Think of it like knowing the ingredients in a recipe – you can’t bake a cake without knowing what goes in it!
- Battery Voltage: 36 V. This is important because it dictates the power and runtime of the saw. A higher voltage generally means more power and longer run times.
- Weight (without battery): Approximately 10.8 lbs (4.9 kg). This is a significant factor, especially when working overhead.
- Cutting Length: Typically around 12 inches (30 cm). This determines the maximum branch diameter you can cut in a single pass.
- Total Length: Extends up to around 13 feet (4 meters) depending on the specific model and extension.
- Chain Speed: Varies depending on the load, but typically around 12-16 m/s.
- Oil Tank Volume: Around 4.6 oz (135 ml). Keep an eye on this, as a dry chain is a damaged chain.
Why this matters: Knowing the weight helps you anticipate fatigue during extended use. The cutting length determines the size of branches you can tackle. The battery voltage indicates the power and run time. Always check the user manual for the exact specifications of your model.
My Experience: I once underestimated the weight of the HTA 135 during a particularly long pruning session. By the end, my arms were aching, and my technique suffered. Now, I always plan my work in shorter bursts, with regular breaks to avoid fatigue.
Data Point: A study by the National Institute for Occupational Safety and Health (NIOSH) found that prolonged overhead work with heavy tools significantly increases the risk of musculoskeletal disorders.
2. Mastering the Art of Battery Management
The beauty of an electric pole saw is its cordless operation. The bane of its existence is running out of battery mid-cut. I’ve been there – perched precariously on a ladder, halfway through a thick branch, only to have the saw sputter and die. Battery management is key to avoiding such frustrating scenarios.
- Battery Type: Lithium-ion (Li-ion) – Known for their high energy density and long lifespan, if cared for properly.
- Charging Time: Varies depending on the battery and charger, but typically 30-60 minutes for a full charge.

Technical Insight: Chain oil viscosity is crucial for proper lubrication. In colder climates, use a lower viscosity oil to ensure it flows freely. In warmer climates, use a higher viscosity oil to prevent it from thinning out too much. The ideal viscosity range is typically between 80 and 120 SUS at 100°F (38°C).
Wood Selection and Firewood Preparation (Bonus Section)
While the HTA 135 excels at pruning, it can also be used for preparing smaller pieces of firewood. Understanding wood types and proper drying techniques is essential for producing high-quality firewood.
Wood Selection Criteria
The type of wood you choose significantly impacts its burning characteristics.
- Hardwoods vs. Softwoods: Hardwoods (e.g., oak, maple, ash) are denser and burn longer, producing more heat. Softwoods (e.g., pine, fir, spruce) burn faster and produce more smoke.
- Density: Higher density woods generally have a higher BTU (British Thermal Unit) content, meaning they release more heat when burned.
- Moisture Content: Freshly cut wood can have a moisture content of 50% or higher. Firewood should be dried to a moisture content of 20% or less for optimal burning.
Data Point: Oak typically has a BTU rating of around 28 million BTUs per cord, while pine has a BTU rating of around 20 million BTUs per cord.
Technical Insight: Wood density is measured in kilograms per cubic meter (kg/m³). Oak, for example, has a density of around 750 kg/m³, while pine has a density of around 400 kg/m³.
Firewood Drying Techniques
Proper drying is crucial for producing clean-burning, efficient firewood.
- Splitting: Split wood dries faster than unsplit wood. Splitting increases the surface area exposed to air.
- Stacking: Stack wood in a single row, off the ground, with good air circulation.
- Location: Choose a sunny, windy location for your woodpile.
- Drying Time: Drying time varies depending on the wood type, climate, and stacking method, but typically takes 6-12 months.
My Experience: I used to think I could get away with burning wood that wasn’t fully dry. I quickly learned that wet wood is difficult to ignite, produces a lot of smoke, and doesn’t generate much heat. Now, I’m patient and always wait for the wood to dry properly.
Data Point: The moisture content of firewood can be measured using a moisture meter. A moisture meter is an invaluable tool for ensuring that your firewood is properly dried.
Technical Insight: Wood shrinks as it dries. The amount of shrinkage varies depending on the wood type, but can be as much as 10% in volume. This shrinkage can cause cracks and checks in the wood, which can actually improve drying by increasing surface area.
