17 MAINTENANCE continued

Clear intake screens on housing and engine throughout use. Inspect machine for loose bolts before starting engine.

Lubrication: Using S.A.E. 30 weight oil or equivalent. See maintenance schedule. Chain: See SP section below.

Lower Control Ends: Oil moving parts, such as bail, and deflector door pivots.

Grease: Front wheel, and Caster(SP only).

Tire air pressure: Check at regular intervals & maintain: Low tire pressure will make unit hard to push and turn.

Front tire at 30 psi. (21.1 kPa).

Rear push 16" tires at 30 psi. (21.1 kPa). Rear SP 16" tires at 35 psi. (24.6 kPa).

Rear caster tire (SP only) at 30 psi (21.1 kPa)

17.3DRIVE

Chains and Belts are normal replaceable wear items. A new chain should not be used on worn sprockets. Sprockets should be inspected and replaced when worn.

MAINTENANCE- SP MODELS ONLY

Brake Adjustment: As parking brake wears, the brake discs may eventually require adjustment. To adjust, remove bottom guard from engine base and tighten brake adjusting nut on transmission. Adjust cable nut as required. Unit must free- wheel in neutral with clutch engaged and brake off.

DO NOT OVER ADJUST.

Chain Adjustment: (See fig. 11)

1.Remove spark plug wire.

2.Remove bottom drive guard.

3.Inspect chain and sprockets for wear, lubrication and tension. Replace if badly worn or damaged. Skip to CHAIN

REPLACEMENT

4.Check chain tension. There should be no more than 0.25" total movement when chain is flexed from top to bottom.

5.To increase chain tension, loosen, do not remove, the bolts that hold the bearings in place on each side and in the center of the differential.

6.Loosen, do not remove, the Jam nut that locks the bolt into the chain tensioner on each side of the differential.

7.With the bolts loose, equally tighten the chain tensioner bolt on both the left and right side of the differential.

8.Adjust in small increments, checking chain alignment, tension and axle squareness between steps. Roll wheels to check that there are no excessively tight areas in the chain. Repeat adjustment steps if necessary. A slightly loose chain is better than an over tightened one.

9.With chain properly adjusted securely tighten the jam nuts, and bearing mount bolts.

10.Reinstall drive guard.

11.Reconnect spark plug wire.

Chain Lubrication: With machine not running, oil chain using general purpose S.A.E. 30 weight oil every 25 hours or as needed. Chain oiling hole is located on operator's left at rear of engine base. Note: Be sure that entire length of chain is properly oiled. Oiling only a few positions in the chain rotation will not properly oil the chain.

Belt Adjustment: As V-belt wears, adjustments may be required to maintain proper clutch engagement. Adjust by tightening or by loosening clutch cable adjusting nut as required, located on operators left near the face of the engine (See fig. 10). When replacing belt, see BELT REPLACEMENT.

DO NOT OVER ADJUST.

Belt Replacemment:

1.Remove impeller, follow impeller removal instructions on page 13.

2.Remove six screws securing blower housing.

3.Inspect for worn or damaged pulleys. Replace if necessary.

4.Replace worn belt.

5.Replace housing. Note: Be sure to replace lock clip on upper bolts in exact manner that it was originally installed.

6.Replace impeller, refer to impeller removal instructions on page 13.

7.It may be necessary to adjust the belt engagement. See Belt Adjustment.

Chain Replacement: (See fig. 11)

1.Remove spark plug wire.

2.Remove bottom drive guard.

3.Inspect sprockets for wear. Replace if badly worn or dam- aged.

4.Release chain tension. See Chain Adjustment.

5.Remove operators right and center axle bearings.

6.Remove old chain by sliding over the axle and out the hole that the right axle bearing was mounted in.

7.Install new chain in the reverse order of removal.

8.Set chain tension. See Chain Adjustment.

9.Replace bottom drive guard.

10.Replace 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.
