1. Introduction and Safety Information
This manual provides essential instructions for the assembly, operation, maintenance, and troubleshooting of your Wallemac 6-inch Wood Chipper Shredder, Model WCP15B. Please read this manual thoroughly before operating the machine to ensure safe and efficient use.
The Wallemac WCP15B is designed to process branches, limbs, and garden debris up to 6 inches in diameter. It features a powerful 14HP Briggs & Stratton 4-stroke gas engine with electric start, designed for high-volume chipping and shredding.

- Always operate according to directions outlined in this user manual.
- Always wear appropriate hand and eye protection, including safety glasses, hearing protection, and heavy-duty gloves.
- Keep all bystanders, children, and pets at a safe distance (at least 50 feet) from the operating area.
- Ensure the machine is on a stable, level surface before starting.
- Never operate the chipper in wet conditions or on slippery surfaces.
- Do not wear loose clothing, jewelry, or anything that could get caught in moving parts.
- Before performing any maintenance or clearing jams, always turn off the engine and disconnect the spark plug wire.
- Familiarize yourself with the emergency stop button location and function.

2. Setup and Assembly
The Wallemac WCP15B requires some assembly before initial use. It is recommended that two people assist with assembly due to the machine's weight and size.
2.1 Unpacking and Inspection
- Carefully remove all components from the packaging.
- Inspect all parts for any shipping damage. Contact customer support immediately if any damage is found.
- Verify all parts listed in the packing list are present.
2.2 Assembly Steps
- Attach the wheels and axle assembly. Ensure all fasteners are securely tightened.
- Mount the tow hitch assembly. The 2-inch coupler hitch allows for easy towing.
- Install the feeding chute cover and extender. These components are crucial for operator safety.
- Connect the discharge chute. Ensure it is securely fastened and can be rotated for accurate debris delivery.
- For electric start models, connect the battery as per the engine manufacturer's instructions.

3. Operating Instructions
Before starting, ensure the machine is properly assembled, all safety guards are in place, and you have read and understood all safety warnings.
3.1 Pre-Operation Checklist
- Check engine oil level.
- Fill the fuel tank with fresh, unleaded gasoline.
- Inspect blades for sharpness and damage.
- Ensure all bolts and fasteners are tight. Vibration can loosen components during operation.
- Clear the work area of any obstacles or debris.
3.2 Starting the Engine
- Ensure the fuel valve is open and the choke is set appropriately for a cold or warm engine.
- For electric start models: Turn the ignition key to the "START" position. Release when the engine starts.
- For recoil start models: Pull the recoil starter handle firmly until the engine starts.
- Once the engine starts, gradually move the choke to the "RUN" position.
- Allow the engine to warm up for a few minutes before engaging the chipper.

3.3 Chipping Operation
- Feed branches into the intake chute one at a time. The self-feeding design will draw material in.
- Do not force material into the chute. Allow the chipper to work at its own pace.
- Avoid feeding material larger than 6 inches in diameter. For harder woods (e.g., oak, maple), limit diameter to 2.5-4 inches to prevent jamming or stalling.
- Use the discharge chute's rotatable feature to direct wood chips where desired.
- If the chipper bogs down or stalls, immediately stop feeding material and allow the engine to recover. If it stalls, turn off the engine and clear any jams.

3.4 Stopping the Engine
- Allow the engine to idle for a few minutes to cool down.
- Turn the ignition key to the "OFF" position or move the engine switch to "OFF".
- Close the fuel valve for storage.
4. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your Wallemac wood chipper. Always turn off the engine and disconnect the spark plug wire before performing any maintenance.
4.1 Engine Maintenance
- Oil Change: Perform the first oil change after 5 hours of use (break-in period). Subsequent oil changes should be done every 25-50 hours or annually, as per the engine manufacturer's manual.
- Air Filter: Clean or replace the air filter regularly, especially when operating in dusty conditions.
- Spark Plug: Inspect and clean the spark plug annually. Replace if worn.
- Refer to the Briggs & Stratton engine manual for detailed engine maintenance procedures.
4.2 Chipper Maintenance
- Blades: Inspect the drum knives (2 rotating, 1 anvil) regularly for sharpness and damage. Replace dull or damaged blades promptly. Easily replaceable blades are a key feature.
- Belts: Check the direct belt drive (Kevlar belt) for tension and wear. Adjust or replace as needed.
- Fasteners: Regularly check and tighten all bolts, nuts, and fasteners, especially after extended use, as vibrations can cause them to loosen.
- Cleaning: Keep the chipper clean, especially the intake and discharge chutes, to prevent buildup that could impede performance.
