1. Safety Instructions
Always prioritize safety when operating the Hecht 890 Log Saw. Failure to follow these instructions can result in serious injury or property damage.
- Read the Manual: Before assembly, operation, or maintenance, read and understand this entire manual.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety glasses, hearing protection, heavy-duty gloves, and sturdy footwear. Avoid loose clothing that could get caught in moving parts.
- Work Area: Operate the log saw on a firm, level surface. Keep the work area clear of bystanders, children, and pets. Ensure adequate lighting.
- Fuel Safety: Handle gasoline with extreme care. Store fuel in approved containers, away from ignition sources. Refuel outdoors and never while the engine is running or hot.
- Blade Safety: The saw blade is extremely sharp. Never touch the blade when the machine is running or when it is connected to a power source (for electric models). Ensure the blade guard is always in place and functioning correctly.
- Secure Workpiece: Always ensure the log is securely positioned in the cradle before cutting. Do not attempt to cut logs that are too large or irregularly shaped for the machine.
- Emergency Stop: Familiarize yourself with the location and operation of the emergency stop mechanism.
- Maintenance: Disconnect the spark plug wire (for gasoline models) or power cord (for electric models) before performing any maintenance or adjustments.
2. Setup and Assembly
The Hecht 890 Log Saw requires some assembly before first use. Follow these steps carefully to ensure proper and safe setup.
2.1 Unpacking
Carefully remove all components from the packaging. Check the contents against the packing list to ensure all parts are present and undamaged. Report any missing or damaged parts to your dealer immediately.
2.2 Attaching the Wheels and Support Legs
Attach the wheels to the main frame using the provided axles and fasteners. Ensure they are securely tightened. Then, attach the support legs to provide stability. The robust chassis allows for easy transport, even on various surfaces.

3. Operating Instructions
Follow these steps for safe and effective operation of your Hecht 890 Log Saw.
3.1 Starting the Engine
- Ensure the log saw is on a stable, level surface.
- Check fuel and oil levels.
- Set the choke and throttle according to the engine's starting procedure (refer to the engine manual if necessary).
- Pull the recoil starter handle firmly until the engine starts.
- Once started, gradually return the choke to the "run" position.
3.2 Loading Logs
Place the log securely into the V-shaped cradle. For longer logs, utilize the robust support extension to ensure stability. The rocking lever mechanism supports the wood and guides it towards the saw blade.

3.3 Cutting Procedure
- Ensure the log is firmly seated in the cradle and the rocking lever is locked in position.
- With both hands on the handles, slowly push the rocking lever forward, guiding the log into the spinning blade.
- Apply steady, even pressure. Do not force the cut.
- Once the cut is complete, slowly pull the rocking lever back to its original position. The saw blade is protected by a cover and a latching mechanism for the rocking lever ensures safety during operation.
- Remove the cut piece and repeat for the next cut. The saw can cut logs up to 230 mm thick.

4. Maintenance
Regular maintenance ensures the longevity and safe operation of your Hecht 890 Log Saw.
4.1 General Cleaning
After each use, clean the machine thoroughly. Remove sawdust, wood chips, and debris from the blade guard, cradle, and engine cooling fins. Use a brush or compressed air. Never use water directly on the engine or electrical components.
4.2 Blade Inspection and Replacement
Regularly inspect the saw blade for sharpness, damage, or missing carbide tips. A dull or damaged blade can cause kickback and reduce cutting efficiency. Replace the blade when necessary, following the installation steps in section 2.3. Always use genuine Hecht replacement blades.
4.3 Engine Maintenance
Refer to the separate engine manual for detailed maintenance schedules, including oil changes, air filter cleaning/replacement, and spark plug inspection. Ensure the oil level is always correct to prevent engine damage, especially with the oil level shutdown automatic feature.
4.4 Lubrication
Lubricate moving parts, such as the rocking lever pivot points, periodically with appropriate grease or oil to ensure smooth operation and prevent wear.
