GENERAL MAINTENANCE
McL-10H VERSA-MOLE
CARRIAGE
Check all screws and nuts initially and then every week when
in continuous use. Tighten all loose nuts and screws. Replace
missing nuts or washer.
HYDRAULICS
Check all hoses and fi ttings for leaks initially and then every
week when in continuous use. When tightening fi ttings, be care-
ful not to twist hoses from their original positions.
Relieve system pressure before disconnecting hoses.
Clean the quick-disconnects and install the dust caps.
LUBRICATION
Lubricate the cam rollers with 1-2 pumps of grease each week.
Lubricate the chain drive every 2-3 days when in continuous use.
Use the grease fi tting on the sprocket guard and use 4-5 pumps
of all-purpose grease. Rotate the spindle while greasing the
chain.
Lubricate the bearing carrier every 4-5 days when in continuous
use. Use the grease fi tting on the top of the bearing housing.
Use about 4-5 pumps of all-purpose bearing grease. (Photo 1)
Disassemble, inspect and re-pack spindle bearings every 1000
hrs or every 12 months.
CHUCK
Check threaded chuck, each day in use. Check for scarred
threads. NOTE: Always use an approved drill thread lubricant
on the chuck and drill rods to prevent damage to the threads.
Use Jet-Lube - KOPR-KOTE with CZ-EX or equivilent. (Photo 2).
Check hex chuck evey day in use.
Lubricate hex on augers and chuck with penetrating oil.
NOTE: If the carriage is submerged under water:
Drain sprocket guard by removing bottom plug.
Re-lubricate bearing carrier, 4-5 pumps of grease.
Re-lubricate chain, 4-5 pumps of grease.
FRAME
SHEET METAL GUARDS
Check sheet metal guards each day. Make sure that guards are
properly secured at the top and the bottom. DO NOT OPERATE
MACHINE WITHOUT GUARDS IN PLACE. Replace missing or
damaged guards immediately. (Photo 3).
CONVEYOR GUARDS
Check condition of belting material each day. Replace as neces-
sary.
THRUST CHAIN
Check tension on thrust chain each week. Tighten as required
using the bottom adjusting nut. The chain should be tight when
tapped with a wrench. (Photo 4).
LUBRICATION
Grease the thrust chain once a week. Apply a light fi lm of
grease to the top and bottom of the chain. The thrust chain must
be re-lubricated after each time it is cleaned with a pressure
washer.

MAKING AND BREAKING ROD JOINTS
Always use an approved thread lubricant on rods.
MAKING JOINTS
Insert the new rod into the existing rod clamped in
the breakout.
Rotate the rod 2-3 turns by hand to get threads
started.
Slowly position the carriage so the new rod
threads onto the chuck.
Rotate the spindle - but DO NOT THRUST - allow
the carriage to “walk” forward as the rod and
chuck screw together.
Run the machine over relief to tighten rods prop-
erly.
BREAKING JOINTS
Retract the carriage until the slider angle is even
with the rear notch in the side rail.
Activate the front clamp. Run it over relief.
Actuate the breakot cylinder. The joint at the
breakout should be loose.
Unscrew the rod about halfway out of the
clamped rod.
Retract the Float Indicator to the rear position.
Again, actuate the breakout cylinder.
The joint at the chuck should be loose.
Unscrew the chuck from the rod.
Fully retract the carriage.
Disengage the breakout.
Remove the rod.
IF FRONT JAW SLIPS, RE-ENGAGE TO FULL
SYSTEM PRESSURE.
IF JAWS SLIP, REPLACE THEM IMMEDIATELY.
(Photo 5).
Lubricate the pulley sheaves with penetrating oil. (Photo 6).
HYDRAULICS
Check for hydraulic leaks and tighten fi ttings as needed.
OPERATOR’S PLATFORM
Check that operator’s platforms fi ts securely on machine.
CONSOLE
HYDRAULICS
Check for hydraulic leaks and tighten fi ttings as needed.
Check guages for damage and accurate readings.
Check relief pressure setting. Run carriage to the front
or back of the frame and check the pressure on the thrust
guage.
SAFETY AND OPERATION MANUAL
Safety and Operation manual must be kept with the machine
at all times. Call McLaughlin Group, Inc. for a free replace-
ment.
GUARDS
Repair or replace guards which could restrict valve handle
movement or view of guages.
BREAKOUT WRENCH
Test breakout wrench each time before going into service.
Test Procedure:
Assemble (2) rods and insert them into the breakout.
Screw the rod onto the chuck.
Move the carriage so the rods are properly positioned in the
breakout.
Clamp the front rod in the front vise.
Tighten the rods with the spinde. Run the machine over
relief 2500 psi (172 BAR).
Break the rod joint with the rear cylinder.
Break the spindle joint with the spindle.
LUBRICATION
Grease cylinder pins with 1-2 pumps of grease. (Photo 8).
Grease jaw mounting blocks with cylinders extended.
JAWS
Inspect jaws daily for wear and damage.
Jaws that slip must be replaced immediately.
NEVER USE PIPE WRENCHES TO UNSCREW RODS.
BREAKOUT HOLD DOWNS
Hold downs must always be securely installed on the frame
rails.
CLEANING MACHINE
Clean machine after each use and before storing.
Clean all dirt off of machine.
Remove side panels and clean out dirt from around chains
