Description
Fairmont H6400C, H6400C1 and VSD6400 Reversible
Drills are intended for use with various types of bits for
drilling in wood, concrete or metal. All models feature a
geared chuck that permits the use of drill bits with shank
size up to 12 mm (1/2" diameter). Other features include
a directional spool for forward or reverse operation,
Super Spool™ for use on either an Open-Center or
Closed-Center hydraulic system, and an insulated
handle for operator comfort and safety. In addition, the
H6400C1 and VSD6400 include a removable auxiliary
handle. The H6400C1 also includes a pair of 305-mm
(12") whip hoses with quick-disconnect couplers.
Super Spool™ is protected by U.S. Patent No. 4548229.

SAFETY
ALERT
SYMBOL
Skin injection hazard:
Oil under pressure easily punctures
skin causing serious injury, gangrene
or death. If you are injured by
escaping oil, seek medical attention
immediately.
• Do not use fingers or hands to
check for leaks.
• Do not hold hose or couplers while
the hydraulic system is pressurized.
• Depressurize the hydraulic system
before servicing.
Wear eye protection when operating
or servicing this tool.
Failure to wear eye protection can
result in serious eye injury from
flying debris or hydraulic oil.
Read and understand all of the
instructions and safety information
in this manual before operating or
servicing this tool.

IMPORTANT SAFETY INFORMATION
Do not reverse hydraulic flow. Operation with
hydraulic flow reversed can cause tool malfunc-
tion. Connect the pressure (supply) hose and tank
(return) hose to the proper tool ports.
Failure to observe this warning can result in
severe injury or death.
• Remove the chuck key from the chuck before
drilling. Operation with the key in the chuck can
result in severe injury.
• Inspect accessories before use. Discard acces-
sories that have cracks, chips or gouges.
• Keep all parts of the body away from rotating
parts when the tool is in operation. Contact with
moving parts can result in severe injury.
• Do not change accessories, inspect, adjust or
clean tool when it is connected to a power
source. Accidental start-up can result in serious
injury.
• Maintain a firm grip on tool, using both hands at
all times. Serious injury can result if the operator
does not control the tool.
• Do not lock the trigger in the power-ON position.
The operator cannot stop the tool when the
trigger is locked.
Failure to observe these warnings can result in
severe injury or death.
Tool and accessory may be hot
during and after operation. Allow to
cool before handling, or handle with
heat-resistant gloves.
Failure to observe this warning
could result in severe injury.
Do not exceed the maximum hydraulic flow, pres-
sure relief or back pressure listed in the Specifica-
tions and Parts manual.
Failure to observe this warning can result in severe
injury or death.
Do not disconnect tool, hoses or fittings while the
power source is running or if the hydraulic fluid is
hot. Hot hydraulic fluid can cause serious burns.
• Wear protective gloves when handling, remov-
ing and installing drill bits. Drill bits can cut even
when stationary.
• Inspect tool before use. Replace any worn,
damaged or missing parts with Fairmont re-
placement parts. An improperly assembled tool
can malfunction, injuring nearby personnel.
• Inspect the hydraulic hoses and couplings every
operating day. Repair or replace if leakage,
cracking, wear or damage is evident. Damaged
hoses or couplings can fail, resulting in injury or
property damage.
• Use this tool for the manufacturer’s intended
purpose only. Use other than that which is
described in this manual can result in injury or
property damage.
• Ensure that all bystanders are clear of the work
area when handling, starting, and operating the
tool. Nearby personnel can be injured by flying
debris or by flying parts in the event of a tool
malfunction.

Note: Keep decals clean and legible. Replace decals
when necessary—see the decals listed in the
Specifications and Parts manual.
Procedure for connecting or disconnecting hydraulic
hoses, fittings or components:
1. Move the flow lever on the power source to the
OFF position.
2. Stop the hydraulic power source.
3. Follow the sequence under Hose Connections
to prevent pressure buildup. In case some
pressure has built up, loosen hoses, fittings or
components slowly.
Hydraulic oil can cause skin irritation.
•Handle the tool and hoses with care to prevent
skin contact with hydraulic oil.
•In case of accidental skin contact with hydraulic
oil, wash the affected area immediately to
remove the oil.
Failure to observe these precautions can result in
injury.
IMPORTANT SAFETY INFORMATION
Emergency stop procedure:
1. Release the trigger.
2. Shut off the hydraulic power source.

Setting the Super Spool™
The Super Spool™allows the tool to be used with
either Open-Center or Closed-Center hydraulic
systems.
Open-Center Hydraulic System
Use a wrench to turn the Super Spool™until the letter
“O”on the spool is aligned with the letter “C”on the tool
handle.
Closed-Center Hydraulic System
Use a wrench to turn the Super Spool™until the letter
“C”on the spool is aligned with the letter “C”on the tool
handle.
Setting the Super Spool Position
CLOSED - CENTER OPEN - CENTER
Installing and Removing Accessories
Inspect accessories before use. Discard accessories
that have cracks, chips or gouges.
Failure to observe these warnings can result in
severe injury or death.
1. Inspect the chuck. Remove any dirt or other con-
tamination.
2. Insert the drill bit far enough to allow full contact
with the chuck jaws, but not so far that the jaws
contact the flute of the bit. Hand-tighten by turning
the outer barrel of the chuck.
3. Insert the chuck key into one of the holes in the
chuck and twist clockwise to tighten. Repeat for the
other two holes.
4. To remove the drill bit, insert the chuck key into one
of the holes in the chuck and twist counterclockwise
to loosen.

Troubleshooting
Before troubleshooting, determine whether the problem
is in the tool, the hoses, or the power source. Substitute
a tool, hoses, or power source known to be in good
working order to eliminate the item that is not operating.
If the problem is in the tool, see the troubleshooting
table in this manual. If the problem is in the power
source, see the troubleshooting section of the power
source instruction manual.
PROBLEM PROBABLE CAUSE PROBABLE REMEDY
Tool doesn’t operate. Improper power source. Verify that the power source meets the
specifications. See the Specifications
and Parts manual.

erratically. temperature. Actuate the tool
intermittently to reduce the warming
time.

incorrectly set, limiting hydraulic fluid clockwise to increase flow until
flow. desired output is obtained.
Power source not adjusted correctly. Refer to the power source operator’s
manual. Set the flow and pressure
to correspond with the tool.
