I. Fuel System Scientific Ratio and Storage Management

As an overseas distributor, incorrect fuel ratios are the primary cause of customer after-sales complaints. According to international two-stroke engine standards, TMAX chainsaws recommend a 1:50 mixture ratio (1 part TC grade special engine oil + 50 parts 90 octane or higher unleaded gasoline). During the break-in period (first 30 hours) of a new machine, this can be adjusted to 1:40 to enhance lubrication protection. Pay special attention to E10 gasoline (containing 10% ethanol), which is commonly used in the European and American markets. Remind customers to clean the carburetor promptly after use and adjust parameters if necessary. Regarding storage, it is best to prepare and use the mixed oil immediately, and store it for no more than 30 days. Chainsaws stored for extended periods should have their fuel tanks emptied and residual fuel from the purifier burned off. It is recommended to provide downstream customers with a mixing measuring cup as an added-value accessory, which lowers the barrier to entry and reduces the after-sales rate of engine cylinder scoring failures due to incorrect mixing.

II. Wear Control and Maintenance of Saw Chains and Guide Plates

Saw chains and guide plates are high-frequency wear components; proper maintenance can increase customer repurchase rates. Three checks should be performed before daily use: ① Rotate the guide plates to ensure even wear; ② Clean blockages from the guide plate grooves and lubrication holes, and check if the oil line output is normal; ③ Adjust the saw chain tension when the machine is cold, ensuring it can be manually pulled and the guide teeth are parallel to the guide plate. The wear judgment criteria should be clearly communicated to customers: When chain links show cracks, rivets become loose, or the sprocket at the tip of the guide plate wobbles, the parts must be replaced. We recommend stocking TMAX genuine saw chain and guide plate sets, along with maintenance tools such as files, and guiding customers to polish the chain every 8 hours of work to extend its service life by more than 30%.

III. Air Filter Tiered Cleaning Standards

The frequency of air filter cleaning directly affects engine power output and should be tiered according to the operating environment: daily cleaning is recommended in dusty environments, and maintenance every 25 hours under normal operating conditions. The cleaning process must be standardized: ① Close the choke during disassembly to prevent debris from entering the cylinder; ② Wash foam filters with warm soapy water, dry, soak in engine oil, and then squeeze out excess grease (except for filters marked "DO NOT OIL"); ③ Felt filters cannot be washed with water; simply tap or blow them clean with compressed air in the reverse direction. As a dealer, we can provide a dedicated cleaning kit, while emphasizing that uncleaned filters can lead to a more than 30% decrease in engine power and increased after-sales maintenance costs.

IV. Regular Spark Plug Inspection and Gap Calibration

Spark plug maintenance is crucial for improving the starting performance of your chainsaw. It is recommended to inspect them every 25 hours. When cleaning, use a wire brush to remove carbon buildup from the electrodes. Strictly control the core parameters: electrode gap calibration should be 0.6-0.7mm. Replace spark plugs immediately if they have been used for more than 50 hours or if the electrodes are severely worn.

For overseas markets, remind customers to avoid prolonged high-speed idling, as this will accelerate spark plug aging. It is recommended to keep different models of spark plugs in stock to meet the maintenance needs of customers in different regions, and to include spark plug gap measurement diagrams in the product manual.

V. Lubrication System Full-Chain Maintenance Solution

Poor saw chain lubrication is one of the main causes of customer returns. A full-process maintenance system needs to be established: ① Always fill with dedicated chain oil when refueling, ensuring there is still lubricating oil remaining when the fuel is depleted; ② Never use waste engine oil. We recommend TMAX environmentally friendly biodegradable lubricating oil, which meets European and American environmental standards and prevents resin formation and blockage in the oil lines; ③ After each tank of oil is used, check the oil lines for blockages. If the oil level in the tank does not decrease, clean the filter and oil lines promptly.

For wholesalers, a "lubricating oil + oil line cleaning tool" package can be offered. Simultaneously, downstream retailers should be trained to identify lubrication failure symptoms (such as saw chain overheating and increased cutting resistance) to intervene early and reduce after-sales issues.

VI. Long-Term Inventory and Seasonal Storage Techniques

Given the characteristics of overseas warehousing and seasonal sales, inventory chainsaws require a professional storage procedure: ① Thoroughly clean the machine body, removing sawdust and oil; ② Drain the fuel tank and run the engine until the fuel is depleted; ③ Remove the spark plugs, inject 1-2ml of two-stroke engine oil into the cylinder, pull the starter 2-3 times, and then reset; ④ Loosen the chain tension, apply rust-preventive oil to the guide plates, and seal for storage.

Before the peak sales season, a comprehensive inspection of inventory products is necessary: ​​start-up tests, chain tension adjustments, and oil circuit clearing to ensure optimal condition upon delivery to customers. It is recommended to provide long-term partners with an inventory maintenance manual to reduce product storage losses.
