blade, belt, spark plug, air filter, gear oil, rust proof oil.
