12-2 Welding Precautions D20x22 Series II HDD MaintenanceSection 20: Maintenance - 10 Service Hours or Daily
MACHINE - GREASE
As a general rule, grease machine after it is shut down for the day. This protects the metal under the seals from
corrosion caused by condensation as the temperature drops.
Ensure all fittings and grease applicator nozzle are clean before applying grease. If any grease fittings are
missing, replace them immediately.
ENGINE MAINTENANCE
• Check fluid levels.
• Check air cleaner indicator.
• Perform walk-around inspection.
Refer to the Engine Operation Manual supplied with the machine for engine maintenance information.
FLUID LEVELS - CHECK
Check fluid levels daily before operating the machine. Also, inspect machine and
make any necessary adjustments and repairs before starting the engine. Refer to the
Engine Operation Manual.
Engine Oil Level - Check
With engine level, fill to full mark on dipstick. Do not overfill.

(1) Oil Fill Cap 1
(2) Oil Dipstick
D20x22 Series II HDD Maintenance 10 Service Hours or Daily 20-1Hydraulic Fluid Level - Check
Clean hydraulic fluid is very important. Do not spill dirt or other contaminants into
the tank. Filter all hydraulic fluid through a 5-micron filter before adding it to the
tank.
1
Keep tank filled to sight gauge level. Machine must be level and in transport position.
Refer to “Lubricants,” page 65-1.

Step 1: Remove fill cap (1).
Step 2: Fill to upper half of sight gauge level (2).
Step 3: Install fill cap.
20-2 10 Service Hours or Daily D20x22 Series II HDD MaintenanceCoolant Level - Check
WARNING: Hot fluid under pressure can scald.
Allow engine to cool before opening radiator cap.
Fill to within 1/2˝ (13 mm) of bottom of fill pipe with a low-silicate (ethylene glycol)
antifreeze and clean water mixture.
NOTICE: Never add pure antifreeze to a cooling system. We recommend using a 50/50
mixture. Never use high-silicate antifreeze or antifreeze that is higher than a 60/40
mixture.

ultra low sulfur content, less than 15 ppm or 0.0015% (15 mg/kg).
NOTICE: Use of higher content sulfur fuel will cause engine damage and
void engine warranty.
20-4 10 Service Hours or Daily D20x22 Series II HDD MaintenanceAIR CLEANER RESTRICTION INDICATOR - CHECK 2
When yellow indicator reaches the red area on indicator (1), replace air cleaner filter
element. Push button (2) to reset indicator. 1
• Do not remove element until the indicator shows it needs to be replaced.
• Do not wash or blow out element; it must be replaced.
NOTICE: The air restriction indicator will not function properly if:
• Element is damaged or not seated properly in housing.
• Air cleaner element body is damaged. If so, unfiltered air may be entering engine.
• Air transfer duct between air cleaner and engine is damaged or its clamps are
loose.
• Air duct between air cleaner and restriction indicator is damaged or pinched.
DRILL ROD CARE
Inspect drill rod before and during each use.
• Remove any rod from drill string with damaged or worn ends.
• Remove any bent rod from drill string.
• Use proper thread or profile gauge to check for damaged thread.
• After rods are coupled together, check for fluid leakage at the joint.
• Leaking drill rod joints indicate damaged shoulders, which will not torque properly.
• Check shoulders for dents, gouges, or high spots.
• Dress damaged shoulders with a file.
Do not exceed bend radius of the drill rod. Doing so will cause premature failure of the drill rod.
D20x22 Series II HDD Maintenance 10 Service Hours or Daily 20-5AUTO GREASER - ADJUST/CHECK/REFILL

SAFETY SIGNS MAINTENANCE
Safety signs located on your machine contain important and useful information that will help you operate your
equipment safely and correctly. Refer to the Parts Manual for identification and location of safety signs.
To assure that all safety signs remain in place and in good condition, follow the instructions given below:
• Keep safety signs clean. Use soap and water - not mineral spirits, abrasive cleaners, or other similar
cleaners that will damage the sign.
• Replace any damaged or missing safety signs. When attaching safety signs, the temperature of the
mounting surface must be at least 40°F (5°C). The mounting surface must be clean and dry.
• When replacing a machine component with a safety sign attached, replace the safety sign also.
Replacement safety signs can be purchased from your Vermeer equipment dealer.

WARNING: Pressurized fluid can penetrate body tissue and result in serious injury or
death. Leaks can be invisible. Keep away from any suspected leak. Relieve pressure in the
hydraulic system before searching for leaks, disconnecting hoses, or performing any other
work on the system. If you must pressurize the system to find a suspected leak, use an
object such as a piece of wood or cardboard rather than your hands. When loosening a
fitting where some residual pressure may exist, slowly loosen the fitting until oil begins to
leak. Wait for leaking to stop before disconnecting the fitting. Fluid injected under the skin
must be removed immediately by a surgeon familiar with this type of injury.
• Ensure all connections are tight and hoses are in good condition before applying pressure to the system.
• Check hydraulic cylinders for leaks and damage. Repair or replace as required.
• Examine condition of hoses. Check for leaking hoses, kinked hoses, and for hoses that rub against each
other or other parts of the machine.
• Replace all deteriorated or damaged hoses. When a hose with a protective sleeve is replaced, always
install a protective sleeve over the new hose.

Test Button Tests sensors, controller, and alarm
The alarm will sound briefly when the Test Button is pressed. A successful test is indicated when the green light
remains steady ON after the test button is released.
If there is a flashing green light after releasing the test button, the Strike Alert system is not functioning
correctly. Confirm voltage stake is fully inserted into the ground. The soil at the stake may need to be moistened
to improve conductivity of the earth. Retest the system. If the test fails to pass, contact your Vermeer dealer.
The Strike Alert system automatically runs a system check whenever the machine is powered up (ignition key
turned from OFF to RUN). The alarm does not sound during the power-up system check.
