1. What is the primary purpose of a pre-operational inspection
on a forklift?
A. To determine the operator's productivity
B. To estimate fuel consumption
C. To identify safety defects before operation
D. To determine the machine's resale value
Rationale: A pre-operational inspection is intended to identify
defects or unsafe conditions before the equipment is placed into
service. Items such as brakes, steering, tires, forks, mast
components, hydraulic systems, warning devices, and safety
equipment should be checked. Early identification prevents
equipment damage, unsafe operation, and potential injuries.
2. Which component converts hydraulic pressure into linear
mechanical movement?
A. Hydraulic pump
B. Hydraulic cylinder
,C. Hydraulic reservoir
D. Hydraulic filter
Rationale: A hydraulic cylinder converts pressurized hydraulic
fluid into linear force and movement. In material handling
equipment, cylinders are commonly used for lifting, tilting,
steering, and other functions. The pump creates hydraulic flow,
while the cylinder uses that flow to produce mechanical
movement.
3. What is the primary function of hydraulic fluid?
A. To increase electrical resistance
B. To cool the tires
C. To transmit power and provide lubrication
D. To increase engine compression
Rationale: Hydraulic fluid transmits energy through the
hydraulic system while also providing lubrication, cooling,
corrosion protection, and contamination control. The fluid must
have the correct viscosity and cleanliness for the equipment
manufacturer’s specifications.
4. What is the most likely result of a severely clogged hydraulic
filter?
,A. Increased hydraulic flow
B. Increased battery voltage
C. Restricted flow and possible system damage
D. Improved hydraulic efficiency
Rationale: A clogged filter restricts fluid flow and can cause
pressure problems, overheating, sluggish operation, and
component damage. Depending on the system design, a bypass
valve may open when the filter becomes excessively restricted,
allowing contaminated fluid to circulate.
5. What is the purpose of a relief valve in a hydraulic system?
A. To increase maximum system pressure indefinitely
B. To protect the system from excessive pressure
C. To remove air from the fuel system
D. To increase battery charging voltage
Rationale: A relief valve limits hydraulic pressure by diverting
fluid when pressure reaches a predetermined setting. This
protects pumps, cylinders, hoses, valves, and other components
from excessive pressure and potential failure.
6. Which instrument is commonly used to measure hydraulic
pressure?
, A. Tachometer
B. Ohmmeter
C. Pressure gauge
D. Hydrometer
Rationale: A hydraulic pressure gauge measures fluid pressure
within a hydraulic circuit. Technicians use pressure
measurements during troubleshooting to compare actual
system performance with manufacturer specifications and
determine whether pumps, valves, regulators, or other
components are functioning correctly.
7. What is cavitation in a hydraulic pump?
A. Excessive electrical current
B. Excessive tire pressure
C. Formation and collapse of vapor bubbles in the fluid
D. A hydraulic filter becoming electrically grounded
Rationale: Cavitation occurs when the pump inlet does not
receive adequate fluid, causing localized low pressure and vapor
bubble formation. When these bubbles collapse, they can
produce noise, vibration, heat, and damage to pump surfaces.
Restricted suction lines, low fluid levels, or incorrect fluid
viscosity can contribute to cavitation.
