RECONNECT SPARK PLUG WIRE AND

GUARDS BEFORE STARTING ENGINE.

17.1IMPELLER REMOVAL

1. Disconnect spark plug wires.

2. Elevate front of machine using stable support blocks between housing and ground so that front wheel

is not touching ground.

3. Remove front wheel bracket and front intake plate from the housing.

4. (Self propelled models only) Remove the clutch guard from the left side of the unit between housing and engine.

5. Remove impeller bolt and lock washer.

6. (Self propelled models only) Slide belt toward engine, out of belt groove in impeller hub drive pulley.

7. If impeller slides off freely, proceed to (step 12).(Note: Do not

pull or pry on impeller blades.)(Do not drop impeller).

8.If impeller does not slide off crankshaft, place two crowbars between impeller and housing on opposite sides. Pry impeller away from engine until it loosens. Using a penetrating oil can help loosen a stuck impeller.

9.If the impeller cannot be loosened, obtain a 1” (25.4mm) longer bolt of the same diameter and thread type as the impeller bolt.

Invert engine and impeller and support engine above ground to prevent recoil damage. Thread longer bolt by hand into the crankshaft until bolt bottoms. Using a suitable gear or wheel puller against the bolt head and the impeller back-plate (near the

blades), remove impeller from shaft.

10. Slide impeller off of crank shaft and remove impeller from housing.

11. Reinstall new impeller and all applicable spacers, new impeller bolt and lockwasher in reverse order of removal. (See the parts drawing on pages 8 and 9 for parts break- down and parts list on page 10 for proper impeller bolt torque specifications.)

17.1IMPELLER REMOVAL continued

12. (Self propelled models only) When impeller is installed, slide belt into drive pulley.

13. Reattach front intake plate and front wheel bracket in reverse order of removal.

14. (Self propelled models only) Check operator's bail to ensure that it operates properly. If not, see drive adjust ments on page 14). Note: Drive must completely disengage with bail released and must engage when bail is depressed within 1.0" (25.4mm) of the operator's handle.

15. (Self propelled models only) Reinstall clutch guard.

16. Reconnect spark plug wire.

QB1601, QB1601SP specifications

The Billy Goat QB1601 and QB1601SP are advanced commercial-grade quick-attach blowers designed to deliver unmatched performance and efficiency in outdoor clean-up tasks. These models excel in managing debris in demanding environments, making them perfect for landscapers, contractors, and property maintenance teams.

At the heart of both models is a powerful 160cc engine that ensures robust performance. This engine not only provides ample power for efficient debris clearing but also operates at lower emissions levels, aligning with regulatory standards while minimizing environmental impact. The lightweight design of the QB1601 and QB1601SP models allows operators to maneuver with ease, reducing fatigue during long work hours.

One of the standout features of these blowers is their innovative air intake system. Incorporating a large, durable air filter, the QB1601 and QB1601SP are equipped to handle dust and debris, ensuring the engine runs smoothly for extended periods. The blowers also feature a unique vacuum and mulching system that allows users to switch between blowing and vacuuming modes effortlessly. This versatility significantly enhances productivity, as it enables operators to handle different tasks without needing multiple machines.

The QB1601 model is designed to offer a comfortable user experience, boasting ergonomically designed handles that reduce vibration and provide a secure grip. This thoughtful design translates to improved control and precision during operation. Moreover, the unit's compact size ensures easy storage and transport, making it a practical choice for professionals on the go.

In contrast, the QB1601SP model introduces a self-propelled feature, allowing for greater ease in operation over uneven terrains. This makes it particularly advantageous for expansive properties or areas with challenging landscapes. The self-propelled drive system provides added speed and efficiency, enabling users to cover larger areas in less time while maintaining consistent blowing power.

Both models come with a variety of nozzle attachments, allowing the user to customize airflow to suit different tasks—whether it's tackling leaves, grass clippings, or heavier debris. The adjustable airflow speed settings also give operators greater control, ensuring they can meet specific cleanup requirements effectively.

In summary, the Billy Goat QB1601 and QB1601SP are exemplary outdoor blowers that feature robust engines, innovative air intake systems, comfortable handling designs, and versatile attachments. These machines are engineered to provide high efficiency, durability, and user comfort, making them indispensable tools for any outdoor maintenance professional.
