Wash Machine Externally
Disconnect firefighting equipment if steam washing or high-pressure washing is used.
- 1.Rinse the machine with water at least once a day to remove drill cuttings, mud, and dirt.
The feed, front part of the boom, and track frames are important to keep clean.
Examine the Condition of Signs
Make sure that all signs are in place.
Make sure that all signs are intact, clean, and fully readable.
Always replace defective or missing signs.
Lubricate Drill Rod Support
- 1.Pump lubricant into the lubrication nipple (A).
Lubricate Hydraulic Drill Rod Support
This equipment is optional.
- 1.Pump lubricant into the lubrication nipples (A).
Check Feed When Drilling Upwards
- 1.Pump lubricant into the grease nipples (A).
- 2.Clean the slide bars (B).
Check Lubrication Tank Level
NOTE
Bleeding of the lubrication system is necessary if all the oil is drained out of it.
- 1.Check the tank (A) and connections for signs of leakage.
- 2.Fill up to the high-level mark.
Check Fire Extinguishers
- 1.Check that the indicator is in the green zone. Replace the fire extinguisher if the indicator is in the red zone.
- 2.Check the seals for damage. Replace the seals if necessary.
- 3.Check the fire extinguisher body and holder for damage. Replace the fire extinguisher if necessary.
NOTE
Follow the instructions on the handheld fire extinguisher for further maintenance.
Check Emergency Stops and Work Lights
Precondition
The diesel engine must be off.
- 1.Check that no warning lamp comes on, on the diesel panel (A).
- 2.Check functionality of the front and rear work lights (B).
- 3.Check each emergency stop button (C) individually. The previous emergency stop must be reset before checking the next one.
Check Coolant Level
WARNING
Moving Parts
Can cause serious personal injury
Set all levers and switches in NEUTRAL position before startup preparations.
Carry out the procedures with the engine switched off.
WARNING
High-Pressure Cleaning
High-Pressure Cleaning using compressed air, water jets, or steam jets can cause personal injury.
Make sure that appropriate protective clothing is worn to protect eyes and exposed parts of the body.
Maximum air pressure at the nozzle must be less than 205 kPa (30 psi) for cleaning purposes.
Precondition
The coolant level must be checked when the diesel engine is cold.
NOTE
Apart from elements for engine coolant the radiator also has elements for cooling hydraulic oil, compressor oil, and charge air.
- 1.Loosen the radiator cap (A) to the stop position, release the pressure in the cooling system and only then remove the radiator cap. The expansion tank is on the roof of the machine.
- 2.Check the coolant level (B).
- 3.Top up as necessary.
Check Hydraulic Oil Level
Precondition
All the cylinders are retraced.
The machine must be horizontal to give a correct reading.
- 1.Check the level of the hydraulic oil (A). Add hydraulic oil as necessary.
Add hydraulic oil as necessary.
NOTE
The oil level must not be in the red zone.
- 2.Check for oil leaks at the tank and pumps.
Check Hydraulic Oil Filter
- 1.Replace the hydraulic oil filter (A) if the needle on the pressure gauge (B) for the return oil is in the red zone.
- 2.Check the connections on the hydraulic tank for signs of leakage.
Check Engine Oil Level
WARNING
Hot Surface
Hot components can cause serious personal injury.
Turn off the machine and allow the components to cool down before starting maintenance work.
Use Personal Protective Equipment (PPE).
Be careful when draining hot fluids.
Do not handle flammable fluids near hot surfaces, sparks, or open flames.
WARNING
Burning Hazard
High oil temperature can cause serious personal injury.
Shut off the engine.
Use working gloves, face shield, and cover your arms with long sleeves.
Precondition
The diesel engine is turned off.
- 1.Check that the oil level is between the upper and lower mark on the dipstick (B).
- 2.Top up the oil through the filler cap (A), if necessary.
NOTE
Only use engine oil that the engine manufacturer approves for engine and type of operation.

Check Compressor Oil Level
Precondition
The machine is parked on a flat and level surface.
- 1.Stop the machine and allow the oil level to settle for at least 5 minutes.
- 2.Check that the indicator on the gauge (A) is in the green zone.
- 3.Fill with oil through inlet (B), if necessary. Use the correct amount and oil grade.
Drain Water Condensation from Fuel Filter or Water Separator
- 1.Drain off water from the fuel filter or water separator (A).
Check Condition of Diesel Engine
- 1.Check for signs of leakage on the hydraulic oil pumps (D).
- 2.Check for leaks on the diesel engine (E).
- 3.Check for wear and tension on belts (C).
- 4.Check connections and couplings on the intake manifold on the air filters (A) for diesel engine and (B) for compressor.
Check Limit Sensors
Check the function while drilling.
- 1.Check that the cradle is level with each limit sensor (A) as it stops.
Check Winch
- 1.Check for damage, unwinding, wear, and corrosion on the winch wire rope (A).
- 2.Check for damage, cracks, and wear on the hook (B) and check that it is properly mounted.
Check Remote Control
- 1.Check that the rubber bellows (A) on the switches and levers on the remote control are not damaged.
Check Hoses and Couplings
WARNING
High Hydraulic Oil Pressure
Working on the hydraulic system involves a high risk of personal injury.
Make sure that the system is de-pressurized before starting any work.
WARNING
Hydraulic Oil and Water Pressure
Can cause personal injury.
Do not replace high-pressure hoses with hoses of lower quality than the originals.
Do not replace high-pressure hoses with hoses that are installed with removable couplings.
- 1.Inspect all hydraulic hoses and connections thoroughly. Any cracking or swelling shows an external or internal leak. Inspect the hose location and clips.
- 2.Inspect the hose casing. Any swelling shows inner hose or cord breakage.
- 3.Inspect the hydraulic couplings for leaks, indentations, and adapters. The couplings must be fastened securely if they have screw flanges. If there are any signs of leaks around connections, replace the seals or the complete coupling.
- 4.Check that all hose retainers and clamps are not damaged.
- 5.Inspect all pressed couplings for signs of cracks or damage to compression sleeves. Replace any defective hoses with new ones.
Check Diesel Engine Control Panel
- 1.Check that no fault indicator lamp is ON in diesel engine control panel. In event of a fault indication, stop the machine, and rectify the fault.
Check Dust Collector
- 1.Check the filter in the filter holder, the suction hose, and the drill rod support drill gasket if there is dust formation.
