Safety Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with the safety instructions in the traction unit operator’s manual and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death. POTENTIAL HAZARD • When the engine is off, attachments in the raised position can gradually lower.
Safety POTENTIAL HAZARD • The breaker is very loud during operation. WHAT CAN HAPPEN • Over time, your hearing may be impaired if unprotected. HOW TO AVOID THE HAZARD • Wear hearing protection during operation. Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.

Installation Loose Parts DESCRIPTION QTY. Breaker 1 Bit–concrete breaker (other bits are available; contact your Toro dealer for more information) 1 IMPORTANT: The Hydraulic Relief kit must be installed on some traction units prior to using the breaker or serious damage may occur to the hydraulic system. Failure to install the relief kit will void the warranty of your traction unit. To determine if your traction unit needs a Hydraulic Relief Kit, contact your authorized Toro dealer.
Installation 7. Stop the engine. 8. Engage the attachment lock pins (Fig. 2). 1 1 3 4 2 m–4056 Figure 2 m–4248 Figure 3 1. Attachment lock pins (shown in engaged position) 1. Retaining pin 2. Bit Installing the Bit 3. Notch 4. Grease here 4. Remove the plastic spacer. 1. Raise the horizontal breaker so it is about 6 inches off of the ground. 5. Smear grease completely over the top six inches of the bit (Fig. 3). 2. Stop the engine and remove the key. 6. 3.
Installation Connecting the Hydraulic Hoses 1. Stop the engine. 2. Move the auxiliary hydraulics lever forward, backward, and back to neutral to relieve pressure at the hydraulic couplers. 3. 4. 5. Slide the collar back on the hydraulic couplers and disconnect them. IMPORTANT: Connect the attachment hoses together to prevent hydraulic system contamination during storage. IMPORTANT: Ensure that all foreign matter is cleaned from the hydraulic connections before making connections.
Operation Operating Tips • When breaking, always apply downward pressure with the loader arms until the front wheels raise off of the ground a few inches (Fig. 4). Maintain this pressure as the bit works its way into the material being broken. • Always use full throttle (maximum engine speed) when breaking. • Use low range (turtle position) on the speed selector for best performance and smoothest operation.
Operation 1 2 1 m–4250 Figure 5 2 IMPORTANT: Never pry with the bit. • If you are breaking rebar reinforced concrete, use a chisel bit in the breaker to cut through the rebars in the concrete. The rebar can also be cut with a torch. IMPORTANT: Do not use the breaker in or under water. Breaking a Vertical Surface Converting the Breaker 1. Tilt the breaker as far forward as possible and lower it until the tip is resting on the ground. 2. Remove the click pin securing the front mounting pin (Fig. 6).
Maintenance Service Interval Chart Each Use Storage Service Grease the bit X X Inspect and tighten all fasteners X X Inspect the mounting pins, holes, lower bushing (above the bit), bit retaining pin, and roll pins for looseness or wear. X X Reseat or replace as necessary. Check for hydraulic leaks at all fittings and hoses. X X Repair leaky fittings and/or replace leaky hoses.
Maintenance 3. Clean the grease fitting with a rag. POTENTIAL HAZARD • Hydraulic fluid escaping under pressure can penetrate skin and cause injury. WHAT CAN HAPPEN • Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result. HOW TO AVOID THE HAZARD • Keep body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid.
Troubleshooting PROBLEM The breaker does not operate. 12 POSSIBLE CAUSES CORRECTIVE ACTION 1. Hydraulic coupler not completely connected 1. Check and tighten all couplers. 2. Damaged hydraulic coupler 2. Check couplers and replace any that are damaged. 3. An obstruction in a hydraulic hose 3. Find and remove the obstruction. 4. Auxiliary valve on the traction unit is not opening. 4. Repair the valve. 5. Low nitrogen level in the breaker 5. Refer to you authorized Toro dealer.
