This document outlines the operation, safety, and maintenance procedures for a Husqvarna 128CD and 128LD trimmer/brushcutter. It emphasizes safe handling, proper assembly, and routine upkeep to ensure optimal performance and longevity of the machine.
The Husqvarna 128CD and 128LD are designed primarily for trimming grass and clearing unwanted vegetation. They are equipped with a two-stroke engine that powers a cutting attachment, typically a trimmer head with flexible line. The machine is intended for outdoor use and is suitable for tasks such as cutting grass in hard-to-reach areas, around trees, posts, and along borders. It can also be used for sweeping light debris. The 128LD model offers a two-piece shaft design, allowing for the attachment of various accessories like edgers, cultivators, blowers, brushcutters, and pruners, extending its versatility beyond basic trimming.
The trimmer features a loop handle for comfortable and secure gripping during operation. The throttle control and throttle lock-out mechanism are designed to prevent accidental acceleration, ensuring the cutting attachment remains stationary at idle. A stop switch allows for quick engine shutdown.
Starting the engine involves a specific sequence: pressing the primer bulb multiple times to fill it with fuel, moving the choke lever to the closed position, and then firmly pulling the starter rope handle. For a warm engine, the choke lever is moved to the 1/2 position. The machine should always be started on a flat surface, away from the refueling area, and with the cutting attachment clear of any objects.
When trimming, the operator should hold the trimmer head just above the ground at an angle, allowing the end of the trimmer line to do the work. For clearing, the trimmer head can be tilted to remove all unwanted vegetation, but this increases wear on the trimmer line. Sweeping involves holding the trimmer line parallel to and above the area to be swept, using the fan effect of the rotating line to clear debris. Full throttle is recommended for both cutting and sweeping to achieve the best results.
The two-piece shaft on the 128LD model allows for easy assembly and dismantling of attachments. This involves loosening a coupling knob, pressing a locking/release button, and pulling the attachment straight out. When fitting an attachment, the locking/release button must align with a guide recess and snap into the primary hole.
Safety is paramount during use. Operators are instructed to wear personal protective equipment, including hearing protection, approved eye protection (goggles and/or a visor), gloves, sturdy non-slip boots, and heavy, long pants. Loose clothing, jewelry, and long hair should be secured. The working area must be inspected for objects that could be thrown by the cutting head, and a safety zone of 50 feet (15 meters) should be maintained around the operator to protect bystanders and animals. The machine should never be used if the cutting attachment guard is damaged or missing, or if any other safety equipment is faulty.
Regular maintenance is crucial for the machine's performance and safety. The manual provides a detailed maintenance schedule, including daily, weekly, and monthly checks.
Daily maintenance includes checking the throttle trigger and lock-out function, ensuring the stop switch works, inspecting for fuel leaks, verifying that the cutter does not rotate at idle, cleaning the machine's exterior, checking the harness for damage, and inspecting the cutting attachment guard for damage or cracks. The trimmer head should also be checked for tightness and balance to prevent heavy vibrations.
Weekly maintenance involves checking the starter and starter cord, cleaning the carburetor area, and inspecting and cleaning the spark plug. The electrode gap should be adjusted to 0.024" (0.6 mm), or the spark plug should be replaced with a Champion RCJ-6Y or equivalent. Cooling fins on the cylinder and the air intake near the starter should be cleaned. The bevel gear (on the 128LD model) should be checked to ensure it is filled three-quarters full with HUSQVARNA special grease, and the air filter should be cleaned.
Monthly maintenance extends to cleaning the fuel tank, the exterior of the carburetor, and the fan area. Fuel lines should be checked for cracks and replaced if necessary. The fuel filter in the tank should be changed. The clutch, clutch springs, and clutch drum should be inspected for wear and replaced if needed. Electrical wires and connections should be checked, and the spark plug and air filter should be replaced.
The carburetor's idle speed (T-screw) can be fine-tuned if the cutting attachment rotates at idle. The T-screw should be turned counterclockwise until the cutting attachment stops. If the idle speed cannot be adjusted to prevent rotation, professional service is required.
Fuel handling is also a key maintenance aspect. The machine requires a mixture of unleaded gasoline and two-stroke oil (2%, or 1:50 ratio). The manual specifies using HUSQVARNA two-stroke oil for optimal performance and recommends synthetic oil for extended trimmer life. Fuel should be mixed in a clean container, starting with half the gasoline, adding all the oil, mixing, and then adding the remaining gasoline. The fuel mixture should be thoroughly shaken before filling the tank. It is advised not to mix more than one month's supply of fuel at a time and to empty and clean the fuel tank if the machine will not be used for an extended period.
The muffler is equipped with a spark arrestor mesh that needs regular checking and cleaning by a servicing dealer. A blocked mesh can cause the machine to overheat and damage the cylinder and piston. The drive shaft end in the lower shaft of the two-piece model should be lubricated with grease every 30 hours to prevent seizing.
Overall, the manual emphasizes that proper maintenance, as outlined, is essential for the machine's safe and efficient operation, extending its lifespan, and ensuring compliance with emission control regulations.
