| Heavy-duty torque wrench | Applying specified torque to wheel fasteners and other service fasteners. | Torque range, drive size, accuracy statement, scale readability, and calibration interval. | Request a calibration certificate traceable to recognized standards and confirm the stated accuracy across the working range. | Choose a range that covers the procedures performed; use the vehicle or component maker’s torque specifications. |
| Pneumatic or cordless impact wrench | Removing stubborn fasteners and carrying out high-volume disassembly work. | Drive size, working torque, air pressure and air consumption (pneumatic), battery voltage and runtime (cordless), and tool weight. | Check rated performance conditions, duty-cycle guidance, spare-part availability, and warranty terms. | Match a pneumatic tool to the compressor and hose capacity. Do not use an impact wrench as a substitute for final torque verification. |
| Commercial-vehicle diagnostic scanner | Reading and clearing fault codes, viewing live data, and performing supported service functions. | Supported vehicle systems, protocol coverage, connector compatibility, software update policy, and language options. | Request a current coverage list and written confirmation for the truck makes, models, and systems in your fleet. | Verify coverage before purchase. “Truck compatible” does not necessarily mean every control unit or special function is supported. |
| Hydraulic floor jack or bottle jack | Lifting a vehicle or component at approved lifting points during service. | Rated capacity, minimum and maximum lift height, saddle dimensions, and operating instructions. | Inspect the rating plate, hydraulic components, welds, and documentation; check for leakage and smooth operation before use. | Select capacity and lift range for the specific vehicle and lifting point. A jack is for lifting, not for supporting a vehicle while work is performed. |
| Heavy-duty axle stands | Supporting a raised vehicle after lifting, where the vehicle maker permits. | Rated capacity per stand or pair, height range, locking mechanism, base footprint, and intended use. | Check clear capacity markings, secure locking pins or ratchets, stable bases, and inspection instructions. | Confirm whether the rating applies to each stand or a pair; use stands on firm, level ground and follow safe-work procedures. |
| Air compressor and air preparation equipment | Supplying pneumatic tools, tyre-service equipment, and other air-powered workshop devices. | Delivered air flow at working pressure, tank volume, duty cycle, electrical supply, filtration, and moisture control. | Compare flow ratings at the stated pressure, pressure-vessel documentation, maintenance requirements, and local electrical compatibility. | Size the system for simultaneous tool demand and pipe losses; tank volume alone does not show how much air the compressor can deliver. |
| Digital multimeter and electrical test leads | Checking voltage, resistance, continuity, and other electrical values within the meter’s rated functions. | Measurement ranges, accuracy, input protection, safety category, fuse ratings, and lead compatibility. | Check the safety markings and manual, and confirm that meter and leads are suitable for the measurement environment. | Use a meter with suitable ratings for the circuit being tested. Do not exceed the instrument’s voltage or current limits. |
| Brake-service tools | Supporting brake inspection and service, such as piston retraction or bleeding, when appropriate for the brake design. | Included adapters, compatibility with the brake system, operating method, and any pressure or fluid requirements. | Request clear instructions and an application list; check materials for compatibility with the specified brake fluid. | Confirm the tool suits the vehicle’s brake arrangement. Follow the service procedure and fluid specification for that vehicle. |
| Wheel-service tools and sockets | Removing and installing wheel fasteners and handling wheels during tyre or brake work. | Socket size and profile, impact rating, drive size, material and heat-treatment information, and wheel-handling capacity where applicable. | Check dimensions, impact-use markings, finish quality, and replacement availability for wear-prone parts. | Use impact-rated sockets with impact tools and the correct socket profile for the fastener; inspect sockets for cracks and wear. |
