What is the correct way to inspect forklift forks for wear?
Answer: Measure fork thickness at the heel and compare to original specifications; replace if worn more than 10%
OSHA and ASME B56.1 require measuring fork thickness at the heel; forks worn more than 10% of original thickness must be replaced.
During inspection, an operator notices that the lift chains are uneven in tension. What does this indicate?
Answer: One chain may be stretched or damaged, requiring immediate maintenance evaluation
Uneven chain tension indicates that one chain is stretched or damaged, which creates an unsafe load-carrying condition requiring maintenance.
What hazard can result from operating a forklift with a cracked or damaged load backrest extension?
Answer: Loads can shift backward and fall on the operator
A damaged load backrest extension allows loads to shift rearward toward the operator, creating a serious crush and falling-load hazard.
Which fluid should NOT be topped off by the operator and must be handled only by qualified maintenance personnel?
Answer: Both B and C
Brake fluid and pressurized coolant systems require qualified maintenance personnel due to safety risks and system-specific procedures.
A propane-powered forklift's gas cylinder shows frost on the exterior during operation. What does this indicate?
Answer: The cylinder is being used too quickly or has a regulator issue requiring inspection
Frost on an LPG cylinder during operation indicates excessive withdrawal rate or a regulator issue that must be inspected by qualified personnel.
What should an operator check when inspecting the forklift's steering system?
Answer: Excessive play in the steering wheel, smooth operation, and absence of unusual sounds
Operators must check for excessive steering wheel play, smooth directional response, and unusual sounds that indicate worn components.
When is it acceptable for a forklift operator to repair a hydraulic hose that is leaking?
Answer: Never — hydraulic repairs must be performed by qualified maintenance personnel
Hydraulic hose repairs require qualified maintenance personnel because high-pressure hydraulic fluid injection injuries are life-threatening.
