Putzmeister BSF 42-5 Maintenance Checklist

Daily inspections, hour-based service tasks and display-alert actions for safe, reliable concrete pumping.

Daily Pre-Start Inspection

Complete before every shift and after any extended shutdown.

Every shift
1

Hydraulic oil

Fold the boom, retract the outriggers and read the tank sight gauge. Check oil colour and odour.

Act if: below minimum, milky, dark or burnt-smelling. Do not pump until corrected.

2

External hydraulic leaks

Inspect the pedestal, drive cylinders, swing drive, outriggers, boom cylinders and hoses.

Act if: oil seepage, spray or pooling is found. Never search for pinhole leaks by hand.

3

Water tank and flushing pump

Fill the 500 L tank and confirm the flushing pump primes and holds pressure through the hose and gun.

Act if: the tank is empty or the pump will not prime. Correct before pumping.

4

Water box and delivery pistons

Check water level, piston condition and the chrome-plated delivery-cylinder bores for scoring or grout.

Act if: grey slurry appears in the water box; inspect and replace worn piston cups.

5

S-transfer tube wear parts

Isolate the machine and inspect the S 2318LS tube, wear ring, thrust ring and spectacle plate.

Act if: there is step wear, grout blow-by or an enlarged sealing gap.

6

Hopper grate safety cutout

Clean and latch the hopper grate, then lift it slightly to test the RFID agitator and pump cutout.

Act if: the agitator or pump does not stop. Remove the machine from service.

7

Agitator and hopper seals

Run the agitator in both directions and inspect paddles, shaft seals and the hopper rubber collar.

Act if: the shaft binds, paddles are worn or grease escapes from a seal.

8

Automatic and manual greasing

Confirm both central-lubrication systems cycle and grease all remaining points shown on the lubrication plate.

Act if: a reservoir is empty or any point, especially the slewing ring, is dry.

9

Delivery line and end hose

Inspect DN 125 pipework, bends, clamps, safety locks, end hose and retaining chain.

Act if: a pipe is thin, a clamp pin is missing or the hose is damaged.

10

Boom structure and pins

Inspect all five boom sections, welds, pins, retainers, bearings, rails and the non-skid deck.

Act if: a crack, missing retainer or excessive pin play is found.

11

Outriggers and support plates

Cycle the front telescoping and rear swinging legs; verify locks and support-plate condition.

Act if: a leg creeps, a lock fails or a support plate is missing or damaged.

12

Ground and support mode

Assess bearing capacity, excavations and overhead clearance; match the Ergonic support mode to the set-up.

Act if: the ground is unstable or the displayed support mode is incorrect.

13

Ergonic display and faults

Power up the Ergonic Graphic Display and review active and stored messages before work.

Act if: an active fault appears or the display remains blank.

14

Radio and cable remotes

Test boom and pump controls on both remotes and sound the hopper-mounted horn.

Act if: either remote is unresponsive or the horn does not sound.

15

Emergency-stop circuits

Test every E-stop at the remote, control cabinet and hopper; confirm pump and agitator stop.

Act if: any E-stop fails. Stop all work until repaired.

16

Oil cooler and temperature

Check cooler cleanliness and confirm the electric fan operates.

Act if: the matrix is blocked or the fan does not run.

17

Slewing gear and bearing

Check gearbox oil, listen during slow rotation and look for grease purge at the bearing seal.

Act if: rotation is noisy or jerky, or no grease purge is visible.

18

Deck and access

Remove loose tools and pipe; inspect rear steps, rails, grab points and the non-skid platform.

Act if: the deck is obstructed or access equipment is damaged.

19

Truck chassis walk-around

Check engine oil, coolant, fuel, air pressure, tyres, wheel nuts and PTO engagement.

Act if: any chassis or PTO defect is found. Do not drive or set up until corrected.

CHASSIS PLAN

Display Symbols and Fault Actions

Red requires an immediate stop or fault correction. Amber requires attention before normal operation continues.

Red — Stop or rectify Amber — Check condition
RED

General fault

Action: Open the HOME and Pump Status menus, identify the specific symbol or stoppage code and correct it before resuming.

RED

Agitator safety cutout

Action: Clear the hopper area, close and latch the grate, and never bypass the cutout.

RED

Emergency stop active

Action: Establish why it was pressed, make the area safe and reset it only at the activated location.

AMBER

Water-pump dry-running cutout

Action: Refill the water tank before flushing or washing. Do not use an override during normal operation.

RED

Central lubrication fault

Action: Refill the reservoir or repair the system before continuing operation.

RED

Level control fault

Action: Repair the hopper level-control fault; automatic pump switching cannot be relied upon.

AMBER

Hopper full or empty

Action: Load or draw down concrete as indicated. Investigate if automatic switching behaves incorrectly.

AMBER → RED

Return-filter contamination

Action: Monitor the rising level; at red, stop and replace the element immediately because the bypass opens.

RED

Filter pressure-sensor fault

Action: Arrange service and do not rely on the contamination display until repaired.

RED

Support-system fault

Action: Stop set-up, note the fault number and repair the monitoring system before unfolding the boom.

AMBER

Engine-speed signal loss

Action: Check the engine and speed sensor. Emergency operation disables automatic output control.

AMBER

Transfer-tube resolver fault

Action: Use emergency operation only when necessary and arrange sensor repair.

AMBER

Drive-cylinder magnetic switch fault

Action: Continue only with restricted emergency controls and repair promptly.

RED

Hydraulic fluid overheating

Action: At 85°C or above, output is limited to 20%. Allow the machine to cool, inspect cooler and fans, and do not override the reduction.

RED

Pump-stoppage code

Action: Correct the displayed cause before restarting: 1 cutout, 2 E-stop, 4 pump stop, 8 engine speed, 16 lower-level sensor, 32 lubrication, 64 temperature, 128 external stop, 256 short circuit, 512 transfer-tube sensor, 1024 pressure sensor, 2048 gate valve or 4096 stroke count.

AMBER

Process monitoring mode

Action: Note the remaining operating hours and arrange support-system service before the limit expires.

AMBER

Additional support required

Action: Follow the displayed additional-support procedure before unfolding or pumping.

AMBER

Main-pump pressure-sensor fault

Action: Output is automatically limited to 50%. Operate only at reduced output and arrange sensor repair.

AMBER

Output-current monitoring fault

Action: Note outlet 17, 18, 19 or 20 and arrange repair of the identified pump or transfer-tube circuit.

RED

Lower hopper-level sensor fault

Frequently Asked Questions

Everything you need to know about the Putzmeister BSF 42-5 truck-mounted concrete boom pump

It offers a 41.6 m vertical reach, 37.3 m horizontal reach and 31 m reach depth from a five-section M42-5 boom that uses Roll-and-Z (RZ) folding.

The BSF 42.10H pump delivers a theoretical maximum output of 95 m³/h at a delivery pressure of up to 82 bar (MB 6900), with a 230 mm delivery cylinder and 27 strokes per minute.

The five-arm boom uses Roll-and-Z (RZ) folding with an 8.6 m unfolding height and 365° slewing. It runs on Free Flow Hydraulics (FFH-EL) with the Ergonic 3 control system, a 9.7″ graphic display and radio remote control.

No. The BSF 42-5 is mounted on a truck chassis, so overall dimensions, weight and engine power depend on the selected truck model. The support legs provide up to 215 kN (front) and 225 kN (rear).
