A telehandler that won't start can bring your job site to a standstill. The problem may be as simple as a weak battery or as complex as an electrical or fuel system failure. Before assuming the worst, perform a few basic inspections to help identify the cause.
Common Causes
What to Inspect First
Before calling for service, check these basic items:
When to Stop Operating the Machine
Do not continue attempting to start the engine if:
Repeated starting attempts can drain the battery, overheat the starter, and make diagnosing the original problem more difficult.
🔧 Ready Go Technician Tip
Many no-start complaints are caused by low battery voltage or poor electrical connections—not major engine failures. Always verify battery condition and cable connections before replacing expensive components. On modern telehandlers, even slightly low system voltage can prevent the engine control module from allowing the machine to start.
When to Call a Professional
If you've verified the battery, fuel supply, fuses, and basic electrical connections but the telehandler still won't start, the problem may require electronic diagnostics, fuel pressure testing, or advanced electrical troubleshooting. Modern telehandlers rely on multiple safety systems and electronic controls that often require specialized diagnostic equipment to accurately identify the fault. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
A telehandler that starts normally but won't move can quickly bring your project to a halt. The problem may be caused by something as simple as an engaged parking brake or as complex as a transmission or hydraulic drive system failure. Before assuming major repairs are needed, perform a few basic inspections to help identify the cause.
Common Causes
What to Inspect First
Before requesting service, check these basic items:
When to Stop Operating the Machine
Stop operating the telehandler if:
Continuing to operate a telehandler with drivetrain or hydraulic problems can result in significantly more expensive repairs.
🔧 Ready Go Technician Tip
If the engine revs normally but the telehandler barely moves—or doesn't move at all—the problem is often related to the hydraulic drive system or transmission rather than the engine itself. Paying attention to whether the engine responds normally while the machine fails to travel is an important clue that helps technicians narrow down the cause.
When to Call a Professional
If the parking brake, fluid levels, controls, and basic inspections all appear normal but the telehandler still won't move, professional diagnosis is recommended. Modern telehandlers use complex hydraulic, electronic, and transmission control systems that often require pressure testing and electronic diagnostics to accurately identify the source of the problem. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
A telehandler with weak hydraulic power may struggle to lift loads, raise the boom, extend the boom, or operate attachments efficiently. Hydraulic power loss can develop gradually over time or occur suddenly due to a component failure. Identifying the problem early can help prevent more extensive damage and costly downtime.
Common Causes
What to Inspect First
Before scheduling service, perform these basic inspections:
When to Stop Operating the Machine
Stop operating the telehandler immediately if:
Continuing to operate a telehandler with low hydraulic pressure can damage pumps, valves, cylinders, and other expensive hydraulic components.
🔧 Ready Go Technician Tip
One of the first questions our technicians ask is, "Are all hydraulic functions slow, or is it only one?" If every hydraulic function has lost power, the problem often points toward the hydraulic pump, oil supply, or system pressure. If only one function is affected, the issue is more likely isolated to a specific cylinder, valve, hose, or control circuit. That simple observation can significantly narrow the diagnostic process.
When to Call a Professional
If you've confirmed the hydraulic oil level is correct, there are no obvious leaks, and the machine still has weak hydraulic performance, professional diagnosis is recommended. Accurately identifying hydraulic power loss often requires hydraulic pressure testing, flow testing, and electronic diagnostics using specialized equipment. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
A telehandler boom that won't raise can stop work immediately and create a safety concern. The problem may be caused by low hydraulic pressure, a faulty control valve, a damaged lift cylinder, or an issue with the machine's safety systems. Before assuming a major hydraulic failure, perform a few basic inspections to help narrow down the cause.
Common Causes
What to Inspect First
Before requesting service, perform these basic inspections:
When to Stop Operating the Machine
Stop operating the telehandler immediately if:
Operating a telehandler with an unstable or malfunctioning boom can create a serious safety hazard for both the operator and nearby workers.
🔧 Ready Go Technician Tip
One of the first things our technicians determine is whether the hydraulic pump is actually working. If the engine loads down when you try to raise the boom, the pump is likely producing hydraulic flow, which may point toward a cylinder, valve, or control issue. If the engine doesn't respond at all, the problem may involve the hydraulic supply, controls, or an electronic safety system. That simple observation helps narrow the diagnostic process before any components are removed.
When to Call a Professional
If the hydraulic oil level is correct, no obvious leaks are found, and the boom still won't raise, professional diagnosis is recommended. Modern telehandlers use hydraulic, electrical, and electronic safety systems that often require hydraulic pressure testing and computerized diagnostics to accurately identify the root cause of the problem. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
A telehandler boom that won't extend or retract can significantly limit the machine's reach and productivity. The problem may be caused by a hydraulic issue, a damaged cylinder, worn boom components, or an electronic safety system. Before assuming major repairs are required, perform a few basic inspections to help identify the source of the problem.
Common Causes
What to Inspect First
Before requesting service, perform these basic inspections:
When to Stop Operating the Machine
Stop operating the telehandler immediately if:
Continuing to operate the machine under these conditions may result in additional damage to the boom assembly or hydraulic system.
🔧 Ready Go Technician Tip
One of the first questions our technicians ask is, "Can the boom raise and lower normally?" If the boom lifts without a problem but will not extend or retract, the hydraulic pump is often doing its job. That helps narrow the diagnosis toward the extension cylinder, hydraulic control valve, boom hoses, extension chains, wear pads, or the electronic controls specific to the telescope function.
When to Call a Professional
If the hydraulic oil level is correct, no obvious leaks are found, and the boom still won't extend or retract, professional diagnosis is recommended. Boom extension systems are more complex than they appear and often require hydraulic pressure testing, electronic diagnostics, and careful inspection of internal boom components. Identifying the root cause early can help prevent more extensive and costly repairs. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
Hydraulic oil leaks are one of the most common problems affecting telehandlers. Even a small leak can reduce hydraulic performance, create safety hazards, contaminate the job site, and eventually lead to costly component failure. Finding and repairing hydraulic leaks early can help prevent more extensive damage and unnecessary downtime.
Common Causes
What to Inspect First
Before requesting service, perform these basic inspections:
When to Stop Operating the Machine
Stop operating the telehandler immediately if:
Continuing to operate with a significant hydraulic leak can lead to pump damage, loss of hydraulic control, environmental contamination, and expensive repairs.
🔧 Ready Go Technician Tip
One of the first things our technicians ask is, "Is the leak only when the machine is running, or does it leak while parked?" A leak that only appears while hydraulic functions are being used often points toward a pressurized hose, fitting, valve, or cylinder. A leak that continues while the machine is shut down may indicate a damaged cylinder seal, residual pressure leak, or a fitting that has gradually loosened over time. That simple observation often helps narrow down the source before any components are disassembled.
When to Call a Professional
If you're unable to safely identify the source of the leak, or if hydraulic oil continues to escape after tightening accessible fittings, professional service is recommended. Many hydraulic leaks occur under high pressure and can be dangerous to inspect or repair without the proper equipment and training. Professional diagnosis can identify the root cause and help prevent repeat failures. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
A telehandler with hard or unresponsive steering can make the machine difficult to control and unsafe to operate. Steering problems may develop gradually or occur suddenly due to hydraulic, mechanical, or electrical issues. Before assuming a major steering component has failed, perform a few basic inspections to help identify the cause.
Common Causes
What to Inspect First
Before requesting service, perform these basic inspections:
When to Stop Operating the Machine
Stop operating the telehandler immediately if:
Loss of steering control can create a serious safety hazard for the operator and everyone working nearby.
🔧 Ready Go Technician Tip
One of the first things our technicians determine is whether the steering is hard all the time or only at low engine RPM. If steering improves noticeably when the engine speed is increased, it may indicate low hydraulic flow caused by a worn steering pump, low hydraulic oil, or another hydraulic supply issue. If steering remains hard regardless of engine speed, the problem may be related to the steering control unit, steering cylinder, mechanical linkage, or another component within the steering system.
When to Call a Professional
If the hydraulic oil level is correct, there are no obvious leaks, and the steering remains difficult or unpredictable, professional diagnosis is recommended. Steering systems combine hydraulic and mechanical components that often require hydraulic pressure testing and careful inspection to accurately identify the source of the problem. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
An overheating telehandler can lead to reduced performance, unexpected shutdowns, and serious engine or hydraulic system damage if not addressed promptly. Overheating may be caused by restricted airflow, cooling system problems, or excessive hydraulic temperatures. Performing a few basic inspections can often help identify the source of the problem before major damage occurs.
Common Causes
What to Inspect First
Before requesting service, perform these basic inspections:
When to Stop Operating the Machine
Stop operating the telehandler immediately if:
Continuing to operate an overheating telehandler can result in severe engine damage, warped cylinder heads, failed head gaskets, or costly hydraulic component failures.
🔧 Ready Go Technician Tip
One of the first things our technicians determine is whether the engine is overheating, the hydraulic system is overheating, or both. If the engine temperature rises but the hydraulics continue operating normally, the problem is often within the engine cooling system. If hydraulic functions become noticeably slower as the machine heats up, the hydraulic oil may be overheating due to restricted cooling, contaminated oil, or a hydraulic system problem. That distinction helps narrow the diagnosis before testing begins.
When to Call a Professional
If the coolant level is correct, the radiator and coolers are clean, and the telehandler continues to overheat, professional diagnosis is recommended. Identifying the root cause may require cooling system pressure testing, hydraulic temperature testing, electronic diagnostics, and inspection of components such as the thermostat, water pump, fan drive, and hydraulic cooling system. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
Telehandler stabilizers, also called outriggers on some models, help provide a stable foundation when lifting heavy loads. If the stabilizers won't extend, retract, or support the machine properly, the problem may involve the hydraulic system, electrical controls, or the machine's safety features. Before assuming a major component has failed, perform a few basic inspections to help identify the cause.
Common Causes
What to Inspect First
Before requesting service, perform these basic inspections:
When to Stop Operating the Machine
Stop operating the telehandler immediately if:
Operating a telehandler with malfunctioning stabilizers can compromise machine stability and significantly increase the risk of a tip-over during lifting operations.
🔧 Ready Go Technician Tip
One of the first things our technicians determine is whether both stabilizers have stopped working or only one. If neither stabilizer operates, the problem often points toward the hydraulic supply, control valve, electrical controls, or a safety interlock. If only one stabilizer is affected, the issue is more likely isolated to a cylinder, hydraulic hose, solenoid, or mechanical component on that side. That simple observation helps narrow the diagnosis before any parts are removed.
When to Call a Professional
If the hydraulic oil level is correct, no obvious leaks or mechanical damage are found, and the stabilizers still won't operate properly, professional diagnosis is recommended. Stabilizer systems combine hydraulic, electrical, and safety components that often require pressure testing and electronic diagnostics to accurately identify the source of the problem. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
Unusual noises are often one of the first signs that something is wrong with a telehandler. Whining, grinding, knocking, popping, or squealing sounds can indicate problems with the hydraulic system, drivetrain, engine, or other critical components. Identifying unusual noises early can help prevent more extensive damage and costly repairs.
Common Causes
What to Inspect First
Before requesting service, perform these basic inspections:
When to Stop Operating the Machine
Stop operating the telehandler immediately if:
Ignoring abnormal noises can allow minor problems to become major component failures.
🔧 Ready Go Technician Tip
One of the first questions our technicians ask is, "When do you hear the noise?" A noise that occurs only while operating the boom often points toward the hydraulic system or boom components. A noise that's present while driving may indicate a drivetrain, axle, or wheel bearing problem. If the noise changes with engine RPM while the machine is sitting still, technicians often begin by inspecting the engine or engine-driven accessories. Knowing when the noise occurs is one of the fastest ways to narrow down the diagnosis.
When to Call a Professional
If you're unable to identify the source of the noise or the sound becomes louder, more frequent, or is accompanied by warning lights, professional diagnosis is recommended. Unusual noises often indicate developing mechanical or hydraulic problems that are much less expensive to repair when caught early. Prompt diagnosis can help prevent additional damage, reduce downtime, and get your telehandler back to work safely.
