OIT Basic Operation and Controls 3 — Questions and Answers
Question 1: What is the recommended travel speed for a forklift in areas where pedestrians may be present?
- 15 mph
- 10 mph
- 5 mph or walking speed (Correct answer)
- 20 mph with horn sounding
Correct answer: 5 mph or walking speed
In pedestrian areas, forklifts should travel at approximately walking speed (3–5 mph) to allow adequate stopping distance.
Question 2: If a forklift's steering feels unusually loose or unresponsive, the operator should:
- Drive slower to compensate
- Report it and remove the truck from service (Correct answer)
- Apply extra hydraulic fluid
- Adjust the seat position for better control
Correct answer: Report it and remove the truck from service
Loose or unresponsive steering is a safety defect that requires the truck to be taken out of service and reported to a supervisor.
Question 3: The maximum fork height for traveling with a load on level ground is:
- 6 inches (150 mm) above the floor (Correct answer)
- 12 inches above the floor
- At the operator's eye level
- Fully raised for clearance
Correct answer: 6 inches (150 mm) above the floor
Loads should be carried 6 inches (150 mm) above the floor to maintain stability and adequate clearance without raising the center of gravity.
Question 4: Which of the following actions can cause a rear-wheel-steered forklift to tip sideways?
- Driving straight at low speed with no load
- Turning sharply at excessive speed (Correct answer)
- Traveling on a flat, dry concrete surface
- Fully lowering the mast before turning
Correct answer: Turning sharply at excessive speed
Sharp turns at high speeds cause lateral forces that can exceed the forklift's stability limits, leading to a side tip.
Question 5: What does a red light on the battery discharge indicator of an electric forklift typically indicate?
- Battery is fully charged
- Battery has reached 20% or less and requires charging soon (Correct answer)
- The battery cooling fan is on
- Normal operating range
Correct answer: Battery has reached 20% or less and requires charging soon
A red indicator on the discharge gauge warns the operator that battery charge is critically low and the truck should be taken for recharging.
Question 6: When picking up a load from a rack, the operator should align the forks with the pallet and then:
- Tilt the mast backward before entering the pallet
- Drive forward quickly to slide under the pallet
- Level the forks, drive slowly forward until fully under the pallet, then lift (Correct answer)
- Raise the forks above the pallet height, then drive in
Correct answer: Level the forks, drive slowly forward until fully under the pallet, then lift
Leveling the forks ensures even load engagement; slow approach and full fork insertion prevent tipping the rack or damaging the load.
Question 7: Which control is used to raise and lower the forks on a standard forklift?
- Tilt lever
- Side-shift lever
- Lift lever (Correct answer)
- Inching pedal
Correct answer: Lift lever
The lift lever controls the hydraulic cylinder that raises and lowers the fork carriage along the mast.
