Choosing the Right Line Marking Spray Gun
Spray guns are the second most unit-critical decision after the unit itself. Pick by what the unit is doing: paint walk-behind work uses manual airless guns, ATS 4110 longitudinal markings on public roads use automatic airless guns for Clause 6 capability, and cold applied plastic uses Fusion ProConnect for at-the-gun plural-component mixing. The right gun pairs with the right tip and the right hose, and the wrong gun on the wrong unit costs throughput and paint atomisation quality.
Manual airless guns for paint LineLazer. The Graco Flex Plus airless gun (248157, RAC 5 LineLazer fitment) is the production manual gun on the LineLazer paint unit: comfortable trigger, swivel-mounted RAC 5 SwitchTip holder, and the standard fit on every LineLazer ES, 3400 and V manual units. Flex Plus 287095 is the equivalent gun shipped as a complete kit (gun plus 6.4 mm x 15 m hose, 3,300 PSI rated, RAC X 517 HandTite guard, 0.9 m whip hose). Single-Acting 238377 covers earlier paint unit fitments.
Automatic airless guns for ATS 4110 Clause 6 capability. ATS 4110 Clause 6 mandates that longitudinal pavement marking machinery be fitted with automatic pattern control (skip-line) and dual-angle bead delivery, which means automatic guns rather than manual triggers. The Graco AL Series Automatic Airless gun (288048) and the Double-Acting paint spray gun (24G980) are the standard auto guns for council and contractor public-road work. The 2nd Automatic Gun Kit for LineLazer V 3900 / V 5900 / V 200HS (25A673) and the 2nd Gun Kit for LineLazer 130HS (25A676) add a second auto gun to existing units for double-line / barrier-line work. The V Gun Kit Range (25A491) covers the upgrade path from manual to auto on the LineLazer V family.
Fusion ProConnect for cold applied plastic (CAP/MMA). The Fusion ProConnect Gun mixes the resin and catalyst at the gun (not in a pre-mix pot) for the LineLazer V 200MMA cold applied plastic unit. The ProConnect Cartridge in 1-pack (19Y300) and 5-pack (19Y308) is the standard consumable. The MMA Cartridge (25V433), Mix Chamber (25T481), Flat Mix Chamber PC20FL (with 0.020 in / 0.51 mm orifice), and Orifice PC22WD cover the unit-side wear parts. The Fusion AP MMA Retrofit Kit (26D973) and Fusion PC MMA Gun (25U857) cover the gun-side upgrades. The MMA Air-Purge LineLazer Gun (25E471) clears the mixing chamber on shutdown to prevent cure-in-place; running MMA without Air-Purge is the single biggest cause of catastrophic gun failure on plural-component unit.
Repair kits and accessory guns. Flex Plus needle kits, packings and seal kits are the standard wear parts on the LineLazer paint family; carry the Flex Plus needle kit on the truck for any council shift longer than three days. For Fusion ProConnect and Fusion PC MMA gun rebuilds, stock the matched filters and A / B side valves alongside the ProConnect Cartridge. The LineLazer Dual Spray Kit (287626) converts a single-gun unit to dual-gun for double-line work. Match the repair kit and accessory gun to the unit serial before ordering.
