NCCCO Telehandler common mistakes
NCCCO Telehandler · Understand the traps and how to avoid them.
Walking the machine but only checking fluid levels and tire pressure, then declaring the inspection complete without testing the horn, backup alarm, lights, or parking brake, or checking the load chart and capacity plate are legible and present in the cab.
Candidates treat the walk-around as a fluid check because that is what they do daily on a pickup truck, and they underestimate how heavily the practical exam weights functional safety devices and required decals.
What to do instead
Use a fixed, memorized sequence: fluids and leaks first, then tires and wheels, then boom, chains, and hoses, then operator station, then every safety device operated one at a time (horn, backup alarm, lights, parking brake, level indicator). Finish by confirming the load chart, capacity plate, and required decals are present and readable. Say each item aloud as you check it.
Failing to inspect the boom wear pads, extend chains, and hydraulic hoses for chafing, leaks, or debris, and skipping the confirmation that the machine is level before raising the boom.
These components are visually less obvious than tires and are easy to skip under time pressure, and candidates do not connect worn wear pads or a leaking hose to a boom that drifts or binds during the lift.
What to do instead
Add a dedicated boom pass to the walk-around: check wear pads for excessive gap or scoring, inspect extend chains for tension and damage, run a hand along hoses looking for chafe points and wet spots, and confirm the frame level indicator reads level on the machine before any boom raise.
Reading the load chart only at the pick point and ignoring how capacity changes as the boom is extended, lowered, or swung, and treating the chart as a single number rather than a zone-based limit.
Candidates memorize one capacity figure for the machine and do not internalize that telehandler capacity falls steeply with radius and boom extension, so they believe the chart is a formality.
What to do instead
Before every lift, locate the actual load weight, then find the intersection of radius and boom angle or extension on the chart and confirm the capacity exceeds the load plus rigging. Recheck the chart at the worst-case point of the planned travel path, not just at the pick. Practice reading charts at several radii until the pattern is automatic.
Estimating the load weight from appearance or accepting the shipper's verbal figure instead of obtaining a documented weight, and forgetting to add the weight of slings, spreader bars, and the attachment.
Candidates want to keep the job moving and assume a pallet or bundle is a standard weight, and they mentally separate the rigging from the load even though the chart does not.
What to do instead
Require a shipping document, label, or scale ticket for every load, and write the total (load plus rigging plus attachment) on the lift plan. If no weight can be confirmed, treat the lift as unplanned and do not proceed. On the exam, state the total weight and the rigging allowance explicitly.
Choosing a travel path without checking ground bearing, slope, overhead power lines, and pedestrian traffic, then discovering soft fill, a cross-slope, or a low wire only after the load is in the air.
Candidates focus on the pick and set points and treat the route between them as empty space, and they underestimate how quickly a telehandler becomes unstable on soft or sloping ground.
What to do instead
Walk the full route before the lift. Note surface type and condition, any soft spots or trench plates, slope in both directions, overhead obstructions and line voltages, and pedestrian or vehicle traffic. Mark the route and record the findings on the lift plan, then set the machine up level with outriggers or stabilizers deployed as the manufacturer requires.
Skipping or misapplying the pre-lift plan: no documented lift plan, no verification that the attachment is properly engaged and the quick-coupler locked, and no communication plan with the signal person.
Candidates see the plan as paperwork that exists only for critical lifts, and they assume the attachment is secure because it was installed earlier by someone else.
What to do instead
Treat every lift as planned: identify the load, the attachment, the capacity, the route, the set point, and the signal person. Physically verify the quick-coupler is fully engaged and the locking pin or lever is in the locked position, then test the attachment at low height before the lift. Agree on hand signals and the stop command before the boom moves.
Raising or extending the boom while the machine is on a slope or with the frame out of level, or traveling with the boom elevated and the load high instead of keeping it low and the machine level.
Candidates carry over habits from forklifts, where the mast is short and travel with an elevated load feels normal, and they do not feel the stability change until the machine is already tipping.
What to do instead
Establish the rule as a hard sequence: level the machine, deploy stabilizers if equipped, then raise. Keep the boom retracted and the load low for travel, and never travel with a raised boom on uneven ground. Re-level after every reposition, and treat the level indicator as a go/no-go check.
Misjudging stopping distance and turn radius under load, cornering too fast, and using the service brake as the primary way to stop on a grade instead of controlling speed before the hazard.
Telehandlers are heavy and rear-wheel steer, so they behave very differently from a car or a counterbalance forklift, and candidates do not practice loaded braking or tight turns.
What to do instead
Practice loaded stops and turns in a controlled area until the machine's response is familiar. On the job, reduce speed before corners and grades, keep the load low, use engine braking or dynamic braking as the machine provides, and allow extra distance for the increased stopping distance of a loaded machine.
Failing to look up and behind during boom raise and travel, hitting overhead structures, power lines, or a pedestrian in the rear-steer blind spot, and not using a spotter when visibility is restricted.
The operator's attention is on the load and the set point, and the rear-wheel steering geometry creates a swing path that candidates do not anticipate.
What to do instead
Before raising, scan overhead for wires, beams, and door headers, and maintain the required minimum approach distance to power lines. Use a signal person whenever the load or the rear swing path is not fully visible, and confirm eye contact or radio contact before moving. Check mirrors and the rear area before every reverse.
Parking the machine with the boom raised or the attachment off the ground, leaving the key in the ignition, and not applying the parking brake or lowering the attachment to the ground before shutdown.
Candidates finish the lift task and mentally check out, and they do not treat secure shutdown as part of the operating standard.
What to do instead
Follow a fixed shutdown sequence: lower the boom and set the attachment flat on the ground, retract the boom, apply the parking brake, place controls in neutral, shut down, remove the key, and secure the machine. State each step on the exam so the evaluator can see the sequence is deliberate.
