Detailed technical specifications for the Putzmeister SPM 500 Wetkret concrete spraying equipment.
Daily inspections, spraying-cycle care, hour-based service tasks and warning-alert actions for safe, reliable operation.
Complete before every shift and before moving the machine. Allow approximately 15–20 minutes.
Check the dipstick with the traction engine off and the machine level.
Act if: below MIN, top up. Stop and investigate milky or foaming oil.
Check the coolant reservoir on the engine side of the chassis.
Act if: below MIN, top up. Schedule a flush if coolant is discoloured or oily.
Check the 390 L tank sight glass with the arm fully stowed and support legs down.
Act if: below range, top up with the specified grade. Do not operate with milky oil.
Check the operating-panel fuel gauge and keep the tank above one quarter.
Act if: low, refuel before the shift; do not run the tank dry.
Inspect the clear bowl at the base of the fuel filter.
Act if: water is visible, drain the bowl completely before starting.
Check the 1,000 L tank sight gauge and confirm the additive matches the mix design.
Act if: low, top up. Clean crystallised residue from the outlet before use.
Remove hardened concrete and test the electric vibrator.
Act if: material remains on the S-tube or wear plate, clean it before starting.
Check the 200 L tank and briefly test the 200 bar, 15 L/min water pump.
Act if: water is low or cleaning pressure is unavailable, correct it before spraying.
Inspect telescopic sections, hoses and pins; slowly cycle rotation, inclination and nutation unloaded.
Act if: hoses are worn or bulging, pins have excess play, or movement is jerky.
Confirm the DN 40/50 nozzle bore and diffuser holes are clear.
Act if: obstructed, clean before spraying to prevent pressure spikes and an uneven pattern.
Fill the water box with clean water and slow-test the 180 mm transport cylinders.
Act if: concrete or oil appears in the water box, inspect the relevant seals.
Confirm the reservoir is full and the automatic system completes a cycle.
Act if: low or faulted, refill or repair before operating.
Check free cable-reel winding and test radio/cable controls, including emergency stop.
Act if: any function fails or the radio link drops, do not operate until repaired.
Check all four tyres for inflation, cuts, bulges and exposed cord.
Act if: damaged, replace before travelling and use the supplied pressure chart.
Check both 12 V batteries, terminals, charge state, all work lights and the horn.
Act if: terminals are loose/corroded or a light or horn fails.
Function-test both brake systems at low speed in a clear area.
Act if: the pedal is spongy, braking pulls, or the parking brake will not hold.
Inspect the FOPS/ROPS structure and mounting area; test the belt latch.
Act if: the structure is damaged or the belt is frayed/faulty, remove the machine from service.
Walk around the machine and inspect the ground, hoses and fittings.
Act if: hydraulic, fuel, water or additive is actively leaking, repair before starting.
Extend, lock and retract the protected front and rear stabiliser legs.
Act if: a leg will not lock or its cylinder seeps, do not spray until repaired.
Park level, stow the arm, secure the support legs, apply the parking brake, isolate and lock out power, relieve hydraulic pressure, disable the remote and fully depressurise the concrete line. Support the arm mechanically whenever working beneath it.
Select an interval to view the work due. Complete all shorter-interval tasks that are also due.

Red requires an immediate stop or fault correction. Amber requires attention before normal operation continues.
Action: Stop immediately. Do not force arm or leg movement; check oil level and the diagnostic screen.
Action: Stop pumping, reverse briefly to relieve pressure, then investigate the delivery line for blockage.
Action: Check additive level and pump-tube condition, then recalibrate dosing before spraying continues.
Action: Reduce load, idle the engine and check coolant level and radiator condition.
Action: Stop the engine immediately and do not restart until the oil level and cause are checked.
