Stay away from rotating drill rod and cutting tool.
10-2 Safety Messages D60x90 Navigator HDD Maintenance
DANGER: Rotating drill string can kill. Unexpected start-up possible.
Lock out before working on drill string.
WAR NING: Keep hands, feet, and clothing away from power-driven parts. Keep shields
in place and properly secured.
WAR NING: Use Shutdown Procedure before servicing, cleaning, repairing or
transporting machine. Follow Shutdown Procedure, page 12-1.
WAR NING: Make no modifications to this equipment unless specifically recommended by Vermeer
Corporation.
WAR NING: Be sure that all safety devices, including shields, are installed and functioning properly
after servicing the machine.
D60x90 Navigator HDD Maintenance Safety Messages 10-3
WAR NING: When HEST (High Exhaust System Temperature) Light is displayed, the
exhaust gas temperature could exceed 1100°F (600°C) during regeneration. High
temperature may cause in fire, burn, or explosion hazards, which may result in personal
injury or death. Do not expose flammable material or explosive atmospheres to exhaust
gas or to exhaust system components during regeneration.
WAR NING: To prevent fi res, routinely cle ar any combustible material from the engine
exhaust system. Tier 4 Interim / Stage IIIB emission compliant exhaust systems use
extreme high temperature that can ignite combustible material.
WAR NING: Servicing machine during DPF regeneration can result in serious personal
injury. Avoid exposure and skin contact with hot exhaust gases and hot exhaust system
components.
WAR NING: If regeneration is performed within any indoor service/maintenance facility, ensure the
exhaust removal system is capable of withstanding temperatures exceeding 1100°F (600°C).
WAR NING: Fail u re to follow any of the prec eding safety instructions or those that follow within this manual,
could result in serious injury or death. This machine is to be used only for those purposes for which it was

Section 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.
MACHINE INSPECTION
•Inspect machine daily and check for leaks before starting.
•If stabilizer or rack hydraulic cylinders drift, contact your Vermeer dealer for repair.
•Check vise dies daily and remove accumulated debris or dirt. Clean with a wire brush.
ENGINE MAINTENANCE
Visually inspect engine daily and make any necessary adjustments and repairs before starting.
Refer to the Engine Operation Manual supplied with each machine for complete instructions.
FLUID LEVELS - CHECK
Check fluid levels daily before operating the machine. Refer to the Engine Operation Manual.

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.
Follow Shutdown Procedure, page 12-1. Check hydraulic fluid level.
Keep tank filled to mid-gauge level. Machine must be level and in transport position.
Use proper fluid. Refer to “Lubricants,” page 80-1.
Step 1: Open engine cover.
Step 2: Remove fill cap (1).
Step 3: Fill to sight gauge level (2).
Step 4: Install fill cap.
Step 5: Close engine cover.
Engine Crankcase Oil - Check/Fill
With engine level, fill to full mark on dipstick. Do not overfill.
Use engine break-in oil during first 100 hours of operation.
(1) Dipstick and Fill Cap
20-4 10 Service Hours or Daily D60x90 Navigator HDD Maintenance
Coolant Level - Check/Fill
1
WAR NING: Hot fluid under pressure can scald.
Allow engine to cool before opening radiator cap.
Do not remove overfill bottle cap (1) from a hot engine. Wait until the temperature
has cooled before removing the overfill bottle cap. Failure to do so can result in
personal injury from heated coolant spray or steam. Remove cap slowly to relieve
coolant system pressure.
Make a 50/50 mixture of coolant and distilled or deionized water. Add to cold fill line
when engine is cold; fill to hot fill line when engine is hot.
Radiator is located under the overfill bottle.
NOTICE: This machine was factory-filled with a 50/50 mixture of Shell Rotella ELC
NF (Extended Life Nitrite Free) coolant for -34° (-37°C) protection. Compatible
coolants include Chevron Delo ELC NF and Exxon Mobil Delvac ELC NF. Never add
pure antifreeze to the system; always dilute to a 50/50 mixture.
D60x90 Navigator HDD Maintenance 10 Service Hours or Daily 20-5
AIR CLEANER RESTRICTION INDICATOR - CHECK
1
2
Check air cleaner restriction indicator daily. When the indicator (1) shows a colored
band (usually red), filter elements must be replaced. Push button on top of indicator to
reset.
• Do not remove the element until the indicator shows it needs to be replaced.
• Do not wash or blow out the element; it must be replaced.
Refer to “Air Cleaner Element - Replace,” page 60-6.
NOTICE: The air restriction indicator will not function properly if:
•Element is damaged or not seated properly in housing.
•Air cleaner housing or element 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.
Air Intake Screen - Check/Clean
Blocked air flow increases engine temperature. Check air intake screen (2) for dirt
and debris. Remove screen and clean with compressed air or water.
20-6 10 Service Hours or Daily D60x90 Navigator HDD Maintenance
Dust Discharge Valve - Empty
1
1
Empty dust discharge valve (1) by pressing apart lips of discharge slot.
Remove any caked dirt by pressing together the upper section of the valve.
ACCUMULATOR PRESSURE - CHECK
WARNING: Accumulator is under pressure. Do not attempt to disassemble
or service accumulator. If accumulator requires service, contact your
Verm eer dealer.
Check accumulator pre-charge pressure on gauge (1) before starting the machine
each day. Machine must be shut down a sufficient length of time to allow hydraulic
oil to cool to ambient temperature and residual pressures in the hydrostatic closed
loops to bleed down to atmospheric pressure.
Pre-charge pressure should be 230–250 psi (16–17 bar). If pressure is too low, contact
your Vermeer service dealer.
Operation of accumulator without sufficient pre-charge can cause bladder failure.

DRILL ROD CARE AND INSPECTION
•Do not exceed bend radius of the drill rod.
•Do not over-torque or under-torque drill
rods. Doing so will cause premature failure
of the drill rod.
•Move leading rod to back of rod box after
each job to prevent excessive wear on the
lead rod.
•Inspect drill rod before and during each
use.
•Remove any rod from drill string with damaged or worn ends.
•Remove any rod from drill string that are bent.
•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.
