Operator panel to set brush pressure, fan speed and water flow modes.

Handheld thermometer for checking road surface temperature before spraying or marking. Ensures conditions meet specification for proper adhesion.

Heavy-duty switch isolating all electrical circuits. Used at shift end to prevent battery drain and comply with depot safety policies.

Strainer protecting nozzles and flow meters from contaminants.

Non-contact tool for quick surface/binder temperature.

Fuse protecting the auxiliary-engine start circuit from surge currents. Reduces risk of wiring fires on older sweepers.

Spill kits/cones carried for emergency response.

First absorption of binder into dry surface before chipping; affects final texture.

Electronic module automatically adjusting auxiliary-engine idle speed. Maintains optimal hydraulic pressure when sweep load changes.

Relay delaying accessory power until engine start is complete. Prevents voltage drop to controllers during cranking.
