Study Notes

Forklift Concepts and Operations

The mast is the vertical structure at the front of a forklift that supports the fork assembly.
Engaging the dog differential lock requires releasing accelerator pressure until wheels stop spinning, then activating the switch.
The start position on the ignition switch is spring-loaded and returns to a neutral state when released.
An immediate alarm during boom engagement likely indicates a load stability alarm.
For maximum lifting capacity, the boom should be fully retracted and angled upwards at its highest angle.
Power hop is exacerbated by operating on soil with a firmer sub-layer beneath.
In cold weather, lubricate pivot points at the end of the shift to ensure smooth operation.
Preparing a forklift for inspection includes placing chocks under the wheels for safety.
The leading cause of fatal forklift accidents is a forklift roll over.
When traveling, the ideal fork height is maintained at 12 to 18 inches above the ground.
A forklift operator must respond immediately to any command to stop, regardless of the source.
The seat belt should be adjusted so knees are slightly bent when pedals are fully pressed.
When both front outriggers are set for lifting, the front wheels should be entirely off the ground.
The best steering mode for smooth road travel is two-wheel drive.
A forklift with forks extended 20 feet high can safely lift a maximum of 2,000 lb.
Two-wheel drive forklifts utilize front wheels for driving and rear wheels for steering.
Oblique steering allows all four wheels to turn in the same direction simultaneously.
A hydrostatic transmission provides infinitely variable speed adjustments for optimal control.
Forklifts equipped with a FNR control typically feature a hydrostatic transmission.
Boom extensions are usually adjusted manually for precise control in lifting tasks.
The lifting capacity of the FB-40 boom attachment at an 11-foot extension is 1,600 pounds.
Maintenance intervals recommended by manufacturers align with SAE standards.
Operators should expect to lower the forks as a standard communication movement.
After startup, wait 10 seconds for the oil pressure light to turn off before considering engine shutdown.
Allow the forklift to run for approximately 5 minutes post-operation to cool fluids effectively.
In slippery conditions with spinning rear wheels, engage the differential lock for improved traction.
The function of frame-leveling control is to stabilize the forklift by rotating the chassis on its axles.
If the rear wheels lift off the ground while handling a load, the operator should stop raising and carefully lower it.
